Chevrolet Tahoe Electrical Problems

145679

Comments

  • We bought this Tahoe a year ago from a dealership in Lancaster, WI. Up until a month ago, everything was great. Solid vehicle. Now though, all of the above described electrical gremlins have occurred. For my wife, this is very frustrating as our 2001 Suzuki XL-7 with 200k miles had less problems. We have an appointment with our Chevy dealer in LaGrange, KY this Friday to have the vehicle looked at again. It has 30k miles on it.

  • Amber,
    What exactly does "look further into this for you" mean? If GM was actually concerned and wanted to look into this all they would have to do is read this forum of over 400 posts about pretty much the same issues and get a good idea of what's going on. This is only a small sample size on 1 website. There are many others as well.
    The truth is they know exactly what's going on and it is unfortunately going to take auto fatalities before someone really gets their attention on it. So in the meantime, owners will have to figure out most of these issues on their own with the help of each other or buy another product before their vehicle strands them or worse.
    It is really a disappointment to see such a lack of concern on these issues.
  • I agree unless there are some fatalities and lawsuits started then nothing is going to happen..even the dealer I went to said that they won't do anything because there aren't enough people with the problem.
  • Dealer has had the Tahoe for a week now with the technician using it as his daily driver with my blessing. Hasn't acted up yet. Will update again end of next week.

    I have a 2009 certified preowned Tahoe LTZ that I purchased in December 2012 with an extended warranty. I am having the problems of:

    - radio turns off and back on again (about 3 seconds)
    - abs light blinks during this time (about 3 seconds)
    - traction control light comes on sometimes (about 3 seconds)
    When those things happened I recorded the event on my iPhone ironically while going to the dealer to report this yet again. I showed the video to the service advisor. He said that they the tech still had to see the car do it! This was at Love Chevrolet in Columbia, SC.

    - at times when switching the car off, the doors will not unlock unless you switch the car on again or manually unlock the doors.

    - in late June 2013, one morning the battery was dead. Jumped the vehicle and took the battery to get it checked and it recharged fine after driving. No accessory was on at the time.

    -one time (July 7, 2013) while driving at 70 mph on the interstate. The lights started going off with bells and the radio reset as usual, but this time the speedometer went to 0 mph for about 3 seconds.

    - have taken the vehicle to dealer 3 times with problem. They have no clue.

    As of today, July 10, 2013, the vehicle has been at dealer for two days and counting. The dealers says that the technician has to see the problem. So, they are driving my car every day, while I pay the note and fill the tank with $85 of gas! What a good deal for them!!

    see the YouTube video for yourself:

    2009 Chevy Tahoe Dashboard Disco (the lights and bells go off wildly!)"
    The video is about 1 min. The disco is about at the end of the video.

    Amber,
    I most certainly will update the post in this thread! Thanks.
  • kmg10kmg10 Posts: 8
    Love Chevrolet in Columbia, SC called me back today and said that they could not see the problem. They called GM and said that GM said to replace the battery cables through the warranty. However, the electrical problem damaged the battery and they said that the charge is $150 plus labor to replace he battery. However, the electrical problem causes accessories to run the battery even after the ignition is off. They didn't care about it. They said the battery would be my cost. Go figure that! Sounds like "buck passing" to me!!

    Yea, that's not going to fix your problem. I recently found this technical service bulletin. I'm going to give it a try and see if it works, so I'll let you know.

    Kmg10, I had the same problem with my 2008 silverado. I replaced the master fuse, ECM, switch in the steering column. After all of those the problems still existed. Finally broke down and took it to the dealer and they replaced the battery cables in October 2012 and haven't had a problem since then. Not sure if your truck will have the same result but I thought I would let you know of at least one success story. Take care and best of luck.

    Bran164,
    Thanks for the heads up. They changed my battery cables today. We will see how it works. Thanks!

  • We got our Tahoe back yesterday with the battery cables and VICM (Vehicle Integrated Control Module) replaced. The technician was able to experience what we did while out driving and pulled three fault codes out of the computer; B1010, C0900 and B1325. What they found was the VICM shorting out internally. GM confirmed they have been experiencing issues with this and gave me a case # of 71-1201978849. Fingers crossed this fixes the issue.

    Did you ever get this problem resolved? I'm having same issue.
  • ag75ag75 Posts: 8
    No, I never did. Ended up trading it in at a dealership. My mechanic spent many many hours and even took the time to talk to other mechanics that people on this forum were using to try to find a solution. After several thousand dollars and no help from GM we finally gave up. Our family was just not safe in the vehicle any longer.

    I wonder how I can get in touch with Scuba_steveo on here. I'm actually having the same problem as him with the sporadic no start, everything is completely dead, and there is clicking in the door panels when this happens. We have to touch/jiggle cables on the baterry to get it going.
  • I have my 2002 suburban 1500 since new and luv it...very few issues until lately. I have the same issue with the accessories running the battery down with ignition off. It's been troubleshot to the stereo system and confirmed by pulling the fuse. Not sure how replaceing battery cables would help. Does anyone have some advice? Thanks
  • kmg10kmg10 Posts: 8
    In addition to replacing battery cables, they also reprogrammed the modules. I think that there are about 5 or 6 modules. On my vehicle, 2009 tahoe, the weird voltage fluctuations may have disrupted/corrupted the modules' memory chips. Pure speculation, but just a thought.
  • When I first got my 2008 Tahoe... if the truck sat for a day or 2... I would go to start it and nothing. Eventually the problem was due to my radio never completely turning off... and of course I didn't know... since it was something behind the radio. Anyway... I had to get a new radio and that fixed the problem. BTW... I will never buy a Tahoe ever again... or a GM product as far as that goes.

    I have a 2009 Avalanche and I have experienced several times the problems described multiple times in the posts above. The entire electric system goes on/off while driving and you can hear the door locks going on and off, the battery suddenly dies, the abs light comes on without reason etc..
    Went back twice to the Chevy dealer in Melbourne Florida and they could not find any codes related to those issues. ( I wish I had seen this thread before). I believe that I know part the cause and the fix to this: The positive cable connection to the battery post is simply crimped in a metal connection of poor quality. After a while , some oxidation occurs between the copper ( I believe) cable and the metal of the post connection. The oxidation build up is enough to create the power failure. The cable appears to be firmly connected to the battery, so the mechanic doesn't think that there is anything wrong. This is also why in some occasions, just tugging or moving the cable will restore the connection sometimes for several months ,until the oxidation builds up again. Of course, replacing the cable will work, but it is less expensive to just buy an old style battery post connector where the cable is pinched with 2 bolts.
  • I recently experienced this known electrical issue for the first time yesterday. I just had my Tahoe at the dealer last week for a strange clacking noise under the hood. They stated I would just have to wait until it did it again. Yesterday everything went haywire and my Tahoe appeared possessed. Door locks, gear shifting abnormally making it difficult to drive and steer due to steering column stiffness and loss of power steering which could have caused serious risk to others around me and my two children in the car.

    Turning to the internet and finding that I am one of what is probably thousands complaining of the same issue makes my extremely concerned that GM is not looking out for its current and future customers. I will be filing a complaint with the Attorney General's office with the state of NC immediately.

    Not only have we dealt with this issue. We have long dealt with the oil consumption issue that GM continues to say is "normal" consumption. Extremely disappointed in GM and how they are handling MAJOR component issues. We also own a Jeep Wrangler and they are been absolutely amazing anytime we have an addressable issue.
  • It's been about 2 months since the battery cable change, and that seemed to have fixed the problem. At least, I hope it has.
  • Update to this fix. While replacing the VICM module did fix the problems, what it also did was start sending erroneous readings to my ONSTAR app on my smart phone. For instance, it is telling me that I'm getting 166 mpg with a fuel range of 4016 miles until empty. I called ONSTAR and had one of their engineers call me in which I was told this is a common problem across the fleet for both GMC and Chevy vehicles that have had the VICM replaced. Due to the module not being the original one, the new module is not able to talk correctly with the vehicle. Hence why it is sending bad information to the ONSTAR app. I asked why this wasn't fixed as it is a simple software solution. The engineer said that GMC is well aware of the problem but has decided not to throw money at it. Anybody else having this issue?
  • A little experience that I have tells me that maybe your body control module may need to be reset or replaced. The bcm control many of your electrical workings such as clock, radio, outside mirrors, and reading you key and sending a message to start the engine. These things don't stop working, they just act up. The bcm controls many different things! Hope this helps.
  • I too have had issues with electrical system, It would go completely black, no onstar, no power even for door locks. H
    ad it into dealership at least 10 times no solution. I did discover if I wiggled the ground cord behind the battery it would turn on the power and it would start. The dealership replaced it and a lot of other modules. I thought it was fixed but now I am seeing the same crap again. I just replaced the battery again. I think something must be draining it slowly as if I leave it for more than five days it is dead. I am mad my extend warranty is over and now I am stuck paying for a problem that should have been fixed. It seems from the look of this forum I am not the only one, Come on GM step up lets find the problem recall and fix it.
  • i just purchased a certified Pre-owned 2009 Chevy Tahoe LT and i am having the same problems. I have only had the car for 2 weeks. It is at the dealer as I write, and of course they have not found anything wrong with the vehicle. Have you come across a solution, or any suggestions. Thanks

    Bobby,
    Look at my post from July 10, 2013. I have a video of the problem. GM said to replace the battery cables, as the stock cables are not rated large enough to carry the current load when you accelerate. Thus, causing the voltage to fluctuate. You may need to reprogram the body control modules as well. Sometimes their memory gets messed up as a result of the voltage problems. Hope that it helps. My 2009 has had no problems since the fix. "Knock on wood" Good luck to you.

    Mark
  • Thank you so much for your response! I spoke to my dealer and sent them the info. They are changing out the battery cables for me at no cost. Im still trying to convince them to reprogram the body control modules, or at least check them out. Thank you again! This was driving me crazy
  • 2011 Tahoe LTZ 43k- Major frustration with a repeated DEAD BATTERY!! It happened about 8x over the past 3 months. Drive to store....go into the store..back out and its DEAD! Jump it and drive home and its fine for a while. No rhyme or reason!! It happened this sunday and again tuesday so i took it in to a local shop for a new battery. They tested the battery w car on and off 13.8v, starter and ignition checked out as well. I see that battery issues seem to be pretty common.....any real solution to this headache?? thx Brian

    Are there Chevy reps on this sight?

  • Thanks for the post traveler2012 and everyone else here. Experienced the same thing with my 2008 GMC Sierra. Was traveling down the interstate and my power locks, radio, gauges went haywire for a few seconds and went away. Did this a few times over a two week period and didn't treat it seriously enough to take it in until it lasted several minutes on my way to work on day. I recently had the battery replaced with an Auto Zone battery so I took it back to the shop that did it for me. They were scratching their heads until I found this forum while I was waiting and shared it with them. The terminals on these batteries are smaller and caused a bad connection. Has only been a short time but haven't had any more issues.

    Thanks again for everyone posting this and I maybe someone with a Sierra issue finds mine and it helps them.

  • I have a 2009 LTZ. I have not had any issues while driving. However, two times last month I went into the truck to start it, and everything appeared dead (except the battery was fine). I also had the rapid clicking of the doorlock solenoids. Several posts on here mentioned the same problem. Both times I was able to get everything working again by disconnecting the battery, waiting 15 minutes and reconnecting (resetting all electronics). My problem seemed to be initiated with the slamming of the passenger door or the power passenger running boards going up. After reading other posts on here, I inspected all battery cable connections...and they seemed fine. But I decided that I didn't like the Negative Battery Terminal connecter, as it is a 1.5" machine crimp. Even though no corrosion was visible on the outside, I cut it appart with my Dremel tool. The copper wire was greenish/black at the two pinch points (all of the way around), and the connecter metal was brownish/black rather than grey. It wasn't the worst corrosion I've ever seen, but it definitely looked like the root of my problem. I replaced the terminal connector with a $4 part from Autozone, and cleaned/sealed the connection. I have been fine for two weeks. I will respond again in a month or two to let you all know if it is still working. Thanks for all of your comments and advice. If this continues to work I'll be writing a letter to GM identifying the problem and how quickly/cheaply it could be recalled/corrected for people. If this doesn't fix it, I will commence war on GM.

  • For some reason I could not get into my old account, but here is the issue I've been having that was posted a while back...

    "Mine is having the same issues while driving, door locks going up and down, gauges moving back and forth, lights flickering, sometimes the tahoe shutters, and this usually happens anywhere from 3-10 seconds. And when this does occur, when I get to my destination and shut off the car, then it always goes completely dead. Then I can hear a intermittent clicking noise coming from the door locks and under the dash, but nothing works at all. I always disconnect/reconnect my battery cables, and it always temporarily solves the problem. This may happen a couple of times a day or it may drive normal for a month or so. I bought the tahoe used in april 2012, and it did this off and on until around oct 2012. Then it ran perfect up for about 6 months, and now yesterday it did it again."

    A few weeks ago I discovered that I don't actually have to disconnect the negative battery cable, but if I just grab the negative cable and pull on it, then all power comes back like nothing ever happened. The only thing that could be affected by pulling on the cable, is the cable itself or the Battery Current Sensor. The battery current sensor is located about 10-12 inches down the cable from the battery. I think that the sensor was giving incorrect current signals to the ECM. I inspected the battery cable, but could find no corrosion, nicks, cuts, or anything, but I went ahead and bought a new negative cable ($11) from NAPA. I also bought the Battery Current Sensor from the Chevy dealer, and surprisingly, it was only $22. So far, I haven't had anymore hiccups, but seeing as how my problem has been so random, we will see...

    I have a 2009 Tahoe LTZ with 85,000 miles and put in a brand new battery December 2013. About a month ago, the truck was completely dead one morning other than a clicking electrical noise coming from the driver's door panel. I was able to jump start it and hadn't had any problems again until a few days ago. Now, several times over the last few days, various warning lights will come on in the dash (seatbelt, traction control, air bags), the radio will go dead and the headlights will flicker, and it loses power and steering for a few seconds. It seems to happen when I'm applying brakes or turning corners. I'm very worried about this happening at highway speeds and know I need to get it fixed! Has anyone figured out the problem yet? I'm not sure if I should take it to a GM dealer...it doesn't sound like the dealers are any help. I've read this entire forum and would appreciate hearing from those of you that have tried the various fixes and found any long term/permanent fix - battery cables, battery terminals, alternator, starter cable, OnStar, mega fuses, BCM, GMLAN system, VICM, clear codes and reset computers. Please help! I live in San Antonio, TX if anyone knows of a good electrical specialty shop here.

  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490

    Sounds like your car's various computers are not getting proper voltages--which drives them crazy. I think you have a charging system problem (you can easily have alternator output tested) and of course, checking all battery cables (especially grounds to the battery and the PCM) is essential.

  • jsegrovesjsegroves Posts: 1

    I have a 2010 Tahoe and having electrical problems. The voltage gauge on the dash drops to around 12-13 volts and all the circuits begin to go crazy, The door locks will lock and unlock and the dash gauges will flicker. I had the alt tested and the only thing that it showed was the CCA was a little low. Once the alt gauge got back over 14 it did not have any other problems. Anybody else had this type of issue?

  • gmcustsvcgmcustsvc Posts: 4,252

    Hopefully you're able to get some good advice here on the forum, jsegrove. Please let us know if you're interested in visiting your dealership for further assistance. We'd be happy to reach out to them to further discuss your concerns.

    Replace the battery current sensor, $22 at the dealership. It's located on the negative battery cable.

  • Thanks for posting traveler2012. Our electrical problem started after replacing the battery with a auto zone battery. I will recheck batter connectors for tightness and engine block to firewall grounds. It also sounds like an auxiliary ground from battery neg. terminal to the frame is also a good idea. I'm surprised that GM hasn't jumped all over this and stated that the smaller terminals on aftermarket batteries should be checked. The number of women with children should have initiated an immediate blitz to the dealerships and other repair facilities. GM needs to be proactive about their reputation, especially with the Govt. bail out still fresh in peoples minds. Why lose a potential future auto sale for $30 to $60 in parts. After the frustration level is at a pure boil it is too late not o lose them to a foreign car maker. I know my misses is hot about this issue on her 08 tahoe. Women don't like being stranded and all the technical talk in the world won't erase the experience for them of the helpless stranded feeling. It was said at one time that what's good for GM is good for the country. I'd like to pose a modification for the GM Management to Tattoo on their brains... What is good for the consumer/customer is Good for GM in the long run. Looks like that would be a no brainier even for those with a Ivy League education. Don't continue to lose market share to other manufacturers over stupid failures in customer support. If you screw up... admit it, fix it, build good will think of future sales... I've worked in dealerships where service drove sales... win/ win for all

    When my husband and I purchased our 2009 Chevy Silverado, less than 30 days ago, there was an initial problem with the back passenger door lock not opening and closing and the next day, after we purchased the car it stalled in the Orchard Supply Hardware parking lot. We discussed both issues with the dealership immediately. The dealership replaced the actuator, and ran a diagnostic. However, I’m wondering if the initial door issue and car stalling was part of a bigger safety problem which manifested itself during the mentioned major malfunction.

    On Monday, September 29, the truck again encountered a problem, but this time I experienced two major malfunctions, within 15 minutes, while I drove home. It happened twice within 15 minutes. Both times I was approaching an intersection and went to accelerate through the intersection when the truck lost power to the engine, and the engine seemed to turn off.

    I was forced to coast to the side street and avoid being hit by the cars behind me. Both times I couldn't get the truck to accelerate for about a minute. During that same minute the door locks on all doors were popping up and down and the indicator lights on the dash board briefly flashed on and then off.

    I called my husband and he came and followed me home. On the way home the dash lights turned off and I could feel that there was a decrease in acceleration, but I was able to make it home.

    Once home, called the Chevrolet Customer Service (1-800-222-1020). I told the agent on the phone what safety issues I had encountered. She called the dealership and got me a FREE diagnostic and 1 hr. labor to investigate the issue. I also looked up on the internet the car issues I just encountered and found the EXACT same issue with the 2008 Chevrolet Tahoe within this forum.

    I took the information I found, printed it out, as well as emailed the information to the service manager at the Chevrolet dealership where I had the appointment scheduled.

    I've pasted 2 links below to let you know where I got my information from.

    http://www.autoserviceprofessional.com/article/92084/finding-gmlan-wiring-problems

    http://forums.edmunds.com/discussion/5662/chevrolet/tahoe/chevrolet-tahoe-electrical-problems/p9

    Well, I took my truck in for the scheduled appointment today. This is what the report said:

    "Tech inspected & found C0900 stored. Tech followed published diagnostic & found the UBEC cable/175 AMP maxifuse has fretting issue. Tech replaced the fuse/cable & tested. Tech also found the neg battery cable have excessive voltage drop.
    Tech found the UBEC cable/fuse has fretting problem & the negative cable has excessive voltage drop.
    Tech states the negative battery cable has excessive voltage drop cause: customer satisfaction
    Battery positive junction block cable replacement
    Tech found the negative cable has a 256 MV drop. Tech replaced the negative battery cable & tested. Tech states the cable now operates to Manf Specs."

    My husband picked up the truck this afternoon. The service technician said that the notes I emailed and turned in helped them narrow down the problem and pinpoint it without much delay. No fees or charges. I hope this information assists others and thank you to the others that posted their problems and solutions previously on this forum.
  • Does anybody have the same problem. I am experiencing the same problem with 2013 Tahoe. While driving 4 times now, dash and radio screens go completely blank and back on with in seconds, locks lock and unlock in same cycles. Engine loses and regains power during cycle. This will go on for up to 10 seconds, then every thing drives normal with no code lights on. Took it to the dealer, they put it on computer and drove it 70 miles, the mechanic says it drives like a dream. One blog asked if the computer resets itself due to power failure wiping out memory record.
    I am now mounting a camera inside to capture the moment, if it happens again.

    One thing they said they did, was clean a ground. Not the main ground, but one to the dash. This makes sense because these cars are made of plastic and need more grounds then in the day. They acted like they did not think this was the problem though, said that ground looked OK before cleaning and tightening.

    Just had this issue pop up last week on our 2011 Tahoe.  Took in to dealer and first thing service advisor said it's that there has been issues with the negative cable.  437.00 later it's been ok so far.   I've also logged a complaint with GM that this should be a recall but if they attract going to get enough formal complaints that won't happen.   Email GM everyone so we can get out money back and this can be recalled before it causes accidents and injuries

    Pretty sharp mechanic, though, you have to admit.
  • Fortunately, I don't have the problems with the random stopping, but my 2006 randomly won't start. Had full tune-up (wires, plugs, belts) done about 10K miles ago. Now I have an issue where the Tahoe randomly just won't even turn over - like the battery isn't there. Get out, disconnect the battery, reconnect and it will start. Can't get the code to stay on for dealer - so to them there's no issue. At a loss....... don't know where to start troubleshooting this thing.

    I have a 2013 Tahoe LTZ and I have been having the same issues as many on this blog. My gauges start going haywire, losing power to the transmission, door locks cycling and dinging as warning lights go on and off intermittently. Sometimes it dies on me and won't start and after I let it sit all night it starts right up. It will start with check engine light and then will not shift out of low gear. I had it towed to a dealer and they could not get it to act up. They told me to come pick it up and I could not even get out of the parking lot before it started jerking and loss of power etc. I had a sales manager come out and see what it was doing so I left it at the dealer and next morning it was fine. After 2 weeks at the dealer and $500 in car rental later I picked it up and got it home with no problems. This week on spring break it broke down on me in the middle of Texas on my way to Colorado. I was not happy. The next morning, it started and I drove my daughter the rest of the way to Colorado in low gear. I took it to a dealer while it was acting up and they could not pull codes because there was no communication with the computer. They rushed it back to the big computer and before it was able to read the 4th code it was running fine. After pestering the dealership about me having to leave for home so I could get my daughter back for school they test drove it and low and behold it died on them in the parking lot and they had to push it into the garage...much safer than when it died with my daughter in the car in the middle of Texas. After that I got a phone call saying that in their frustration they hit the fuse box under the hood and the car started up, they hit it again and it died. After inspection they found that there was massive amounts of corrosion in the fuse box and connections were corroded and they think that is why my 2013 Tahoe has been intermittently acting in this manner. I will find out soon if that was the culprit. I would have thought the fuse box under the hood would be sealed? Very frustrating to say the least

    Did this ultimately fix the problem?

    When my husband and I purchased our 2009 Chevy Silverado, less than 30 days ago, there was an initial problem with the back passenger door lock not opening and closing and the next day, after we purchased the car it stalled in the Orchard Supply Hardware parking lot. We discussed both issues with the dealership immediately. The dealership replaced the actuator, and ran a diagnostic. However, I’m wondering if the initial door issue and car stalling was part of a bigger safety problem which manifested itself during the mentioned major malfunction. On Monday, September 29, the truck again encountered a problem, but this time I experienced two major malfunctions, within 15 minutes, while I drove home. It happened twice within 15 minutes. Both times I was approaching an intersection and went to accelerate through the intersection when the truck lost power to the engine, and the engine seemed to turn off. I was forced to coast to the side street and avoid being hit by the cars behind me. Both times I couldn't get the truck to accelerate for about a minute. During that same minute the door locks on all doors were popping up and down and the indicator lights on the dash board briefly flashed on and then off. I called my husband and he came and followed me home. On the way home the dash lights turned off and I could feel that there was a decrease in acceleration, but I was able to make it home. Once home, called the Chevrolet Customer Service (1-800-222-1020). I told the agent on the phone what safety issues I had encountered. She called the dealership and got me a FREE diagnostic and 1 hr. labor to investigate the issue. I also looked up on the internet the car issues I just encountered and found the EXACT same issue with the 2008 Chevrolet Tahoe within this forum. I took the information I found, printed it out, as well as emailed the information to the service manager at the Chevrolet dealership where I had the appointment scheduled. I've pasted 2 links below to let you know where I got my information from. http://www.autoserviceprofessional.com/article/92084/finding-gmlan-wiring-problems http://forums.edmunds.com/discussion/5662/chevrolet/tahoe/chevrolet-tahoe-electrical-problems/p9 Well, I took my truck in for the scheduled appointment today. This is what the report said: "Tech inspected & found C0900 stored. Tech followed published diagnostic & found the UBEC cable/175 AMP maxifuse has fretting issue. Tech replaced the fuse/cable & tested. Tech also found the neg battery cable have excessive voltage drop. Tech found the UBEC cable/fuse has fretting problem & the negative cable has excessive voltage drop. Tech states the negative battery cable has excessive voltage drop cause: customer satisfaction Battery positive junction block cable replacement Tech found the negative cable has a 256 MV drop. Tech replaced the negative battery cable & tested. Tech states the cable now operates to Manf Specs." My husband picked up the truck this afternoon. The service technician said that the notes I emailed and turned in helped them narrow down the problem and pinpoint it without much delay. No fees or charges. I hope this information assists others and thank you to the others that posted their problems and solutions previously on this forum.

  • Hello everybody, my 2008 Tahoe shut down yesterday after I switched from 2W to 4W high. I was on a road covered with a huge block of ice and I was about to slip in a deep valley with my 2 kids. Any idea why this happened? The Stabilitrack and traction control lights are on.
