    Yes, but I was trying to find out how long it took the OPs battery to drain. Obviously, it would be quicker with the dome and interior lights on.

    This "battery draining" problem has been reported before. I can't remember the fix but this is not a normal thing. Any good battery should be able to play Ipods and radios 24/7 for a long, long time. Solid state electronics draw hardly any current from the battery. Your dealer should do some research. You too...get on the internet and see what you can find. This is not normal and there is a way to fix it.
  • There is a major design flaw in the Tahoe and Suburban LTZ models. I have a 2007 Tahoe LTZ and my dealer nor Chevy can figure out the problem. I just had my 3rd battery replaced today on mine. It has the same problem as your Suburban, it only takes about 15 minutes with the radio on, doors shut, key in the ignition (not in ACC mode) and the battery will drain to the point of needed a jump. According to my dealer, they think it is a bad module but can't determine which one. Any other ideas out there?
  • Do you remember what the recall on your transmission was?? I have an 07 tahoe and at 40,000 miles the transmission went out.
  • My battery drained 3 times using my iPod. Each time I needed a jump. The dealer checked out and found a fuse that was blown (they said from a bad jump), but didn't find out why the battery drained. Their advice was to not run the iPod with the car off. They told me all batteries would drain (after 20 minutes????). Was interested to find this site with others having the same issues. Called GM, have a case # pending, and I'm suppose to wait for it to happen again before I bring it to the dealer. Why can't the dealer do the diagnostics? What is the difference if I drain, jump and take in for correction? I don't think it's right that we have to accept this, but not sure how to escalate to get it corrected. Any one have a good dealer in the Chicagoland area?
  • Our 2001 Tahoe will not start under 30 degrees. The starter is spinning but will not turn over. The battery volt gauge shows 9 volts. I just replaced the battery with a new Interstate battery and we have replaced the fuel filter. Once it warms up outside it will start no problem. Any ideas, this is drivingus crazy.

    When you say the starter is spinning, but will not turn over..

    Do you mean that the starter properly engages, the starter gear engages the flywheel, and the engine crankshaft turns....but the engine doesn't start?

    or do you mean that the starter motor turns, but doesn't engage the flywheel and doesn't turn the engine?

    If it's the latter, then replace the starter.
  • I like many other unsatisfied GM owners bought a new Tahoe back in 2007. The battery now goes dead about once a month and I make sure nothing is left on.

    I checked out a friends Chevy pickup for the same problem and found when I put my meter on the battery the charge rate was good. Good amps and volts. I then checked the diodes with the same meter and found the diodes were shorted inside the alternator even though it was charging well.

    Once the alternator was replaced he had no more problems. The shorted diodes were draining the battery.

    I called the Chevy dealer where I purchase my vehicle new and they were certain the battery was dead and that would not be covered under warranty. They didn't even check it out, they just condemned the battery over the phone.

    GM must know what’s going on but do not want to pay for a recall!

    I will most likely change out my alternator myself.

    Your thoughts???

    So this vehicle sits not used, and after a month the battery is dead?

    Or you use this vehicle all the time, and mysteriously once a month the diodes short out and drain the battery down?

    Are you still signed up for the GM vehicle once a month call home function?

    I have an 07 LTZ, which is used primarily for long distance travel (like vacations) or 6+ people hauling, so it sits unused a lot. I (knock on wood), have not had any issues with the battery going dead.
  • I'm having the same problem. I just bought my Tahoe used over the summer. Here in Michigan with the cold weather, my truck won't start on avg. 4 out of 7 days of the week. Now I'm frustrated. Has someone actually changed out their alternator and solved the problem???
  • I drive my Tahoe every day without fail. About once a month when I go out to start it the battery is so dead it won't even unlock the doors.

    I know without a dought that I do not leave anything on.

    The wipers have never worked properly and the transmition has been replaced.

    Check to see if it fails, coincidentally the same date the vehicle 'calls home' to GM.
  • If I don't subscribe to the program you mentioned will my vehicle still "call home"? I don't use the OnStar or get updates of the vehicle health.

    Thanks

    If the battery drains after only 20 minutes then take your car to the dealer, park it in a convenient place (like right in front of the showroom door), turn the engine off and run your iPod. 20 minutes later you can tell them it happened again. :)

    I don't know, I unsubscribed to it.

    Just trying to think of some intermittent thing that could be coming on (or staying on).
    - if it calls home
    - air leveling pump
    - heated seats
    - turn in mirrors
    - auto tailgate close
    - HVAC
    - radio
    - etc

    I'd be pulling fuses, or taking care to go thru the same sequence of turning things off, looking for something out of oridinary.
  • LOL! PERFECT IDEA! Thank you tidester!

    You're most welcome. Let us know how it turns out. :)

  • Same thing happened to me, the alternator going out, at 62,000 miles. I changed the alternator myself in 20 minutes with only a 15mm socket and ratchet. Not that hard to do.
  • I'm very interested in learning more from others who have had the same battery drainage problem on their 07 Tahoe like I have. For the last 6 months or so, my battery (80K miles) has started doing just what others here have described; I leave it off for 2 or 3 days at most with nothing plugged in or anything left on, and it completely drains, or I leave the interior light or radio on for 30 minutes while sitting it it and it totally drains. A jump works but then the computer is all messed up and reports random issues on the instrument panel for a day or so, and sometimes the radio, Nav, and other electronics don't work at all. After a day or so of driving and recharging the battery, everythign usually mysteriously starts working again. My main question is whether this is something covered under the 5 year/100K Chevy owner's warranty, or if it's again one of those things that is only covered under the 3yr/36k bumper to bumper warranty? If not, has the alternator replacement really fixed the problem? I read the post about the possible BCM and electronic remote starter reprogramming issue that GM issued possibly resolving this, but my experience with my local dealer has usually been a dogfight to get anything covered - they pull the old "well, if you agree to pay for some other services you don't really need (at double the reasonable price I might add) I might be able to cover it [insert issue here] and get it fixed under warranty" trick. I'm tired of having to fork over money for services that I don't need or that I can get done for half the price elsewhere just because I need a warranty item addressed. Just as an FYI, I've had other issues with my 07 Tahoe like some of you on this site including: 2 blown transmissions (I'm on the 3rd now); random audio/Nav/DVD system issues that cause all Audio/Nav/steering wheel controls to stop working including anything to do with turn signal and flasher audio since its tied to the stereo apparently; a rear A/C system failure that took 5 trips to figure out and finally fix correctly; and even little annoying things like the cheap plastic chrome covered interior front door handles cracking and peeling so much that they are like little razors that slice my hand every time I reach for the handle (finally had to sand them down and cover with electrical tape until I get replacements). Overall, this vehicle has been way too much trouble than it was worth given the $51K I paid for it. Likly my first and last Chevy.

    Has anyone who has replaced the alternator successfully fixed the battery draining problem? If so, I may end up doing that myself as I suspect I know what my dealer will tell me, which is, "gee, we ran some diagnostics on the charging system and it all checks out, so you're on your own."

    MY battery would be completely drained after sitting overnight. I jump start it and it would be fine and i can stop the vehicle and start it up again. I did an amperage check and the vehicle was drawing 3+ amps with nothing on at all. We have had weird things happen with the radio so I figured that the radio might be the reason. I pulled the fuse for the radio and problem solved but I have no radio now. My bumper bumper warranty is expired. This is the second radio that I have had in the vehicle. The first one was causing engine whine through the speakers

    Take your vehicle and have the battery and alternator load tested. Most auto parts chains will do that check free of charge. Replace anything not up to snuff.

    If those check out okay, then there is something that is draining the battery, and you will need to have an electrical shop test for parasitic current drain.

    I didn't see any details in your message...I hope your laptop's battery didn't die ;)

    Anyway, here's a good tutorial on this sort of problem. I hope it's of help to you:

    I am having the EXACT same problem. Just wondering if you have any new info? I am sooo frustrated!!

    I haven't found a solution to the problem but when I took my Tahoe in to have a BAD wheel bearing replaced I did get the service adviser to admit GM knows about the problem but are admitting to nothing. The Cadillac Escalade is having the same problem. As I mentioned in one of my earlier posts, GM knows, they just won't admit to the problem because they don't want the expense of a recall to fix it.

    Good Luck!
  • I used to have a 2007 Tahoe LTZ with the exact same problem; however my dealer did solve the problem back in December when he had the Tahoe in the shop for 8 days. Their is a bulletin that GM released in April 2009 that pin points the problem to the High Speed Bus Bar which is located on the firewall on the passenger side. This is a defective part which overheats. In return it simulates a fake dead battery. Many shops look to the battery as the problem when in reality the battery is fine. Both my dealer and I could not simulate the problem again after replacing this part and following the action steps in the bulletin. Good Luck.
  • I had a similar problem on my 07 LTZ, so I replaced the alternator and it solved the problem. Turns out the alternator wasn't charging the battery fully when running, so I was draining the battery each time I drove it. However, the alternator never actually failed so I never thought it might be the issue. The other clue was that when the engine was running every light on the vehicle would pulse due to uneven amps coming out of the alternator...

    I have also been having battery issues in my 07 Tahoe. Started about a year ago, had the alternator replaced. Seemed to fix the problem but not for long. I could stop and get out of the car, run into a convenience store for a coke and get in and dead as a door nail. Other times it would be extremely slow to crank and then it would go for 2 months without another episode. I did find a recall on 07 Tahoes for a fuse problem with the washer fluid heater elements that was credited for a variety of electrical shorts, but I was told mine didn't have the right VIN number for the recall. My charging gauge fluctuates up and down and the cd changer will sound like its stuck to name a couple other symptoms. I will take one of the earlier comments and ask my dealer about the high speed bus bar. I have to say I was surprised to find so many are having issues especially with the 07 model. Best of luck on resolving your issues.

    I live in Brooklyn N.Y. I drive my tahoe every day ,yet I am no different from these tahoe owners I have heard from today.My tahoe has been giving me problems starting for the last year and a half.Like others I thought it was because my girlfriend kept leaving the radio,heat or ac on. I spent $100 on a portable battery charger,then bought the $185 battery that is compatable with the tahoe.That was 2 days ago.Today I used my battery charger.THIS IS BULL i will keep it clean but it will be going to the mechanic 2day!Just wanted to share cause if not for u guys I would have thought it was just me! :mad:

    Hello,
    I am from GM Customer Service. Is the vehicle still under warranty? Has the battery been looked at for its battery cell level? Have you taken the vehicle to a dealership to have it diagnosed? What is the VIN of the vehicle? You can direct message me if you prefer with your information. Thank you,
    Mariah GM Customer Service
