    Have you gotten any of this resolved? My husband recently had a similar experience with his airbags deploying on a gravel road in a 08 Chevy silverado and Chevy says that the pickup is only designed for paved roads ?!?!. We are going to have to have our insurance company pay but he is concerned about it happening again.
  • 2004 6 cylinder Silverado with 120,000 miles on it. Had a tune up at 96,000, new battery, points& distributor at 108,000.

    Engine light came on and the error was "Random Misfire" The injectors were cleaned but didn't solve it. Cylinder 1 misfires at 1800 rpm (60 mph). A pressure test was done on the injectors and 5 of them came out at 13.9 and the misfire cylinder was 13.7.

    Problem not fixed.
    Mechanic said one idea would be to replace the injector on #1 ($500) but could not be sure that would solve it.

    Any ideas??
    Thanks

  • Next week we will be taking our truck to the dealer to have it checked out. Prior to taking it in, I wanted to see what others with similar experiences have found.

    Early this year we fell in love with and purchased a loaded 2009 LTZ Silverado Crew Cab 4x4 that was Certified by the dealer. I would say 95% of the miles I have put on the truck are highway miles to and from work (40+ miles one way).

    Of a morning, usually at my second traffic stop, I am almost certain there is a very brief flicker of the headlights. Several afternoons when I have exited the expressway, it feels like the temperature of air from the a/c changed warmer then cooled back off. Off and on I have heard chimes but they have usually been of an afternoon in traffic so I have not been able to see what was being displayed. Last week I heard the chimes numerous times over several days. I was finally able to see the message being displayed was that the parking assist was turned off. I did not turn it off and was unable to get it to come back on. This week it seems to be on and working.

    Over the weekend my wife and I made a trip. During the trip we noticed the a/c blower speed slowed down then sped back up. I was surprised when the cruise control turned itself off at least twice on our return trip.

    Monday and Tuesday I heard the chimes again when I made full stops for traffic lights when I was almost home. The message displayed this time was stating the stabilitrack was off. Today it seems to be working.

    Today, Wednesday, a few miles short of my house, I am certain my a/c briefly turned off and on similar to the flicker of lights of a morning. While discussing everything with my wife and mother-in-law, my mother-in-law said she noticed the a/c problem every time she has been in the truck including as soon as I bought it (thanks for telling me).

    IN addition, I do not believe I am getting the kind of mileage I should be getting for the truck. As I said earlier my driving is mostly highway. Of an afternoon I am in traffic but able to move at 65 - 70 mph the entire time. I have installed a Magnaflow exhaust and a Jason bed cover on the truck to try to increase the miles per gallon. Each tank of gas used, I have averaged between 14 and 16.5 mpg. On our recent trip, driving about 73 mph, I averaged 16.6 mpg strictly highway. I feel this is a lot less than I should be getting.

    Years ago I used to be a big Chevy fan until in the 80's GM changed transmission design. Once I had to start having transmission rebuilt I started buying other brands of vehicles. This was the first Chevy I have bought in quite a few years. I hope the electrical problem on the truck is minor. Until these problems started happening we really loved the truck. We liked this truck so much we recently bought a 2011 Chevy Convertible Camero RS (Bumble Bee).

    While I am on here, are there any more rumors about GM building a truck to compete with Ford's Raptor? (A good friend just bought a Raptor and I'm thinking a head to my next vehicle).

    2000 Chevy Silverado. I hit a brick wall and and the air bags didn't go off. GM sent out a investigator to check the computer and after about three weeks they said. i did not hit in a specific area of the truck even though certain parts of the frame was severed off. they said if it was life threatening then i would need a attorney. that was it no appologies case closed .what kind of stuff is that. if youre in a silverado and your in an accident make sure you hit just right. it could cost you your life property damage as well as what ever else may be in the way.

    Electrical Gremlin Removed

    We took our 2009 Chevy Silverado to the dealer yesterday. What they found was high resistance in both battery cables. They replaced both of them under the GM warranty. (We did not have to pay anything). Today I did not experience any of the issues I saw over the last couple of weeks.

    Our experience with Gunn Chevy on IH 35 in San Antonio has been great. The sales staff treated us like professionals. There was no game playing like some dealerships. Other than an oil change, this was the first trip to their service center. Again, we were treated like professionals and explained everything to us. Now if Chevy would just build something to compete with my friends Raptor ...

  • I have a 2000 Chevy Z71 - Alittle history first- the AC compressor has been going out so AC only works partial - it is turned off and on a lot. Battery went out 2 weeks ago and it was replaced. That being said- got in truck 2 days after I replaced the battery and the truck "flipped out". The 4WD light panel started blinking and now does not light up at all. AC getting no power, the gas gauge not working and the light indicator (P R N D panel ) not lighting up, temp gauge not working. Battery warning light stays on. Radio is working, dash backlighting is on, battery volt gauge works and oil gauge works. Speedometer/RPMS gauge works.
    I have done a system check - battery, alternator, and starter no problems - returns no codes. All fuses have been checked. Volt regulator checked. Any suggestions????
  • The other day my wife and I took are dog to the vet it was raining here pretty bad, it was raining all day we were in the vet for about a half hour after the vet we were on our way back to the truck I had started it with the remote start no problem. We got in the truck started backing out of the vet's the door locks started to unlock and lock I thought the dog was hitting the door button, I asked my wife if the dog is touching the button and she told me no. As we started driving home the dash board lights, traction control off came on and I never touched it. We continued home the door locks started going on and off headlights flashing dash board going crazy flashing on and off truck beeping, so I pulled over and checked to see if somthing was loose I could not find anything, so we continued home every time we started to pick up speed it would start doing it again. We got home and got it in the driveway turned it off tried to set the alarm and there was no power at all, I got back in and tried to start it and nothing no power I pushed the brake pedel put it in drive and the power came back on. It has not happened for a few days now does anybody know what causes this problem

    I started experiencing the same problems posted by savvy5000 this weekend while driving in the Texas hill country. The first indication of a problem was stabilitrack needs servicing. Then when appling the brake or using the turn signal, the radio and a/c powered down and eventually turned off. The door locks started cycling, the truck downed shifted and started hesitating at highway speeds. The truck stabilized when I stopped and put it in park. Did not want to turn it off since I was in the middle of nowhere and was afraid it would not start. I started again for home but when I used the turn signal again, the problems returned. It is now at my local dealer and they want to replace the battery cables becuase of high resistance. $600 and I'm afraid that will only be the beginning. Since reading this forum, I wonder if anyone with a truck out of warranty (68K) has had any price adjustment from GM? I'm sure they have a service bulletin on these type of problems.

  • I took it to my local dealership today and they told my that they wanted to replace the battery wires, and told me cause it's past my warranty that I would have to pay full price of $500 plus tax.The first time something happened and go figure my warranty is up. Wow I just think that's a little to much money to let the dealer to charge I think might just change them myself for less then half the price.

    Thanks
  • i had same problem...it coincided with fuel pump replacement.after taking it to a shop ,where they replaced a bunch of sensors,relays,etc etc [all fuel related and electrical] then the problem still existed so they put all my old [and working] parts back in.my bil went from a100.00 when they started to 600 after 3 days and a dozen replacements ...then back to 200 when they put all my old parts back.FINALLY a mobile mechanic happened to come by ,and after 15 minutes he found problem...a loose wire connection from fuel pump wiring to the power source for it....5 days later it was solved.....all over a loose wire connection..IT was a relief because id be driving along fine and then a warning light on dash would appear saying loss of engine power .. my max speed would be 10-15 mph ..sometimes id get lucky by loosening fuel filter and releasing pressure,or removing positive cable overnight to reset computer ...etc etc tried a bunch of things but ...check wiring from fuel pump on top of tank .you can loosen bolts and dropit a few inches for access
  • I have a 2004 Sierra SLT 4WD with 70,000 miles. Bought new. Had to replace driver side auto dim heated outside mirror for $600. Somehow it got chipped and was leaking heating oil. At same time, replaced original battery at dealer. Another $170. Just got it home and noticed the snowflake light switch on the automatic heat/air unit doesn't light anymore. Other buttons are lit: Off, Recirc, Defrost, DeFog. If I tap it, the Defrost light next to it flickers but stays on. The AC snowflake light still doesn't come on. Is this something simple to fix, like a light bulb. I still love the truck, but would like to have the light panel working as intended. Can you advise me on this, someone?
  • My cruise recently quit working. The orange light on the steering wheel still comes on, but the green one on the dash will not. Wondering if it's just a problem with the button, or something more serious?

    Anyone got any advice?
