problem #61

Takata recall on my vehicle - why is taking so long to remedy this recall? I also have a few other issues I want to mention. I bought my Tahoe in July 2016, my dash is cracking on the driver's side and from what I've read, this is very common and GM is ignoring the issue. My vehicle also started taking off on its own, took extra pressure to stop & RPM would fluctuate sporadically. After contacting a dealer, I was told there was campaign to replace the throttle body sensor but it had expired while the previous owner had possession and was told I'd have to pay for the repair and would possibly have to replace the throttle body. After replacing the sensor, my vehicle's RPM still fluctuates upon stopping and idle is rough. Very upset Chevrolet customer now.

My 2008 Chevy Tahoe ltz electrical system would go through a series of phases either when I try to start it up during a cold day or when I am on the highway. This leads to my vehicle either not starting or while driving not being able to maintain speed because the transmission begin to slip. It can also die without warning and the "check engine light" would come on for a while and can disappear after starting up again. I have taken my vehicle to the same service adviser/manager each time I experience this problem and also called gmac to get them involved to be told that they can not duplicate this problem. When ever the codes are pulled, there could be at least 7 at a time. I called gmac went I experienced this for the fourth time and my case number was 71-1326091502 issued on 07/02/2014. Today my case number is 8-2552333596 which was issued on 11/30/2016. I had many other number in between and custom service personnel (gmac) attempt to assist me and the results in the past has been the same each time. However, my vehicle continue to be unsafe. I feel that no one really care but are going through the phases to say that they have done all they can do. My vehicle started to give me this problem at about 107,000 miles, right after my 100,000 mile bumper-to-bumper warranty expired which cost about $2400. My vehicle also have a total of about nine plus (problem more) months in the shop at the Chevrolet dealership over time where I purchased this vehicle with no results at the end of each trip but it was taken back for the same thing each time. I feel as if every one is just coving themselves by mouth work whether than by actions. All I know is that this vehicle seem to be a "lemon" and no one has the courage to say so. My vehicle is at al serra Chevrolet North, Colorado springs, co. 80920. There # is (719) 867 2990. My # is 719-282 9771. Thanks for your time. Rev.

The door actuators went out on my car. The vehicle is all factory settings. I believe it is a manufacturer issue or electrical. Doors not lock using key fob or power locks button. Have to manually lock.

I have a 2008 Chevy Tahoe ltz and the door locks just quit working one day. On all 4 doors!! the key fob will not lock or unlock the doors nor will the lock or unlock button in the car will work. I feel this is a major safety concern. What if you are stopped at a red light with no way to lock your doors and someone jumps in your car with you with a gun! I have two small children and this is a major concern for me! please issue a recall for the door locks.

Dash has 2 large cracks above the instrument panel and another one at the passenger airbag. During operation, stabilitrak light comes on, all gauges go to zero, doors begin locking/unlocking, vehicle loses power, radio goes out and clock resets, lights flash, and battery dies as soon as ignition is turned off. Numerous calls to GM and visits to dealership. No fix as of yet. This has been going on for years. Now odometer has reset to zero.

I have had my 2008 Chevy Tahoe to the dealers 4 times due to stabilatrack light comes on, then my windows continue to click brake lights quit working windows won't roll up or down and sometimes the vehicle will not start. On the third time they said it was the mega fuse and replaced it. Everything seemed fixed. I parked the car in the garage and pulled it out approximately 7 months later to get to my shelves and when I went to pull it back in the same situation happened again. I have not taken back to the dealer yet due to the extreme costs that I have continued to pay the previous time for it not to be fixed.. it effects the complete electrical system to the vehicle.

Passenger side door lock started having problems. Would work occasionally. Now, it won't work at all. Has to be manually pulled up to unlock and pushed down to lock. I noticed over 450 complaints from others about the actuators going out on theirs too. Seems to be a problem.

There are numerous cracks in the dashboard around the airbag. I am worried if the air bag will prematurely deploy, or will not be able to deploy as designed with the cracks. My vehicle is a 2008 Tahoe ltz. There are countless people with the same issue, with the crack in the same place. I have no idea what is going on with the electrically system and what the cracks might be doing.

The contact owns a 2008 Chevrolet Tahoe. The contact stated that after taking the vehicle to the dealer for NHTSA campaign number: 10V240000, (electrical system), the contact was informed that the heated washer module would be permanently disabled and removed from the vehicle. The contact indicated that by removing the heated washer fluid module from the vehicle, he would be unable to remove ice from the windshield during icy weather conditions. The heated washer module was an added expense when the vehicle was purchased. The dealer confirmed that they would not honor the recall repair until they revised the vehicle so that no one could install any type of heated washer modules in the vehicle. The contact requested that the dealer replace the module with a NHTSA approved replacement module but the dealer refused. The contact had not experienced a failure.

I own a 2008 Chevrolet Tahoe 4X4, I purchased it with 80000 miles on it. When I start the car or I am driving all my gauges on my instrument cluster pass beyond the maximum level, even my speedometer sometimes I will be going 40mph but it is marking 80mph. My temperature gauge, my battery gauge, my fuel indicator gauge, even my oil pressure gauge stopped working. The worst part is that my prndl and info center also disappear while I am driving and they re- sometimes after few minutes sometimes for days. The dealer said they have no fix for this, other mechanics said that GM has this issue on most of their trucks and SUVS. I think this issue is very unsafe for drivers especially when all your gauges stop working or work improperly or disappear from your screen, I believe this can be dangerous to drivers as well as other people on the road and GM should find a fix for it. Thank you

Vehicle won't start, dashboard lights all activated randomly, battery not problem, all electrical not working, windshield wipers randomly activated. Vehicle towed to dealership. This is the second time this has happened in 2 months. Last time, battery was jumped and car worked for 2 months. Battery checked 2 different times after, battery is good. Had doorlock problems 5 times since purchase of this vehicle in 2008. Covered under warranty first 4 times, and reimbursed on 5th time. This vehicle has had multiple electrical, sensor problems since purchase. I have never had this many problems with Chevy before. Reading other comments, this seems to be an issue for others as well. Is there a recall for this problem" doesn't seem like other customers have received satisfaction with their issues either. What is Chevy doing to resolve" vehicle is at Chevy dealer now, awaiting response. If this was to occur while driving and all electrical shut off, this would be an accident waiting to happen.

Tahoe 8-cyl

A few years ago all three door locks went at the same time on my 2008 Tahoe. I told my dealer this seems very unusual. Asked if there is a recall and he shrugged his shoulders. I am not sure of the exact date other than to tell you it was a few years ago. A few months ago left blinker wont work. Took to dealer again. Said to bring it back as they needed more time to work on it and think I needed an entire new fuse box. Saturday Oct. 5, 2013 headlights came on while parked in parking lot. Next day it was totally dead. Tried charging it and headlights came on and would not shut off. Had to disconnect fuses and battery. Weird messages keep popping up on dashboard such as check tire pressure. It will say rear but actually it is the front. Sometimes it isn't any tire that is low. Called Chevy customer service and asked why there is no recall and they said it is your responsibility to do so. I researched and found 454 messages from people who have the same electrical problems. Chevy said to contact you.
