Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I bought my 2008 Chevrolet Tahoe brand new. People laugh at me because I've always dealt with the dealership on everything including all oil changes. Now I'm being told that I have lifter and cam problems. I complained about the engine light being on 5 months prior to be told this. I was informed that the check engine light was on because of the tps sticking. I'm a single mother of 2. I purchased a new vehicle not to have these kind of problems especially since I've always taken my truck to the dealership. I cant afford a new engine, my truck is parked and I have to get rides to work from co-workers. I cant sleep nor work.

We had this same recurring problem with this Tahoe for the last 10K miles. Sometimes when driving at higher speed or just idling, it will display a "reduced engine power" and you will loose all power. Engine is still running and lights and radio will work, but you get no power when pressing the gas. Its scary because it happens so suddenly with out any warning. We have spend a couple of thousand dollars trying to trouble shoot this but it hasn't been solved..

While driving vehicle completely stalls no electrical not even hazard lights. I was driving and radio started to static and then car stalled was not able to turn on hazards making it very dangerous as other vehicles were not able to see that I was stalled and got very close to hitting my truck had to call for help as I was sitting in intersection had no way of telling them I was unable to move had to open my doors to call attention to drivers. A day before I noticed that problem began when I parked vehicle and ignition key turned off all electricity will quickly shut off including radio. When at a normal time radio would stay on until door opened. This incident has happen to me 3 times already. I have had full body throttle replaced, battery and ground cables replaced and still not fixed vehicle also shakes alot at times when stopped at intersection.

First problem was the vehicle would not crank. The vehicle had to be jumped off and then it cranked quickly. While driving the vehicle, the window control, speakers and heater would go in/ out of operation. The speakers in all four doors would go out then come back on at different times. Sometimes they would work all at once, other times one, two or even three may come on and off. The heater would come on blowing some times then cuts off again and again. The heater blower would also blow at one speed then blow at another speed without anyone changing the settings. The window controls will make the heater blow stronger, then when the window control is released it will cut the heater off. The rear passenger window controls will not work at all. The rear passengers also can not get out of the vehicle. The vehicle has to be open from the outside for individuals sitting in the second row seats. The only control that will work the rear passenger windows is the driver side control. The vehicle also has a light smoke smell coming from the vents. The passenger side door in the front will open for the passenger sometimes then at other times someone will have to open the door from the outside. The vehicle will not crank back up after been cut off, it always has to be jumped off. The battery is drained everytime the vehicle is sitting down and not being operated. The vehicle was taken to the dealership numerous times without being fixed. GM corporation was called and I was informed a recall was on some vehicles but not others. I was told that my vehicle was not listed as one thou. The dealership checked my vehicle and informed me that my vehicle didn't have any issues but then on a second request they informed me that my vehicle had a bad battery and was having firing trouble. They also informed me that I was not covered by my warranty.

Heard a ticking sound coming from engine, sounded like an exhaust leak. Took in for inspection was advised that there was a broken bolt on exhaust manifold in the rear. Was advised it was not covered under warranty or extended warranty as it fell under "exhaust" and "fastener" components that are not covered. After searching the internet, I have found that this is a very common issue. This is a fire hazard and will cause me to fail emissions when I am due, which also violates the epa laws. I live in Arizona where we do not have weather conditions that lead to rust issues. How can this be possible with such a large problem??

Check engine light began flashing, check stabilitrak light came on, engine sputtered. This was first of 4 incidents from oil consumption issue GM has with this engine. They didn't recall the engine, but had a protocol - a series of bandaids that shops used to repair or prolong. Ultimate step is engine rebuild/replacement, which GM did under warranty for those "in the know." My dealership in small town hamilton, oh, rose Chevrolet, was dropped by GM and is now independent. Neither rose or GM informed me of this ongoing problem. After spending more than $9-- out of my own pocket, the car now needs pistons and rings, for another $3000. Again, GM knew of this issue and didn't inform me of it. Had I know about it, and the magnitude, I would have insisted on repair or replacement while under warranty. I'm a sales rep and drive a lot. The car now has 146,000 miles and I have a case number with GM. They should pay for the repair, reimburse me for my out of pocket and/or repurchase the vehicle from me.
