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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

There are times when the truck will not start. It is generally when you have driven a short distance or made several stops. When cold the engine will fire right up. After a couple short trips, when you attempt to start the vehicle upon turning the key the dash will go dead. The engine will not turn over. Wait about 10-15 minutes and vehicle will start. Mechanic checks have ruled out battery, starter and solenoid and a short in the system. We have replaced all the relays. May be a passlock issue, but dealer denies history or defect, but a simple google search shows extensive reference to the issue on multiple Chevy models.

Failure of brake light switch. This is the second failure. This switch was replaced on 05/02/2013. These failures could cause a rear end crash due to no brake lights.

On February 14, 2012 I was driving on a clean, dry, straight, and level road at 35mph. I was not accelerating, braking, or cornering. The alarm bell rang and the dash board display indicated "traction fault, reduced power, service stability system". the vehicle dramatically reduced it's engine power to the point it could not be safely operated in traffic. It was impossible to accelerate with traffic, merge, or make a left turn. I was about 3 miles from the dealer. I drove to the dealer to have it looked at right away. They told me I had no appointment so they would not look at it. I got the next available appointment two days later. The vehicle was not driven from the time of the alarm until the time of the appointment. On February 16th I took the vehicle to the dealer and it operated at full power. There were no lights or alarms. The dealer said the computer had a history of something but did not retain the details. They said General Motors warranty policy would not allow them to repair the vehicle without a specific trouble code that would allow them to minimize the warranty expense. I informed them that they made me leave two days prior when it was operating under reduced power and showing alarm details in the dash display. They should have diagnosed and/or fixed it then. It is unacceptable that the vehicle creates a safety issue by reducing engine power when there is nothing wrong. It is equally unacceptable that an issue serious enough to cause reduced engine power is not retained by the computer so it can be diagnosed and repaired. This is likely to cause a vehicle accident where someone could be injured or worse. They did tell me that if I paid for the extra cost onstar system it could have given the details on the problem. If the vehicle requires onstar to safely operate, it needs to be a free service.
