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.

In October 2015, I was driving on the interstate in a rural area, and accelerated to pass another vehicle. My passing speed was approximately 80 mph. I merged back into the right lane after passing, and let my foot off the gas. Cruise control was not engaged. The car continued at the passing speed, and started to increase in speed. I waited a few seconds to see what would happen before taking evasive action; as there were no other cars on the highway at this point. For 4-5 seconds this continued. I tapped the brake and no change was detected. I then tapped the accelerator pedal; and the speed disengaged. Vehicle was taken to dealer; diagnostic was run and they could not detect a problem. Dealer was of the opinion that this event had something to do with the drive train, they drove the car but were unable to duplicate the problem. This all seemed to indicate that cruise control was on; however I am sure it was not.

Driver had stopped at stop sign on the exit ramp and as she began to accelerate to crossover to appropriate lane the car stalled in the middle of the road, reduced engine light came on, and check stability light lit. This was in a very dangerous location as the side road the driver was located was at the bottom of a hill, so oncoming traffic would not have been able to stop and it would have been a T-bone hit for the driver and head on for the oncoming vehicle. The car slowly (very, very slowly) moved forward enough to finally get across street and to a safe place. Although no accidents or injuries occurred, it was by the grace of god that no traffic was coming over the hill. This had the potential and has the potential of being a deadly problem if it occurs again or if another vehicle has the same issue. Immediately had tow truck pick up car and take to GMC dealership. I am awaiting the results from the dealership. My work requires a lot of travel and now I do not feel safe in this car with this issue (which after research today seems to happen a lot in GMC vehicles. )

The drive shaft is all rusted. I told the dealer about it and they say that it is made out of steel and not to worry. I am still scared of driving it.
