At all periods of stopping and applying brakes and putting vehicle into the park position, the vehicle will lunge forward, approx 4-6 inches. This happens of flat surfaces, inclines, any and all surfaces. It has almost caused numerous front end collisions. This happens every time I apply the brake, then engage vehicles transmission into park. Happens on any and all road surfaces. Vehicle does not lunge when only brake is applied, but when it is shifted into park. As soon as the park is engaged it lunges. Nothing I do can stop the lunge. Very dangerous and I will record video of this for future references if need be,

Vehicle with auto transmission was switched from reverse to drive position on flat surface. When driver moved foot from brake to gas pedal vehicle lurched backward striking pole. The vehicle was also observed lurching forward when reverse lights were on. Dealership replaced tcm control solenoid valve and reprogramed.

First incident I was driving at approximately 60 mph, when I got a check engine light, service stabile track, and the cruise kicked off, the vehicle slowed and started to chug. I pulled over, shut the vehicle off. Checked the oil etc, and restarted, it seemed fine. A couple of weeks later, I was at a stop light when it did the same thing, except this time the vehicle shut off. I have had three more occurances with this and they seem to be getting closer together. Something needs to be done about this as it is a real cause for concern. I have read the forums and many who have the same issue that I have. I do not feel safe in this vehicle, and dread transporting my family in it at this time.

During regular scheduled maintenance, was told that the power steering great needs replacement because it is leaking ($1500). Not covered under warranty. Strangely enough, my 2010 Chevrolet Tahoe had the same problem at 32,000 miles but was covered under bumper to bumper warranty. This is not a coincidence in my opinion.

Between 5 and 7 times the dashboard message would appear with message stating service air bags. Took to dealer on four occasions to fix. Next a dashboard message would appear informing me of engine failure, loss of power.the vehicle would slow down to no more than 20 mph. Pulled over shut engine off and than it would be ok. Next time about 5 days later the message again appeared when my wife was driving with grand kids. The engine slowed down to about 20 mph, while she was blending into traffic on a highway. Had to pull over or be run over by traffic. Took car to dealer for repair. Next the vehicle developed a backlash in drive train, which is noisy. Dealer said G.M had service bulletin on the noise and recommended ( do not repair) noise is typical. Idid not have the noise for first 20,000 miles. Afraid that this is another safety issue that G.M does not want to address. Lost all confidence in vehicle safety. G.M won't buy the vehicle back or give a realistic trade in value for it.

Driving on highway, started up hill at 55 mph in traffic. Following alarms came on: Traction control dashboard symbol; stabilitrack off; engine power reduced; traction control disabled. Vehicle immediately slowed to 40 mph and would not go faster. Online forums indicate this is a throttle body or ECU problem, known to GM at least since 2010. It has been handled on an individual basis depending how much the individual customers complain. I regard this as a safety issue since in highway traffic it could lead to a rearend collision at high speed with consequent loss of vehicle control and loss of lives. Believe GM has used search engine optimization to bury the forum discussions on this, but if you search for Chevy Traverse throttle body defect you can easily find it.
