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.
