Gas Recirculation Valve (egr Valve) problems of the 2010 Chevrolet Traverse

Several malfunction indicator warning lights and messages continue to appear on the driver console under certain driving conditions. They warn "service stabilitrak" ; "service traction control" ; and, "engine power is reduced" these malfunction alert are accompanied by a severe deceleration of the vehicle and no response or very modest response when the accelerator is depressed. This issue has presented itself four (4) separate times in 2016 and 2017 while the vehicle was being driven on highways (3 times at speeds of 60 mph) and always when the temperature has been near or below freezing (32 degrees). Gm has notified me of this issue impacting cars of the same year, make and model. However, the vehicle on board computer (obc) clears after the 3rd restart (according to the dealership) and proof of the error via the obc is wiped out (only leaving me with video and pictures, which GMC will not honor in its repair protocol). As stated, this reoccurring issue is being experienced at high speeds on busy highways and the car will quickly throttle down to speeds of 30-40 mph -- which is a very dangerous situation in a highway environment (like the 495 beltway in washington, DC). I truly fear for my safety in driving this vehicle and GMC is complacent in having me prove through the obc that this is happening, and then having a dealership recreate the issue. There a hundreds of references to this issue as I searched the internet for answers long before GMC reached out to me. GMC is playing games with consumers and advising that this issue dows not pose to safety hazard. My experiences in this vehicle are proof that their claims are false. Please investigate this issue --- contact me --- gm's protocol is getting in the way of addressing dangerous vehicle issues.

At approximately 90,000 miles the check engine light came on and after it was evaluated at the Chevrolet dealership I was notified the timing chain went out and I had a gmpp extended warranty and the Chevrolet dealership repaired the timing chain. 6,000 miles later the check engine light appeared by flashing repeatedly and the engine seized and the dealership investigated and stated the catalytic converter disintegrated and pieces of the catalytic converter was sucked into the engine. They stated the engine had to be replaced. They claimed to contact gm and gm said they were aware of the issue but it was not considered a recall. Gm offered to pay for $8,000 of the $10,000 total engine replacement. I was only offered a 12,000 mile warranty for the new engine. Now with 50,000 miles on the new engine the timing chain has gone out once again. I do not believe the issue with timing chains was resolved in 2010 with the new ecm; this issue continues as noted and seen with several complaints on this site.

Tl the contact owns a 2010 Chevrolet Traverse. While driving above 50 mph in temperatures below 40 degrees, the "service stabilitrack, engine powering slow" message would display and the speed would suddenly reduce to approximately 30 mph. The failure was not diagnosed or repaired. The manufacturer and local dealer (hubler Chevrolet in rushville, in) were notified and did not assist. The VIN was invalid. The failure mileage was 60,000.
