2012 Buick Enclave Transmission and drivetrain Problems

“I have looked up my vehicle information through GM. I can see where they had the vehicle in a shop in ny to look at it. Unknowingly I bought a vehicle with a huge list of issues! First of all, the torque converter was going out on my vehicle when I purchased it for a dealer. Second, the transmissions on the enclaves, acadias, traverses and terrains are junk! I take great care of my vehicles and have never had a transmission fail on me at 100,000 miles! When GM has this vehicle in ny they should had replaced the transmission and the torque converter when it was still under warranty! …”

“I stopped at a red light on a hill and when I took my foot off the brake the vehicle started to roll backwards.it would roll backward when it was in drive. I almost hit the car behind me.

When I was going uphill in drive and stopped and took my foot off the brake it would roll backward until I put my foot on the brake and as soon as I came to a stop and took my foot off the brake in would roll backwards again. …”

“Multiple instances of the transmission slipping into a neutral-type-state while attempting to merge onto/into highway speeds. This has occurred over 20 times in the last 1.5 years. Dealership took car on multiple occasions and was able to replicate it 1x. Their corrective measure was to re-download transmission software. This did not fix the issue. This is an intermittent problem that poses a significant safety risk, as the slippage can last anywhere from 1 to 3 seconds.”
