Consumer Description

Driving on the highway and I started to slow down even while pressing the accelerator. Pulled over and turned the car off and then back on. I was able to almost get to an exit but then it completely stopped moving. Turned it off and on again but car would not move. Not a single light turned on until the last time I attempted to move the car. Had it towed to Chevy dealer and transmission was completely out. Had 2 different mechanic places (dealer and private) tell me that it is extremely common once a 2020 suburban hits around 100k miles. That is completely irresponsible of GM to not put something out so that owners can at least have knowledge that there could be a potential problem. No warning signs, no lights on that is an accident waiting to happen and a potential wrongful death lawsuit coming your way if something isn’t put out.
