General Motors review: 2009 chevy traverse

Took traverse to dealer ship on november 13 2017, after having problem with losing power. On highway causing a drop in speed from 65 to 35. Suddenly. Caussing a car to almost rear end me. Dealership keep traverse overnight. And said that it was trans. Picked traverse up week later on nov 17 2017. They said problem fixed. Drove home and two days later. Problem returned. Called dealership back. They said bring it back they would run more test at my expence. Decided to do some research on my own. And after reading traverseforum.com and edmunds site. It sounds like it is stabilitrac traction control / throttle body problem. All research points to problem. And should be covered under a recall by gm. Since their are 1000 or more complaints on this part.. At least labor should be coverd.
