I purchased a 2016 Chevy Trax from this dealership, in November 2019. Plagued with problems. Car had a previous smoker, dealership took a week to rid me of this problem. On-Star wasn't working, they did fix it, took three days. Then squeaky breaks reported, prior to spring break, by wife and myself, as well as, possible back break locking up. They tell us there is no problem. Muffler loose and they can't fix it, even though certified car. Weather stripping coming up on top of car passenger side, they said they can't fix it. i am wondering what: certified means", apparently not much. They had the car from March 10th, until March 17th, to tell us all they couldn't fix and what was wrong. I will use another dealership for service, from now on.
