We have a 2015 Suburban LTZ, transmission went out while driving down the interstate with our whole family in the car, almost causing us to crash. We got the same run around with GM. No help. The dealer I bought it from was just as shady. The dealer and GM were talking behind our backs and telling us two different stories. My suburban had 101,000 miles so warranty was up, Basically we were screwed! A year after a bought the suburban the magnetic air ride failed, paid $1800 to replace that. Now the transmission? I have now put $7000 into a $65,000-70,000 vehicle. I m stuck! Can’t sell it bc I owe more than it’s worth, the value has decreased so much, (I’m assuming bc all of the issues they are having). We fixed the transmission out of pocket but I still don’t want the piece of shit, I’m waiting to see what else go wrong with it! I heard the air conditioning is next...
