We used our car for work travelling, so we put quite a bit of miles on our Traverse, but luckily we bought extended warranty, because at about 80,000 miles (mostly freeway) we got a low end knock. and about that same time the transmission started slipping. Chevrolet was great about fixing it. We got a brand new motor in our car, and they rebuilt the transmission. I like the car, but I probably wouldn't buy it again.
