Short answer, No not yet. Had it for over a year now and have only 4600 miles on it. I have taken only two 1500 mile trips with it and the different composition of the pavement makes a huge difference. If my hearing was still good I would get the new tires tomorrow. Now if I can only stop OnStar from sending me to a dealer for an engine and transmission diagnostic check every 3 weeks or so, only to be told I needed a software update. This started shortly after my first service and oil change early summer. Geez!
