Bought the extended warranty 6 years total 120000 km.
Brakes failed at 34000km. Pads and rotors were not machinable at all. All 4 wheels brakes had to be replaced.
Brakes again at 66000km. All the way around, pads and rotors. GM dealer indicated that we did not use the brakes enough. None of the brake work was covered by warranty either time.
Vehicle would not start on many occasions at varying temperatures. If you just wait 15 minutes it will start.
Ball joints upper and lower replaced at 47000km.
4X4 transfer unit replaced at 50000 km.
Ball joints need replacing again at 66000km, pitman arm, lower control / idler arm need replacing. GM won't replace ball joints until.25 inch play in ball joint, hopefully it never lets go while I am driving.
My wife's 1992 Taurus with 220000km is more reliable than our 1998 Jimmy with 66000km.
I was born and raised GM. I have never owned a non GM car. I guess there is a bad apple in every bushel, but this is my last GM.
How does not using the brakes enough cause them to go out? You'd think that not using them would help them to last longer. I think your dealer is full of bull.
Not using the brakes often means the rotors build up rust and they become pitted. The dealer was correct in stating this.
