The experience that soured me was the dealership experience trying to get anything done under warranty. Three different dealerships, three different states.
One such experience was a crooked one; X-wife took TA in for CE light on=smog pump. Dealer printed off a repair quote for $800+ and told her it was not covered under warranty. They also told her driving it that way would damage the engine. At the time we did not have the money, so she left the dealer and brought it home so we could discuss. I looked into it and learned about "Federal Emissions Warranty". The manufacturer was responsible for the cost and repair. I returned to said dealer, chewed some ass, listened to their song and dance, got smog pump replaced on GM's dime.
One such experience was incompetence; transmission mount failed due to oil leak causing excessive movement of driveshaft which led to pinion seal leaking. Dealer performed repair and while replacing pinion seal, over torqued the hell out of the pinion nut. Leaving the dealer the rear diff. was growling like a mofo. I went back, they told me to pound sand, ain't nothing wrong. Did a 800 mile round trip run a couple days later. Over 90% interstate at 65 mph+. The noise was incredible. When arriving at destination and emptying the trunk I discovered stuff was very warm down at the bottom. A 3 D cell mag light was almost too hot to pick up. After the trip the TA went back to the dealer and had the ring/pinion gear set replaced. I asked for the old parts back and kept them in a box for years. They were chewed up bad.
I could go on. But won't. It is dredging up ghosts. It is making me rethink the $500 deposit I have on the '23.....
