Here's another on going issue that GM fail to recognize as a defect. I'm upset that a company as large as GM failed to claim responsibility for this problem vehicle. I enjoy the ride but it's been costly and I refuse to purchase another Buick until the company admits its faults. The 2004 Rainier is a piece of garbage and a death trap waiting yet to happen. The rear suspension had to be replaced, the wiring harness failed, the power seats fails to retract and AC works when it wants to. Oh I forgot to mention that the rear axles jumps and pops when it wants as well. I've never had this many problems out of any vehicle I've owned.
