I have an extended warranty and I took my wagon in for service a couple weeks ago for a creaking/rattle coming from the back. They said it was my aftermarket exhaust/hangers. I was like no way. Since it sounded like it was coming from the inside of my car. They changed my oil (free lifetime oil changes) and said that they adjusted the exhaust which should help the creaking. I drove away and still the creak was there. I called them and they told me it was probably still the exhaust and that I should come back on my next oil change and they'd check it out again.
Yesterday, I open my hatch and the passenger side shock pops out at the top. I check it out and the threads are stripped and it looks like I'll need a new hatch. I take it to the dealership and they agree that I'll need a new hatch since the shock thread into the hatch itself and that was stripped. They say the extended warrranty doesn't cover it.
I think it's their fault for misdiagnosing the problem in the first place. If they would have tried to solve the problem instead of blaming it on the exhaust it wouldn't have gotten this bad.
I think I'm gonna have to take it to a body shop and have them weld the hole and rethread. But I'm getting a refund on whatever is left of my extended warranty. It blows. Everytime I take the car in for something it isn't covered.
Sorry had to vent.
