Had a squeak/popping noise from the front end. 2nd time in the dealership for the same thing, they couldn't diagnose the first time. 2nd time I took the service guy for a ride and he finally heard it. He thought it was suspension. He stated he put an electronic ear and located the noise to be a loose bolt under the front left radiator corner(there's a big rubber bushing on the frame). To tighten that bolt down was $200 not covered under warranty. They believe it was due to body work from an accident? The vehicle has never been in one though. Clean carfax and I've owned it since 1.8k miles and now has 17k miles. They say the clear coat looks funny on the radiator support which I have kept detailed. Funny thing is my buddys truck which was an 06 was making the exact same noise before he traded it in. Btw, my factory warranty is through march 2010. It wasn't titled until 3/07. Any thoughts/arguments I could make to have it be warrantied?
