Jason, sounds like you have had good luck at Pioneer. I am going to try them. Actually, my warranty covers about everything. It has a short list of things not covered. If I drive over a sizable bump, such as a rounded curb, forward or backward, the noise is very loud (clunk). Also experience a loud noise when making hard right turns at slow speeds, like when pulling into a parking spot, with or without brake applied. Sort of a groaning noise. Also, loud noise after going from reverse to forward. Sometimes I wonder if last problem is a result of brake recalibration during reverse (old cars used to self-adjust in reverse). I also have this annoying wha-wha noise while driving. No shaking, steers straight, just an irritating resonance adding a lot of cabin noise. Have new front brakes and rotors turned. Previous owner got a four wheel alignment.
