Hatch rattle I don't have so can't help you there BUT, if your headlights are beginning to get cataracts & the car is still under warranty take it to the nearest Crossfire dealer (not all Chrysler dealers are Xfire dealers!) & tell him you need them replaced.
I would imagine (help me out here members!) that the pump would void the warranty. Frankly, IMO, I'd keep taking it back to the dealer & getting another Bosch installed until the warranty is history. No sense spending my bucks yet! Then, if (when) the pump decides to play dead again buy the Johnson (why does that sound so wrong?)
So far, no pump issues with mine yet.......26K & counting. I'm waiting for the day though.......
