low coolant sensor twice (have to remove battery for access). leather seperating from side air bag cover 3 times. battery leak around positive terminal (what a pain to remove). that weird a/c noise at WOT. a clunk sound when backing out of my driveway, dealer can't duplicate.

 

On your clunking when you back up, I've heard that being linked to either the three braces around the top side of the engine area or the aluminum cradle under the engine. The fix for the top side is to tighten the hell out of them. Have you removed them before for some reason? The bottom cradle requires thread locker saturated at each bolt on the entire carrage. Seems like an odd fix but it is what it is.. lol There is a TSB out on te aluminum cradle and should be somewhere in this forum. I'll see if I can hunt it down for ya..

Here is that link....

 

Thanks for the info, I'll have it checked out while it's on the lift Saturday.

 

Not a problem, let us know what you find...

 

I have to say, I haven't experienced any of those problems yet, but then again mine is still sort of new. I change te oil regularly, about twice as much as the dealer recomends, as well as the tranny fluid and filter. when i start my car cold, it makes this insane hissing noise for like, maybe 30-40 seconds, then as it starts to heat up it goes away, but I know what that is so i'm not concerned, its the aircharger, that thing is noisy as ****. lol, I think I actually like the sound though.
