I've read the TSB for the 3.7L having a whistle noise come from the throttle body, but I was wondering if anyone with a 4.0L had this issue as well?
I've literally just bought my Nitro and I'm taking it in for service because it whistles under acceleration. That and the rear makes a creaking noise when I first drive it, and the front of the roof rack is cracked and warped on the passenger side. Also the exhaust has what I feel is an unacceptable amount of rust for such a new car (was a demo with 6k miles). To say that my nitro isn't making a very good first impression is an understatement. For crying out loud it's a $30,000 car, you'd think they'd have used slightly better materials.
I've driven many dodges before (mostly neons) and have NEVER had any quality issues... go figure?
