Going to get my 2nd muffler looked at. Sounds like there is an exhaust leak and the muffler make a lot of noise when you get on the pedal. Problem is that Ive moded enoguh to where they will notice. We shall see if they are mod freindly or not.

 

I have had my Jeep in to the dealer for death wobble, broken heat shields, some whine from the undercarriage that goes away once warmed up, leaking hardtop panels and dry start. All warranty work and they didn't fix a thing! They told me they didn't hear or find anything. This is a bone stock 09 unlimited with 46,000 miles and have never been off-road. The first time I went to this dealer they didn't screw the rear oil drain plug in back in the rear diff and 2 hours away It was all over the road. Luckily there was no damage because I pulled over because all the blue smoke coming off my exhaust. The 2nd time I went in they still couldn't find the heat shield rattle. I took the tech for a ride and he laughed said " wow how did they not hear that". Then took it back did some magic bends and said come back if it keeps doing it. OH THANKS what a joke this whole experience is just frustrating beyond belief. Oh they did manage to find leaking transmission lines though go figure I didn't even take it in for that. I have an extended warranty and the thing is worth nothing. Good luck you will need it.
