Having access to other owners has helped me so much! I was wondering if other RT owners specifically.This is a BIG one that terrifies me! I have a remote start on mine and i have noticed that when the engine starts after it has been sitting overnight the engine sounds like a a bucket of bolts and sometimes sounds like a diesel! I have read other forums and a similar complaint was listed. The end result was that a cylinder was scored and the block had to be replaced!Im still under warantee but for what would i want a vehicle that has had a major engine defect? There are other issues as well. The driverside footwell heat or lack thereof, there is a selection on the heating knob that says feet only but the air seems to come out every other port so that i have to close all the dashboard vents.Also on specifically one right hand turn that i take to work after the turn there is a one second delay from the gas pedal for the vehical to go.This too was observed on another site as a problem.And there are the other obvious ones roof racks lifting noise in the suspension that ofcourse the dealer can not duplicate seems to be a all too commom catch phrase for Dealerships. Any help with the engine prob would be great my Nitro was built between Jan 07 and april 07.
