This has been so frustrating, but I purchased the vehicle used with 39k miles on it. It has been 1 1/2 months and I have put 1500 miles on it and everything was running extremely smoothly. I get in the vehicle after work and turn it on and I noticed a slight vibration in the engine when idle. that I could feel in the steering wheel. I did not think too much of it initially but as I began driving it more over the next few days I just couldn't ignore it any longer. I took it into the Chrysler dealership and they had it for a week and FINALLY called me back in only to tell me it needed a TCM update..I take it and drive it home and the vibrations have gotten much worse during idle, during acceleration and in reverse. I know it is in the engine because it gets increasingly worse as the engine warms up and I am in drive but stopped. So much so that the plastic in the interior is vibrating so much it makes an extremely annoying clicking noise. I can't stand it, hopefully some of you folks can give me some suggestions! Please help, the dealership has told me that unless it pops a code there is absolutely nothing they can do which I somewhat agree with but there are components not attached to sensors in the powertrain and if something goes wrong with that how the **** am I supposed to have it covered under warranty coverage??
