Unfortunetly my Nitro's tourque coverter has taken a turn for the worst and is vibrating worse than ever. Its been to the shop more than four times which is Delawares lucky number for the lemon law. Last time, today, the manager took some viberation analyzer with him and read vibrations from 0-40, 40-50, and above and compared it to that of a 2008 and said the 2008 has more vibration. However unless he rode right at 43 for a little bit it probably did not even vibrate, and I had to goto work so I didn't ride with him. However his answer to everything is I rode another Nitro and it vibrates too. Anyway a guy at Chrysler corporation pretty much told me this is just how the Nitro rides. That my expectations for an SUV are too high, and to call back if something breaks. I tried to argu that its not normal and he kept saying for an SUV it is. Well I asked why they have TSB's for this so called normal condition and he didn't have an answer. He then told me the dealer who put it my new tourqe converter wasted Chryslers money and that it won't fix it. So anyway long story short is this the point where I need to contact a lawyer? I thought Chrysler would cooperate more. For anyone who has dealt with this, was Chrysler helpful or did you go through your local dealership or have to use an attorney? I wish they would just find a fix for this problem.
