3 weeks after owning my Nitro SLT, it would not start - it would when it was hot, it would when it was cold but not when it was warm. It ended up being a bad fuel pump. For those of you who are experiencing the stalling, you may want to have your dealer check into the fuel pump, in case it is related.
At the same visit, I complained of a vibration - the dealership reflashed and rebalanced the tires. The condition is now worse.
At the next visit, they thought the drive shafts were not properly balanced so they flew in a Chrysler technician with his special tool to find out that it was not the problem. They did replace the drive shafts anyway. The dealer proceeded with replacing the rear ring and pinion, that did not fix it, now they have replaced the front differential. After all of this, the Nitro still "shakes" at 30 mph (1200-1500 RPMs - I describe this as the feeling you get when driving on rumble strips) and vibrates at 40 mph (1500 RPM). We have been told to drop into 2nd gear so the RPMs would be brought up. It stops the shaking and vibrating but the motor is now racing because the RPMs are too high. This is what the dealer described to me as the "fix" and that Dodge has no plans to write a program to reflash my Nitro.
I now have an appointment for them to look at it again tomorrow but the bottom line is - Deal with it, Dodge has no plans to change the current program. I guess I'll be checking into my rights under the Lemon Law next.
