| Diesel Fuel System problems |
The fuel return assembly on the 3. 0l turbo diesel engine leaks fuel due to the failure of the clamps on the hoses and the o-ring at the return assembly connection point. This has been acknowledged by daimler benz and Chrysler as a technical service bulletin on other vehicles with the same powertrain and could result in a fire but has not been recalled.
The vehicle tends to lag or stall during normal driving times. If you accelerate then let off the gas, then try to accelerate again, the car does not respond. It is like there is a dead pedal. It takes roughly a second for the car to respond, which isn't that long until you consider at normal in-town speeds, you can go almost 100 feet in a second. Just enough time to get plowed in to!.
