“Radiator failed on 2003 Dodge RAM 2500 hemi 4x4 at 51,000 miles. Vehicle has a 7/70 drivetrain warranty, however chrysler said that the radiator was not covered. Chrysler had me participate in the repair by having me pay $150. Dealer would not tell me what was wrong with the radiator. I had to call chrysler corporate and find out what was wrong with it. They admitted that it was a manufacturing defect.”

I have reported problem to dealer but they unable to help because no codes are generated by the computer.

“I have a 2003 Dodge RAM 2500 with the cummins diesel engine. With the air conditioning system off, but the ventilation (heat or just cool outside air) on, I have diesel exhaust fumes entering the cab of the vehicle when idling or moving at very slow speeds. The condition goes away with the A/C on or with the vents in the recirculate position - I.e. Not drawing outside air in. The smell and gasses are dangerous for any extended period of time and could cause an accident if I breathe them for a long period of time and then attempt to drive.”
