Ram truck engine fires have prompted a recall of more than 32,000 model year 2019—2020 Ram 3500, 4500 and 5500 chassis cab trucks with Cummins 6.7-L engines.
The engine calibration software fails to warn drivers of low oil levels caused by oil leaks from connecting rod failures.
Low oil levels cause insufficient lubrication and deterioration of main bearings, engine damage, punctures to engine blocks and vehicle fires.
If Ram truck drivers hear strange engine noises, connecting rod failure may be imminent.
Fiat Chrysler is aware of at least four customer assistance records, 56 warranty claims and 56 field reports from August 2019 to March 2021.
Recall notices will be mailed July 30. Ram dealerships will update the engine calibration software.
