The hazard

Issue: On certain chassis-cab trucks equipped with a 6.7 L diesel engine, the engine oil monitoring system may not detect when the engine oil drops below the minimum level. If this happens, the engine bearings could be damaged. This can lead to a connecting rod failure, which could puncture the engine block and create an oil leak. Safety Risk: An engine oil leak can create the risk of a fire. Corrective Action: FCA Canada will contact owners by mail and instruct you to take your truck to a dealer to update the engine calibration software.
