2015 Ram 3500 engine problems

Filed Oct 6, 2026 · Engine, Steering · NC

I own a 2015 Ram 3500 equipped with the 6.7L Cummins diesel engine. An authorized Ram dealership diagnosed an engine oil leak originating from the timing gear housing-to-engine block/cylinder block gasket. The leak has progressed beyond minor seepage. Engine oil is traveling down onto the chassis/track bar area and is leaving drops on the ground. The dealer estimated the repair at approximately $4,000 because of the extensive labor required to access and reseal the timing gear housing. My concern is that an engine oil leak from this sealed housing may worsen over time and could potentially result in significant oil loss, contamination of nearby chassis components, or oil reaching hot engine/exhaust components depending on the path and severity of the leak. FCA/Stellantis has previously issued technical communications concerning oil leakage from the timing gear housing gasket. STAR Online Case [XXX], titled “Oil Leak From The Front Timing Gear Housing Gasket,” instructed dealership technicians to document the leak location, photograph the condition, and measure the breakaway torque of the timing gear housing retaining bolts. FCA also issued later engineering communications involving the rear gear housing/timing case gasket on later Ram 6.7L diesel trucks, including requests to document loose housing bolts and retain removed bolts for engineering analysis. I am submitting this complaint because I believe this may represent a recurring engine oil leakage condition involving the timing gear housing on Ram heavy-duty trucks equipped with the 6.7L Cummins diesel engine. I am requesting that the federal safety agency review owner complaints and manufacturer technical communications to determine whether this condition presents a broader safety-related defect.

I am filing this report to highlight ongoing safety and warranty issues with my 2015 Dodge Ram 3500, which is severely impacted by Recall 67A. This recall was intended to address emissions tampering, involving significant obligations for Stellantis/Cummins Inc. under the emissions extended warranty, termed the "Special Extended Warranty." Since the completion of the recall in January 2024, my vehicle has been inoperable for a total of 148 days due to significant defects. The vehicle has required six service visits to address these issues, with the most recent visit occurring on October 31, 2024, when it was towed back to the dealership. Throughout this process, I have encountered a lack of effective communication from both Cummins and FCA, and my attempts to resolve these issues were largely ignored until I escalated the matter to federal authorities, including Randall Stone from the U.S. DOJ. The ongoing failure to address these defects has not only violated warranty obligations but also poses a risk to safety, as the vehicle remains inoperable. Impact of the Problem: The inability to use my vehicle has caused considerable disruption to my daily life, preventing me from performing essential tasks, including towing a camper and transporting heavy items. This situation has also led to significant emotional distress, given the prolonged nature of the issues and the lack of adequate responses from the manufacturer. Action Requested: I seek the federal safety agency's assistance in investigating these ongoing issues with my vehicle and holding the manufacturer accountable for their failure to uphold warranty obligations and address safety concerns related to emissions defects.

Consistently getting a p00af engine code. Pertains to the turbo boost actuator. Apparently this has become a common problem with many of the ram 6.7l cummins engines. This can lead to poor engine performance and eventually catastrophic engine failure. Currently the repair cost just for the actuator through mopar is $3000. Obviously this is a recurring issue with these trucks, at a substantial cost to the consumer. I began noticing that my engine brake would not engage when descending grades, and then I started getting an intermittent engine light would come on, now it comes on all the time. I had a local parts store look up the engine code for me and it logged a p00af condition. I googled the information and realized that this is a very serious issue that could become a very expensive repair if not addressed in a timely manner. In my opinion, a recall should be issued for this.
