ENGINE, STEERING, SUSPENSION
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 NHTSA review owner complaints and manufacturer technical communications to determine whether this condition presents a broader safety-related defect. Vehicle: 2015 Ram 3500 Laramie 4x4 Engine: 6.7L Cummins Turbo Diesel VIN: [XXX] Approximate repair estimate: $4,000 Dealer diagnosis: timing gear housing-to-engine block/cylinder block gasket oil leak INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(

STEERING
The contact owns a 2015 Ram 3500. While attempting to have an alignment performed, the contact was informed that the steering drag link and the tie rod were both cracked. The failure caused rapid, premature wear on the tire. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 19V021000 (Steering); and believed that the welding that was performed in the recall repair had directly caused the current failure. The vehicle was taken to an authorized dealer, where the technicians diagnosed the vehicle and determined that the previous recall repair made it impossible to perform a proper wheel alignment. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 193,000.

ELECTRICAL SYSTEM
The contact owns a 2015 Ram 3500. The contact stated while driving approximately 70 MPH in the left lane, the check engine warning light illuminated, and the vehicle simultaneously went into LIMP Mode. The contact was able to pull over to the shoulder of the roadway. The contact was able to continue driving, but the vehicle failed to exceed 5 MPH. Upon arriving to the residence, the vehicle was scanned, and it was determined that the turbo charger actuator had failed and needed to be replaced. The contact purchased an aftermarket part and repaired the vehicle. The dealer was not contacted. The contact later became aware that the failure was related to Chrysler Extended Warranty Coverage Number: X99; however, the contact had not received a notification from the manufacturer. The contact requested reimbursement from the manufacturer; however, the reimbursement was denied because the vehicle was not repaired by a dealer. The failure mileage was approximately 50,000.

SERVICE BRAKES, STEERING
humming from the hydroboost pump, actual issue is the high pressure steering line has a nylon tube inside the hose that breaks apart and moves throughout the system. Dodge had one revision of the hose on the early model years but this issue has gone unresolved. I am afraid if i cant get it fixed it may possibly cause the brakes or steering assistance to fail.

SERVICE BRAKES
The output voltage to the Trailer Braking system is low, only 7.5 volts. Other owners have the same problem. From what I understand there is an issue with the computer that keeps the Original Equipment trailer brake controller from delivering full power at speeds below 30 MPH. This is a safety hazard in stop and go driving. There are many complaints about this same problem in the Ram Forumz. Ram should be able to do a software update to fix the problem. One of the posts in the forum stated that Ram has the software update available but will charge a lot of money for it. This is a safety issue and these trucks should be recalled to fix the problem.

STEERING, SUSPENSION
There was a recall forced by the NTSB for a condition where the track bar adjustment nut would come loose and the truck would lose steering. The recall on the track bar was rectified by the dealer by welding the nut on the track bar. Now that the nut has been welded a proper alignment can not be preformed. There is no longer adjustment available due to the welded nut. The only way to properly fix this is to replace the track bar. I have had many communications with ram (stellantis) and they refuse to remedy this as they tell me they have complied with the NTSB’s resolution.

SERVICE BRAKES
At about 3,000 miles I noticed a periodical head light flicker and intermittent radio issues. Shortly after that the truck has presented with periodical brake issues. My front brakes parodically drag and get hot. Typically on one front side or the other. However on [XXX] my wife and I took the truck out for a drive and both front brakes began dragging and heated up. I had to be towed 40+ miles back home. Two of my neighbors can verify I've had issues with the brakes on multiple occasions for several years now. I've had to limp the truck home on several occasions while in town and in Feb. 2025 it put my wife and I in what a consider a dangerous situation by stranding us on the side of the highway. I don't remember any warning lamps coming on but I did a scan after I got the truck back home. B170-15, B210A-16, B222C, B2861-15, P2509 & P2560 were present. I used my scanner to delete the codes and reset the EMC but am a bit hesitant to take the truck out on the road. Note: The truck has experienced a weird and harsh vibration on back of truck as well. I stop, shut engine off - do a walk around but haven't been able to pinpoint anything. Crank engine back up and problem has seemingly resolved itself. I think it's possibly a brake issue as well. At present this truck has less than 11,000 miles on it. Yes, LOL, less than 11,000 miles. Calipers and pads are in excellent functioning order. Fluid is easily pushed back into reservoir with no restrictions and no apparent degradation of flexible lines. I considered the brake fluid might have moisture built up in the system so I had a complete fluid replacement done but problem has persisted.I did read there's a recall on the the HCU/ABS unit and my truck seems to be in that category but haven't received anything from FCA. [XXX] Your attention and assistance would be greatly appreciated. Thank You. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, UNKNOWN OR OTHER
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 NHTSA'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.

ABS Module failed and is not reading rear wheel speed. Shop isolated issue to ABS module, and hydraulic control unit. Four safety components are no longer working as a result: ABS braking, traction control, 4wd, and rear back up sensors. This appears to be a common issue with Rams HD trucks as the parts are on back order causing me to drive my vehicle with no safety features.
