I am submitting this complaint regarding my 2015 Ram 1500 EcoDiesel 3.0L, VIN [XXX]. My vehicle previously received an EGR/emissions-related repair in XXX. The vehicle records also show emissions-related campaigns/repairs, including VB1, V08, and VA7. I am concerned that Ram/Stellantis is not honoring applicable EGR coverage associated with the class action lawsuit XXX v. FCA US LLC, Civil Action No.XXX, in the [XXX]. This case concerns alleged defects involving EGR coolers in 2014–2019 Ram 1500 EcoDiesel trucks. The court-approved settlement provides coverage relating to the EGR cooler issue. I contacted Ram/Stellantis and the dealership and requested that they review my VIN and the applicable recall and extended warranty information. I was told that the applicable coverage was not showing or was not being honored. I was also given manufacturer case number XXX. I am requesting that the federal safety agency review whether my VIN is covered by the applicable EGR recall, warranty extension, or court-approved settlement and whether my previous January 2023 EGR repair affects eligibility for later applicable coverage. My vehicle currently has approximately 168,000 miles. I can provide repair orders, recall documentation, dealership communications, and other supporting records. I respectfully request that the federal safety agency document this complaint and investigate whether Stellantis/Ram is properly complying with applicable recall and extended-coverage requirements.

Exhaust bolts broken. Exhaust leak and loud ticking noise and smell

Filed Jul 7, 2026 · Electrical, Engine · AR · fire

On July 2nd, I was actively driving my 2015 Ram 1500 equipped with the 5.7L Hemi V8 gas engine. The vehicle is completely factory-stock with zero aftermarket electronics, wiring modifications, or accessories. While operating the truck, the dashboard instrument cluster suddenly began flickering wildly, indicating a severe voltage drop or electrical system failure. Immediately following the flickering, a catastrophic fire erupted inside the cabin, originating directly underneath the dashboard on the passenger's side. The fire department responded to extinguish the flames. The engine bay was unaffected by fluid leaks, and the fire originated strictly within the factory dashboard electrical wiring harness/modules. The vehicle is a total loss.

While driving on the highway with my entire family in the vehicle, truck lost power without warning and what it seems it went into a limp mode. This created an incredibly hazardous situation, exposing my family and the drivers around us to an imminent risk of a high-speed collision. Thankfully, nothing happened and no one was hurt. Upon restarting the vehicle, the check engine light illuminated, and power was drastically reduced, capping our speed at approximately 40 mph. I brought the truck to St Charles's dealership for diagnosis. Service department has informed me that the root cause of this catastrophic failure was the crankshaft tone wheel. Furthermore, I was informed that this specific issue was an unaddressed/unfixed defect on my vehicle by Stellantis. What I learned is that the fix for a broken tone wheel required dropping the transmission to physically press a brand-new tone wheel onto the crankshaft. Because this was incredibly expensive and time-consuming, Chrysler rolled out a recall remedy consisting of a Powertrain Control Module (PCM) software flash.This should be unacceptable for trucks that cost $70,000 or any vehicle. Imagine that software failed what would have happened and yet we had no idea about this.

I am contacting you regarding an active service campaign for my vehicle involving the crankshaft position sensor and tone ring. I would like to arrange for this campaign to be completed as soon as possible. I was told by one dealership that my vin doesn't fall under this campaign. The Campaign is noted for the years of vehicle and my Truck stopped mid-drive in traffic abruptly. I feel this could have been a safety concern. When code ran and light on dash it says crank shaft position sensor. Vehicle Information: 2015/Ram 1500/EcoDiesel 3.0 VIN: [XXX] Current Mileage: 192446 I understand this service campaign addresses potential issues related to the crankshaft position sensor and tone ring, which may affect vehicle performance and reliability. I am requesting that the inspection and all applicable repairs or replacements associated with this campaign be performed at no cost as outlined by the manufacturer. Please contact me with the earliest available appointment date and any additional information or documentation needed prior to service. You may reach me at [XXX] or [XXX] Thank you for your prompt attention to this matter. I look forward to your response.

There is a known issue about exhaust manifolds for my year model truck. A ram technician said in 2019 mopar created a new exhaust manifold for my truck that would be less likely to create soot buildup and warping in the exhaust manifold. In 2021 my EGR was replaced because of a recall but now my exhaust manifold has failed and needs to be replaced out of pocket even though it’s been a known issue and there was a remedy already made to alleviate the issue. Now because of soot buildup my throttle is limited until I have it fixed. But driving to a dealership is too far to be diagnosed as there has been cases of fires occurring when this issue occurs.

There is a recall for Ram 1500 manufactured between January 2015-September 2015 regarding failed power steering. My truck was manufactured February 2015 and was not on the list of specific Ram 1500s to have this recall done. I was with my kids getting an oil change on the truck. When I was leaving the maintenance bay my power steering suddenly failed and left us stranded to get towed. Chrysler stated that there was certain conditions that led for certain models to have recalls for this part, but not my truck. They could not give me a clear reason why mine was not included on the list.
