Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Fire reported

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.

Dear NHTSA, 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. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The contact was able to pull over to the side of the road, and after opening the hood, the contact noticed an oil leak. The vehicle was towed to Patriot Diesel, where it was diagnosed and determined that the EGR system and fuel system failures had caused catastrophic engine failure, and there was a hole in the engine. The mechanic determined that the engine needed to be replaced. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Numbers: 22V406000 (Fuel System, Diesel) and 19V757000 (Engine and Engine Cooling).

Imediately following z46 recall my vehicle lost all motive power on the interstate. No warning lights etc. Dealer who performed recall took no responsibility and explained my engine has seized. My research has determined this.is common when the recall is not.properly.performed. I have documented evidence proving the recall was not performed. Dealer suggested I contact the manufacturer. Manufacturer has not helped and Dealer takes no responsibility. I've been told to replace the engine is 20 to 30 thousand dollars. This.is aproximately.what is still owed on the vehicle. The BBB and the aohio attorney generals office claim they cannot compel anyone to take responsibility. What am I supposed to do? I am a paying client to eveyone.envolved and now I'm supposed to countinue paying for a vehicle that is totaled. The manufacturer recomended I see another dealer. The next 2 closest dealerships refused to get involved saying it was the original servicing dealers and manufacturers problem and they did not want to be involved. Upon asking.the manufacturer who to take it to they claimed they cannot force there dealers to service a vehicle.

In writing complaint against FCA for not fairness for some VINs with Ecodiesel doesn’t include W68. Following with recall W58 vs W68, my VIN was picked for W58, but never pick for W68 because my VIN is not included. Just complete service for crankshaft throttle failure and spent $2000 for this. I am very disappointed that crankshaft failure recalled do not cover because W68 was not included. I think those W58 for computer update failed to prevent break down due to loose magnetic issue. My VIN is suppose to add recall for W68 because FCA missed this. W58 failed to cover the damages with crankshaft which is mean computer doesn’t solve the problem.

My 2015 Chrysler Ram EcoDiesel 4x4 has a major safety defect that nearly caused a catastrophic accident and has left me traumatized. The vehicle is currently inoperable, sitting in my driveway with a dead battery and what sounds like a thrown rod after breaking down for the second time on the highway. While driving on Highway 101 in California, towing a horse trailer with live horses, the truck suddenly lost power without warning. I was left struggling to control the vehicle and avoid a crash in high-speed traffic. This was one of the most terrifying experiences of my life. Losing engine power with a loaded trailer on a busy highway could easily have resulted in fatalities — not just for me and my animals, but for other drivers on the road. I was horrified and shaken, and I continue to suffer PTSD from the event. This is the second time the vehicle has broken down under dangerous circumstances. The failure was life-threatening, and it is obvious to me that the engine has now suffered catastrophic internal damage (likely a thrown rod). Recall Issues: I had already received a notice of Recall 22V-406, but when I contacted Chrysler, I was told the parts were not available and they would not buy back my truck. The repair was not released yet, leaving me to continue driving a vehicle I already knew had a serious defect. This delay put me, my animals, and the public at unacceptable risk.
