The vehicle was driving down the highway at highway speed when it began to shut down. This put myself & other drivers at serious risk as I had to navigate several lanes of traffic with a dead vehicle. When I took it to the dealer, the dealer stated that the vehicle crankshaft position magnetic tone sensor had broken off and was no longer sending the tones to the crank shaft position sensor. The vehicle has a 66A recall on it where it mentions a 73A recall which states for certain vehicles the tone wheel can be replaced. But for some reason our vehicle and vin number is not included. The 66A recall makes a statement about having a software update but we were never given an information about this recall prior to having this issue.

While driving my 2016 RAM 1500 Eco diesel, the vehicle suddenly lost power and would not accelerate beyond 40 mph. The malfunction occurred while driving under normal road conditions and created a safety concern because the truck was unable to maintain normal traffic speed. Prior to failure, a warning light appeared on the dashboard related to emissions/exhaust system. The truck entered into a reduce power/limp mode and became difficult to operate in traffic. The truck has been at the Folsom Lake Dodge dealership since March 22, 2026 awaiting a replacement part related to a recall/manufacturer issue. I was informed the part may be available around May 22, 2026.

My 2016 RAM 1500 has had an issue with the Anti-lock Brakes since August 2025 that is under the manufacturer extended warranty. I am the original owner. The ABS module and other sensors have been replaced and the problem persist. In the last few weeks, the traction control light energizes intermittently (flashes) and the engine loses power-does not stall out, but does not accelerate. The light goes out and normal operations resume. A few seconds after the light extinguishes, the Service Anti-Lock Brake warning comes on. If I have my family in the truck and enter a highway and loose power, I could be at fault for causing a wreck and injury my family. As a professional engineer, I would like to have this concern investigated before someone loses their life or cause injury to someone. The local dealership replaced the part after 4 months on back order but the problem did not go away. They then replaced other parts and the problem persists. Another ABS module is on order with a 6 month backlog. I feel unsafe but need my truck for work and family! How do I get this evaluated properly as the dealer does think it is happening!

Within 24 hours of buying the vehicle back in February, the truck has not run red Lightning bulbs, electronic throttle control system Lights all started coming on that system was replaced by a certified mechanic. The system then did it again, literally, 1 day later. Now I'm not certain about the new part, which has been discontinued. It's some sort of pigtail off of that. And again the wiring pigtail or whatever it is called. I am uncertain is defective in has been discontinued. I'm into the truck for over $10000, including the purchase price. It has not run 1 day since But after the incident, my mechanic did the car fax on it. The odometer had been rolled back over 100000 miles or replaced whatever the situation, the car facts did not match up with the actual truck information that was sold to me contacted the individual and sold me the truck. He has ghost meat, will not return. Calls will not give me back. The money will not even answer my calls. Any longer longer only through the national highway transportation safety association did I find out that this could be defective parts possibly covered by the manufacturer. So again , i'm not sure where I stand on this uncertain i have contacted several state and federal government agencies. That's how I ended up here, trying to go through the process of getting this taken care of but I got the Attorney General national highway, safety transportation board involved along with the state police, I guess here in Massachusetts have a division for this so. I'm filling out the form and doing what i'm supposed to trying to get myself reimbursed , or at least this truck fixed , because again pots have been discontinued and nobody including dodge dealerships , do not want to work on it the truck is currently sitting in a mechanic shop.All receipts of work done and affected parts is in the truck at mechanic so I have receipts for all of this

I own a 2016 Ram 1500 EcoDiesel, VIN [XXX] . The vehicle has been in and out of Rydell Jeep & Ram dealership over 3 times in the last few months for fuel pump issues. It has been at the dealership for over a month total (in and out). Each time I have had to pay for towing and rental cars. I have not been reimbursed for any rental or towing costs. On April 11, 2026, immediately after picking up the truck from the dealership (where it had just been serviced for a previous fuel pump issue), the vehicle suddenly lost all power while I was driving on the freeway and would not restart. It was towed back to Rydell. On April 23, 2026 at 9:30 AM, Bruce (service advisor) and Mike (mechanic) at Rydell verbally admitted to me that their original diagnosis was wrong. They had initially said a gear inside the engine that turns the CP4 fuel pump had come loose or failed. They now admit that diagnosis was incorrect, but they refuse to provide that admission in writing. They are now trying to charge me for the repair. I believe the actual root cause is that the CP4 high-pressure fuel pump seized internally. That seizure would have placed extreme resistance on the engine's drive gear for the pump, causing the gear or its retaining bolt to fail as a secondary consequence. The pump seizure is a known safety defect in these EcoDiesel vehicles. Because the dealership has admitted the original diagnosis was wrong, and because this failure happened immediately after fuel pump-related service, I am requesting that NHTSA investigate this as a safety defect. The sudden loss of power at highway speeds is extremely dangerous. I also request that any existing recall or investigation (such as NHTSA Campaign 22V406000 a INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

During a routine oil change test drive, a code for Crankshaft Loss of Position appeared on my truck and as a result, the autoshop I took it to (a Kerry's Car Care) recommended that I do not drive it. This is an active Recall from the FCA from the NHTSA (Safety Recall W68 / NHTSA 20V-475 Loss of Crankshaft Position), but Dodge is insisting the recall was repaired (66A/NHTSA 23V-411) but only an update to the software as issued, without replacing the actual faulty part, the tone wheel. This problem was discovered and inspected by the Kerry Car Care, but I anticipate that Dodge Chrysler will deny the repair, even though it is a safety recall issued by the FCA. There were no signs of failure prior to the test drive done at Kerry's.

On September 29, 2025, my vehicle overheated. Smoke was coming from the interior vents as well as from under the hood. I pulled over shortly after and had my vehicle towed to a repair shop. I got an estimate for radiator repair. That did not fix the issue, so more repair was needed related to a heating and evaporator core. I have attached the invoices for those repairs. I just wanted to note this for my records.

I own a 2016 Ram 1500 EcoDiesel (VIN: [XXX] ). This vehicle is covered under the EcoDiesel Approved Emissions Modification (AEM) Settlement extended warranty. Since the update in January 2025, the truck has suffered repeated EGR system failures and related warranty failures. The EcoDiesel lawsuit itself was based on EGR cooler defects that could leak coolant and cause fires. My truck has experienced the same failure pattern, with coolant leaks, overheating, and unsafe breakdowns. On [XXX], the vehicle shut off in the middle of the road while I was driving, creating a serious hazard. The cause was traced to a covered emissions component. This was not an isolated incident. The vehicle has been in dealerships for over 60 cumulative days since January 2025, mostly for repeated EGR codes and fuel system issues, but the root problem has never been properly repaired. On [XXX], the low-pressure fuel pump failed after it had already been replaced. The premature failure left me stranded and required a $500 tow. This failure also presented a risk of sudden power loss in traffic. Despite repeated visits to authorized dealers, repairs are incomplete or improperly billed, including installation of non-OEM parts that failed again. The repeated stalling, coolant leaks, overheating, and sudden no-start conditions show that this truck remains unsafe to operate on public roads. I am reporting this as a safety defect because the emissions system failures and improper repairs have caused the vehicle to shut off while driving and continue to present a risk of fire, engine damage, and sudden loss of power.

They called me and told me it was ready. the following week and told the Intake Manifold failed and needed to be replaced. I gave them go ahead to repair it. They told me the Intake manifold replaced and ready for pick-up. When I went to pick it up, on 22 July 2025. The Tech showed me the intake manifold; it looked like it had melted. He also said the water pump was leaking and should be replaced. I paid for the repair for the intake manifold, left the truck and drove my car home, intending to have someone run me there and I would drive the RAM home. After thinking about a day or 2 I called John Johns and told them to go ahead and replace the water pump and took the key back to them. I didn't want it to fail when I was least expecting it. AT this point I've spent $4,750.20. They called I went and picked the truck up on 23 Jul 25, drove it home (20 miles) on [XXX] I just pulled out of my driveway, check the rearview mirror and saw all this white smoke coming out of the exhaust.
