episode of vehicle locking up while going down interstate at 70 MPH with loaded trailer attached. This places the driver and passengers at risk for injury and/or death. Per the dealership, they have not been able to reproduce the issues but stated that it is unrepairable. No manufacturer inspection has been completed. Warning lights and warning messages have been present since before first return to dealership on 4/9/26, 6 days after purchase of vehicle, for TPMS issues, inaccurate speed odometer, and incorrect lift kit installation.
My 2024 Ram 3500 DRW (about 23,000 miles) has a recurring water intrusion problem in the cowl and HVAC area. During ordinary rain it collects there while parked outside and then floods out onto the front floor carpet. After a rain on [redacted], the air conditioning stopped blowing cold air; when I checked on [redacted] the cabin filter was completely flooded with water and I replaced it that day. The same flooding recurred after rains on October 14 and again on October 30. I covered the windshield and cowl area...

before the last rain to try to keep water out, but that did not work. The truck will not fit in a garage, so every storm risks flooding the cab again. On [redacted] I reported this problem to [[redacted]] Chrysler Jeep Dodge Ram (Group 1 Automotive) in [[redacted]]. They said it would take about a week before they could look at it, and on that first visit they also suggested the issue may not be covered under warranty, implying lack of maintenance rather than design. I asked for an appointment where they could inspect it right away so it did not sit in their lot exposed to more rain; we set November 2 at 9:00 AM. The truck is back there this morning and they are still inspecting it. The water intrusion has already caused additional damage. The air conditioning blower motor makes a grinding noise at medium speed or higher, likely from water getting into it. After three full floodings I am also concerned about mold growing in the carpet and padding under the front floor. Stellantis has no service bulletin or recall covering this water intrusion on Ram HD trucks, though other owners report the same problem across model years. This truck is new and maintained per schedule. Please investigate whether this is a design defect affecting 2019 through present Ram 2500 and 3500 HD trucks, given the mold risk in the cab and possible water damage to electrical components under the front floor.

ONLY 1,800 MI. I continue to experience ongoing issues with this truck, despite having just received it back from the dealership two weeks ago following repairs related to a rear pinon gear. the truck is now back in the service department for concerns involving the front differential. Given the repeated drivetrain issues, I am increasingly concerned about the safety and reliability of this vehicle, particularly the possibility of a catastrophic mechanical failure while traveling at highway speeds that could result...

in loss of control. These ongoing problems have significantly undermined my confidence in the vehicle's safety and dependability. At this point, I am concerned not only about the continued mechanical problems but also about the potential risks to my safety and the safety of others on the road. I believe these concerns warrant serious attention and a resolution as soon as possible.
Odometer Fraud. The contact purchased a 2018 RAM 3500. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 105,000; however, the contact discovered through the original owner of the vehicle that the current mileage was 217,000.
All of my dash board light lit up. I stop the truck turn it off. when I get back in to drive it would not engage the transmission. No reverse No drive and the engine would not shut off. Happened about two weeks ago. the first time what in December, Same problem! they say it just needed a software flash, but if that was the case why would it happen again, and why would they need another software flash ?
Since first test driving the truck in March of 2025, there was an issue with the ABS system warning coming on. When that happens, it also disables 4 wheel drive, electronic stability control, cruise control and trailer brakes. The first 3x it happened while NOT towing at about 45mph. Other times it happened while towing a 16,000# trailer which caused vehicle control issues when braking. I did however discover, in a panic, that the manual trailer brake lever still works. The cause of the ABS system shut down was...

determined to be code: C0037-2F (Left Wheel Speed Sensor Signal Erratic) It has be brought in to the dealer for repair at the following mileages: 4,478, 4,699, 13,790, 14,745 and 16,487 miles. Since then, the wheel speed sensor has been replaced along with the "tone ring" and other components. Most recently, it was determined that the main wiring harness was pinched and (2) wires for that circuit were shorted. The dealer ran (2) new wires outside the wiring harness. The new wire were also NOT sleeved as per SAE vehicle wiring specifications. They "said" they removed the fuel tank to access the repair, however forensic evidence does not support that. There is still undercoating on the bolt threads. It should have been disturbed or worn off when removing the fasteners. After the repair was made, the problem once again came back while towing a smaller 5,000# trailer on 10/4/26 at approximately 16,654 miles. The failure has occurred about 8 times now since the initial repair was made.
On my 2019 RAM 3500, I reported a problem with th eNHSTA back in 2023, and NO response yet. This is about the integrated brake controller, that provides NO electrical signal to stop the towed trailer at speeds what apear to be below 35MPH. This is a very dangerous failure on these trucks.
towing control module, brake lights work trailer breaks will not grab, lights on the module do not come on the module has never worked since I bought the 2024 dodge 3500 dually diesel
On the morning of August 29th around 8:10am the Ram truck caught fire under the hood with the engine/ignition off, after it was driven around the yard lot and shut off. The fire seems to have originated in the center of the engine on the drivers side of the cylinder head. Mimicking the same patterns as the recall #13A in regards to the heated grid recall that was performed in March of 2025, @121338 miles. The truck now has 157032 miles. The driver was able to extinguish the fire before the fire spread beyond the engine bay. the truck is currently locked up on site at our facility.
The contact owns a 2025 Ram 3500. The contact stated that shortly after purchasing the vehicle brand new and filling the fuel tank on December 3, 2025, the DEF depth gauge failed. The vehicle was taken to a dealer, where the module was reprogrammed and the physical gauge was replaced. However, the contact obtained internal service notes revealing that the urea pump, the DEF tank, the urea tank wiring harness, the DEF injector, and the fluid had actually been replaced due to an active fuel leak within the DEF...

system. On March 31, 2026, the vehicle was taken back to the dealer to address a malfunctioning digital rearview mirror. While at the dealer, a recall repair was performed under NHTSA Campaign Number: 25V882000 (Air Bags, Electronic Stability Control (ESC)). The digital mirror was replaced; however, the failure recurred immediately. In May 2026, the vehicle was returned to the dealer for the ongoing mirror issue; however, the service notes only indicated that a part adjustment was performed, and the defect persisted. The contact then took the vehicle to a second dealer to repair the digital mirror and address the DEF system, as the warning light had re-illuminated on the instrument panel. During this visit, the second dealer performed a recall repair under NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System). While the dealer claimed to have serviced both the DEF warning light and the mirror, the mirror failure remained unresolved. After spending a cumulative month at the dealer, the vehicle was diagnosed with an illuminated check engine light caused by a recurring DEF-contaminated fuel leak. The dealer replaced the entire DEF assembly, including the fuel system components, and cleared the DTCs. In July 2026, the vehicle was returned to the dealer yet again for another digital mirror replacement, which failed to resolve the issue. The contact believed there was an inherent manufacturing flaw at the top of the fuel tank causing the repeated DEF system failures. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 1,000.
On multiple occasions the U-Connect system in the listed 2026 RAM 3500 has gone completely black and was inoperable until a reset was performed. The trailer brake gain control and exhaust brake are accessed and controlled via the touch screen U-Connect system. This failure poses a significant safety issue when the screen goes black and the controls cannot be accessed when pulling a trailer. This can lead to failure to slow/stop the vehicle while in motion, tire failure on the trailer etc. The only method to...

regain access to the brake controls is to perform a reset of the U-Connect system which can take 2-3 minutes to complete. Stelantis is and has been aware of this issue for some time and has no resolution at this time.
When driving the Anti lock brakes, cruise control, front and rear collision warning system, automatic emergency breaking system and lane keeping system are disabled. All of these alerts are displayed on the display cluster. All of these systems are disabled at the same time. I was told by the dealership that this is caused by a faulty Wheel Speed Sensor. The Wheel Speed Sensors have been replaced 3 times and have not fixed this problem. This has happened when towing a 14,000lbs trailer and the stability of the truck and load are compromised when breaking with a load.
I have been submitting reports to you for several months with no resolution. The truck yet again experienced the same problem, twice, within 1 week. It would start but then claim that it couldn't detect what gear it was in and said "can't shut off until transmission is in park". After cutting electrical power to get it to shut off, it would not start. After getting it started, it would not go into gear. Once I got the engine running and transmission to go into gear, it no longer had ABS.
The 2025 and 2026 dually 3500 Ram trucks with the 12" AAM rear axle are having issues with the rear wheel speed sensors (different sensor for each side). They apparently fail or are not able to properly communicate to the computer. When this happens, the following are disabled: -ABS -Auto Emergency Braking -4x4 -Electronic Stability Control -Cruise Sometimes, the engine won't shut off. The gauge cluster will state it can't detect which position the transmission is in. So, you cannot shift, and you can't shut the...

truck off, and you can't drive. You are stuck in place with a running engine. Despite Stellantis releasing a new revision of wheel speed sensors (AB revision), they have failed in less than 2,000 miles on my truck. Many, many dually owners are experiencing these failures.
The contact owns a 2026 Ram 3500. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated. The message that the trailer was not connected was displayed. The contact received notification of NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was 11,000.
