Loss of various systems while towing 14,000# trailer in hilly terrain. Loss of trailer brakes caused diminished control on the vehicle. * 4WD System Temporarily Unavailable * Service Antilock Brake System * Service Electronic Stability Control * Service Trailer Brake System The issue was previously repaired 3x. The problem originally happened 3x on the same road in the same spot. Right turn off a road, then going up hill. The first 2x lasting less than 10 miles. The 3rd, approximately 6,000 miles. This time (4th) it happened while towing 14,000# trailer. Made a left turn, then proceeded up a hill. Scanned the truck and got code C0037-2F. "Left Rear Wheel Speed Sensor Signal Erratic". Possibly issue with body / chassis / suspension flex or internal axle component being loose. The sensor was already replaced 2x, along with other components under warranty.

PTC heater short circuited, overheated and scorched/melted itself as well as other plastic Hvac components and sent toxic fumes into the passenger compartment via the HVAC vents. This truck has been in 2 different Dodge dealer service departments multiple times for the same failures. After repairs were performed, the same failures occurred on the way home from the dealer. The PTC heater grid sits INSIDE of the HVAC airway. I am now experiencing multiple adverse medical symptoms from these exposures.

This complaint involves a 2024 Ram 3500 with an unresolved electrical system issue associated with the rear backup camera and related wiring. The vehicle initially presented with a malfunctioning backup camera, including unclear or distorted image quality, which affects rear visibility and safe operation while reversing. The vehicle was taken to authorized dealerships for repair on multiple occasions. During the course of these repair attempts, the wiring associated with the system was damaged, resulting in an ongoing electrical system issue that has not been resolved. The vehicle has now been out of service for approximately 71 days. Most recently, the authorized dealership confirmed that the required parts to complete the repair are unavailable, there is no estimated timeline for parts availability, and the repair cannot be completed at this time. As a result, there is currently no repair plan in place. This situation raises safety concerns due to the loss of a critical safety feature (rear visibility via the backup camera) and the presence of unresolved electrical system damage. Damaged or compromised wiring may create the potential for electrical malfunction, system instability, or other hazards if the vehicle were to be operated. The inability to repair the vehicle, combined with the lack of available parts and absence of any repair timeline, raises concerns about the overall safety and reliability of the vehicle. The vehicle remains at the dealership and is available for inspection.

RAM 3500 truck was purchased in Ventura, CA and has experienced multiple electrical and drivetrain failures beginning shortly after purchase. In January 2025 while traveling in Oregon, the infotainment system repeatedly blacked out and the cruise control button stopped functioning. A dealership replaced the cruise control button, restoring cruise control, but the infotainment problem remained. When the vehicle was returned after the repair, a new defect appeared: the horn button no longer worked. Loss of the horn creates a safety risk because the driver cannot warn other vehicles or pedestrians. Around 20,000 miles during a routine service visit at the selling dealership in Ventura, we reported a driveline vibration. The dealership and the upfitter inspected the vehicle and observed tire cupping. They checked the tires for premature wear and recommended overinflating tires as a remedy. The vibration continued and worsened, the infotainment failures persisted. In October 2025 while driving in Wyoming, the vehicle experienced a major drivetrain failure involving the front differential and axle assembly and required towing. The truck was first towed to the Yeti dealership in Afton, Wyoming, which closed shortly after the vehicle arrived. The truck then had to be towed again to Yeti dealership in Jackson Hole. There, technicians diagnosed front differential and axle assembly as the primary failure and also observed premature wear on aftermarket shocks installed by the upfitter. Technicians indicated the differential assembly was not readily available and would require special order. The vehicle was later transferred to another dealership in Dodge City for repair, but the differential components were not immediately inspected or ordered, causing additional delay. The vehicle remains out of service awaiting drivetrain repair. Safety concerns include horn failure, repeated electrical malfunctions, and drivetrain failure while driving.

On 01/21/2026 there was a warning light that came on stating accelerator control sensor, the next morning the truck started stalling, and continued stalling multiple times. I attempted to get the vehicle to the service center. It then stalled 2 more times, the service center told me they couldn’t look at the truck until the next day, the vehicle then stalled on me again that evening, they kept the truck until Friday evening, and told me they couldn’t duplicate the issue. They knew it had happened, but they couldn’t find the cause without replacing a bunch of parts until they found the correct issue. I took the vehicle home, started it the next morning and the maintenance required issue again returned, I took it back to the service center, they checked the codes, and told me it shows the 3rd taillight is staying on which indicates usually a fuel issue. They then sent me a quote stating a bunch of things that’s already been done to the vehicle outside of their service center, as well as the part they told me was where they had started to diagnose the issue and it didn’t work, all of which are not covered under the current warranties of the vehicle and basically the way I understood it that I would have to keep buying parts and replacing things out of pocket until the drivetrain issues were resolved.

The dealer was notified and informed the contact that it was a new vehicle odor. The contact stated that while driving at 65 MPH, the contact noticed clear smoke coming from the vents. Additionally, the contact stated that the rearview was inoperable. The vehicle was taken to the dealer, where it was diagnosed that the cab heater had experienced an internal short circuit, causing the wiring and grid heater to melt. The vehicle was repaired; however, the failure recurred while driving. The contact sustained extreme fatigue, sore throat, nausea, headaches, ringing ears, and vomiting. The contact had not received medical assistance but had taken a 3-day leave from work.

Truck wiring harness is rubbing against the front driver's side body mount, this is a known issue on these trucks, and causes the wiring harness to start rubbing, causing electrical failures, and may cause accidents. Others have stated this occurred to their truck before it reached 50,000 miles. I just checked my 7,000 mile, and found the wiring harness was rubbing.
