SERVICE BRAKES, ELECTRICAL SYSTEM, POWER TRAIN
Brand new truck (497 miles) while driving on freeway at 70 mph, truck kicked out of cruise control and threw traction control, adaptive cruise control, 4wd, check engine, and anti lock brakes disabled fault lights and codes. The vehicle will disable all these safety features for 30-50 miles, and then the faults will randomly disappear except for the check engine light. This has happened 10-12 times. This truck has had 4-5 “ram cares” case numbers, has been at the dealership for over a month combined. The faulty part supposedly is a right rear wheel speed sensor on the 12” dually axles. There is hundreds if not thousands of these trucks affected. Stellantis/ram says the sensor is has been updated, but is currently not built or for sale., there is a national backorder. We are being told to drive these trucks while ram comes up with a fix. These speed sensors affect systems that have been federally mandated since September of 2012 (anti lock brakes). They are putting customers and other drivers on the road in danger with the intermittent failure of the brakes and traction control in wet conditions.

POWER TRAIN
While driving on interstate leaving a construction zone started to accelerate to maybe 40mph and heard/felt a hard clang and lost all forward motion costed to side of interstate. Looked underneath truck, nothing visible broken or leaking. Restarted truck tried to move forward with no luck. Reverse worked, put back in drive loud noise again stomped on the accelerator and started moving forward very slow and difficult. Made it to an exit to look at things in a safer location than the busy interstate. Figured out that I had reverse and 5th gear so it was very hard/ slow to get moving. Check engine light on, gear ration incorrect, code P0731, Tran sensor failure, no 4x4 Transmission failure 1-4 gears not working

VEHICLE SPEED CONTROL
I have experienced two major issues. The dash cluster went blank. Not able to see any of the gauges. Vehicle ran, drove. Turned the truck on and off. Opening & closing the door to power off the truck. 15+/- minutes for the dash to return to normal. Supposedly an update to the program is pending. Second and major issue; while backing up, the truck came to a stop by itself, blocking an intersection. I was not able to place the truck in any gear. Warning light notified me that the truck was not in park. We were unable to push the truck out of the intersection. The dealer says when the "Wheel Speed Sensor" failed the truck is programed to be immobilized. I have recently returned from a trip to the Rockies pulling a 35 foot 5th wheel RV. I have traveled several mountain roads. One 12 mile stretch with a 8% grade. Had the wheel sensors failed on any of these roads the chance of and accident were great. Potentially deadly. This is a known issue. Ram has decided to use the newly redesigned parts for production of new vehicles. No parts are available or estimated ship date. My truck has been towed to Capitol Ram of Garner, NC and will sit until Ram decides to provide parts. Part numbers: 68646345AA Left & 68646344AA Right

TIRES
I purchased a dodge 3500 truck on October 16th 2024. My truck as of today has 4900 miles on it. It is a one ton dually. I noticed this week two of the rear outside tires have cracks and defective tread. I took it to a tire shop and they confirmed these tires are bad. I tow a 40 foot fifth wheel trailer. If I had had a blowout it could of been a huge problem for myself and those on the road around me. I spoke to the dealership I bought the truck from and they informed me they would have to see the tires and file a report with the manufacture of the tires. I had to buy all 6 new tires because I didn't want to chance a blow out with my trailer on the truck. I googled Nexen tires LT235/80R17 which are my tires. It says these are not rated for a 1 ton dually truck. When used on a dually it says its not the best choice for a 1 ton especially when towing heavy loads. The reason I bought this truck was for the purpose of towing my RV. I made that clear to the sales man at the dealership when I bought this truck. I assumed these tires were rated for this truck. If it's a defect I should be reimbursed from the manufacture for all 6 tires. If it's the dealers fault they should reimburse me. This is definitely a road hazard, a accident waiting to happen.

STEERING
The contact owns a 2022 Ram 3500. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the electric power steering was not functioning properly, requiring an increased effort to maneuver the vehicle. The contact was able to pull over to the shoulder of the roadway, where the vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the wiring harness connector due to water intrusion, resulting in damages to the electric power steering control module. The contact was informed that the connector seal had failed to prevent the entrance of water leading to water damage. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 20,000.

POWER TRAIN, UNKNOWN OR OTHER
Excessive Diesel Exhaust Regeneration. Vehicle in in regeneration about 72% of the time. Check engine light comes on about every 2 weeks with code P2459. The P2459 code indicates an issue with the diesel particulate filter (DPF) regeneration frequency in diesel vehicles. This code is triggered when the powertrain control module (PCM) detects that the DPF regeneration process has not occurred as expected. Have to take to dealership for a manual regeneration and to clear the code. Dealership says this is a known issue for Ram Diesel engines from 2018-2024. Dealership says Ram has yet to address the issue even though its been 7 years since the issue started in the 2018 model year. Been dealing with this for a year now.

SERVICE BRAKES, ENGINE, POWER TRAIN
Vehicle died in a busy intersection coming off the freeway. Light flashed that indicated it was an issue with the electronic throttle control. The safety of myself and others was put at risk due to the posted speed of the road and multiple lanes from 4 directions. I had to remain in my vehicle to make sure I was not hit by another vehicle and due to the vehicle issue, I was impeding traffic. Lithia Dodge of Grants Pass, OR stated they could not make an appt for the vehicle to get looked at for 2 weeks out, scheduled 8/22/25. Dealership seems to think this is not an issue with safety and this issue can occur while the vehicle is in motion which is a huge safety issue. No warning lights flashed before the first one indicating the vehicle would shut down/lose all power.

SERVICE BRAKES
The brakes do not apply until after the pedal reaches half of its travel distance and still not as good they should. Very soft pedal feeling and too long of pedal travel to apply brakes. Very unsafe! I have had it to the dealer 3 times for this condition since I had purchased it (New) on June 5, 2025. They bled the brakes and found a small omaunt of air in the system. This did not change the braking condition at all. They cannot seem to find the problem. Service advisor did tell me that recently another customer brought in his 2024 Ram heavy duty pickup with the same issue.

ENGINE
Failure of hydraulic lifters and camshaft in Cummins 6.7 liter diesel engine of 2021 RAM 3500. Engine exhibited significant ticking noise and the engine does not work properly, putting the safety of driver and passengers in vehicle at risk. Vehicle is not driveable. This issue has been confirmed by the RAM dealership in Livingston, Montana. The 2021 RAM 3500 truck has been sitting at the RAM dealership for the past seven weeks awaiting parts and a fix that RAM trucks is still trying to figure out. Apparently, this has become a common problem with the RAM Cummins 6.7 liter diesels from model years 2019 through current 2025 models, including 2021. The RAM dealership in Livingston, Montana has five separate RAM Cummins 6.7 liter diesel trucks with the same issue awaiting parts and a fix from RAM.

SERVICE BRAKES
As I was exiting the highway with a loaded trailer carrying approximately 10,000 pounds, the ABS and brake warning lights illuminated on the dash, along with a “No Trailer Brakes” notification. When I applied the brakes to slow down, there was little to no braking response. Fortunately, I was able to safely pull off the road. The truck has now been at the dealership for two weeks, and the technicians have yet to identify a solution.

EXTERIOR LIGHTING
Every time I turn my left turn signal on my headlights high beams come on weather headlights are turned on or not even if I have my headlights on on low beam, it does not do it when I turn my right turn signal on. It does it whether I have my auto headlights on or off. I'm sure it's been happening longer than that that's just the first time I was informed by someone I was following on the highway

POWER TRAIN
The transmission in my vehicle failed suddenly on May 31, 2025, entering “limp mode” and losing the ability to shift properly. The vehicle became immobile and was towed to the dealership. Initial diagnostics revealed difficulty shifting between 3rd and 4th gears. Service technicians attempted repair in June based on RAM TSB MC-10231775, which indicated snap ring failure in the Aisin transmission. Repairs prescribed in TSB were attempted but unsuccessful, as the vehicle still could not shift into 4th gear. Additional parts were ordered, and another repair was unsuccessfully attempted in late June. Ram has shipped a new transmission which we are waiting on the dealership to install.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
We bought our 2024 3500 Dodge RAM in Florida in late March. Last weekend the truck started to feel like it was jerking while we were pulling our 5th wheel. On Monday we schedule an appointment in Brockton Massachusetts at a dealership. We were told there need to be a system update and that it was all set. On Wednesday we started our 3 hour drive to Maine when suddenly while we were on the highway the truck began to overheat and revving loud only going 35mph. We pulled over into a parking lot and called RAM roadside assistance. We were told to let the truck cool down and try again. After being in a parking lot with our 4 kids and 2 dogs in 100 degree weather for 6 hours we attempted to start the truck. However every time we put it in drive the truck shut off. At this time we had to get it towed for $300, today the local RAM autoshop is saying they looked at the truck and transmission is gone. They are also saying they will not be able to look at the truck for a month. We travel full-time in our RV and now are stranded with our RV and no way to pull it anywhere.

TIRES:TREAD/BELT
Nexen Roadian HTX RH5 LT235 / 80 R 17. While driving down interstate and pulling a 21,000 lb GVWR fifth wheel trailer, the truck began vibrate. After stopping it appeared that the front passenger tire was out of round. This was confirmed after jacking up the vehicle. Suspect internal damage to the radials. The tire had a total of 16,600 miles on it. Tire had cold pressure of 80 psi and was just checked 4 days prior to the incident. Luckily, the issue was discovered prior to a catastrophic failure, so no damage or accident occured for this particular failure.

FUEL/PROPULSION SYSTEM
My 2022 RAM 3500 has repeated failures of the diesel particulate filter (DPF) system. The truck enters limp mode unexpectedly, including while towing on the interstate, creating a serious safety hazard due to sudden loss of power. Since purchasing the vehicle, I have experienced ongoing issues with the emissions system, specifically related to the DPF. The check engine light comes on frequently, and diagnostic scans consistently show code P2459 (Diesel Particulate Filter Regeneration Frequency Too High). The DPF system has been replaced approximately five times by authorized RAM dealer. Despite these repairs, the same problem continues to occur. The truck will sometimes enter limp mode without warning, drastically reducing engine power. This has happened while towing a camper on the interstate, making it difficult or impossible to maintain safe highway speeds or accelerate when needed. This puts me, my passengers, and other motorists at risk of a crash, particularly when merging or changing lanes in fast-moving traffic. I have already pursued and settled a claim with Stellantis (RAM’s manufacturer) for $10k due to these issues. However, the problem persists, and the root cause has not been resolved. Accepting the settlement was recommended by legal counsel. The failure has occurred on multiple occasions (at least five separate incidents). The vehicle has undergone several service visits and emissions system replacements, but the safety issue continues. Current mileage 42,000. Dates of incidents from most recent: 6/25 (still in shop), 3/25, 9/24, 8/24,7/24,6/24,4/24,1/24,7/23,6/23,11/22. Documentation available upon request. Diesel particulate filter (DPF) system replaced approximately five times. I believe there is a defect in the design or operation of the emissions system that poses a safety risk. Loss of power while driving at highway speeds or towing creates a dangerous situation. I am reporting this in hopes that NHTSA will investigate this recurring issue.
