I was towing a 18000 lb fifth wheel rv about 45 mph when traffic made a panic stop in front of me. I couldn’t stop and had an accident. I later determined the brake controller on truck didn’t provide the 12 volts needed to get maximum braking from the fifth wheel brakes. I took it to the dealer and they confirmed that at slower speeds it doesn’t give maximum voltage. They contacted Ram engineer to find a fix but was informed that that it was operating as designed. This controller design was definitely the cause of this accident. I was only getting 8 volts for the trailer brakes. I contacted Cargo Brake ( manufacturer of trailer brake system) and they told me they have had many complaints from Ram owners about this problem. They recommended that I purchase an aftermarket controller which

I was towing a 6,000 pound excavator on a 20’ tilt deck trailer and rounded a turn to see a line of traffic stopped waiting on a big truck to turn. I hit the brakes and the truck didn’t start to slow. I swerved to the shoulder and pressed breaks as hard as possible and went past several cars and t boned the big truck that was turning. The only brakes it felt like i had was the trailer brakes. Very severe accident that everyone walked away from but definitely was equipment failure involved.

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".

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.

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.
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 t
brakes 2 complaints shown
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.
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.

tires 1 complaint shown
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 say
suspension 1 complaint shown
The truck is in for its second front end alignment. I bought it brand new in October 2024 and it has about 43000 miles on it. I'm concerned for my family's safety. If it is going out of alignment this often, I don't feel safe driving it. The dealership has no explanation of why its going out so fast. I know I'm not the only one having this problem. There are thousands of people saying they are having the same issues. It was out of alignment from the factory. Pretty much all of them are. Something needs to be done about this. I put today's date but the first time I took it in was less than a year and 20000 miles ago.

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
