2024 RAM 3500 Brakes Problems

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.

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.

While traveling down a hill, about 40mph, applied brakes to stop at a T intersection, truck wasn’t slowing down. Engaged engine brake, truck wasn’t slowing. Slammed brake pedal to the floor, ABS did not engage, no vibrations, wheels didn’t lock up, held for 2-3 seconds then started to release and slam brake pedal repeatedly. Truck went through intersection, hit a lot of trees, dropped down a 6’ embankment, air bags did NOT deploy, trucks frame bent on both sides behind the cab.

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.

When applying the brakes when coming to a stop, just before the truck comes to a full stop the brakes grab and release. If I let off the brakes right before I stop it is way worst. This is a major concern for my safety and my family's safety.

The contact owns a 2024 Ram 3500. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed, and the ABS warning light illuminated. The contact forcefully depressed the brake pedal to stop the vehicle. The vehicle was taken to the dealer, where it was diagnosed that the ABS module had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 96,000. The VIN was not available.

Mileage

96,000 mi

Vehicle displayed warnings: Service Antilock Brakes Service Electronic Stability Control Service Trailer Brake System The truck has only 4,650 miles on it. When this happens, the above systems do not work along with the 4 wheel drive system. When towing a heavy trailer, the loss of trailer brakes can easily cause an accident due to jackknifing of the trailer and greatly increased stopping distance. Loosing 4 wheel drive in snow or mud can cause an accident or getting stuck.

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 did. It gives me maximum voltage for full braking from the fifth wheel at any speed. I should also state that my truck was new with only 2500 miles on it. I was not informed by the dealer or able to gain knowledge of this controller design anywhere in the Ram information provided in the owners manual. This is an extremely hazardous design not permitting maximum braking at slower speeds.

Truck was parked on 5% slope, and transmission shifted into park, and parking brake set. Transmission then made a popping noise, and shifted into reverse, and vehicle started moving backwards. Parking brake failed to hold vehicle. Applied brakes, and shifted into park again, and set parking brake, and it didn't reoccur.
