2024 Ram 3500 problems

Filed Nov 2, 2026 · Body, Electrical · OK

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 xxx, the air conditioning stopped blowing cold air; when I checked on XXX 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 XXX I reported this problem to [XXX] Chrysler Jeep Dodge Ram (Group 1 Automotive) in [XXX]. 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.

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.

The truck has a CEL P2459. The unit was taken back to the dealer on June 15, 2026, and they diagnosed an aftermarket air cleaner and regeneration. The CEL continued to display P2459, and I returned the truck to the dealer on 9/23. The dealer stated I had a defective air cleaner housing and was willing to pay 80% of the cost. They also said the restriction likely caused the DPF filter to plug because it caused excessive DPF generation. I believe this defective air housing may be on multiple units since these are likely purchased in batches. Ram should replace all air cleaner housings from the manufacturer batch related to my unit. They should also cover any parts caused by this defective air cleaner housing. Ram should cover the plugged Diesel Particulate Filter and the air cleaner housing.

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.
