2024 Ram 3500 — Known Issues & Recalls

Your brakes feel very soft and require you to push the pedal more than halfway down before they start to work effectively. You've brought your truck to the dealer three times since purchasing it new in June 2025, and they've bled the brakes and found some air in the system, but the problem persists. The dealer has confirmed that another 2024 Ram heavy-duty truck owner reported the same issue. This likely requires a thorough brake system inspection to identify why air keeps entering the system or why the brakes aren't responding correctly.

While exiting the highway with a loaded 10,000-pound trailer, your ABS and brake warning lights came on along with a "No Trailer Brakes" message. When you pressed the brakes, they responded little to not at all, though you managed to safely pull off the road. The dealership has had your truck for two weeks without finding or fixing the problem.

When you apply the brakes to come to a stop, the brakes suddenly grab and release just before the truck fully stops. If you ease off the brakes slightly before stopping, the problem gets worse. This unpredictable brake behavior could affect your ability to stop smoothly and safely. The issue likely involves the brake system's anti-lock braking (ABS) or brake pressure control and may require a brake system diagnostic and possible component replacement.

While towing a 6,000-pound excavator, your truck's brakes failed to respond when you tried to stop for stopped traffic. Even with maximum brake pressure, the truck continued forward, forcing you to swerve onto the shoulder before colliding with another vehicle. You felt only the trailer brakes were working, suggesting the truck's primary brake system did not function during this high-speed emergency stop.

While braking on a hill at 40 mph to stop at an intersection, your brakes failed to slow the truck despite applying full pressure and engaging the engine brake. The ABS system did not activate, and the brakes began releasing and re-engaging on their own. Your truck went through the intersection, hit trees, and dropped down a 6-foot embankment. The airbags did not deploy during the crash, and the frame was bent on both sides behind the cab. This will require a complete inspection of the brake system, ABS module, and airbag system to determine why they failed.

Your 2024 Ram 3500 has experienced multiple serious problems since purchase, including a non-functioning horn (creating a safety concern since you can't warn other drivers), repeated infotainment system blackouts, and a major front differential and axle failure that left you stranded and requiring towing. The truck also developed a driveline vibration around 20,000 miles that worsened over time. Repairs will likely involve replacing the front differential and axle assembly, as well as diagnosing and fixing the electrical issues affecting the infotainment system and horn.

Your cabin heater has overheated repeatedly and has been replaced three times since November 2025, but the problem persists. Each time it overheats, it fills the passenger compartment with toxic fumes, creating a potential fire hazard. The vehicle is still at the dealer and the issue hasn't been resolved. Fixing this will likely require a complete replacement of the PTC heater unit and a thorough inspection of the electrical heating system to identify the root cause of the repeated overheating.

Your 2024 Ram 3500 experienced a cab heater malfunction where internal wiring and the heating grid melted, causing clear smoke to pour from the vents while you were driving at 65 mph. You also noticed an abnormal odor in the cabin and your rearview camera became inoperable. After the dealer repaired the heater, the same problem happened again shortly after. The repair involved replacing the faulty heater assembly and associated wiring.

Your truck started jerking while towing your fifth wheel, and after a system update at the dealership, it began overheating and revving loudly on the highway while only able to go 35 mph. When you tried to restart it after cooling down, the truck shut off every time you put it in drive. The dealership is indicating that your transmission has failed and cannot service it for a month.

Your backup camera isn't working properly and is showing unclear or distorted images, which makes it harder to see behind your vehicle when backing up. When the dealership tried to repair it, they damaged the wiring, and now there's an unresolved electrical problem. The dealership says they don't have the parts needed to fix it and don't know when they'll be available, so your truck has been out of service for over 70 days with no repair plan in place. Getting the backup camera and its wiring repaired will likely require replacing the camera unit and repairing or replacing the damaged wiring harness.

Your backup camera stopped working intermittently and then failed completely, showing only a black screen when you tried to back up. This created a safety risk since you couldn't see behind the vehicle while reversing. A Ram dealer diagnosed an internal malfunction in the camera itself and replaced it with a new one.

After your engine was replaced, your truck continues to run unreliably and isn't dependable enough for you to use in your business. You're experiencing ongoing performance issues that weren't resolved by the engine replacement work.

Your truck displayed an accelerator control sensor warning light and then began stalling repeatedly. The service center initially couldn't identify the cause, but later found a diagnostic code related to the third taillight staying on, which they said typically points to a fuel system issue. They've quoted you for repairs involving parts and diagnostics that aren't covered under warranty, and you're concerned about having to replace multiple components out of pocket to resolve the stalling problem.

Your check engine light has come on 8 times since November 2025, forcing you to shut down work multiple times. Your truck now has 43,000 miles and the dealership says they don't know what's causing the problem. The issue likely involves a fault in the engine or fuel system that needs proper diagnostic testing and repair.

Your new 2024 Ram 3500 dually arrived with Nexen LT235/80R17 tires that developed cracks and defective tread within the first 4,900 miles. A tire shop confirmed the tires are defective, and you discovered these tires are not rated for use on a one-ton dually truck, especially when towing heavy loads like your 40-foot fifth wheel trailer. You had to purchase all six replacement tires out of safety concerns. Resolving this will require the tire manufacturer and/or dealership to investigate whether this is a tire defect or an inappropriate tire specification for your truck's intended use, and to determine responsibility for reimbursement.

Your diesel engine's exhaust filter is regenerating (cleaning itself) almost constantly—about 72% of the time—which isn't normal. Your check engine light comes on every couple of weeks with a code (P2459) indicating the regeneration isn't happening as it should, and you have to take it to the dealership for a manual cleaning and code reset. The dealership has confirmed this is a known problem affecting Ram diesel engines from 2018-2024 that hasn't been fixed despite years of complaints. Fixing this will likely require dealership service to manually regenerate the filter and update or replace components in the emissions system.

Your left turn signal is causing your high beams to turn on unexpectedly, even when your headlights are off or set to low beam. This happens regardless of whether you have auto headlights enabled or disabled, and doesn't occur when you use your right turn signal. The issue likely involves a wiring or electrical connection problem between the turn signal and headlight circuits that needs diagnostic repair.

Your steering column has an internal failure that's causing your turn signal to get stuck, which creates a safety hazard for you and other drivers. Your dealer is identifying this as an air bag clock spring problem, but existing safety recalls for your vehicle model don't cover your specific vehicle identification number. This issue involves your steering, exterior lighting, and air bag systems.

Your driver's side wheel center cap came off while driving on the highway under normal conditions. This is a safety concern because the cap can become a projectile that could damage other vehicles or cause an accident. The center cap will need to be replaced and the wheel assembly inspected to ensure it's secure.

Your 2024 Ram 3500 displayed a "Pre-heating Diesel" message on the dashboard when you tried to start it in cold weather, but no warning light came on. You took it to several dealers, but they couldn't diagnose or fix the problem, and there's no recall available for your vehicle's VIN. The issue started around 15,000 miles and may prevent your truck from starting properly in cold conditions.
