2024 Chevrolet Silverado 3500 Problems

What owners report

Owners of this model year most often describe trailer brakes that disconnect or show a disabled message, some involving RV or camper setups with solar charging. Transmission valve body and shifting faults, sometimes causing limp mode while towing, come next, and some complaints describe engine oil cooler failures. Because this model year is recent, mileage data is limited and the pattern over time is not yet clear.

   Trailer brakes disconnect or show a disabled warning

   • 20 complaints (39%)
   • median 1,650 mi at 0.4 yrs old (4 state mileage, few)
   • filed 2023–2026

   Owners describe trailer brakes that stop working intermittently while towing, with messages such as Check Trailer Wiring, Brakes Disconnected or Trailer Brakes Disabled appearing on the dash. Some say the trailer brakes came back after a stop or restart, and others say the trailer did not slow as expected when the brake pedal was pressed. Some complaints describe RV or camper setups with solar charging, where the brake controller stops connecting to the trailer brakes, and some say the dealer replaced the brake controller without ending the warning. Where mileage is recorded, these reports fall between 200 and 12,000 miles, and the messages appeared while braking or towing at various speeds.

   1 related service bulletin

   What to check: Ask whether the trailer brake controller or brake module was replaced or reprogrammed for these messages, and check for trailer wiring or brake warnings during a test tow if possible. Ask whether the electric trailer brake diagnostic bulletin was followed, and whether any brake module recall work has been completed.

   “Recently purchased a 2024 Chevrolet Silverado Hd3500 and use it to haul a 40' 5th wheel toyhauler. Several instances when I connected the RV electrical cord to the truck I would see a check trailer wiring message. Along with this message I noticed there was no current going to the RV brakes. I had several technicians look into matter, but could not find a resolution. Later my brother sent me a YouTube related to this problem. …”

   “Trailer brakes and lights come and go. I start with having everything then loose brakes and lights when I’m driving. This is apparently a known issue that they have a fix for but I have never received anything about a recall.”

   Transmission and drivetrain

   Transmission valve body and shifting faults

   • 10 complaints (20%)
   • median 19,000 mi at 1.2 yrs old (1 states mileage, few)
   • filed 2024–2026

   Owners describe transmission valve body failures, hard or erratic shifts, and reduced acceleration. Some reports describe the truck entering limp mode or being limited to low speed, including on a freeway while towing. Complaints say replacement valve body parts had long lead times, and a complaint says a software update did not address the valve body problem. Mileage is not listed in these reports, but some describe the problem beginning while towing a trailer, fifth wheel or camper.

   What to check: Ask for fault codes and repair records for the transmission, and check for stored valve body or shift codes during a pre-purchase inspection. On a test drive, check for hard or erratic shifts and any reduced-power warning, and ask whether a valve body repair or software update has been documented.

   “The valve body failed on my transmission. My safety was impacted because as I was towing my 40 foot camper and my vehicle went into limp mode on the freeway at 70 miles an hour and I could only go 45 with four children in the vehicle. Yes the problem has been confirmed by a local dealership. There was a check engine light present, but eventually it went away and the truck returned to normal. This has happened one time before as well.”

   NHTSA complaint #11640471, filed 2025-02

   “REAR WHEEL LOCKUP: While driving down the highway pulling a loaded trailer the rear wheels locked up, GM has an open recall on 2020-2022 models but denies its an issue with the 2024 model, my dealership pushed a “software update” but that does not fix the faulty transmission valve body issue, it just overrides the safety features that were designed to protect the transmission. I have a video of it occurring while slowing down for a stop sign when it did it the second time to me.”

   Body and structure

   Vibration or humming from wheels and rear axle

   • 5 complaints (10%)
   • median 13,000 mi at 1.1 yrs old (1 states mileage, few)
   • filed 2024–2026

   Owners describe vibration felt in the steering wheel and seats at highway speed, a loud humming at highway speed, and a chunking noise from the rear of the truck. A complaint links the vibration to front hub bearing parts, and another says rear-end bearings were damaged enough that the rear end needed replacement. A chunking noise was addressed by re-torquing leaf spring joints, and the owner says the joints can come loose while driving. Mileage is recorded for only a few of these reports, including one at 13,000 miles, and some describe the noise or vibration at highway speed.

   What to check: Drive the truck at highway speed and note any vibration in the steering wheel or seat or any humming from the rear axle, and check hub and wheel bearings for play. Ask whether the front hub bearings and rear axle bearings have been inspected or replaced, and whether any leaf spring joint work was documented.

   “Vibration occurs when driving at highway speed. Vibration can be felt in the steering wheel, drivers seat, and passenger seat. I believe this is related to my vechicles front hub bearing extensions. there was a TSB for this issue on presious model trucks and the same part is used on 2024 models.”

   NHTSA complaint #11609529, filed 2024-08

   “Vehicle was making a very loud humming noise at 73 mph. After returning to the dealership they found that the bearings in the rear end house had destroyed themselves causing internal damage to the housing and the entire rear end now needs to be replaced.”

   Engine

   Sudden stalls and loss of power

   Mentioned in 4 of 48 sampled complaints

   Owners describe the engine or power suddenly cutting out or losing power while driving, with warning codes and, in some reports, reduced steering or brake assist. A report describes stalling while hauling a trailer on the highway after a high-pressure fuel pump had been replaced. Another complaint describes a truck that would not drive after the diesel exhaust fluid heater stopped working and the tank froze. Mileage is recorded for only a few of these reports, including one at 19,000 miles, and some happened while towing a trailer or fifth wheel.

   What to check: Ask whether any engine, fuel pump or diesel exhaust fluid heater repairs were done, and scan for stored codes during a pre-purchase inspection. If possible, test the truck while towing a trailer to check for hesitation or warning messages.

   “I believe my def heater has stopped working and my full def tank is now frozen. I’m now stranded in the middle of South Dakota in -29 degree weather. My truck will not drive. Or idle for the heater to keep me warm because the def is required for engine to run.”

   NHTSA complaint #11565082, filed 2024-01

   “I was towing my 36 ft 5th wheel home from my storage place when the engine stopped. I had no brakes or power steering. I was coming up to a stop sign when this occurred so fortunately I was only moving about 15 mph. I was able to stop the truck and trailer by using the 5th wheel braking system without any damage to vehicle or other property. Once I regained my composure I tried to start the truck. All the dash lights were on but it would not start. The digital display kept showing Service ECM & Service StabiliTrak. …”

   NHTSA complaint #11582079, filed 2024-04

Buying note. Ask whether any trailer brake controller, brake module or transmission valve body work has been done, and whether the truck has been tested while towing. Before buying, confirm that the recall work for the tailgate latch and steering gear shaft has been completed.
