What owners report

Owners of the 2024 GMC Sierra 3500 most often describe transmission problems, including harsh or erratic shifting, slipping, and valve body failures that lead to power loss. Trailer brakes that cut out or show a warning while towing are also commonly reported, along with a tailgate that opens or lowers on its own, and some say recall repairs did not stop it. Where mileage is stated, complaints range from about 250 to 100,000 miles, and smaller groups describe electrical glitches, steering vibration, and brake rotor or pad overheating.

  1. Transmission and drivetrain

    Harsh shifting, slipping, and valve body failure

    • 12 complaints (24%)
    • median 49,500 mi at 1.5 yrs old (2 state mileage, few)
    • filed 2024–2026

    Owners describe hard or jerky shifts, a transmission that will not stay in gear, slipping, and a vibration or thump under load, sometimes with the transmission running hot. Several report a sudden loss of power or a loud pop, and dealers have diagnosed a transmission valve body failure, with repairs waiting on parts. According to complaints, some dealers found nothing wrong during inspection, while others found a valve body fault and waited for parts. Mileage is stated only in some of these complaints, at about 36,000 and 63,000 miles, and another describes harsh shifts since the truck was bought new.

    1 related service bulletin

    What to check: Ask whether any transmission recall or special coverage applies to this vehicle, and request repair orders for any transmission or valve body work. On a test drive, including a loaded trailer if possible, check for hard shifts, slipping, or a shudder under acceleration.

    2 excerpts from owner complaints in NHTSA records

    “Transmission has a bad vibration at low RPMs under acceleration as well as slipping and hard shifts. A few times the transmission has locked up the briefly. It also runs very hot between 180 and 249 degrees. Have been researching this when I came across all the problems and recalls however nothing listed for my VIN”

    NHTSA complaint #11655726, filed 2025-04

    “Since I purchased this truck in 2023 brand new as a 2024 the shifting has been very abrasive. It shifts far excessively harder than it should and I have brought this to the dealership’s attention many times. Now I am finding out that there is a massive recall on this vehicle’s transmission because of these issues that have been happening. The error codes are P0700 and P0747 The Engine and Transmission System is not performing as expected. …”

  2. Brakes

    Trailer brakes cut out or show warnings while towing

    • 8 complaints (16%)
    • median 11,195 mi at 1.2 yrs old (2 state mileage, few)
    • filed 2024–2026

    Owners describe the trailer brakes intermittently losing function while towing, with a warning message such as trailer brake disabled or service trailer brake. Some say the brake pedal had to be pressed to the floor to slow the truck at highway speed while towing, and others describe the in-cab brake controller not working with electric-over-hydraulic trailer brakes. According to complaints, a dealer replaced a rear plug without fixing the problem, a part for a related bulletin was not yet available, and some owners say the same trailers brake normally behind other tow vehicles. Where mileage is given, complaints range from about 2,390 to 20,000 miles, and the symptom is described while towing.

    1 related service bulletin

    What to check: Ask a dealer to test the trailer brake controller with the trailer connected, and ask whether a bulletin or part is available for the trailer brake message. Owners who tow should confirm that the trailer brakes respond to the in-cab controller and to a manual control before relying on them.

    2 excerpts from owner complaints in NHTSA records

    “The in cab brake controller does not work with electric over hydraulic trailer brakes. In my research to diagnose and fix the problem I find out GMC has known about this for years and has done nothing to correct. I pulled code C1114 and GMC issued a bulletin for part number (K58-036-00) which I purchased and still did not correct this issue. In short there are many 3500 trucks out there running with no trailer brakes. Here is the worst of this problem. …”

    NHTSA complaint #11589523, filed 2024-05

    “integrated trailer brake control system goes in and out of working order while towing either one of my trailers. one being a boat trailer and the other being a travel trailer. Have taken to local GMC dealer several times and they changed the rear plug the first time, which did not fix the issue. big safety concern if I can't stop my vehicle and what I am towing. Dealer claims it is most likely trailer issue but both these trailers brakes work perfect when towed with other truck. …”

  3. Body and structure

    Tailgate opens, lowers, or releases on its own

    • 6 complaints (12%)
    • median 40,600 mi at 2.9 yrs old (1 states mileage, few)
    • filed 2024–2026

    Owners describe the tailgate opening or lowering on its own, both while parked and while driving, and some report repeated events. Some say a tailgate recall did not cover their truck, others say the problem continued after recall repairs, and a complaint says recall parts were not yet available. According to complaints, unexpected tailgate movement has led to damage to a garage door and a trailer's propane tank housing. Mileage is stated only for a complaint at about 40,600 miles, and others describe events within a few months of purchase.

    Recall 24V894000Recall 24V0600001 related service bulletin

    What to check: Ask whether the tailgate recall applies to this VIN and whether the latch and release switch were checked after any recall repair. During a test drive or inspection, open and close the tailgate, and check that it latches fully and stays closed while driving.

    2 excerpts from owner complaints in NHTSA records

    “On at least 5 occasions, my inner tailgate has released itself and gone down during motion. This has been uncommanded. It appears GM has a recall for this but it does not include my truck. The dealership that looked into it agrees this is likely the same issue and GM should include it in the recall.”

    NHTSA complaint #11622341, filed 2024-10

    “Hello, I purchased my 2024 GMC 3500 AT4 Seirra late October 2023. Since the purchase date, I have been informed by motorist while at intersections my tailgate was down. I thought I was doing something wrong. On 3/3/2024 I was preparing to wash my truck and noticed my front amber lights were on surrounding my headlights. the vehicle was off, and my keys were in the house. Then my tailgate opener activated on at least 10 - 12 times. The tonneau cover is tight so the tailgate can need assistance opening. …”

    NHTSA complaint #11575496, filed 2024-03
  4. Electrical system

    Electrical glitches: gauges, computer, battery, shutdown

    • 9 complaints (18%)
    • median 48,000 mi at 3.0 yrs old (1 states mileage, few)
    • filed 2024–2026

    Owners describe the gauge cluster flickering or going blank while driving, climate controls flickering, and a computer failure that clears driver information and disables driver assistance until the battery is disconnected. Some report a battery that will not hold a charge or is low enough to need a jump start, and a vehicle that will not turn off or shows a shift-to-park message. According to complaints, control module faults, communication errors, and voltage-related faults returned after repairs, and a dealer could not reproduce some computer failures. Mileage is stated only in a complaint describing a warranty engine replacement at about 43,626 miles, and the other electrical complaints do not give mileage.

    1 related service bulletin

    What to check: Check that the gauge cluster, climate controls, and driver information display stay on and work normally during a test drive. Ask for repair records for battery, module, and computer work, and whether the dealer confirmed the fault or found no problem.

    2 excerpts from owner complaints in NHTSA records

    “Battery would not hold charge and would need jump start. Transmission would not stay in gear while towing trailer and would only go to 5th or 6th gear and would jerk out of gear and oil temperatures would go to 225 degrees. Erratically shifting and while driving with cruise control stop with out warning”

    NHTSA complaint #11662015, filed 2025-05

    “This 2024 GMC Sierra Heavy Duty has experienced a continuous pattern of major mechanical and electrical failures since early ownership. The vehicle required a complete engine replacement under warranty at approximately 43,626 miles. Since that time, the vehicle has continued to experience repeated injector failures, control module faults, communication errors, and voltage-related system issues. …”

  5. Steering

    Steering vibration, pull, and loss of power assist

    • 5 complaints (10%)
    • median 250 mi at 0.2 yrs old (1 states mileage, few)
    • filed 2023–2026

    Owners describe steering wheel vibration or oscillation at certain speeds, a wheel that is not centered or pulls to one side, and a sudden loss of power steering assist with a warning message. Some report a control arm bearing failure that led to loss of steering control at low speed, and a tire tread separation with a leaking steering gearbox. According to complaints, dealers rotated and aligned the tires several times and tried replacement hub parts without success. Where mileage is stated, these complaints range from about 250 to 21,000 miles, and an alignment problem is reported to return after about 100 miles.

    What to check: On a test drive, check the steering wheel at highway speed for vibration and confirm that the vehicle tracks straight without pulling. Ask for alignment and tire records, and whether the front hub, control arm, and steering gearbox were inspected.

    2 excerpts from owner complaints in NHTSA records

    “The vehicle has had steering and alignment issues since the day I purchased the truck. The steering wheel is not centered. The steering wheel is always turned to the left but the vehicle pulls to the right. I have had it at my local dealership five times and they have confirmed what I have described but they are not able to fix the issue fully. They have rotated the tires 3 times and have aligned it all five times. The vehicle will be good for about 100 miles and will go out of alignment again. …”

    NHTSA complaint #11560701, filed 2023-12

    “While operating my 2024 GMC Sierra EV Edition 1 at approximately 21,000 miles, a Service Power Steering warning appeared. Steering effort initially increased and then rapidly progressed to a near-complete loss of power steering assist. The steering wheel became extremely difficult to turn, making anything more than a gradual sweeping turn nearly impossible. I was able to safely exit the roadway into a parking lot. After shutting down and restarting the vehicle, steering assist returned to normal. …”

    NHTSA complaint #11767367, filed 2026-09

Buying note. Prospective buyers who tow should ask for a test drive with a trailer, and confirm that the trailer brakes, transmission shifts, and tailgate latch work normally. A pre-purchase inspection that checks for electrical or transmission fault codes, and records of any recall or special coverage work, can help clarify the truck's condition.

NHTSA complaint #11580555, filed 2024-04

Transmission and drivetrain: “Breaks and/or drive train. It is available for inspection. 1) Breaks sink causing slowed break time and decreased breaking ability. If the breaks are pumped , more often than not, they will come back up to full pedal. However, in an emergency breaking situation, there is not time to pump the breaks. I was nearly in an accident recently when the break pedal would not stop the truck in time, due to the soft break pedal. I literally had to steer to the shoulder of the road. …”

NHTSA complaint #11630713, filed 2024-12

Brakes: “I just bought my truck a 2024 GMC 3500 and in a few weeks after purchase. I took my truck in for a break vibration. I took the truck back in to find it had bluing on the rotors and the break pads have holes in them. I was told this came from over heating. They said it was missed on the pre sale inspection they did. I looked up info to see if this was a common problem and found the in 2022 GM changed the material to help with noise problems and this material had been know of premature break problems. The dealership denied doing the work under warranty. …”

NHTSA complaint #11680087, filed 2025-08

Engine: “Vehicle lost power, seemed to slip while pulling hills, Exhaust brake didn't seem to work. Dealer determined cause by DTC P209. Tested injector circuit, found loose terminal tension at injector number 6 connector. Replaced Cylinder # 6 injector connector. Did have multiple warning lights. Also submitting because Service Bulletin 23-NA+027 covered up to 2023. Believe it's an ongoing issue since vehicle is a 2024.”
