GMC has a problem with the electronic brake controller on their 2024 Sierra 2500hd and 3500hd trucks. All trailers are required to have trailer brakes. In addition the trailer must be equipped with an auxillary battery to activate the emergency breakaway brakes. If the voltage on this battery is higher than the towing vehicle battery, the vehicle controller can display a trailer wiring fault display. When this happens there are no brakes on the trailer. This fault happens intermittantly and can last between 10 seconds to 30 seconds. We constantly have this problem with our vehicle. On two occasions we were in an emergency situation towing a12,500 lb load and had no brakes. This is a severe safety concern. The GMC dealer stated that the problem is because our trailer uses a regular car battery to work the hydraulics and the brakes. They stated that the controller pings the trailer to see is anything is connected and that the car battery can interfear with this signal. When this signal does not return the controller senses that no trailer is connected and disables the trailer brakes. The trailer that we have is new and it is wired according to industry standards. Thre are thousands of trailers on the road that have this configuratiion. We have inspected the trailer and cannot find wiring problems. We have towed the same tyrailer with two different trucks and do not have this problem. A quick search on the internet will reveal that many other people are experiencing the same problem.

[xxx]: after arriving home and parking in my driveway (plugged in the block heater that came installed from the factory), approximately 35 minutes later my neighbor rang the doorbell. She was yelling that my truck was on fire! the flames were starting to hit my eaves on my house. I put the fire out with my hose. The sparks fire department had to pry open my hood to disconnect the batteries in order to stop the truck from lighting back on fire. The vehicle has been inspected by general motors and turned over to their insurance. My insurance has also inspected the vehicle and stated they believe that the wiring to the block heater was faulty. There were no warning lamps, messages or other symptoms of the problem. This truck has 19,000 miles and is 1. 5 years old (2022). How could this be turned over to gm's insurance and not under warranty? I have not had my truck for over 2 months now. I wonder how many of these trucks are lighting on fire? the truck is currently at the local dealership and is available for inspection. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Upon starting our 2024 GMC Sierra 2500hd after towing a camping trailer for approximately 200 miles, the following error notifications would cycle every 20 seconds to 5 minutes: "check trailer wiring" "service trailer brake system" the trailer brake would become disabled after these errors, and sometimes would connect with a "trailer brake connected" message, only to repeat every 20 seconds to a few minutes later. During the 60 minutes in which I drove to an RV dealership to have the problem looked at, on multiple occasions, I had no trailer brakes when braking, or had no trailer brakes until the trailer brakes suddenly connected at below the speed of 35 - 25 mph. Gm has acknowledged document 6420021 and bulletin #23-na-149 that this could happen when pulling a trailer with a battery, generator, or solar charger that has a higher state of charge than the vehicle battery. This is an extremely unsafe condition that could easily cause a rear-end accident or a jackknife condition of the vehicle/trailer combination. Gm has known about this issue since at least June of 2023, and as of September, they have an updated trailer brake controller that is supposed to correct this issue. There should be an immediate recall of the vehicles involved to have the trailer brake module replaced with the updated part.

I was driving and the transmission control module failed, putting the truck into limp mode with no prior warning. This was a hazard to myself and other drivers as it happened on a very busy road. I use this truck to pull our fifth wheel camper and luckily we were not pulling the camper at that time or this could’ve been a lot worse with the truck just stalling putting my families safety at risk and being broke down in the middle of nowhere. I took the truck to a repair shop in the city that I live in and it was confirmed that the tcm was bad. Tried to order a new tcm and they are back ordered for months and even over a year. Had to send it into a company in south carolina for repair of the tcm with a cost of approximately $1300. There are thousands of people with this issue, and this should’ve been addressed by gm and a recall sent out to the owners of the vehicles. After the truck went into limp mode, there was a error message but no other prior warning.

My 2007. 5 GMC duramax has been parked for 1 month, had to barrow a truck to go to work, just not willing to pay the 1600-4500 dollars that suppliers or private sellers are asking for the tcm, tried a private seller on ebay and it turned out to be a scam, local dealership has no clue on eta, I use my truck 6 days out of the week and now sitting not being moved may cause other issue when I do finally get it going again, the problem with my durumax is the tcm transmission control module, I was already at home when issue started.

Service trailer brake system warning will not stop dinging and alerting. This happens constantly with or without a trailer . I dismiss the alert and it continues to sound off. I have trouble thinking or talking. Very very distracting. Took my vehicle to the dealer and they did not know how to fix it.

Driving at 70mph, thread from tire blew. . That was in July, I went and purchased another tire from bob king GMC wilmington, nc. The first tire that blew was now discontinued so I purchased another good year . On Friday I noticed that another tire on my truck had a bubble along the threads again. It was also getting ready to blow like the first tire. I went to the dealer and they told me the tire I purchased (good year) was also discontinued. . . Please look into this matter. . They have faulty tires and this matter could have turned out with a death. . It isn't the dealers fault it is good year . . . . I have also read on line this isn't the first time people are complaining about the threads coming apart. . . .

The tcm failed while my husband was driving the pick up and this also set off the posi traction control and stabilization link. The truck has fluctuating shifting and could have cause a wreck if there had been someone behind him because the speed dropped on the tuck and it the transmission can't shift properly or consistently for safe driving. The part has been on nationwide backorder for over a year. . This truck can not function properly with out this part. Calling the dealership there are many vehicles affected with this problem and no estimates time of part arrival replacement. The dealership knew exactly what the problem was when called but didn't recommend dropping the truck off as there are no eta on replacement. Their recommendations is to research online to try to have the part repaired. No the part has not been inspected as it it unsafe to drive at the moment and there are no available replacement parts for the tcm at this time. The warning lights did not come on until the part failed to allow the transmission to shift. Per some people on a face book group this has apparently been a known issue with this part since 2011.

Rear sliding window leak and has saturated seat and carpet causing an unhealthy environment. Spoke with dealer and was told it is a design flaw and repairs are not covered under extended warranty. I was also told it is only a temporary fix and “ leak will reoccur”. I only realized of the problem when soap residue was seen on the inside of the widow. Dealer gave estimate of repair.

When towing a trailer a notice to service trailer brakes comes on and the trailer brakes are disabled.

The contact owns a 2019 GMC Sierra 2500. The contact received notification of NHTSA campaign number: 21v496000 (equipment); however, the part to do the recall repair was not yet available. The dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

No incident as of yet. The wide angle driver mirror cannot be set high enough to see down the side of the truck. It is a factory installed towing mirror. I have to lower my my seat all of the way and I cannot see the top rail of the bed. The mirror won't let me see down the side of the truck which makes it really dangerous when I pull my 32' fifth wheel trailer. I took it to the dealer and they told me at first ( I purchased the truck on 01-22-2023) the mirror is one of 6 items that warranty doesn't cover. Then they told me it is very difficult to get the manufacturer to authorize replacement. The dealer eye balled a mirror just from standing in front of it on a lot truck and said he couldn't see a difference. All I can see out of it is basically is the rear tire. I called gm and the person looking into it was transferred after about a week. The person that took over asked me to give him a week to look into it. He called me today and said he hasn't had a chance yet that he needs a couple of more days.

The radio in my truck acts on its own (buttons push by themselves). The problem is known and I’m fine with turning my radio off instead of paying a lot of money for a new one. I’ve been fine with it until recently. First problem I’ve let go for a while now which is that it turns on by itself while driving which is a distraction. But biggest problem now is not only did the radio turn on by itself but it also went into the backseat reminder and turned it off. I do have an infant and I hope to never forget. But when paying for a vehicle this is a feature you pay for. No one should lose a child bc of this. I’ve talk to a dealership about the initial problem and have done research on it. There is no warning signs. Vehicle has not been inspected by any others. I do have a video of the backseat reminder turning off without my control.

I have a 2018 GMC sierra duramax quad-cab and when it is connected to either my boat, stock trailer, or cargo trailer the lights and electric trailer brakes on the trailers do not work. And the chime from the "service trailer brake" indicator sounds and doesn't stop until I unplug my trailer harness from my truck making it a distraction and an unsafe situation when trying to navigate through traffic(changing lanes, stopping, and other functions needed when hauling trailers). The dealership said it was a module and specified which one and so I elected to replace it myself and it wasn't the issue. I choose to do the work myself as they quoted me a price of $700. 00+ to repair the problem.

1. The engine block heater sparked and created a small flash underneath the truck. It can be inspected whenever you would like. 2. Electric spark/fire 3. The problem has not been reproduced nor inspected by the dealer. I would not dare to plug it back in. 4. There were not any warning messages. It happened the first time the engine block heater was plugged in. February of 2022.

Water leak, known in other years of the same model vehicle, caused the rear defrost to fail and smoke when in operation nearly causing a fire in the vehicle as it was being operated.

Dash board is cracking in various places even after being repaired. Concerned that it could disintegrate sending plastic pieces flying in an accident or air bag deployment.

Hit in the driver side tire, air bags didn’t release. Truck then went up in flames.

Dash is cracked in multiple places. Dash is not structural however loose shards of plastic pose a serious safety hazard if they were to come loose as a the result of a sudden change in acceleration. Vehicle is low milage with 130k miles, previous owner failed to report or repair the failed dash prior to my ownership. It is a common failure on gm vehicles however it is very expensive to repair, unwarranted, yet poses a serious safety hazard. Dash will need to be repaired to ensure the safety of me and my family.

Def emission system failure. Total component breakdown requiring replacement. Parts unavailable.

I auto started my truck. We jumped in and I put the key in to start and turned down the heater and pushed the rear defroster off and the passenger side rear window blows up like a shot gun blast. It shaders into a million pieces. Our 2 year old in a car seat right in front of it rear facing. If I was driving with the amount of noise it produced I could of crashed. I see there is a bandage recall but not for the hundred of thousand of the 2014/2020 for back windows just blow out.
