The vehicle was unable to exceed 10 MPH. The check engine warning light illuminated, and a dinging sound was heard following the incident. The vehicle shifted erratically, jumped gears, and made unusual noises. The contact associated the failure with NHTSA Campaign Number: 24V797000 (Power Train). The vehicle was towed to the dealer for diagnosis. The dealer confirmed an internal transmission failure and clutch lockup, with DTC P2732.

The failure mileage was approximately 107,000.

My rear spoiler roof area leaks. This is something GM knows about and has sent out memos to dealers. To fix this it’s around $1000. I think GM should fix a problem they have been well aware of for sometime.

A dealer "fixed" the P20EE code on this date, then the code came back a week later. Same dealer said they don't have qualified diesel technician, took vehicle to a 2nd dealer 9/22/2025, unable to determine cause of code. On 6/18/2026 same P20EE code came on again, took to dealer, dealer able to perform repairs on 7/30/2026 after ordering the correct parts. No on 9/23/2026 P20EE code is back.

While driving vehicle flashed engine power reduction signal and then the emergency brake automatic feature came on abruptly. Fortunately, I had been able to slow down after the reduced power, but if I wouldn't have quickly reacted to that, I think the emergency brake system would have caused a safety issue. Now. The vehicle is incapacitated. There were two recalls that describe this exact situation on the same year and model of truck, but my VIN number did not fall. Under that recall. The recall was for the sensor and then the second recall was because the first recall didn't correctly fix it. But the details of the faulty sensor are exactly what happened to my truck. So it sounds to me like they had more problems than just the recall that they acknowledged but they have not expanded it. My quest is to have them expand the recall to all of the vehicles that had the same problem.

When I try to start my truck it comes up as service trailer brake control module and it has caused my truck battery to drain so I cant even crank my truck up.

The contact owns a 2020 GMC Sierra 2500. The contact stated that the check engine warning light was illuminated, and the message "Reduced Power" was displayed.

The vehicle was taken to a retired GM mechanic, who diagnosed the vehicle with turbo charger failure. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 100,000.

While driving down a highway doing between 45 and 55 mph the transmission suddenly and completely faulted causing the truck to come to a complete stop. Just enough power to get to the shoulder luckily. The transmission had basically completely blown out, fluid everywhere. The insurance company did not find any comprehensive damage. The entire transmission needs to be replaced. There were no indicators showing any problems, no alerts, no warning whatsoever. Mechanics said there was a lot of metal coming out of the transmission. The truck is currently in a mechanic shop awaiting the new transmission, so at this time it is available for inspection. The safety issue here is that it happened on a busy highway, and the vehicle was no longer drivable so it needed to be towed causing more time spent on the side of the road.

A couple times I heard loud clanking coming from rear brakes. One time in particular I was trying to stop and it felt line someone had ran into my truck but must have been the rear wheel locking up

The main tailgate will not go down or function properly and it says online there is a national recall for this, but does not come up when I search my vehicle. When I turn on my left turn signal the brights flash for no reason and this is a known major issue with the vehicles as well. The trucks computer is telling me low on coolant even though it is not that has already been fixed through a 3rd pARTY WARRANTY Parking brake was stuck on when I bought the vehicle and had been for a long time you could tell and I had to pay over $1100 to fix it at GM. The Ford collision system does not work properly and the cameras will come on at certain times when they're not supposed to be and not come on when they are supposed to be

Bad vibration and bad wobble in steering wheel and front end components. This is the 3rd or 4th time my truck has been back to the dealer because of the same issue!

Catastrophic engine failure after taking it in for the April 2025 recall. Complete engine replacement needed

The rear defroster massively overheated. It started heavily smoking and eventually exploded the rear windows. Only warning sign was the smoke which we noticed quickly because the windows were up. Had the windows been down we might not have noticed before a fire started. I'm taking it to a dealership now. This module also triggers on from a remote start. Extremely dangerous!!!

Torque converter in my transmission we out, causing my gears to grind and lose power. Slight rumbling sound under the front passenger seat, First dealer (Palmen Motors, Kenosha WI) told me there was nothing wrong with the vehicle and no transmission error codes exist. Second dealer (Parks GMC, Greenville SC) indicated that i need a complete new transmission. Part is on backorder for the last 4 weeks and I am without my vehicle. No ETA for new part or any information on why it failed prematurely.

I have taken the vehicle to my local dealership six times. The tailgate started opening and the headlights were blinking on and off. This happened 3 months after I bought it. The dealership told me they changed the tailgate switch and they said there wasn’t anything wrong with my lights. Two weeks after the dealership said they changed the tailgate switch, the tailgate started opening and closing. The lights also stopped working driving down the road at night. This happened 3 different times at night. The tailgate opened when I was pulling a trailer and it caved in and I had to pay to have it repaired. The dealership said it wasn’t their problem. During this time the power steering fluid was leaking under my steering wheel and ruined my carpet. The dealership has yet to acknowledge that problem. I still have to put power steering fluid in the truck every week and my interior is ruined. The tailgate is still opening on its own. I had to start charging my batteries up every morning because they were dead. I got up one morning and the batteries were dead and the truck wouldn’t start. I had to buy a new $300 key. Took it back to the dealership for an appointment. The truck sat there for a week and I called for an update and they didn’t even remember the truck was there. It still sat there 4 days after that. They told me the truck needs new batteries and it wasn’t under warranty. I spent $1000 on 2 batteries. Tailgate is still going down. The lights are still going on and off. And

The catalytic converter failed at 93,000 miles, and 64 months. GM says it is out of warranty.

What component or system failed or malfunctioned, and is it available for inspection upon request? - Transmission Valve Body resulting in a P0700 & P0747 code. Yes currently installed in vehicle. How was your safety or the safety of others put at risk? - When the vehicle goes into a limp mode to protect the transmission and rear-wheel lock up, the truck shuttered and hard downshifted. Speed limit is restricted to 5th gear only. I've been instructed by GM to continue driving and using the vehicle until the problem happens again, knowingly putting myself and others at risk on a second failure that could happen at any time. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes this is a common problem with a recall #N242454440, NHTSA 24V-797. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Mine has been rejected by GM. Although I documented and photographed the failure codes, I cleared them from the vehicle in order to attempt to safely get to the dealer and prevent further damages. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? At the time of failure yes, check engine light and codes from an engine monitor coinciding with the known problems. Engine speed / power was reduced to allow only 5th gear.

After the transmission recall was completed, I’m now having erratic shifting. Having the recall adding software monitoring for a hardware issue is inadequate. Now that I am out of warrentee, gm has not resolved the issue and now I am having shifting problems.

Cracks in the rear sliding window plastic upper rail glass guide causing Rear window leaking water and causing mold from water leaking. GMC has a service bulletin number 18-NA-383 knowing of this issue and not telling customers purchasing the GMC vehicle. The service bulletin was released in 2019 before purchasing the truck and they still didn't inform the customers. My child rides in the back in a car seat and now has been breathing in this mold and mildew for how long. I have had my vehicle in with Titus will Gmc in olympia multiple times for service and inspection of various recalls and still didn't inform me of this issue.

While towing my dump trailer early in the morning for about 20 minutes I noticed sudden hard up shifting and down shifting in some gears on flat surface roads. I then proceeded to approach an incline hill about a 5% grade and then, what I've recently learned, my transmission locked up and released for a split second. The roads were slick so it didn't seem too harsh, I continued with no incident for another 40 miles and then it happened again while pulling up a 7% grade in a left hand sharp turn at 40 mph. The truck fish tailed and jack knifed my trailer on the left rear side of my truck and the front left side of the trailer. I was on a one lane road and had to continue until I reached my detitanation, I slowed and maintained a speed of 45 in order to prevent it from happening again but it did it 5 more times before reaching my destination. I'm currently scheduled to have the transmission checked on 02/27/2025 at Peterson's Chevrolet Nampa Idaho. In the meantime, I have no means of using any of my trailers.

Well, we ended up having a problem with our transmission in our 2020 truck. I am the wife and I was driving down the highway and all of a sudden the truck started bucking and went down to 35 mph. I was in a middle lane on the highway when this happened which Was very scary! Then I was stranded along side the highway until I could get help. Here we found that our transmission went out already only after four years, which is crazy. Very crazy! We bought this truck because we were told with the weight of this truck and all that it would pull out 42 foot fifth wheel we have. So of course we did use this truck to pull our trailer and now four years later we have been without a truck because we cannot even find a transmission with our transmission code of OMEF. Now today we found a possibility which is going to cost $7000 which is Love Ludacris! We buy a $65,000 truck just for years ago and now had to put $7000 out for a transmission. Is there anything we can do to rectify this situation??

My vehicle inadvertently locks the rear tires at highway speeds and then releases and drives. In some instances it may brake several times causing the tires to burn rubber for a short distance causing rear traffic to either swerve to avoid rear ending me and in a couple instances causes the rear following traffic to abruptly change lanes to avoid rear ending me

Tailgate fell down when I had a trailer hooked up. I was parked, then backed up the trailer. Tailgate came down on the jack and scratched the tailgate. There is a recall on some trucks but mine says no recall. Sounds like same issue.

I was travelling south bound on the highway at 70 mph when out of no where the left rear tire failed. The tread peeled back like an alligator skin and tore apart the side of my truck and caused me to fishtail all over the highway. I was able to avoid colliding with other vehicles on the road and miraculously made it to the shoulder of the highway. The tire is a Goodyear Wrangler TrailRunner AT in a size LT275/65/R20. I still have the remaining parts of the tire. My vehicle is still under manufacturer warranty, but the GMC dealer turned me away and told me I had to deal with Goodyear directly. I reached out to Goodyear to file a claim for the tire failure and damages related to it. They have been ignoring me for over a week, so I have filed a claim with my insurance company to handle the damages. I'm currently waiting to get my truck into the shop for repairs. There were no indications of any issues with the tire. I had them rotated as recommended by the manufacturer and kept the tire pressure at the recommended levels through the dealer when my vehicle was serviced. The TPMS light came on as soon as the tire failed and lost pressure showing the vehicle tire pressure monitoring system was working properly when the tire failed.
