ELECTRICAL SYSTEM, EXTERIOR LIGHTING, SERVICE BRAKES
This vehicle exhibits the same failure described in NHTSA Recall N232426400 — spontaneous unlatching after rain due to water intrusion into the exterior tailgate release switch. I’m requesting a goodwill replacement under GM bulletin # N232426400 as the failure mechanism and part are identical. It has caused brake failure and nearly killed me because of battery drain while driving. All American Chevrolet of Midland Texas is refusing to solve the problem and says no recall is available.

ENGINE
Pulled up to a stop sign, the engine shutoff and would not restart. Had the vehicle towed to the dealership. Received a call that the engine will need to be replaced. The code is a P0016. Same code as the other 6.2 L87 GM motors, but is not currently under the recall. They found no metal in the oil pan and the engine only has compression on cylinders 2 & 8. Make no mechanical sense. Before this, I had no engine lights, I had no oil burning, I had no smell of oil and the truck ran fine. No loss of power or any other issues.

STRUCTURE:BODY
The accident occurred when the tailgate opened without warning or any buttons being pushed while towing a boat trailer. The tailgate become bound between the truck and trailer. The tailgate was damaged and limited my ability to turn the truck. My truck is normally parked in a garage and doesn’t sit in the weather. This truck is my 3rd vehicle so it doesn’t really get driven unless it is pulling a trailer, I tow with it all the time but very rarely use the bed or tailgate. Monday June 16 – Drove from Gallatin, Tn – Eddyville, Ky – Paducah, Ky the weather was constantly heavy rain and wind. Tuesday June 17 – Drove from Paducah, Ky to Defeated, TN more of the same bad storm. There were 3 of us and no one opened the tailgate, we hooked up to my boat and drove less than a quarter mile to the boat ramp, when we arrived, the tailgate had opened and the stairs on the boat had impacted the small part of the tailgate during a right turn. Prior to leaving the driveway and after hooking up the boat I had to back up slightly and remove pressure to remove the chock block from the boat trailer tires. (I would have noticed that the tailgate was open) this happened with no warning, put me and my passengers at risk and did over $1000 dollars in property damage. I was expecting GM to replace the parts that were faulty and the small part of the tailgate that was damaged. I returned twice to Larry Stovesand GMC and had them access the switch. They have refused to supply paperwork from those visits and have become dismissive and deceptive. The contact there is Craig Morgan [email protected]

ELECTRICAL SYSTEM
The vehicle will loose all interior audio to include stereo, turn signals, and all other audio safety features for several hours at a time. GMC has done three repairs and still no resolution. Lack on audio impacts the safety of the vehicle. Has happened dozens of times and appears to be larger GM issue that is u resolved. Has occurred at least 20 times since I bought the vehicle 10 months ago.

ENGINE
After having transmission issues which was replaced under warranty, within 300 miles, the engine failed. The vehicle has now been sitting at the dealership since October 7, 2025 waiting for a replacement engine. There is no timeline available for the replacement engine as they are currently backordered. Absolutely ridiculous.

ENGINE
I noticed a ticking sound in my 2020 GMC Sierra 1500 SLT 5.3 Liter on 10/15/2025 after it was serviced at an Authorize Buick GMC Dealership on 10/13/2025. I made an appointment and returned the vehicle to the dealership for further inspection on 10/17/2025. I was informed later that day that my truck has lifters and camshaft failure. If my truck had stalled or stopped on the express way, myself and others safety could have been at risk. My truck has only been looked at by the dealership at this time, and it is available for inspection upon request. There were no warning lights, check engine lights, messages or symptoms prior to the failure. I did get a low oil level message in April 2024 when the dealership stated they must not have put the correct amount of oil in my truck during an oil change on 1/29/2024. They inspected my truck and assured me there was no damage done to my Engine from this issue. I have recently learned there is a recall for GM Vehicles manufactured between 2021 and 2024 with the 6.2L engine installed. I am not sure why this recall does not include 2020 trucks with the 5.3L engines installed. Apparently, the same problems exist with these engines also. I received an estimate for repair approximately $13,000 which can increase once the engine is town down and inspected further. Any assistance you can provide would be greatly appreciated.

ENGINE, VEHICLE SPEED CONTROL
The first time the truck stopped and wouldn’t want to start (engine light came up) after a few minutes and with a push the truck turned on. Next day while driving on freeway the truck shift hard pulling vehicle back as if it was going to stop without braking. Took truck to GMC dealer on 9/26/25 for an inspection with approx 17,000 miles. Oct. 17, 2025 GMC rep said my truck was inspected/ good to go and was ready for pick up. Not sure what part they had replaced. On Oct. 18, 2025 picked up truck while leaving dealer I had my family in my truck about 3 miles into my drive we heard a loud clunk and the truck shifted hard slowing the truck down and display reduce acceleration drive with care and check engine light on. Have in mind we were on a busy traffic street driving while other cars had to pass us because we couldn’t speed up. I did not feel safe with my children in the car, left it again for the 2nd time with GMC service dept. Now we are almost reaching to a 30 day grace period without our vehicle.

POWER TRAIN, VEHICLE SPEED CONTROL, ENGINE
I just took my 2021 GMC Sierra 1503.0 Duramax diesel into Faulkner Nissan, today 10/18/2025 m, to have that recall fixed. I picked it up from the dealership and drove about 10 miles before it went into limp mode and reduced power mode while I was driving and started to shift very roughly and I’ve never had any issue like this before they supposedly fix this recall, I think the software patch made it worse in my case. Now my vehicle is throwing a bunch of different transmission error codes, that it has never produced , and it is going into reduced power mode,as I’m driving and going into limp mode as I’m driving, which you never has done before And it feels like it’s stuttering in early gears now and the idle was really rough it didn’t idle at a specific spot it went from 800 to 1300 back down to 800 when it should’ve just been idle at 800. I don’t know what to do. It seems like this recall made the problem worse for me and my truck in this case, I don’t know what to do and I don’t know where to go. I hope you guys can help us. Please make GMC take responsibility Before somebody gets killed. If they haven’t already this issue is extremely DANGEROUS AND I’M SURE IS DESTROYING THE TRANSMISSION. I don’t feel comfortable driving my family in my vehicle anymore because of this issue it is terrifying….

POWER TRAIN, ENGINE, UNKNOWN OR OTHER
I was driving at highway speeds probably doing 55 and another vehicle pulled out in front of me forcing me to slow down rapidly. That’s when my wheels locked up and my vehicles wheels locked up in the middle of the highway. Screeching tires, almost like the vehicle went into park for a second. After about two seconds, I was able to continue driving a highway speed no check engine lights no error codes. It felt like I just hit something nearly gave me a heart attack. My family was in the car. It felt like we all almost died. It was terrifying. This transmission issue recall situation has happened to me more times than I can count. Now it’s almost a guarantee that if you have to shift too hard too fast it locks up the differential and it is terrifying. Every time.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
This was the first time I had ever experienced the rear differential locking up at highway speeds in my truck. It was probably the day after I bought the truck. I was going down route one southbound going probably around 60 miles an hour and the wheels locked up and the vehicle felt like it was gonna come to a screeching hole. It felt like I hit something And then the wheels unlocked and it allowed me to keep driving. I thought that I might have hit the cruise control button on the steering wheel by accident and chopped it up to operator error which now I know is one of the most dangerous recall issues I’ve ever had to experience or indoor. Thank goodness my family was not with me at the time. But these issues continued on for months…
