Tailgate randomly opened while in park. This is a problem for multiple reasons. When hauling a travel trailer when you put the truck in park the tailgate falls into the jack denting the tailgate and scratching the paint. On some trailers it would be possible for the tailgate to fall onto the jack switches causing the jack to go down unexpectedly. The only way to get the trailer off is not put the truck in Park which isn’t safe at all! The truck rolls in neutral if the parking brake isn’t on. You should be able to put the truck in park and not worry about the tailgate. I called GM a few months ago when this first happened and then it stopped until it rained this weekend while camping. I told them at the time I didn’t want it falling when I started hauling the camper. They said at the time that a dealer would have to look at it and did say there isn’t a recall on this truck like on the HD trucks so is essence I basically have to hope it does it while at the dealership so they will believe me as my word doesn’t mean anything. In my case after the switch is dry it doesn’t do it. Now I have video recording as it is memorial day and pretty hard to get it into the dealer when they are closed just to have it with fine there.

Multifunction tail gate opens while driving, opens when going over speed bumps, opens going over small bumps and opens while driving down the highway. I brought the vehicle to the GMC dealer, they replaced an electrical switch on the tail gate. This did not fix the problem, I called the dealer and they told me GMC does not have a repair for this new issue. This is a brand new truck that is under factory warrant, the truck has 10000 miles on it. If I ever have a load in the bed it may fall out onto the road or highway.

On January 20th 2024 I was cleaning heavy dirt and mud off of my truck, after leaving the car wash and driving about 20 miles, once I parked my tailgate started to open over and over on its own. This happened again on March 4th 2024 after cleaning off a lot of dirt from my vehicle the tailgate opened on its own while my truck was parked in the garage. It opened into the garage door, when I left I did not know it was open, so when I opened the garage door the hinges on the garage door scraped and dented the tailgate as it opened. I had not pressed any buttons inside the truck, outside of the truck, or pressed the tailgate open buttons on the key fob. After intense car washes it has opened on its own each time.

On Feb. 27, 2024 approx. 04:15 left for gym and work. When arrived at gym and began to park, I put truck in reverse to check back line and noticed I was looking at my license plate. I then put into park and got out of truck and shut tailgate. Thinking not much about it, I must've touched the button the night before and hit a bump on way into work. Since I have a toneau cover, it fits pretty tight and I typically have to pull it down by hand. I heard about recall that day after I got to work from co workers. Checked my VIN, but did not come up as one of the tailgate recalls. March 7, 2024- Left again for gym and work approximately same time in AM. As I was driving into gym and work, another car coming up close behind me wanted to pass. The car then suddenly backed off to a considerable distance. As I got to gym and put in reverse to check my back line, I noticed I was looking at my license plate again. I know that I did not touch a button either on FAB or tailgate. because I park in garage and leave FAB in a secure place where it can not be pressed. If tailgate was down in my garage, it would have stopped garage door from opening and/or damaged my garage door. In either instances, I did not get a sensor alarm going off on my dash for "tailgate down", If its even equipped with that alarm.

Tailgate inadvertently opens. There is no visual or audible alarm to inform me the rear tailgate is open. This is a Denali package truck. I have lost items, coolers, small folding tables among small items without warning. Most of the time I was traveling on a highway. Could cause accidents, injury to others as well as I have lost my belongings. I have had the dealership as well as 2 requests with GM customer service with no corrective results. The trucks tailgate will show an open display warning but only when top tailgate is down/open. If the whole tailgate is down/open there is no visual warning on dash. I believe there was an error in placement of open tailgate sensor when truck was produced. 2023 models have correct sensor placement and visual dash warning. The 2022 was a new redesign doe the Sierra class truck and there was a mistake where the open tailgate sensor was placed. I went to GMC virtual site and the 2023 model examined by GMC employee on visual check shows on complete tail gate down/open the same dash visual tail gate open alarm I see on my 2022 when only the top part of whole tailgate is open. My Dealership and GMC customer service have been involved for the past year. I have been reimbursed by GMC for my losses but problem still exists.

There is a button on the dash that can open the tailgate when the vehicle is stopped at an intersection, this can be inadvertently pressed without the driver knowing, causing the vehicle to drop any cargo when accelerating or leaving the intersection.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure.
