A large trim piece at the top of my grill flew off while driving 70+ on the highway. I have personally seen roughly 100 testimonies with picture proof on various fb pages of others with the same vehicle experiencing the same thing. This is a known issue for the 2022-2023 model years, GM has apparently corrected the issue for the 24+ model years.

I was driving down the highway at 65 when the upper front hood molding flew off and bounced off my windshield. There were motorcycles behind me but none were hit. After researching on [XXX], many others have had the same thing happen. This could have broken my windshield, or worse, hit a motorcyclist behind me causing a wreck. It has not been inspected but reported by many others on GMC forums. There was no warning whatsoever. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While commuting on a US Hwy the front upper grill came off the vehicle flying into the windshield and surrounding traffic. Research online shows that this occurrence happens with the same vehicle with different owners. This is a life safety issue that also is not being repaired by the manufacturer.

When traveling out of town on the interstate approximately 70/75mph. Part of our hood/trimming deluged scraping our hood and nearly Colliding with two other vehicles. Not something that is common and seems to me a manufacture defect that GM is trying to wipe their hands of and I will not stand for that. I have been trying for about a month to get GM to repair this odd phenomenon. However they continue to give me the complete run around. It-??s been absolutely impossible to get a hold of anybody the dealership will not help me. I keep receiving email from Gm saying they attempted to make contact but, I did not answer my phone. I have my phone on me at all times I have received no voicemails from them. I write and called them back. I haven-??t received a return call/voicemails, or email. GM originally refer me back to the dealership when the dealership will not help me. They originally said they will order the part. I have to pay for the part and they will pay for labor. They contacted me when they had the part in hand supposedly. I sat at the dealership for three hours today for them to tell me that part was not correct and that they can-??t cover it and that I would need to cover it, I am tired of the games and I want my vehicle fixed. I have been left with no choice but to file complaint.

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.

While unlocked, passenger doors go through unlocking phase, door locks click, parking lights flash and tail gate comes open. Along with this, an electric motor sound comes from underneath the vehicle (pre start fuel pressurization sequence?) that goes on and on, doors locked, or unlocked, that, left unchecked, drains the battery. Must be hooked to battery recharger round the clock.

I purchase my 2022 Denali 1500 crew cab Brand New. After a few weeks of ownership. My mulitpro tailgate would open on its own. I had taken my truck to the nearest Gmc dealer to have it looked at. They said they could not find anything wrong with it. A few month later the exact thing happen to me with my wife in the truck. Again i'm back at the dealer and they could not detect the problem. So i left and headed home. I had to take a trip to Pennsylvania and after driving with my enclosed car hauler attach. The tailgate drop open striking my trailer level wheel, putting a dent in my tailgate/ Took it back to Gmc in Alcoa Tn and again no issue or fix was provider. Still Having issues with my Multipro Tailgate opening on its own.

Tailgate occasionally self deploys. 1 incident resulted in damage to the tailgate while towing a trailer.

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.

Vehicle does not have a notification via chime or message stating the rear tailgate is open. 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. This can lead to serious injury or to any vehicle behind it. Many owners have already reported losing cargo such as tool boxes, paint cans and groceries spilling throughout intersections.
