Body problems of the 2022 GMC Sierra 1500 - part 2

While driving down the highway, then without any warning the front upper lip of truck grille flew off randomly. The broken piece shattered windshield and caused damage to body of vehicle. Reported to dealer, but they said I must have hit something to cause the damage. I did not hit anything. I was simply driving down the highway. This was a failure of the truck.

While driving home from work, on the highway. Travelling 68 mph. The upper moulding on the front grille blew off, struck my windshield and landed on the highway behind me. Vehicles behind me had to swerve and slow as a result. I waited for a safe time to pull over and turn around to go back and retrieve the piece. Once retrieved, I could see the plastic clips had broken. Some are still missing. Wry dangerous situation, luckily it was not dark outside, otherwise I imagine other vehicles behind me may not have seen it, could have caused a bad accident.

Upper trim piece of grill broke off while traveling down roar at 60mph. Part struck my windshield and flew over cab of vehicle and impacted the vehicle traveling behind me. Could've caused a much more serious accident!.

Upper trim on front grille fly off while driving. All clips were broken, very thin plastic. This piece of trim nearly hit the vehicle behind me while driving 45-50mph. I've noticed there are many owners experiencing the same issue. The trim piece is separate from the grille but gm will only sell the full grille replacement. The upper piece needs to be redesigned for safety purposes and replaced on all similar models.

Trim piece of chromed plastic on the front of the hood broke off and flew over the truck while traveling at 65mph. Fortunately no vehicles were close behind, but it could have damaged a following vehicle and/or caused them to swerve to avoid. This part is obviously a defective assembly. Photo available.

Top grill piece attached to hood blew off in the wind.

I was driving on the highway at approximately 65mph and the upper top moulding suddenly broke off, flew across my truck hitting my windshield, before landing in traffic. I had not had any previous damage to my truck prior to this incident. I am concerned this is a widespread issue that is creating an undue burden on the owners and potentially create unsafe conditions to nearby vehicles/pedestrians. I took my truck to the dealership as I have a warranty, but they refused to cover the cost of replacement.

I was driving down the highway at approximately 60 mph, and the upper front trim from above the grill flew off, struck, and cracked my windshield. Based on my research, this is a very common problem and a serious safety concern for drivers of 2022-2024 GMC sierras. It is also a safety issue to the general public for anyone traveling or walking near this vehicle when this condition occurs. There was also an article published on gmauthority website about this common issue as well as multiple reddit posts and gm forums.

As I was driving down the highway, the top piece of the grill flew off, went airborne, and almost struck the vehicle behind me. When I got home, I looked to see what caused this to happen. The piece was secured by flimsy plastic clips which had broken off. This is a complete manufacturing defect which is on GMC Sierra 1500s years 2022 to present and needs to be recalled. It's happening to a huge number of people based on the reports on facebook groups.

As I was driving down the road the front upper lip of my grill blew off and hit my windshield and then flew into car behind me. Looked online and this is a very common theme with GMC built in 2021 & 2022.

Front upper grill trim piece flew off truck causing a safety hazard for myself and others behind me. Flimsy tabs had broken and wind ripped the trim off.

Upper bumper flew off driving on the highway.

On October 10 about 9am driving out of town on vacation for not reason at all my 2022 Sierra 1500 front upper lip of my grille broke off on freeway and we could not find it.

The upper trim piece of the grille broke off while driving down the road the other day. The piece flew up onto the window creating a distraction to myself and the vehicles behind me. The problem can not be reproduced by the dealership as its broken in pieces on the side of the road. Based on internet research this is a common occurrence. The vehicle has not been inspected by others there where no warning signs, messages or symptoms of the problem prior to the failure of the grille.

Driving down the road at 60 mph, the front upper grill piece just came off, flew up into the windshield and then over the cab of the truck and landed in the street. This is a known defect on these trucks and has happened in 100's of cases. When it happens it makes you react as if you had hit something with the truck, if there had been anyone behind me it could have also caused damage or made them react badly to something flying thru the air. When it happened to me I was prepared for it since I had read online of it happening to so many people. The cause is that its build with really flimsy, very thin tabs that just cant hold up to the wind speed and use needed for being mounted in the front of the vehicle.

While driving in the highway at 60 mph, the top of the front grille flew off, hit the hood, and impacted the windshield before flying off to the passenger side of the vehicle. It impacted multiple locations on the passenger side of the vehicle as it flew off. Nothing hit the grille at the time it flew off. We were driving on a busy highway. Thankfully, the cars behind us were at a safe distance. If there were a motorcycle or another vehicle, it could have seriously injured someone or caused them to swerve their vehicle. Researching this online, multiple owners of the same vehicle have experienced the same issue. Many experiencing it when traveling at highway speeds. It seems like the thin plastic tabs that attach the top grille piece to the front of the vehicle are not strong enough to hold it. No damage had been done to the grille prior to the incident. I always use a touchless car wash, so it wasn’t loosened by that. I haven't contacted insurance or filed a police report. I'm hopeful the damage will be covered under the manufacturer warrant.

I was driving down the interstate when the top trim panel of my grille flew off my truck. The piece flew into the traffic behind me, and fortunately, no one was injured. If there was a motorcycle behind me, the rider could have been severely injured or killed. The piece that flew off is located just above the grille and below the front edge of the hood. Multiple people have reported the same issue with their trucks. This morning, the parts department at my dealership confirmed that I was not the only customer to present this problem. There is nothing to warn of the problem before this piece flies into traffic.

A large part of the grill on the front of my truck but broke off on it's own while I was driving. The part is called the upper grill molding part number 20863. It's about the size of a ski (5. 5 ft long and 6 inches wide). It flew off and almost hit the car traveling behind me. They had to swerve off the road to avoid hitting it and almost got into an accident. After inspecting the part and how it is supposed to attach to the grill, it is apparent that is was very cheapy installed with flimsy plastic mounts and minimal glue. My truck only had 19,000 miles on it when this happened. I took it to the GMC dealer and they said the entire grill would have to be replaced because they don't sell that part separately. I researched this issue online and found thousands of other cases with the same scenario happening. This manufacturer's defect should be recalled as it poses a severe safety risk to pedestrians and other vehicles.

I was driving on the highway around 70-75 mph and the upper moulding on the grille flew off and hit the windshield.

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.

Driving down the road and a large section of my grill came flying off the truck, hitting my windshield and the car being me. I pulled over as soon as it happened and the car that was hit kept going and did not stop. After a search on the internet it has brought up serval cases of this happening to other owners. This would of killed a motorcycle driver if he was behind me. We need action. [xxx] 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.

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.

Upper molding of grille flew off while driving. Seems to be a common problem amongst 2022 models of at4.

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.

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.

Complete engine failure. Replaced engine in February of 2024. Multiple transmission issues. Grill completely peeling off.

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.

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