Driving at highway speed the upper part of the front grill assembly detached at the hood, hitting the windshield on the drivers side causing the windshield to shatter in front of the driver. The piece flew back and hit the car behind me. This would have been an accident with a less experienced driver

The front chrome grill on my Sierra 1500 SLT has begun to detach, and there is currently a recall for this specific component on my vehicle. I took my truck to GMC Covert Bee Cave to get this recall and 1 other recall fixed, but GM does not have a remedy for grill. Not only does this pose a safety risk to myself, but I use my truck as a source of income by renting it out on Turo, and Turo has unlisted my truck from the app indefinitely or until this remedy is resolved. The paperwork I received from the dealership confirms GM has no remedy for the recall, and they sent me on my way without even offering a replacement vehicle. My truck is available for inspecting if you would like to see it. My safety and others safety is at risk if this recall does not receive a remedy or if GM does not give me a replacement vehicle in the meantime. No warning lights or any other systems can notify me if the grill is going to detach all the way, and I will not be able to have this source of income from Turo without the ability to have my truck relisted.

- Copperas Cove, TX, USA

Driving at highway speeds 60 mph. The upper grille (as GMC calls it) came off of the truck, hit my windshield and the car behind me also hit it. This is a known GM problem and they are not issuing a recall on this. We are lucky the car behind me didn't suffer any damage nor swerve to miss the flying piece of my vehicle. This is a huge safety concern that needs to be addressed. A quick google search will reveal many other people having this same issue. Some stating damage to their vehicle as a result.

- East Gull Lake, MN, USA

I was driving home from work on the highway, when the top part of the front grill broke off and flew up hitting the windshield. It caused me to abruptly swerve into the other lane of the highway. Luckily there was nobody in the other lane. The part could of also hit another car that was behind me. Going on line, I see this is quite common issue for 2022 GMC trucks and it occurs on the same conditions, driving down the highway. I suggest a recall to get this fixed.

I was on the interstate going 60-70 mph and I noticed that my front upper trim of the grille was flapping and then just flew off my grille

- Lowell, IN, USA

While driving on the interstate at 75 mph, the top trim from my grill flew off unprovoked hitting my windshield and roof of the truck. Luckily there wasn't anyone behind us but the noise definitely spooked myself and the passenger not knowing what just hit the windshield. I took it into the dealer from who I purchased the truck and told the entire grill must be replaced for a whopping $1571.26 not covered under warranty. The truck only has 24000 miles on it and cost near $80K. Thanks GMC!! Scorned customer.

- Rapid City, SD, USA

Entering a freeway and getting up to speed, the moulding between my grille and hood flew off. I was not able to recover it, therefore it has not been inspected by anyone. Luckily, this happened at night when there were very few drivers on the road, but had it happened during a busy time, it is likely that piece would have hit another vehicle(s). It has been reported as a problem on many forums. This happened without warning and there were no warnings after it occurred.

- Richland, WA, USA

Driving on the highway, the upper grill molding on the leading edge of the hood broke off and came up and hit the windshield and top of the cab. Upon further research online, this seems to be a pretty common occurrence on sierras with the at4 trim package. I was told by the dealership that extended warranty does not cover this and I would have to order an entire new grille, over $1000

- Port Clinton, OH, USA

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

- Las Vegas , NV, USA

As I was traveling down the interstate at about 70 mph the front upper grille moulding flew off and almost hit the vehicle behind me. The clips that held this on the vehicle are very weak and this is happening to many of the same vehicles. Had I hit a car behind me there could have been significant damage, and luckily there was not a motorcyclist behind me. I did not hear any rattling or have any damage to the vehicle, this is simply a manufacturer's issue.

- Knoxville, TN, USA

While driving approximately 70mph down the freeway the upper grille assembly snapped off and went airborne, it struck the passenger side of my windshield putting 2 large scratches on my windshield. It then hit the roof of the vehicle and continued over my vehicle. Upon inspection the guard is held on by extremely thin clips and all clips sheared in almost identical spots. This creates a huge safety hazard for motorists behind the Vehicle that could be struck by the flying piece.

- Colorado Springs, CO, USA

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.

Upper molding of grille flew off while driving. Seems to be a common problem amongst 2022 Models of AT4

- Aubrey, TX, USA

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!

- Fargo, ND, USA

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.

- Spearville, KS, USA

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.
