Body Problems of GMC Sierra 1500 - part 1

The upper part of the grill detached on my 2023 GMC Sierra 1500 while going 65mph on the higway. The part is about 4 inches wide by 6 ft long. People behind me in traffic were swerving and dodging to avoid hitting it. Gm knows about this problem (see safety recall #n242490120), but the scope of the affected vehicles is incorrect, so my truck is not included. There were no signs that the part was going to fail before hand.

--radio power button inoperative --radio channel change buttons, to left of steering wheel inoperative (everyday) --radio volume inoperative -just stops working (sometimes) --radio “home” button, left of radio power button inoperative --driver door mirror wobbles when above 50 mph (very distracting when driving) --driver door hard to close and out of alignment --dealership is selling the vehicles knowing some of the issues are present, but not advising the buyer. My safety is/was at risk due to having to move my hands off the steering wheel to touch the radio display to make any changes while driving. A certified gm service dept confirmed all my issues and could not repair. They quoted a pit 6408. However, this particular pit does not address my issues/concerns.

Part of the grille of my 2023 GMC sierra at4x flew off driving 75 miles per hour on the highway, I believe it has to do with the fasteners of the upper grille bezel.

After completion of a recall fix by the dealer for the grill while driving the front grill deflector detached striking the front hood and top of the cab before flying behind my vehicle barely missing a following vehicle and settling alongside the road. I pulled over, inspected the front of my vehicle to assure it was safely drivable. Once I removed loose pieces I returned and retrieved the top grill from the roadside then drove directly to the dealer who completed the recall fix. They have ordered a full grill for replacement. The recall fix/repair failed within day of completion.

Recall number n242490120 was performed in April 2025 rivard Buick GMC, tampa, florida, phone # 813-620-6500 the grille was inspected and repaired with adhesive to reinforce the plastic tabs to the grille so it would not detach and cause a safety issue when driving. This recall was performed before we purchased the vehicle and we are located in oklahoma city, ok. The vehicle has been listed for sale at our car dealership in oklahoma city and had to have multiple warranty repairs at GMC/chevy over the summer. We sold the vehicle on 8/9/2025 to a customer: ruben ivich and he was driving the vehicle and the grille detached and fell off the vehicle while driving. The grille hit his hood and windshield and caused damage. He could have had an accident when the grille detached from the front of the vehicle. We dropped the vehicle off at bob howard GMC on 8/26/25 and they said since the recall has been performed that it is not covered and nothing they can do about fixing it under recall or warranty. We reached out to GMC customer service 1800 # and they told us the same thing, and we would have to repair it out of pocket. I find this extremely unprofessional and avoiding taking care of the issue that should have been taken care of the first time. The part is faulty and part of the recall to be repaired or replaced properly so this hazardous part does not cause a problem while driving and that is exactly what happened even after having the recall taken care of at GMC. We at la raza motors inc. Have inspected the vehicle/grille and upon discovering the previous recall/repair that was performed at rivard Buick GMC in tampa, florida, the grille was not properly repaired and not up to standard. This part should have been replaced instead of repaired. Ruben retrieved the broken/detached grille after it detached to see what had happened and we have pictures. No police report was made at the time of the incident. No lights or warnings were on at the time of the incident.

The front upper grille deflector/hood bulge flew off randomly while driving. No signs of it previously detaching or anything. Just came off.

GMC Sierra 1500 front upper top grille molding trim randomly flew off at highway speed. Hit the windshield and the vehicle behind me. No warning.

March 28, 2025: a recall (NHTSA recall no. : 25v-060) service for the front upper grille deflector was performed. August 7, 2025: the front upper grille deflector flew off my truck while I was driving on the interstate, despite the recent recall service. The failure of a recall repair is particularly alarming and a serious safety hazard.

While driving down the highway at moderate speed (60mph), the deflector, top of the grill broke off the truck, hit the windshield and the top of the truck (causing paint damage) and flew into traffic behind us. The incident put my family's safety and other drivers safety, at risk. I took the truck to a dealership immediately afterwards and they indicated the 2023 version is not under warranty, although a recall exists for previous years for this exact issue. There were no warning lights or messages received prior to the incident.

2024 GMC Sierra 1500. While driving approximately 75 mph, the front chrome grille deflector came loose from the passenger side of the vehicle and started flapping. Before I could safely pull over it became detached and flew over the hood of the vehicle striking the front windshield before nearly hitting another moving vehicle behind me. This caused damage to the hood, the other driver did not stop. While the 2024 model vehicle is not listed in NHTSA campaign number: 25v060000 (structure) recalled on the 2022 model, gm lists the same part number for the 2022-2024 models, therefore the recall should include these years as well. The failure mileage was 27,500.

Multiple times today my tailgate dropped randomly without my knowledge. With the tailgate randomly dropping, and no warning lamps, messages, or other symptoms, it puts others at risk due to the potential for the contents of the truck bed to fall out into traffic causing damage or bodily injury to others on the road. During my research on what could cause this to occur, I was made aware of a recall of this same make, model, and year vehicle. The description of the reason for the recall was exactly what I experienced with my vehicle. I immediately attempted to confirm that my vehicle was listed on the recall by entering by VIN online. I discovered that there was not an active recall on my specific vehicle, so I contacted the nearest GMC dealership. After speaking with the service tech, he confirmed that my symptoms was exactly what the dealership had addressed with other vehicles that were on the recall list. He confirmed that my VIN was not included, yet the recall did have the same make, model, and year. I will be making an appointment at my dealership to repair this at my expense since it is not covered on the recall.

2011 GMC sierra frame failed pennsylvania state inspection due to driver side frame rust/hole. The section of the frame must be replaced due to rust(improper coating. . . The truck has only 69700 miles on the odometer.

Tailgate opened several times without being prompted. Once while driving, two times while in park.

The chrome grille deflector detached yesterday while on the interstate and landed in traffic behind me. Gm recall number n242490120 does not cover my vehicle, but the same thing is happening to newer models. Gm says they won't cover my vehicle under the recall. Can this recall be extended to newer models?.

The upper portion of the front grille is loose and about to fall off. I know GMC has a recall on some trucks for this issue, however mine is not listed on this recall although I have the exact issue as the recalled trucks. It’s just a matter of time before this comes off driving 70 mph on the highway and could strike a vehicle behind me causing an accident. I noticed this being loose back in June 2025.

My multipro tailgate on my 2020 GMC Sierra 1500 unlatched while a trailer was attached and backing up said trailer. The trailer jack post proceeded to buckle the upper part of the tailgate assembly causing extensive damage resulting in over a three thousand dollar repair bill. If the tailgate had released while a child was in close proximity, serious injury may occur. The tailgate has inadvertently released twice in the five plus years I have owned it, the first time as I was traveling down a highway at over 60 mph. This could have endangered a vehicle to my rear if cargo had been released on to the road. I have reached out to a local dealership for repairs and assessment, no real way of troubleshooting something that has happened twice in five plus years. The scan did not show any codes. The info center does notify you if it is released but not before it takes place and after the fact may be too late in some circumstances as it was during the second occurrence. There has been a recall on 2500 and 3500 models with the exact same tailgate but not the 1500 models. 820k vehicles affected but not on the 1500's.

While driving on I-45 from houston to san antonio the front grille spontaneously flew off from my hood and hit my windshield. Grille damaged the hood but no known damage to shield. This was very frightening while on a highway because it almost caused me to crash as it triggered my ptsd from the blast and led me to swerve. Fortunately I regained vehicle control and avoided other damage to others.

The top front grill became detached at highway speeds.

Tailgate switch tailgate opened on its own with trailer attached while driving damaging the top of my tailgate. No notification inside cab. No console / fob / tailgate buttons were pushed. Discovered tailgate was down after I arrived home and had done a wide u-turn in my back yard. So far dealership has done very little diagnostic wise. Two trips to dealership so far with little to no results. Now I’m scared to use my trailer or utilize the bed of the truck to haul anything due to tailgate might open on its own at 75 mph on a major interstate/ 2 lane road hurting or killing the people in the vehicles behind me. Totally unacceptable from GMC / dealer for a 70k truck.

While driving down the interstate the upper grill piece broke off. The mounting tabs holding the piece broke.

During an oil change in may I was informed that my frame was extremely rotted and was in jeopardy of cracking in half . The further I dig into this, I'm finding that gm is aware of this issue. The vehicle is available for inspection.

Hello, I wish to report this injury / incident with the failure of the power running boards on my 2022 GMC Sierra 1500 denali limited. There are no warning lamps on the vehicle. The truck is regularly serviced and inspected. The truck recently had a multi-point inspection at the dealer. The power running boards started to come out after I opened my door, as I stepped down, the steps retracted and went back in causing me to fall hard on the ground and smash my knees. Driver and passenger sides are now acting up, even with the truck parked and locked, passenger side wants to go in and out on its own and sometimes extends to the tire. As I researched this problem, I found out that others have had similar issues with the same vehicles that have these power running boards. I removed the fuse now to prevent further injuries.

At approximate 36700 miles. Upper top molding piece next to the grill, flew off while driving down the highway at 75mph hit my windshield and cracked it. Lucky no one was flowing me. This is the second one that's has broken. The first time was driving in south dakoda the day after I purchased the truck and one side broke so I was able to stop at a truck stop and duck tape it until I was able to take it to the dealer. This seams to be a flaw, because read this has happen to multiple truck of the same model.

Top section of front grill (directly below the hood) broke and came up while driving down the highway with no prior indication or damage.

The electronic tailgate randomly opens on it's own/fails and opens when it has not been pushed to open. The vehicle is available for inspection. The tailgate opens randomly and can be unknown that it is open. No warning of it at all. It has happened multiple times, the most recent being today 4/7/2025. I know that a recall has happened with other models for this exact same issue.

Tailgate comes unlatched and tailgate came down multiple times in motion and parked. Safety concerns loosing cargo and causing accidents. My vehicle is not included in the recall and dealer cannot help only repair for 146. 80. I feel that my vehicle should be included to the already existing recall and reimbursement for repair.

Paint is chipping on the body of truck. Door panels and more.

We have a 2014 GMC sierra 4. 3 v6 6 speed automatic. . With only 100k miles and the frame is rusted and cracked rear shocks mounts are rusted and broke and the leaf spring mounts are rusted and they broke. . This should be a recall issue. .

Upper grille came off and fractured windshield while going down the highway it is a non serviceable part by gm which I believe is strategic seeing that they’ve had issues with earlier models of the the truck you have to buy an entire replacement grille for one issue that shouldn’t be happening was never able to locate part, I assume plastic grille clips dry rotted noticed the part lifted a bit before the entire part failed thought someone was trying to break into my truck . The wind while going down the highway caused them to fail, I’ve seen multiple GMC sierras with the same grille issue, I uploaded before and after pictures of how the truck looked before and after pictures .

2025 GMC Sierra 1500 shifted from park to drive uncommanded, accelerated uphill, and crashed while idling, keyfob outside of vehicle, March 2025. Esis couldn't replicate and falsely claimed I didn't put it in drive, despite photos and no one inside.

The grill piece that is recalled flew off while I was driving on the highway on March 14th. I called the dealership that day to get my truck in but could not be seen until April 21st. After having the vehicle at the dealership they said the part to replace is backorder with no eta of when it will be available.

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.
