Bad paint used by manufacturers that causes frames to rust out.

While driving 65mph in my 2024 GMC sierra denali ultimate on interstate 270 in hilliard, ohio my chrome grill deflector just flew off and hit my windshield. It then went over my truck and almost caused a major accident with the cars and semi-trucks behind me. I was lucky to maintain control of my own vehicle! it appears to me that the mounting fractured and it looks like manufacturing defect. Looks like the same issues recalled in 2022 year models. How many have to die before gm fixes this issue? they now want $1,500 for a new grill on my 2024 truck.

I was driving down the road and my top grille molding flew off.

The motor stoped working 6. 2. Left me stranded in the middle of the road. No warning, the engine just gave up and stopped working. As well as the grill flying away and breaking my windshield, this happened last year in February while driving 75 mph.

The top part of the front grille fell off while driving.

The front upper grille molding/deflector located above the front grille and directly below the hood on my 2022 GMC Sierra 1500 has become loose and is separating from the vehicle. The left side attachment points appear to have failed, allowing the plastic component to visibly move and lift while driving at highway speeds. The condition worsens with airflow, and the part vibrates and flexes significantly while traveling on the freeway. This creates a safety concern because the component appears at risk of detaching completely from the vehicle and becoming roadway debris, potentially striking other vehicles or causing drivers to take evasive action. No warning lights or dashboard messages were present prior to discovering the issue. The problem was first noticed after observing movement of the grille trim while driving at normal highway speeds. The vehicle has not been involved in any collision or modification that would cause this condition. A GMC dealer inspected the concern and confirmed the vehicle is not currently included in an active recall despite an existing GMC recall addressing grille deflector detachment on similar 2022 Sierra 1500 vehicles. The defective component is currently still installed on the vehicle and available for inspection upon request. Due to the risk of detachment while driving, vehicle operation at highway speeds now presents a potential hazard to surrounding traffic.

Front grill deflector detached from vehicle when traveling on highway. This is a recall repair for the same issue. There were no warning lamps.

While driving on interstate 10 at 70 mph the upper section of the front grille broke off. After the part broke off it contacted my windshield before continuing to fly off behind him. Not only putting me in danger but also anyone traveling behind me. From online research the is a recall for this truck except the 2022 models after the same thing happening.

Upper grille deflector flew off vehicle while operating. No previous damage, just flew off. There is the same issue with my make and model that GMC issued a recall for but it is not appearing for my VIN.

While driving on the interstate the top part of the grill flew off into following traffic.

Front grill cap blew off while driving.

I was driving on the highway (using cruise control) when the front bumper grill started vibrating (so I tried to slow down) but it kept flapping and flew off before I was able to pull over. I then pulled over on the shoulder and had to walk back to retrieve it. My safety was put at risk because it could have hit my windshield and caused me to have an accident, or, it could have hit someone or another vehicle. I have it and it is available for inspection. It has not been inspected by anyone yet. There were no warning signals prior to the failure.

I was driving on the interstate when the hood deflector blew off suddenly and unexpectedly damaging my hood and hitting the windshield. This vehicle was recalled for this part defect last year and the fix was applied by the dealer. It appears that some sort of adhesive was applied to the retainers but they still ultimately failed. This was a very dangerous situation that could have ultimately caused an accident. I am reporting this so that the approved repair can be reviewed. This part should have been replaced, not simply placing adhesive on the defective part. The past safety recall # was n242490120.

I was driving down the road the front piece of the grill flew off the truck and hit my windshield, then flew into oncoming traffic.

Upper part to the front grille detached from bumper while driving, causing loud impact on windshield (cracking it) and scratching hood.

While driving down the highway the top part of the front of the grill flew off bounced over top of my vehicle and landed on the ground in the highway where the car behind me then ran it over and it blew into the median. I notified my local GMC dealer who said there is no active recall. Filed a complaint with GMC as this is a known issue and has already been recalled on the 2022 model. They reviewed and denied my claim at this time. It is a known manufacturer issue and creates a highway hazard if they continue to blow off and possibly hit or injure athers.

The other night, I was backing into a parking spot at the market. As I slowed I noticed the brake pedal was getting harder to depress and it felt as though I was going to back into the car behind me. It took more effort to stop the truck.

The grille deflector suddenly detached from the truck and flew off into traffic. It narrowly missed the vehicle behind me and could have caused a serious accident or injury. There was no prior warning or impact that would explain the failure.

I was driving down the highway at 65-70mph and the top part of the grill flew off, causing scratches to the wind shield. There’s has been a recall on this for 2022 GMC 1500 sierra’s but I am driving a 2024 and the issue is still the same.

The frame of the back window is cracking allowing water to come in through the back glass. This is causing the headliner and other components such as air bags and other electrical components to get wet and damaged. This could cause risk of fire or failure of safety components within the vehicle such as air bags, cameras and other sensors. With water intrusion comes the high risk for mold to develop and cause serious health risks. GMC is aware of this issue and will not agree to repair it. A GMC dealer has inspected the glass and said it was a faulty seal but since it's not in the 3 year warranty window, it's not covered. Independent auto glass companies state they have seen this issue many times and the glass seal is faulty. GMC should do the right thing and fix this issue. This devalues the vehicle and the GMC brand and poses serious risks to driver. I have created a case with GMC and submitted photos, videos and dealership estimates for proof.

Grille deflector was torn off the vehicle while driving at highway speeds.

Upper grill molding trim/bezel flew off truck. Part was recovered and clips look to have broken off. Plastic clips look to be insufficient and will break over time. Active recall for 2022 model vehicles only , needs to be expanded to 2023 or possibly further out.

I was driving down the interstate going 64mph and my grill deflector flew off. Then a piece of the bracket flew up and landed on the hood about 7-10 miles afterwards.

Took truck in to have brake light checked to prepare for a trip. Got a call the next day from auto service center that the frame off the truck is completely rusted and that it was unable to be lifted up for service. They stated that the vehicle was unsafe to drive and that any hard bump, speed bump or over correction could cause the frame to fall out.

Molding between top of grill and hood came off while traveling on highway and struck windshield and broke it.

The top of front grille broke off at 70 mph, struck the windshield then the fixed antenna on top of the truck then into traffic behind me all doing 70+ mph across a one mile long 2 lane bridge with no place to avoid the debris. The failed part endangered myself, my family and anyone traveling behind us. No one has seen the remnants of the event/ issue but the part was approximately 2ft long and 8 inches wide. The truck has a top piece that sits between the hood and the top of the grille. The part is gone but one can see the broken clips and flimsy plastic. The previous year model of the truck had a recall opened earlier this year for the same problem but not my truck. Multiple forums online report the same event as mine occurring on multiple model years.

Just purchased 2022 GMC sierra elevation with 25,000 miles on it. The undercarriage is completely rusted and makes a terrible ticking noise. I have read that there is recalls and issues with this on a lot of of the trucks.

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.
