After numerous attempts getting GM to finally look at why my vehicle because after the L87 engine swap, which failed after the Pico test and oil, oil filter, and oil cap change my truck has been dangerous to drive. It falls on its face when taking off or driving. It acts as if something is holding the truck back. It takes more throttle to get it moving. Then in traffic while moving it randomly lunges forward very quickly as if I have the gas pedal to the floor. I came very close to rear ending a Deer Park police vehicle. They told me to get my own alternate transportation and they would then look at it. I had to go out and get a rental car. I had no choice. I explained due to my HIGH medical bills following a cancer diagnosis, I could not afford a rental and my appointments. They basically told me come see them when i can make my arrangements. So, i rented a car, took the truck in, four days later i was told that the problem was my ADAS camera. I told them it worked fine before yall had it 3 months waiting on an engine. They told me I would have to pay around 1000 dollars to have my truck repaired. Even though it was clearly something they did. I made arrangements to pay them. I picked up my truck. That evening I was happy. Well, the next morning while going to get coffee the problem returned. I took it back to the dealer. I was again told, go get another rental and leave it here. I have done that. Well, that week went by. I had to borrow money to get the rental for another week. So, i could make it to my cardiologist today. I have to get cardiac clearance before i begin surgery Oct. 1st. Between now and then, i have an appt with pain mgmt., A PET scan, and an Echo/Doppler for cardiac clearance. Surgery begins Oct. 1st. This has been making it very difficult to manage appts. with Gastrointerology, Cardiology, Oncology, Infusion services, Pain mgmt., Therapy with a Psychiatrist, My new Esophogealist (for surgery). And follow-ups and blood tests. This is ongoing.

My 2022 GMC Sierra 1500 was subject to GM safety recall N242490120 / NHTSA 25V060 for an upper grille deflector that could detach from the vehicle. The recall repair was completed by my GM dealership in June 2025. In late August 2026, while driving normally on the highway, the same upper grille deflector detached again in the exact manner described by the recall. There was no collision, impact, or other outside damage that caused the failure. I was able to retain the detached deflector due to my attentiveness however, it was close to detaching and either busting mine or someone else’s windshield. Upon inspection, the adhesive and retainers from the previous recall repair are still clearly visible, and the bonding appears to have separated. I have photographs documenting the failed attachment points and still possess the undamaged detached component for inspection. My GM dealership inspected the vehicle after this failure and determined that the front grille assembly should be replaced. However, because the recall is shown as previously completed, GM has stated that the recall cannot be reopened. GM Customer Assistance offered only $251 toward a $1,673.82 repair, leaving me responsible for $1,422.82 to correct the same safety defect that the recall was intended to remedy. I am filing this complaint because the recall remedy appears to have failed, allowing the recalled component to detach from the vehicle again. A grille component detaching at highway speed could strike another vehicle or create a roadway hazard. I am concerned that other vehicles repaired under this recall may experience the same post-recall failure. I request that NHTSA review the effectiveness and durability of the remedy used for recall N242490120 / 25V060.

The message "Conditions no Longer Exist for Driving," was displayed on the screen. The vehicle was towed to the dealer and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The contact was informed that the nuts were welded to the engine, causing a failure with the engine overheating. The failure also occurred while driving 65 MPH, and the transmission shifted into neutral with the same message displayed on the screen. The vehicle was towed back to the dealer, and it was diagnosed with engine failure. The contact stated that the engine was replaced. The dealer informed the manufacturer of the failure.

On August 22, 2026, while driving my 2022 GMC Sierra westbound on State Route 84 at highway speed, with strong westerly winds of approximately 35 knots, the front passenger-side wheel-opening molding/fender flare completely detached from the vehicle without warning. The detached molding struck the passenger-side exterior mirror and narrowly missed a motorcyclist traveling behind me. This created a serious safety risk because a substantial exterior component became a projectile at highway speed and could have struck the motorcyclist or another vehicle. There were no warning lights, messages, unusual noises, or other symptoms before the failure, and there was no known collision or impact preceding the incident. I did not initially know what had detached. After arriving home and inspecting the vehicle, I discovered the entire passenger-side front wheel-opening molding was missing. The detached component was not recovered. I reported the incident to my GMC dealer, which performs my regular service and warranty work. The vehicle was inspected on August 31, 2026. The dealer declined warranty coverage but, to my knowledge, did not determine why the component detached. Afterward, I inspected the corresponding driver's-side molding and found a substantial visible gap at its leading edge between the molding and vehicle body. Comparison with other GMC Sierra vehicles of the same model showed their moldings appeared to sit substantially more flush. The vehicle and remaining molding are available for inspection, and I have photographs documenting the condition. The cause of the failure is currently UNKNOWN. I have escalated the incident to GMC Customer Assistance under Case #109189284 and requested a product-safety review. I am concerned there may be an installation, attachment, or component-retention issue that could allow these moldings to detach while driving.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure.
