My 2023 GMC Sierra AT4 with the 6.2L L87 engine is showing signs of premature engine issues despite passing the recall inspection. I hear persistent lifter chatter, which is known to be a precursor to catastrophic failure in these engines. I no longer feel safe driving this vehicle due to the known defect with the crankshaft, rods, and valvetrain. GM issued a recall, but it appears to be incomplete and does not address the underlying issue in many vehicles, including mine. I am worried about sudden engine failure and safety while driving.

After 1-year to date of the first time the engine seized up in 2024 and was replaced with another motor. Then around father's day weekend I went to accelerate on highway and it studder and service symbols for traction control and ESC service popped up. It shook and vibrated while running. The same dealership shop that replaced it last year stated that rods and such have failed. After not resetting the mileage on the dash board for the miles on the truck or extending the warranty on the AT4 2023 model I was skeptical as it ran rough to begin with. I was told that everything is as should be when talking to them in Jan/Feb 2025. Now we're here at the shop AGAIN. the Mechanic at the dealership the first time stated that he mentioned to the manufacturer that the issues he is seeing is tied to the motor and oil transferring and he is not surprised there are the issues but the manufacturer shrugged it off. So, after having the vehicle in my possession for 2 years, I'm having the motor replaced twice in one calendar year and without a vehicle combined and counting 2.5+ months. GMC knew about the issues and decided not to address them. I loved the truck but there were too many issues and it was my first GMC and will be my LAST. I WAS a big Chevy guy most of my life.. Now I'm considering a RAM..

The engine failed while pulling my camper over a mountain pass. This resulted in me being stranded along side the highway with the vehicle impeding traffic. The area the vehicle broke down had no cell phone service to call for help. This engine was a replacement engine and failed with only 20,000 miles. This vehicle is effected by the recent recall the GM issued on all 6.2L engines. The were not indications the engine was going to fail.

Driving on the highway under normal driving condition, my check engine light came on and said service transmission. This then put the truck into "limp mode" and I was stuck going 60mph in a 75mph zone. Dealership scanned and found that the coolant sensor control flow valve is faulty. This part is in such demand for these vehicles that it is unknown when the part will be in.

Diagnostic: Video Processing Module includes replacement and reprogramming and calibrations Diagnostics when referred to in an automotive sense is the various testing done on the automobile to ensure safety and proper engine functioning. These tests are done with different sensors, computers and machines to establish a “cause and effect” relationship between what is working and what is not working with the automobile. The forms of diagnostics can range from brakes, to air conditioning, to suspension and many more. PARKING GUIDELINES ON SCREEN DO NOT WORK AND THERE IS A BLUE HOUR GLASS ON SCREEN. $2,200 estimate to repair.

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?

I was going camping and pulling a small 20 ft trailer with my spouse and 4 young kids in the car when the truck stopped accelerating and would not go over 30 mph on the freeway and the fan started running. There was no warning light on the dash. I was then stranded 2 hour from home with my kids in a gas station parking lot and had to have the truck and trailer hauled home.

Recall N252494000 GM has known about this issue since January (at least) and issued a recall in April. The attached form indicates they are recalling my vehicle but they are unable to repair it. This reduces my value and potentially leads to serious accident and serious injuries. How can GM get away with this? It is a BIG DEAL for a customer to have their vehicle recalled for safety issues like this but not have the manufacturer come out with a fix? What are we as customers to do? Wait until we or someone we love are injured or killed? Please, act quickly! Perhaps a full value buyback offer? Or actually replace the engines that they already know are defective. Changing the oil viscosity as indicated at various online sites DOES NOT FIX THE PROBLEM. Please advise what recourse I should seek. Thank you very much!

The contact owns a 2023 GMC Sierra 1500. The contact stated while driving at an undisclosed speed, the engine seized. No warning light was illuminated. The vehicle was restarted; however, the vehicle failed to start. The vehicle was towed to the dealer where it was diagnosed with fuel pump module failure. The contact was informed that the fuel pump module needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 11,250. The VIN was unavailable.

The original engine in my 2023 GMC Sierra 1500 (6.2L L87) failed in November 2023 at only 2,872 miles. The dealership diagnosed engine knocking and discovered a damaged thrust bearing and crankshaft with metal debris throughout. The engine was replaced under warranty. In April 2025, GM issued Safety Recall N252494001 for the same engine model due to connecting rod and/or crankshaft manufacturing defects. According to GM’s bulletin, engine failure can result in sudden loss of propulsion and increase the risk of a crash. Despite already experiencing this failure and being within the affected model year and engine range, I have been told the recall remedy is not available to me because the campaign applies only to dealer inventory vehicles, and my recall status remains "Recall Incomplete: Remedy Not Yet Available." I requested a safety inspection of the replacement engine, but GM has refused, citing the incomplete status. When I escalated to GMC Customer Care, I was told they could not confirm whether my truck is safe or unsafe to drive. This is after already being stranded once with a family vehicle that cost nearly $80,000. I frequently drive with my family and feel I am being left at risk. GM appears to be prioritizing unsold vehicles while leaving current owners without support or assurance. The current engine has not yet failed, but I have no confidence it is safe, especially as it may include the same defective components described in the recall.

The tailgate automatically opens when I open the driver door. There is a recall on this for GMC Sierras, same model and year but were manufactured in Canada. This is happening to my vehicle but because it is manufactured in USA it is not part of the current recall. PLEASE recall the USA trucks too. Dangerous!

The contact owns a 2023 GMC Sierra 1500. The contact stated that while driving 75 MPH on the interstate, the upper lip of the front grill detached and flew over the windshield into oncoming traffic. The driver was unable to retrieve the part. There were no warning lights illuminated. The contact called the local dealer, who confirmed there was no recall coverage on the VIN for the failure. The dealer informed the contact that the part was on backorder. The vehicle was not diagnosed or repaired. The contact called another local dealer, Ross Downing Chrysler Dodge Jeep Ram (500 Westin Oaks Dr, Hammond, LA 70403) and was referred to the manufacturer for assistance. The manufacturer was contacted and confirmed that the VIN was not under recall and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 50,000.

While driving vehicle I received a message on the dashboard, "Reduced acceleration, drive with caution" and then the check engine light came on. Took the vehicle to local Autozone to get code read and was told "P1028" was the error code. Schedule an appointment with local GMC dealership for diagnosis. After three days dealership told me that the technician has diagnosed my truck with faulty "Engine Coolant Control Valve". I was told the part is backordered with no ETA. Asked for a loaner vehicle while truck is waiting repair and was told there was nothing available. When asked about what I should do transportation, dealership told me I could come pick up the truck and drive it until part arrived but I would need to watch for further engine issues as the engine could overheat. How do you tell a customer to just continue driving a vehicle with a known issue. Additional fear is what if additional harm is caused and because I drove the vehicle with a known issue they won't cover the cost of repair? This all seems fishy and unfair as a consumer.
