ENGINE
The coolant control valve failed. This is a known failure point of poor design and on every other truck from 2019-2023 with the duramx LM2/LZ0 engine, they are covered by a special service warranty to 150,000 miles. GM knows this items fails and puts consumers lives at risk when the failure throws the truck into limp mode on the freeway. They refuse to do a recall to avoid doing the right thing. This is deceptive and wrong.

On 2/23/26 my GMC sierra 1500 AT4 3.0L Inline-6 Turbo-Diesel, it auto stopped (which I will never keep on again) on an incline and would not start back up or shift gears and rolled a few feet. I had to turn it off and restart it, then the engine light came on and a notification about conditions not favorable for shifting? My app said service was needed for engine/transmission issue. I took it to the dealership and it now has to have the transmission control valve body assembly replaced. I did not receive a recall notice for my truck but, it seems to be the same issue that the recall was for on GM vehicles of the same time period. Of course the dealership said they have no loaner vehicles and I'm supposed to be without my truck for approx. a week and a half at this point. I am disappointed with GMC and the quality that I am paying $70k for. I had a 07' Silverado 2500 I purchased new and drove it for almost 15yrs. w/ no issues. Hopefully this is a good fix and it'll last but, from what I've seen, GM is not the quality it used to be. This is on top of being in the shop for a coolant control valve issue that wasn't recalled either but, a known issue on the pickups so beware. I did call GMC and they will reimburse up to $44 a day on a rental (has to be a GM vehicle btw) during this fiasco of course afterwards and with a bunch of paperwork but, I have to have a vehicle, in TX nothing is close by. Good luck everyone!

STRUCTURE:BODY
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.

AIR BAGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
Following engine replacement per NHTSA for 6.2l GMC engine. I am submitting a safety complaint regarding my 2022 GMC Sierra 1500 Denali (refresh body style). The vehicle has experienced repeated failures of driver-assist features and safety system warnings, including: Dash messages: “Lane Keeping Assist System Unavailable” and “Service Safety Restraint System.” When the fault occurs, driver-assist features including Adaptive Cruise Control become inoperative. The issue has recurred multiple times, including after repairs. After one event, the truck sat parked approximately 10 days and the battery discharged to failure and required replacement. A dealership visit documented DTC U3000 (“Internal Electronic Failure”) in the front view camera module. The dealer replaced/programmed/calibrated the front camera on 02/09/2026 at approximately 58,405 miles (invoice/RO #285795). The symptoms have recurred despite prior resets and this repair. I am concerned about loss of driver-assist functions while driving and the presence of a safety restraint system warning. Please investigate whether there is a defect related to the front camera/driver-assist systems and/or electrical module behavior that can cause repeat faults and battery drain on this model.

UNKNOWN OR OTHER
coolant control valve failed, truck cannot be driven due to overheating, Dealer has said due the national backorder, it could be 2 months before they receive the replacement part. There is a significant national backorder on the engine coolant flow control valve for 2020–2025 GMC Sierra and Chevrolet Silverado trucks equipped with the 3.0L Duramax (LM2/LZ0) diesel engine. Many owners are reporting wait times of several weeks to months, with some vehicles sitting in repair shops for over 70 days.

ENGINE
L87 Catastrophic Engine Failure on second engine after 6300 miles. This is the second issue with the 6.2L engine in my Sierra 1500. The first engine passed the L87 Engine Loss of Propulsion field action and then suffered Catastrophic Engine Failure a month later. The replacement engine procedure took over 3 weeks to perform and no rental or loaner vehicle was provided by GM or the servicing dealership. The vehicle is currently in the service department at another dealership awaiting the 2nd engine replacement, but it has been over 2 weeks since the engine failure. This servicing dealer has provided a vehicle to use. This has been a very frustrating ordeal and I feel that resell and value of this vehicle has been compromised and GM has done nothing to offset this with me.

ENGINE, FUEL/PROPULSION SYSTEM
The vehicle is subject to Safety Recall N252494001 (NHTSA Campaign 25V-274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • Component/System Failed: The 6.2L V8 (L87) engine crankshaft and connecting rod assembly. The engine is available for inspection upon request. • Safety Risk: The defect can cause catastrophic engine damage and sudden loss of propulsion while driving, significantly increasing the risk of a crash. • Dealer/Manufacturer Confirmation: The problem was confirmed via the issuance of Safety Recall N252494001. A dealership inspection was performed previously as part of the recall. • Warning Signs/Symptoms: Common symptoms include engine knocking, check engine lights, and hesitation before sudden failure. The Issue with the Remedy: Federal law (49 U.S.C. § 30120) requires manufacturers to remedy safety defects "without charge". As a permanent safety remedy for this defect, GM has mandated a switch from 0W-20 to 0W-40 (dexosR) oil for the life of the engine to prevent bearing failure. However, the dealership and manufacturer are refusing to provide this mandated safety spec change without an ongoing $85 surcharge per oil change. While they performed the initial "inspection" oil change for free, they are now using the recall-mandated spec change to create a financial burden on the consumer. Because 0W-40 is now the mandatory factory requirement to prevent the safety defect, charging a premium for it constitutes a failure to provide the recall remedy "without charge." General Motors refuses to offset this cost, effectively penalizing the owner for a manufacturer safety defect. The dealership is also failing to honor my Platinum Wrap warranty and GM Prepaid service contract to perform the continued oil changes without additional charges.

ENGINE, VEHICLE SPEED CONTROL
While driving I get a reduced acceleration warning on my dash cluster, drastically reducing horse power. My check engine light came on. This has happened before. I checked the code and it was a P1098 code. After researching I found out it was the Engine coolant control valve. My fan is constantly running. This issue is ongoing. This seems to be a common occurrence with my vehicle year.

ENGINE
My GM Dealership completed the GM 6.2 Engine Inspection and recommended Oil Replacement as part of the 6.2 Engine Recall. Roughly 5,000 miles after this service, the engine failed. I attempted to accelerate from 45-65 miles per hour while getting on the highway, and the engine seized up. I was able to coast/steer the vehicle to the side of the road. The vehicle's starter could not crank the engine. I had the vehicle towed to the shop where the dealership confirmed the engine had seized. The dealership and GM replaced the engine under a warranty repair. I am making you aware of this situation, as the manufacturers suggested solution to the engine issue (The Change in Oil Type, Filter and Cap) did not prevent the engine from failing.

engine recall 6.2 L-87 , after Pico scoop Test, which my truck passed, its using 2 plus quarts of oil per 1000 miles, the dealer has it and is saying they can find nothing wrong per the gm tech that is telling them to check this and that. Ok, oil is going somewhere, I want the motor replaced , they want to continue the oil consumption test, my thing is wasting my time to continue driving and bring back to it back for a low oil reading, Its not gonna fix its self by driving it. I understand gm wants to figure out why, but it should not be at customers time , replace the motor all ready, something is wrong. the first 1000 miles after a oil change and they put die in the oil to check for leaks. When They check the oil level friday 02/06/26 the oil did not read on the dip stick.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The front forward-facing camera module has failed, causing cruise control and driver-assistance features to become inoperative. Dealer diagnosis indicates the front camera must be replaced and recalibrated in order to restore cruise control and safety systems. This failure disables cruise control and driver-assist features that were standard equipment on the vehicle at purchase, resulting in a sudden loss of functionality while driving. The dealer has provided a repair estimate of approximately $1,150, including parts, labor, and required calibration, at owner expense. Based on similar reports from other owners, this appears to be a recurring issue affecting this model year.
