ENGINE
While driving on the highway, my SUV lost speed and went into what I believe was limp mode and the check engine light came on. I was unable to accelerate quickly which was very dangerous on the highway as I was only able to very slowly go about 45 MPH on a 65 MPH highway. After the dealer inspected it, I was told I needed a new engine, oil cooler, and turbo. They said it had metal in the oil. My SUV only had 2138 miles at the time of incident.

ENGINE
Vehicle (engine) shut off while driving on highway. Would not restart. Had vehicle towed from highway to repair shop. No check engine light ever came on. The engine was replaced and old one had to be returned in order to avoid paying a $5,000 core charge. I found out after replacing the engine that GM issued a recall but I read it starts with 2019 models and only reimbursement for original owners. I purchased this vehicle from a GM dealership in CT (Scranton of Vernon) in 2022 with approx 52,000 miles.

ENGINE
I am the owner of a 2024 GMC Yukon Denali/AT4-T1, currently subject to GM Program #N252494000 for the L87 Engine Loss of Propulsion engine defect that can cause sudden engine failure, loss of power, and safety hazards. My vehicle has approximately 18,000 miles and is my primary mode of transportation. GM has informed me that I cannot request an immediate inspection and that they are randomly selecting affected vehicles for inspection without a clear timetable. This means I must continue driving a vehicle with a known safety defect that could fail at any moment — creating an unreasonable risk for myself, my passengers, and others on the road. My dealership has confirmed they cannot perform the inspection until GM activates my VIN in their system. No estimated timeframe has been provided. Given the severity of the defect and the potential for catastrophic failure without warning, I respectfully request that NHTSA investigate GM’s phased approach to inspections and determine whether this practice is consistent with the safety obligations under 49 U.S.C. Chapter 301 and related regulations. I also request guidance on how I can have my vehicle inspected immediately to mitigate risk. Thank you for your attention to this matter.

ENGINE AND ENGINE COOLING
The contact owns a 2015 GMC Yukon Denali. The contact stated that while driving 80 MPH, the vehicle hesitated, and failed to accelerate as intended while depressing the accelerator pedal. In addition, there was an abnormal knocking sound coming from underneath the passenger’s side of the vehicle. The check engine warning light was illuminated. The contact arrived at the residence and used a personal diagnostic reader and retrieved information related to misfires in cylinder #2 and #4. The contact replaced the spark plugs and the ignition coils. The contact test drove the vehicle, and the check engine warning light later illuminated. The contact swapped the ignition coils; however, the failure persisted. The vehicle was taken to the dealer where it was diagnosed that Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) had failed and caused the lifters to fail. The vehicle was not repaired due to the cost. The vehicle remained at the dealer unrepaired. The manufacturer was made aware of the failure but offered no assistance. The failure mileage was approximately 96,000.

ENGINE
1. The engine is malfunctioning, leading to excessive oil consumption and random shutdowns. The vehicle is available for inspection at Alexander Buick GMC, Oxnard, CA, where it has been taken for repairs multiple times. 2. The engine's random shutdowns pose a significant safety risk. The vehicle can stall without warning while in motion, which could lead to accidents, especially in high-traffic situations or at high speeds. This puts the driver, passengers, and other drivers at risk. 3. Yes, the dealership Alexander Buick GMC has confirmed the excessive oil consumption and has observed the engine shutting down. However, they have not been able to determine the root cause of the shutdowns. 4. The vehicle has only been inspected by the dealership Alexander Buick GMC which is an authorized service center for the manufacturer. It has not been inspected by any other parties. 5. There were no warning lamps or messages consistently appearing before the engine shutdowns. Sometimes, the oil pressure warning light would flicker briefly before a shutdown, but not always. The excessive oil consumption was noticed approximately a year ago before the shutdowns began. Not too sure when these shutdowns started occurring.

SERVICE BRAKES, STEERING
1. First incident While driving, the brakes failed and the entire infotainment/tablet system locked up. This presented a severe safety risk to my family and others on the road. The vehicle had to be towed to DEALER where I was told that “no problems were found.” I documented the incident with photos and videos showing the warning messages and system status. 2. Second incident Approximately one week ago, after shutting off the vehicle, a “steering wheel lock” warning appeared and the truck became completely disabled. Even with jumper cables, it would not start. The vehicle had to be flatbed towed to DEALER. I again documented the incident with photos and videos showing the warnings.

ENGINE
GM may be installing recalled engines into other vehicles through warranty replacements, avoiding recall accountability. I purchased a 2021 GMC Yukon built before recall N252494002. Before my ownership, the original engine failed and was replaced under warranty at 24,339 miles on 9/16/2024. The dealer verbally told me it was new, but it had salvage yard markings and no serial number—indicating it was used. This donor engine was likely from a vehicle later covered by the recall. GM appears not to track donor VINs for warranty replacements, meaning recalled engines can remain in service without repair. This creates a serious safety risk and allows defective engines to escape recall compliance. I urge NHTSA to require manufacturers to track and report donor VINs for used engines and major components installed under warranty so they remain subject to applicable recalls.

ENGINE
While driving the vehicle, the engine started to make a knocking noise and we experienced illumination of the check engine light. We also experienced engine performance issues with hesistation and reduced acceleration. We were able to take the vehicle to a GM dealer and it was determined that the lifters and crankshaft were defective and need to be replaced. There is a warranty out for 2021 GMC Yukon Denali vehicles that were manufactured less than a year after ours that have currently have a recall issued by GM for the same problems that we experienced. My wife and two young children, ages [XXX] and [XXX] , frequently ride in this car and catastrophic engine failures put their safety and livelihood at serious risk.
