2024 GMC Yukon XL: check engine light

Filed Oct 21, 2026 · Engine, Steering · KS

2024 GMC Yukon XL Denali with approximately 30,000 miles. The vehicle previously completed the L87 recall remedy (the federal safety agency 25V274000). The dealer inspected the engine, it passed, and the higher-viscosity oil change, filter, oil-fill cap, and owner’s manual insert were performed. Despite that remedy, the vehicle later experienced a sudden loss of propulsion on the highway while traveling with family. The vehicle began shaking and the engine shut down. There were no check-engine lights, warning messages, or other notifications prior to or during the failure. The vehicle was towed to a GM dealer. Diagnostic testing at the dealer confirmed that the engine requires replacement under Special Coverage N252494003. The dealer indicated the replacement engine will be remanufactured. The service department also confirmed that the vehicle had been maintained in excellent condition and that all recommended services were completed as required, so the repair is being covered by GM at no cost to the owner. The prior recall remedy did not prevent a subsequent sudden highway failure with no advance warning. Once the current repair is completed, the vehicle will carry a permanent engine-related entry on its history report at low mileage, which will affect residual value. This complaint is being submitted to document the post-remedy failure involving sudden loss of propulsion on the highway with no warning.

1.XXX XX— GM Recall Notification (Recall No. N252494000) I received official notification from General Motors of Recall N252494000 affecting my vehicle. I brought the vehicle to [XXX] as directed to have the recall remedy performed. 2. XXX — First Report of Engine Propulsion Issues I reported engine propulsion concerns to Jim Ellis. This was my first formal complaint regarding the performance of the vehicle following the recall remedy. 3. XXX — Oil Type Change Performed by Jim Ellis Jim Ellis performed an engine oil type change, switching to 0W-40 oil, and advised me that this change would serve as the fix for Recall N252494000. I accepted this remedy in good faith. 4. XXX — Low Oil Warning Light Activated Approximately nine months after the recall remedy, and well before the end of the recommended oil life cycle, the low oil warning light activated on my dashboard. This is abnormal and indicative of excessive oil consumption. I returned to Jim Ellis, who performed a fresh oil change and placed my vehicle on a 6,000-mile oil consumption test — an acknowledgment that an oil consumption problem exists. 5. XXX — Active Engine Misfires, Jerking, and Flashing Check Engine Light While operating my vehicle on Sunday, May 31, 2026, I experienced severe engine jerking and misfires. The check engine light began flashing — not steady — which I understand to indicate an active and serious engine misfire event. I was genuinely concerned for my personal safety and immediately parked the vehicle. It has not been driven since. 6. XXX — GM Corporate Case Opened I contacted GM Customer Care and was assigned Corporate Case Number INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Also everyday my vehicle keeps saying software update even I installed the update and it says complete. I know GM is not updating my vehicle software everyday. That indicates there is a computer issue as well. My anxiety level is through the roof at this point.

About 4 weeks ago my vehicle began shaking uncontrollably while driving. The check engine light illuminated and multiple warnings appeared including emissions system, variable valve timing system, engine and transmission failures shown on the GMC app. I contacted the selling dealership and was given an appointment 4 days later. Later that day I drove less than 5 miles to pick up my children from school. During that drive the vehicle filled with a strong gasoline odor and exhaust fumes were overwhelming. I feared the vehicle could catch fire. I contacted the dealership again, stated the vehicle was unsafe, dropped it off at approximately 8:00 PM and was required to obtain my own rental vehicle. After one week I was told the engine required a camshaft and lifter replacement. Inspected & approved by extended warranty, parts were ordered and installed. I retrieved the vehicle on 23 days after the initial failure. The following morning (24th day) while driving approximately 75 mph on a major interstate with my children the vehicle suddenly shifted into neutral and would not re-engage. I was unable to shift into any gear and coasted to a narrow shoulder inches from traffic and guardrail.The dashboard stated the vehicle could not shift into gear and instructed me to push the start button. The engine would not restart. We were stranded approximately two hours in 10-degree weather on a major interstate with heavy semi-truck traffic. Roadside assistance was required. 3 days later the dealership stated the failure was a fuse block. After replacement the vehicle was test driven and stated to be operating normally. A second dealership employee test drove the vehicle, it died again and had to be towed back to the dealership. The battery was replaced after draining while disabled. Repeated mechanical and electrical failures resulted in complete loss of power at highway speeds and placed my children and me in immediate danger. I no longer believe this vehicle is safe to operate.
