POWER TRAIN
i had taken care of the recall items in regards to the failing 6.2L engine. I was driving on the highway (going ~70mph) when all of a sudden the car kicked into neutral and the engine shut off. I was able to pull over, but the engine would not turn on. Electronics worked, but I think i had a total engine failure at 42k miles.

WHEELS
I am submitting supplemental information regarding Complaint #11716907 involving a 2026 GMC Yukon XL AT4 equipped with the Brembo brake package. Following my original submission, GM's Executive Resolution Office provided written clarification of its disclosure position. GM states that the spare tire compatibility limitation associated with the Performance Brake Upgrade is disclosed through a hang tag affixed to the spare tire/wheel assembly mounted beneath the vehicle; and the owner’s manual. GM has not indicated that this limitation appears on the Monroney label, buyer’s order, or delivery documentation. The hang tag provided to me as an example states that the original spare tire/wheel does not fit the front axle when the performance brakes are installed. It instructs that, in the event of a front-axle flat, the consumer must install the spare on a rear wheel position & move a rear wheel to the front axle; and stow the flat tire. The spare tire is mounted underneath the vehicle. The tag is attached to the spare assembly and exposed to road conditions. In my case, when the spare was accessed following a roadside flat tire event, only a small piece of yellow plastic remained. Additionally, no printed owner’s manual is provided at delivery. During my roadside event, the dispatched service provider was unaware of any two-wheel rotation procedure and attempted to install the spare directly on the affected axle. The incompatibility rendered the spare unusable at that time. My concern is that current owners of vehicles equipped with the Performance Brake Upgrade may reasonably assume that a “full-size spare” is compatible with all wheel positions. Unless the undercarriage hang tag remains intact and is specifically read at the time of a flat tire, the incompatibility and required rotation procedure is not apparent. GM has not indicated it intends to notify new or existing owners regarding the spare tire limitation and required rotation procedure.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
On January 24, 2026, my wife was driving the vehicle we purchased in May 2025 from Ziegler GMC in Lincolnwood, Illinois. While traveling on the highway in WI the vehicle suddenly lost power without warning. She was traveling with our [XXX] son at the time and was able to safely maneuver the vehicle off the highway onto an exit ramp. Despite multiple attempts, the vehicle would not restart. She contacted me and arranged for a tow. We waited approximately four hours for roadside assistance before the vehicle was towed to the nearest GMC dealership, located roughly one mile from where the breakdown occurred. Several days later, the dealership completed diagnostics and informed us that the engine required full replacement. At that time, no replacement vehicle was provided. Approximately one week later, we were finally issued a loaner vehicle. As of today, the vehicle has remained in the shop continuously since January 24. On February 23, we were informed that the necessary parts had only just arrived. There is still no estimated completion date for the repair. The vehicle is covered under both the manufacturer’s warranty and an extended warranty. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES
The ABS system in this vehicle and many other similar GM vehicles of this year have abs pumps that malfunction and/or randomly stop working just to begin working later. My vehicle currently has the abs fuse removed because whenever it’s in the abs pump runs continuously even when the vehicle is off. The vehicle I own is in good shape with only 80,000 miles. similar gm vehicles of this age with more miles have even more issues specially with the abs system it’s worse in vehicles that also come equipped with traction control.

POWER TRAIN
The contact owns a 2021 GMC Yukon XL. The contact stated that while his wife was driving approximately 30 MPH, the vehicle started to lose motive power with the message "Service Transmission Now" displayed. The driver was unable to shift the vehicle into reverse(R) and turned around and returned to the residence. The contact and his wife researched online and found that there was a recall for the transmission for the year and model under NHTSA Campaign Number: 24V797000 (Power Train). The contact had the vehicle towed to a dealer, who diagnosed the vehicle and determined that the transmission valve body had failed and needed to be replaced. The contact discussed the recall and was advised by the dealer that the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 70,000.

ELECTRICAL SYSTEM:INSTRUMENT PANEL:SPEEDOMETER/ODOMETER
Odometer Fraud. The contact purchased a 2003 GMC Yukon XL. It was later discovered that there was a mileage discrepancy. The vehicle was a dealer sale on January 26th, 2026. At the time of purchase and at the time of the vehicle registration, the vehicle mileage was 186,000. While applying for insurance on February 20, 2026, the contact was informed that the vehicle was due for a 300,000-mile maintenance plan. The contact confirmed through the Carfax Report that the actual mileage was 300,000. The dealer was contacted and informed of the odometer fraud discovery; however, the dealer refused further contact to resolve the issue. The odometer fraud was also reported to the State Consumer Protection Division.

I experienced complete engine failure at around 76000 miles similar to a current engine recall for 2021 to 2024 6.2L V8 engines. However, my engine isn't included in the current recall. I also experienced the fuel pump control module problem requiring replacement. Again there is a recall for 2021 to 2024 6.2L V8 engines and again my engine wasn't included in this recall.

ENGINE
My 2020 GMC Yukon XL Denali 6.2L with 59,000 miles developed a ticking noise and slight power loss diagnosed by three different garages as a "collapsed lifter" on #4 cylinder. It's one of the AFM/DoD cylinders that shuts down to save fuel. $8,000 repair estimate, or $12,000 if the failed lifter damaged the camshaft. All three garages said "we see a lot of these." Internet forums are loaded with lifter problems on this engine: specifically AFM/DoD lifters. Safety is not affected. Noise/diagnosis reproduced by three independent garages. Has not been inspected by mfg, police, or insurance rep. No warning lamps or messages, no ODB2 "codes" found by garages. Seven months ago the water pump exploded on Interstate 70, putting us at serious risk. Now this lifter trouble at 59,000 miles. Both should have been covered by the 60,000 mile powertrain warranty, but I'm beyond the 5-year limit.

Complete engine failure while driving on I25 in New Mexico, lost all power was able to roll into a airport parking lot. If I had not been close to the off ramp it could have been catastrophic with the truck traffic on the Interstate. The vehicle has completed all of its normal maintenance on time, and as of January 30, 2026 had a complete review from GMC that everything was in great shape including the engine. There was never a warning light, a maintenance message or any other indication.

ENGINE AND ENGINE COOLING
The contact owns a 2024 GMC Yukon XL. While the contact's wife was driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. In addition, the contact's wife noticed an abnormal knocking sound before the engine seized. The check engine warning light illuminated. The vehicle was towed to the dealer, where it was diagnosed and DTC: P0305 (lifter on cylinder 5); was retrieved, and the intake valve detached and damaged the camshaft. The contact was informed that the lifters and related parts, camshaft, and the coolant pump needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer where it was diagnosed with engine failure due to the metal shavings found in the oil. The contact was informed that the engine needed to be replaced. The vehicle was not diagnosed. In addition, the failure had occurred within 2,500 miles of the initial repair. The manufacturer was made aware of the failure ,and a case was filed. The failure mileage was approximately 14,589.
