2021 GMC Yukon XL

While driving my 2021 GMC Yukon XL, the vehicle unexpectedly lost acceleration. After lifting off the gas pedal, it jolted forward, triggered a “Reduced Performance” dashboard warning, and remained in what felt like second gear, refusing to shift. I immediately pulled into a parking spot; when I attempted to reverse, the vehicle would not move backward. As you may imagine, this was a major safety concern, as I had my [XXX] and [XXX] children in the vehicle with me. I had the Yukon inspected at a GMC dealership, where a technician confirmed the issue originated from a faulty transmission valve body. My independent research has revealed this to be a widespread defect in the 2021 Yukon XL, prompting GM to issue Special CoverageXXX, which explicitly covers valve-body replacements for 2021 Yukon XLs experiencing reduced performance. Despite meeting these criteria and receiving identical diagnostic alerts, I was informed that my VIN is not covered. I am formally requesting that this safety-related defect—widespread among this model year—be recognized and my VIN included under Special Coverage XXX. The valve body causing the loss of propulsion in my Yukon XL is exactly the same defective component GM has acknowledged and is covering under this program.

I'm vehicle has experience both active recalls for similar model year but my VIN isn't listed as been one that is covered by the call. 25V274000 and 21V739000.

Low engine oil message keeps flashing after less than 2,000 miles of driver. Excessive oil consumption. Took vehicle to GMC dealership and it was confirmed that an engine replacement or replacement of the pistons and rings is necessary. Only 77,000 miles on the vehicle. My car is currently not a part of the massive recall.

Routine oil change by professional local mechanic. Upon completion we were told that the vehicle would not turnover. The mechanic diagnosed and found that were 2 recalls for our vehicle - one for the fuel pump module and one for the engine. We had our vehicle towed to the local GM dealership. They then replaced the fuel control module. GM tried to manually crank over but engine seized once again. We spoke to the GM Advisor prior to this and were told that our vehicle was not part of the engine recall because our VIN was not listed as part of it even though our vehicle had the same exact issues as described in the engine recall and was for the exact year/make/model of the engine. The dealer quoted us $14,896 to replace the engine. They stated they would submit a Goodwill claim to GMC to help discount the cost to repair/replace the engine. The dealer called back later that day and said GMC would be willing to cover 30% of the cost so our expense would be around $10,000. All this for a vehicle we've only driven for less than a year and a half. The vehicle went in for a routine oil change and has never had any issues prior to this. This happened suddenly without any sort of warning. To make matters worse, our powertrain warranty expired a day or two before this occurred. We are still trying to fight with GMC to cover this engine failure. The car has less than 75,000 miles and is only used for basic personal needs like driving to school and the store so it is shocking that the engine would suddenly fail like this and to make matters, the manufacturer refuses to take responsibility for it and to cover it under the recall even though there has been known widespread issues with this engine.

GM's 2021/2024 6.2 engine recall began with vehicle production March 1st, 2021. My Yukon XL Denali was produced Feb 26, 2021, THREE days before the recall start. The engine was replaced by GM approximately 6/21/2023 (previous owner), the replacement engine was built the 129th week of 2023. With my recent call to GM, they only reference the original vehicle's build date. If my vehicle missed that by three days, and now has another engine built during this recall period (2023), they have no help for me, it is NOT covered in this safety recall. Neither GM or my dealer has been able to tell me which oil to run 0w20 or 0w40. This vehicle's engine failed just outside of the current recall dates. With the expansion of dates, I can have my motor inspected and be covered under the extended year and milage warranty given to other owners. I am requesting NHTSA to expand the existing recall date. Thank you.
