I am writing to formally file a complaint regarding a serious issue with my 2021 GMC Yukon XL, equipped with the 6.2L V8 gasoline engine and covered under Recall N252494000. The vehicle is experiencing significant power loss while driving, and the engine is making a loud clattering noise, which raises serious concerns about the vehicle’s safety, performance, and long-term durability. These symptoms are ongoing and have severely affected the drivability of the vehicle. Despite these clear issues, the vehicle recently passed a dealership inspection. In an effort to improve performance, a higher viscosity oil change was performed and a new oil cap installed. Unfortunately, these measures have not resolved the problem. The vehicle continues to run poorly and does not perform as expected from a vehicle of this age and mileage. I respectfully request the following: A thorough re-evaluation of the vehicle in relation to Recall N252494000. Immediate corrective action, including repair or replacement of any defective engine components. A detailed explanation of how the vehicle could have passed inspection with such evident performance and mechanical issues. Reimbursement for any out-of-pocket expenses incurred due to this ongoing problem.
