NHTSA Complaint #11696448 — 2021 GMC YUKON XL

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.
