I moved safely to the shoulder, but the vehicle became inoperable and required towing. The loss of propulsion in active highway traffic created a potentially hazardous situation.  My GMC Bommarito Buick GMC dealership advised that GM cannot currently supply the required replacement transmission. The dealer has no estimated delivery date and does not know when GM can supply the unit. The vehicle has been out of service for over four weeks, with no definite repair or return-to-service date.  I am concerned that the inability to provide a replacement transmission may indicate unusually high demand or a broader issue. I identified other recent NHTSA complaints involving 2020 GMC Yukon XL vehicles reporting 10-speed transmission failures and difficulty obtaining replacements, including ODI complaints 11711773 and 11747021. I request that NHTSA evaluate this complaint with similar reports.  I respectfully request that NHTSA consider whether: \u2022 These transmissions are experiencing premature or unusually frequent failures. \u2022 Valve-body, internal, or other component defects may contribute. \u2022 Failures can cause sudden loss of propulsion, unexpected shifting, loss of power, or other safety-related conditions. \u2022 The replacement-transmission shortage is connected to an unusually high failure rate. \u2022 GM has sufficient replacement units and repair components available. \u2022 Available complaints, dealer information, and manufacturer information warrant further investigation or action.  I request that this complaint be associated with my VIN and reviewed with other complaints involving 2020 GMC Yukon XL Denali vehicles and other GMC, Cadillac, and Chevrolet models equipped with the 10-speed 10L800-speed automatic transmission. I believe the circumstances warrant review as a potential broader vehicle-safety issue, rather than solely an individual parts-availability problem.","products":[{"type":"Vehicle","productYear":"2020","productMake":"GMC","productModel":"YUKON XL","manufacturer":"General Motors, LLC"}]}]}
