VIN. See form above  In 2025, the engine coolant thermostat failed on my vehicle and required replacement at my expense. I am submitting this complaint because I believe this may represent a recurring component problem affecting 2019 GMC Acadia vehicles and I would like NHTSA to determine whether the condition presents an unreasonable risk to motor vehicle safety. General Motors has published service information addressing thermostat-related conditions on GMC Acadia vehicles equipped with the 3.6L engine. GM has also issued special coverage for an engine coolant thermostat condition on certain GM vehicles. GM’s special coverage describes a thermostat that can open at a lower temperature than intended, resulting in a malfunction indicator/check-engine light and diagnostic trouble code, and in some cases causing the engine cooling fans to continue running after the vehicle is shut off. My 2019 Acadia uses the 3.6L engine and the thermostat assembly addressed in GM’s service information. Despite this, my 2019 model year is not included in the current extended thermostat coverage. There is also a second, independent occurrence involving the same model year. My father owns a separate 2019 GMC Acadia, and the thermostat on his vehicle also required replacement in 2026. These are two separate vehicles that experienced thermostat failures requiring replacement. I understand that a thermostat failure is not necessarily a safety defect by itself. However, I am concerned that a recurring failure of this component could potentially create a safety risk depending on the failure mode and resulting vehicle condition. I am therefore asking NHTSA to review the available consumer complaints, manufacturer service information, warranty data, and GM special-coverage actions to determine whether there is a safety-related defect affecting 2019 GMC Acadia vehicles equipped with the 3.6L engine.","products":[{"type":"Vehicle","productYear":"2019","productMake":"GMC","productModel":"ACADIA","manufacturer":"General Motors, LLC"}]}]}
