Since shortly after purchase, the vehicle has experienced intermittent drivability and shifting issues along with repeated EPC and check engine warnings. Diagnostic trouble code P0111 (intake air temperature plausibility) has been present along with other electrical and engine management faults. A Volkswagen dealership diagnosis indicated that the intake air temperature sensor and an additional engine insulation “hood blanket” component (not originally installed on the vehicle) are required to address the issue. These components were presented as necessary to correct the fault and resolve intermittent shifting behavior. The shifting issue is intermittent but occurs during normal driving and raises safety concerns due to unpredictable drivability and transmission behavior. The vehicle continues to exhibit warning lights and unresolved performance issues despite multiple repair attempts. The dealership has not identified a clear root cause, and prior repairs including sensor and EVAP-related components have not resolved the condition. Given the involvement of transmission-related drivability concerns and repeated unresolved electronic faults affecting engine performance, I am filing this complaint as a potential safety-related defect affecting normal vehicle operation.
