ECM may cut power and fuel after hard acceleration (2021 Q50 and Q60) (2021)
ModerateOn certain 2021 Infiniti Q50 and Q60 models, which EPA lists only with the 3.0-liter twin-turbo, the engine control module can wrongly reduce engine power and fuel supply after detecting rapid acceleration, which can stall the engine. Dealers reprogram the ECM software free of charge.[15][16][17]
Symptoms
- Sudden loss of power after hard acceleration
- Engine stall
Check before buying
- Run the 17-digit VIN through NHTSA's recall lookup and confirm the remedy shows as complete
- Ask an Infiniti dealer for the record of the ECM reprogramming (Infiniti campaign R20C5)
Program: NHTSA safety recall 21V234 (free ECM reprogram at Infiniti dealers)
