In February, Nissan initiated an investigation into reports of an illuminated Malfunction Indicator Lamp (MIL), reduced power and engine stalling in some 2021 Infiniti Q50 And Q60 vehicles. This investigation has resulted in a recall affecting approximately 13,000 vehicles.

According to the defect report, the engine control module (EMC)in the subject vehicles has a software function that prevents unintended acceleration based on monitoring torque input. A problem was found with the EMC software which prevented it from correctly reducing engine speed after an excessive torque detection. As a result, the vehicle would go into limp mode, reducing engine power, illuminating the MIL and eventually stalling. Nissan has received one report of an accident without injuries potentially related to this issue.

Infiniti will be notifying owners to return to their dealerships to get the ECM software reprogrammed. Infiniti’s number for this recall is R20C5 and the NHTSA campaign number is 21V-234.
