Infiniti Q50 and Q60 engine may stall during acceleration

NHTSA campaign 21V234000 · Reported 2021-04-04 · Nissan North America, Inc.

high How serious is it? About this label

Serious — stalling while merging or accelerating can leave you without power in traffic; the notice does not tell owners to park the car, and the fix is a quick software update.

What's wrong, in plain English

The computer that controls the engine has a software problem on these cars. When it detects rapid acceleration, it can wrongly cut engine power and reduce the fuel going to the engine. Starved of fuel, the engine can stall. A dealer fixes this by reprogramming the engine computer with corrected software — nothing on the car has to be taken apart or replaced.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your car is included.
2. Call an Infiniti dealer or Infiniti customer service at 1-800-662-6200 and reference recall R20C5.
3. Have the engine computer reprogrammed — the repair is free.
