Audi A4 And Q5 - Short Circuit In ECU May Cause Engine Stall

On 2022-06-10 08:21:36

Volkswagen Group of America (VW) will be contacting the owners of certain Audi Sedans and SUVs because of a problem affecting the engine control unit (ECU) in their vehicle. The problem could lead to an engine stall and an increased risk of an accident.

The vehicles affected by this problem include:

2022 Audi A6 Sedans
2022 Audi A4 Sedans
2022 Audi Q5 Crossover SUVs
2022 Audi Q5 Crossover Sportback SUVs

Audi first learned of the problem in February 2022, when they were contacted by their supplier of ECUs regarding a problem affecting a small number of units. According to the defect report, some ECUs could contain semiconductors that were not built according to manufacturing specifications. A defective semiconductor inside the engine control unit could short-circuit and cause the engine to stall.

Audi immediately stopped their vehicle production line that could be affected by the problematic engine control module, but a small number of units may have been installed in certain 2022 Audi A4 and Q5 vehicles. The Audi Product Safety Committee decided that a safety recall was necessary, due to the potential of an engine control unit failure while driving.

Audi is aware of one (1) warranty claim in the United States with an engine that would not start because of this issue.

Owners receiving notices will be asked to return to their dealerships to have the engine control unit replaced. Audi's number for this recall is 24iH and the NHTSA campaign number is 22V-377.
