On certain vehicles, there could be a problem inside the high-voltage battery. As a result, the battery modules could overheat and short circuit.
Safety Risk
A short circuit in the high-voltage battery can create a fire risk.
Corrective Actions
Audi will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the high-voltage battery modules. To reduce the safety risk, Audi recommends that you set the maximum charge setting of your vehicle at 80% until the recall repairs are completed.
