One problem related to car will not accelerate has been reported for the 2012 Audi S4. The most recently reported issues are listed below.
Vehicle flashes a gearbox malfunction warning and most electronics went dead. Vehicle would not accelerate causing me to nearly be rear ended. After turning off car and restarting the vehicle continues to lose power randomly every mile or so. This created very unsafe conditions on a busy freeway. The problem turned out to be a faulty sensor in the transmission. Audi has issued a technical service bulletin on this issue but will not acknowledge the huge safety issue with this defective transmission.
