“The turbocharger wastegate actuator failed suddenly at highway speeds, causing loss of engine power and making it extremely difficult to maintain highway speeds. The warnings that suddenly appeared caused the cruise control to cease working as well. The dealership (Audi Miami South by The Collection) inspected the vehicle and confirmed the wastegate actuator seized, requiring a complete replacement of the turbocharger. The vehicle has 53,000 miles.”
