2025 AUDI S5 Electrical System Problems

System malfunctions for new all new 2025 Audi S5 including drive system malfunction, loose wheel, brakes limited functionality, parking break malfunction, stabilization control malfunction, driving dynamics system malfunction, hold assist malfunction.

I began my lease for a brand-new 2025 Audi S5 on July 14, 2025. The vehicle was delivered with a dent in the door, which the dealer repaired before I could take possession. The dent repair was completed on July 22, 2025, at which time I took delivery. On July 23, I informed my sales representative that the SOS/eCall emergency communications system was not functioning. This safety feature, designed to automatically contact emergency services after a crash, has never worked since delivery. I returned the vehicle to the selling dealer on July 28, 2025. As of August 7, 2025, the vehicle remains in the dealer’s service department awaiting repair of the SOS module. No firm completion date has been provided. This defect means the vehicle cannot automatically summon emergency assistance in the event of an accident, creating a significant safety risk to occupants.
