What's wrong, in plain English
Mercedes-Benz is recalling certain electric and plug-in models, including the EQS SUV and S-Class. These vehicles have a system that makes an artificial sound outside the car so that people nearby can hear it coming. A software problem can make the car play the wrong sound while it is backing up, which means the vehicles do not meet the federal rule on minimum sound for hybrid and electric vehicles. Dealers will update the software free of charge.
What you should do
2. Contact a Mercedes-Benz dealer, or MBUSA customer service at 1-800-367-6372 (recall number 2025070005), to book an appointment.
3. Have the dealer update the sound system software — the repair is free.
