“Since May 2024, I had taken my car in for repairs at 3 different shops for same exact issue diagnosed as leak from air intake system. It has been repaired 7 times since it first occurred in May 2024, and unfortunately it is still not resolved. This is a potential danger to the driver because all of a sudden there will be loud noise from the engine, car will start misfiring and slow down the speed. The previous 3 attempts of repair were made at Mercedes Benz of West Covina. The car is non drivable at the moment.”
