NHTSA complaint #11394282, filed 2021-02, 110,000 miles“I own a 2005 Mercedes-Benz C320 for three years and always have issues with the software, the engine keeps shutting off while driving, and the steering wheel get locked, no matter where I am at, a city streets or a highway. Many phone calls to Mercedes-Benz dealer and the headquarter, they didn't try to resolve the issues I'm having with my car!!! Mercedes-benz wants people either forget about the safety issue! Die naturally or sell their cars.”
