Known issues on the 2015 C300. Eleven recalls name the 2015 C300. In certain rear-wheel-drive versions a locknut inside the steering rack could snap under heavy load and leave the steering fixed in one position; dealers fit a new rack. Certain cars equipped with a panoramic sunroof may have had the front roof panel, between windshield and sunroof, bonded poorly during an earlier repair, so it could come off. Certain 4MATIC versions were recalled over a driver air bag that might deploy without warning. The 376 owner complaints concentrate on the engine (124), fuel and propulsion (66) and structure (59); 9 reported a crash, 4 an injury and 1 a fire. Steering rack procedures, engine diagnostics and torque values are in the manual.
