Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 2 tested variants for this model year.
The 2017 Mercedes-Benz AMG C63 has 11 recalls, the most serious involving a driver airbag that can deploy without warning, a rear axle differential mounting flange that can fracture and cause driveshaft failure, and a steering rack defect that can reduce the driver's ability to steer.
Several recalls relate to structural panels detaching from the vehicle: the front roof panel between the windshield and sunroof can separate and become a road hazard, and on Cabriolet trims, the rear beltline trim can also detach while driving. Both issues trace back to inadequate bonding, and one of the roof panel recalls specifically covers vehicles where a prior repair attempt did not fully resolve the problem.
Occupant restraint concerns appear across multiple components. Front seatbacks may not lock properly on one side and can fold forward in a crash, the front seatbelt pretensioners may fail to engage and leave occupants under-restrained, and the front seatbelts may not fully retract to their stowed position, making them awkward to use. The automatic crash notification system can also send emergency responders to the wrong location after a collision.
