Fuel pump may leak fuel or stall, risking fire or crash
The fuel delivery module in these vehicles may not be properly secured to the fuel tank, so its locking plate can loosen and allow fuel to leak.

Certain 2015 Mercedes-Benz C300 and C400 vehicles built from June 18, 2014, through September 5, 2014, were assembled with horizontal adjustment mechanisms in the headlamps that an owner can turn, instead of the proper sealing caps.
