Specs and fitment
Known issues for this generation
For 2016 C300 sedans, NHTSA lists campaign 18V-850: a locknut in the steering rack may break under load, so the car cannot be steered properly; dealers replace the steering rack. Campaign 21V-197 covers certain 2015-2020 C300 vehicles (with GLA, CLA, GLC, and other models): adhesive bonding of a front panel may deteriorate so the panel can detach; dealers reinstall the panel with approved primer and adhesive. Campaign 17V-627 also names C300 4Matic and related C-Class trims for driver-air-bag grounding. Unit counts on multi-model campaigns are shared across nameplates.
