Source-backed problem files
Documented Mercedes-Benz C-Class conditions
Higher safety relevance appears first. The order does not measure reliability.
2015 to 2018 Mercedes-Benz C-Class · Safety restraints
Air bag may deploy unexpectedly
The driver's air bag may unexpectedly deploy due to insufficient grounding of the steering components if an electrostatic discharge occurs and the air bag clockspring is broken.
2022 to 2023 Mercedes-Benz C-Class · Body & structure
Door may open or fail to latch
The micro-switch in the driver's door lock may corrode and fail to detect an open door, preventing the electronic parking brake or "Auto-Park" feature from engaging automatically.
2025 to 2026 Mercedes-Benz C-Class · Electrical & software
Electrical or software fault may disable vehicle functions
The infotainment control unit may reset while the vehicle is in motion and cause the instrument panel display to go blank.

Electrical or software fault may disable vehicle functions
The software design of the communication module may fail to communicate the correct vehicle location for the emergency call system (eCall) in the event of a crash.
2022 to 2025 Mercedes-Benz C-Class · Safety restraints
Seat belt may not restrain an occupant
The driver-side seat belt cover may not be properly installed on the seat belt tensioner, which can cause the seat belt anchor to come loose.
Before diagnosing the Mercedes-Benz C-Class
Use the right check before buying a part
A symptom can have several causes. These guides help separate a useful clue from a diagnosis that still needs testing.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
Read guide ↗Words owners use

Choose the description that sounds closest, then read the complete symptom pattern.
