This page covers 11 recalls and 13 owner complaints for the 2018 Mercedes-Benz Amg C43.
Complaints for the 2018 Mercedes-Benz AMG C43 are thin at 13 total, so patterns are limited. The clearest cluster involves wheels, which draw the most reports, though the representative narratives provided don't detail what owners describe happening there. Structural complaints include a handful of convertible soft-top issues: owners report the rear window bond failing and beginning to detach from the top, with hairline cracks appearing at the separation points, and interior soft-top cords snapping, fraying, or pulling free during roof operation. A couple of owners also describe panoramic sunroof problems, including a loud thump when closing and, in one case, the glass shattering unexpectedly while driving. A single report mentions front seat belts not fully retracting to their stowed position.

Total Complaints
By System
The 2018 Mercedes-Benz AMG C43 has 11 recalls, the most serious being a roof panel that can detach while driving and become a road hazard, and a driver airbag that can deploy without warning.
Several recalls involve the front seats. The seatback locking mechanism on the front seats may not secure properly on the right side, which can cause the seatbacks to fold forward in a crash. On vehicles equipped with AMG performance seats, the backrest rail and fitting may not be correctly welded, which can also cause the seat to collapse in a crash. These seat concerns cover both driver and passenger positions.
On the airbag side, the passenger seat sensor can incorrectly show the front airbag as active when it is actually off, leaving an occupant unaware they have no airbag protection in a crash. The automatic emergency call system can also send responders to the wrong location after a collision.
A few body and chassis concerns round out the list. On Cabriolet trims, the rear beltline trim can separate from the car and become a road hazard. A loose 12-volt battery mounting bracket can let the battery shift or detach in a crash, cutting power to hazard lights and emergency communication. The front seatbelts may also fail to fully retract, which can discourage consistent use.
