What can fail
The front roof panel between the windshield and panoramic sunroof may have been improperly bonded during a prior repair, causing the panel to detach from the vehicle.
This page covers 10 recalls and 23 owner complaints for the 2017 Mercedes-Benz Amg C43.
Seat belts are the clearest theme in what owners of the 2017 Mercedes-Benz AMG C43 report. Multiple owners describe the front seat belts, both driver and passenger side, failing to retract after being unlatched, leaving the belts hanging loose rather than retracting to their stowed position. No warning light typically accompanies the problem, and some owners report the issue affecting both front positions simultaneously. Wheels are the second most-reported system by volume, though the available narratives don't detail specific symptoms clearly enough to characterize a pattern there. A small number of seat complaints and an isolated report of a rattling sunroof glass round out the complaint set. The non-retracting front seat belt issue is the most consistently described problem across multiple owners in this model year.

Crash-Related
By System
The 2017 Mercedes-Benz AMG C43 has 10 recalls, the most serious being a front roof panel that can detach from the vehicle while driving and a driver airbag that can deploy without warning, both raising the risk of a crash or injury.
Several structural body recalls affect exterior panels: the front roof panel between the windshield and panoramic sunroof can separate from the vehicle if its bonding fails, and on Cabriolet variants, the rear beltline trim can also pull away and become a road hazard. Two overlapping recalls address front seat seatbacks that may not lock properly on the right side, meaning the seat could fold forward in a crash. The front seatbelt pretensioners on certain vehicles may not fire correctly in a crash, leaving occupants less restrained than they should be, and the front seatbelt retractors on some vehicles may not fully retract, which can discourage occupants from wearing the belt at all. On the steering side, one specific vehicle in this group has a power steering control unit where a connection can fail and cut off steering assist entirely, requiring noticeably more effort to steer. The automatic emergency notification system, which is meant to call for help and relay the vehicle's location after a crash, can send responders to the wrong location.
