NHTSA (USA)High Risk

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.
The 2019 Mercedes-Benz AMG GLC43 has 8 recalls, the most serious being a roof panel that can detach from the vehicle and become a road hazard for other drivers.
Two separate roof panel concerns exist: one where the adhesive bonding on the front panel can deteriorate and cause it to separate, and a related issue where a prior repair may not have adequately re-bonded the panel, leaving the same detachment risk. On the occupant safety side, the passenger seat sensor can incorrectly show the front airbag as active when it is not, meaning a passenger would have no warning that the airbag will not deploy in a crash. The seatbelt pretensioners and the pre-crash tensioning system may also fail to activate during a collision, reducing how well the belts restrain occupants. Three recalls cover the automatic emergency call system: depending on the specific failure, the system can either stop working entirely so no call goes out, or it can send responders to the wrong location after a crash. There is also a label concern on the passenger sun visor, where the airbag warning may be printed in a foreign language, making the child safety instructions unreadable for most drivers.
