The 2019 Mercedes-Benz SL 450 has 4 recalls, the most serious involving a bolt at the rear axle carrier that can fail over time, causing unexpected changes in handling and raising the risk of a crash.
The front passenger airbag carries its own concern: the airbag cushion may have been improperly sewn, and the seam can tear open during deployment, reducing the bag's ability to restrain the occupant and raising the risk of injury in a crash. The remaining two recalls both involve the vehicle's automatic emergency call system, which contacts emergency services after a collision. In one case, the system can send responders to the wrong location; in the other, the system may fail to connect at all, leaving occupants unable to summon help. Both conditions delay emergency response after a crash.
