4 recalls across 3 model years
The Mercedes-Benz SL 450 has 4 recalls covering 2018–2020 model years, with the most serious affecting 2019 vehicles where a bolt at the rear axle carrier can fail over time, causing unpredictable handling changes that raise the risk of a crash.
On the safety equipment side, 2018–2019 models have a front passenger airbag with a seam that can tear during deployment, reducing the bag's ability to cushion the occupant in a crash. The 2018–2020 model years are also covered by two recalls related to the automatic emergency call system: in one, the system can transmit an incorrect location to emergency responders after a crash, and in the other, the system can fail entirely, preventing any call from reaching emergency services. Both issues delay help reaching the vehicle after a collision.
