Known issues on the 2019 SL550. Four recalls are on the federal record for the 2019 SL550. The most mechanical affects certain cars whose rear axle carrier could loosen over time at its front-left bolted mount, changing how the car handles; dealers inspect the joint, and an owner whose car is found defective is offered a buyback. Certain cars may also have a front passenger air bag with faulty stitching that can tear when it deploys. The other two involve the emergency call module on certain cars, one for SIM card software that can lose the mobile network and one for an inaccurate crash location. Rear axle torque values, suspension procedures and restraint diagnostics are covered.
