Known issues on the 2018 SL550. The federal record holds two recalls for the 2018 SL550. Certain cars were built with a front passenger air bag that might have been stitched incorrectly, allowing a seam to split as it inflates and reducing protection; dealers replace the air bag. Certain cars are also covered by a communication module software recall, because the emergency call system might report the wrong location after a crash. Air bag system diagnostics, restraint wiring diagrams and removal and installation procedures with their torque values are part of the manual.
