Known issues on the 2014 S550. Five recalls appear for the 2014 S550. Certain cars built between April and October 2013 may have a front seat belt anchor not fitted properly, so it could pull loose in a crash; dealers checked and corrected it. Certain cars built between August 2012 and August 2015 may have a power steering control unit with poorly soldered contacts that can cut steering assist while driving and, as contact resistance rises, create a fire risk even when parked and switched off.
