Known issues on the 2014 SL550. NHTSA records four recalls for the 2014 SL550, and two concern air bags. Certain cars built during a short production window may have a front passenger air bag assembled incorrectly, so it might not deploy properly, while certain others needed control unit software updated because the air bags might not deploy as intended. A third recall targets poorly soldered contacts in the electric power steering control unit on certain cars assembled within a set multi-year production period, risking lost assist and a fire. Four owner complaints name wheels (2), air bags and structure. Restraint system diagnostics, steering control wiring diagrams and wheel specifications are in the manual.
