The 2012MERCEDES-BENZAMG SLS carries 4 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2012 AMG SLS is fuel/propulsion system with 2 filings, followed by fuel system, gasoline:delivery:fuel pump:mounting plate/flange (1) and unknown or other (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 15 investigation files overlapping the 2012 AMG SLS. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

THE CAR HAS NEVER BEEN IN ANY ACCIDENT OR SUBJECTED TO ANY TYPE OF SEVERE JOLTS OR BUMPS ON NATIONAL ROADS.
WE HAVE A 2012 MERCEDES AMG SLS THAT IS A COLLECTOR'S CAR WITH ONLY 5000 OR SO MILES ON IT. IN THE LAST 5 YEARS, I THINK IT HAS BEEN DRIVEN ONLY ABOUT 2500 OR SO MILES BY US. EVEN THOUGH WE PUT VERY FEW MILES ON THE CAR EVERY YEAR, WE STILL GET AN ANNUAL SERVICE DONE. THIS YEAR WHEN WE TOOK THE CAR BACK HOME FROM THE DEALER'S SERVICE DEPARTMENT, WE NOTICED A VERY STRONG ODOR OF GASOLINE. WE TOOK THE CAR BACK TO THE DEALER AND THEY DISCOVERED THAT THE "SENDING UNIT" OF THE FUEL SYSTEM WAS CRACKED. THIS RESULTED IN THE PASSENGER CABIN OF THE CAR GETTING SOAKED IN GASOLINE, AS NOTED IN THE ATTACHED INVOICE. THE DEALER SAID THIS IS A MAJOR SAFETY HAZARD, AND THAT WE WERE VERY LUCKY THE CAR DID NOT CATCH FIRE.
