Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 SLS AMG.
The 2014 Mercedes SLS AMG is classified as a passenger car and represents the final iteration of the model’s short production run. Built on the same platform that underpinned the SLS lineage, it carries a powertrain that had been refined over the preceding years, while its safety suite—particularly the air‑bag system—registered the most frequent owner concerns, accounting for the sole category of complaints. With only two owner complaints recorded for 2014 and two recalls issued across the 2011‑2014 span, this year marks the lowest point in the model’s reliability record, indicating a comparatively mature and resolved engineering package for researchers examining the SLS’s durability trajectory.

From the factory this vehicle uses a BCI 48 · 760 CCA battery. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2014 Mercedes SLS AMG dominate in one area — the air bags, 2 of 2 reports (100%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the air bags pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
