Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 911.

Body PASSENGER CARTransmission Automatic (AM-S7)

The 2015 Porsche 911 is a high‑performance passenger car built on Porsche’s iconic sports‑car platform, powered by a naturally aspirated flat‑six engine that delivers impressive power and refined handling. Equipped with an AM‑S7 automatic transmission, it achieves EPA‑rated fuel economy of 20/28/23 mpg in city, highway, and combined modes. With only one recall that year and just eight total owner complaints—most centered on the electrical system, vehicle speed control, and engine—this model sits comfortably near the lower end of the 1990‑2014 complaint range, indicating a relatively reliable entry in the 911 lineage.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2015 model records only four total complaints across disparate systems—electrical, vehicle speed control/engine, service brakes, and structure—plus one fire complaint and zero crash-related complaints, marking a continuation of the minimal complaint volume seen in 2014 (2 complaints) and a dramatic decline from the 2007 spike (50 complaints). Unlike the 2007 model year, which generated an investigation and significant complaint volume, 2015 sits at the low end of the trend line with no recalls, investigations, or technical service bulletins indicated in the federal record for that year. The data shows no specified root cause for the single fire complaint or the electrical issues. Positioned after the 2007 volatility and alongside 2014’s subdued metrics, 2015 appears to represent a mature, stable point in the generation’s lifecycle with subdued federal scrutiny. This is a good year to buy.
