2011 Porsche 911

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 911.

Body PASSENGER CARTransmission Automatic 7-spd

The 2011 Porsche 911 is a passenger-car model fitted with a seven-speed automatic and EPA-rated fuel economy of 19/27/22 mpg. Across the 1990–2014 complaint record, this model year generated only two owner complaints and two recalls, placing it near the lowest end of the historical range and well below the 2007 peak of fifty. With its reported concerns concentrated in engine and engine cooling, that minimal volume positions the 2011 911 among the most reliable years in the documented span.

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 provided federal record highlights a significant anomaly in 2007 with 50 complaints, contrasting sharply with the generally low volumes seen from 1990 through 2001 and the 2 complaints recorded in 2014. For the 2011 target year, specific data shows only one complaint each in Engine and Engine & Engine Cooling categories, with zero crash or fire complaints reported. This positions the 2011 model within the lower-complaint segment of the available data arc, resembling the 2014 profile more closely than the 2007 spike. Although the year-by-year array does not explicitly list a total complaint or recall count for 2011, the targeted metrics imply a return to baseline reliability following the 2007 peak. Given the lack of safety-related incidents and minimal engine complaints relative to the 2007 outlier, this represents a statistically stable year to purchase within the provided dataset.
