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 2009 Porsche Boxster sits in the most stable period of its generation: complaints dropped from a spike of 19 in 2005 to just 3 in 2009, and the model had zero recalls in every year from 2005 through 2010. This represents a clear downward trend in consumer complaints following the relatively troubled early 2000s, which saw up to 34 complaints in 1998 and multiple recalls. By 2009, the Boxster had achieved its lowest complaint levels since the platform's launch, with no crash or fire complaints filed that year and only isolated tire and powertrain issues reported. The 2010 model year continues this pattern before a modest uptick in complaints and recalls appears in 2011-2017. The 2009 is among the best years to purchase within this generation—it falls at the trough of the complaint curve with no outstanding safety recalls.
