What Our Members Are Saying about Porsche Boxster Reliability and Durability

Reliability and Durability of the Porsche Boxster: Pros
YearBody/PowertrainComment
2005 2dr Convertible 240-horsepower 2.7L H6
5-speed shiftable automatic RWD
Consumer Reports rated it a Best Buy with better than average repair history. Owned for 3 years (bought new) and have had no major problems. Even for minor problems, if >1 day in the shop, they either gave me a loaner or a free rental car.
Reliability and Durability of the Porsche Boxster: Cons
YearBody/PowertrainComment
2008 2dr Convertible 295-horsepower 3.4L H6
6-speed manual RWD
prone to repair issues
2002 2dr Convertible 217-horsepower 2.7L H6
5-speed manual RWD
No complaints so far.Rumors of 2000 to 2008 motors have a 27 percent chance of blowing due to faulty design of a two piece crankshaft.However many ,many Boxsters have up to 175,000 on them
2002 2dr Convertible 217-horsepower 2.7L H6
5-speed shiftable automatic RWD
these cars have a history of not getting high mileage without having major engine problems. and the cost to rplce the motor is more than the value of the car after repairs. so far I have not had major problems myself.
