What Our Members Are Saying about the Reliability And Durability of the 2015 Mazda Mazda3

2015 Mazda Mazda3 Reliability And Durability: Pros
YearBody/PowertrainComment
2012 4dr Sedan 155-horsepower 2.0L I4
6-speed shiftable automatic FWD
It was neck and neck between the Mazda3 and the MINI COOPER. I had my heart set on the MINI, but reliability was the deciding factor. I spent countless hours researching vehicles over the last several months and was very dismayed at all the mechanical issues that plague the MINI. On the other hand the Mazda3 seems to be very much trouble free. I really wanted a MINI, but I knew its 'cool' fun to drive personality wouldn't be enough to overcome the reliability headaches I could expect. full 2012 Mazda Mazda3 review

Subaru is legendary for the durability & craftsmanship of the engine, powertrain, and vehicle frame. The interior may not be luxury, but that's fine by me. full 2013 Subaru Impreza review

Ultimately it was Subaru's predicted reliability past 50,000 miles that had us make our final decision between this car and a Volkswagen (Jetta or Passat). full 2012 Subaru Impreza review
