How reliable is the Mazda Mazda6? What NHTSA's records show
We don't give the Mazda6 a reliability score. NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. Here is what's on file for model years 2010 on.

Every model year compared
Complaints rise with how many were sold and how long they've been on the road, so a newer or rarer year will show fewer. Compare years of the Mazda6 with each other.

Common questions
Is the Mazda Mazda6 reliable?
We don't score reliability: NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models.

The model years with the most complaints are 2010 (225), 2014 (137), 2011 (135). Whether a known problem was fixed on one car is what its service records show.
What are the most common problems with the Mazda Mazda6?
Across every model year since 2010, owners' complaints to NHTSA most often name other or unspecified (16%), airbags (14%), electrical system (14%). Mazda has filed 8 warranty extensions covering the Mazda6, listed on this page.
Which Mazda6 model years have the most complaints?
2010 (225), 2014 (137), 2011 (135). Complaint counts rise with how many were sold and how long they've been on the road, so compare years of the Mazda6 with each other rather than with other models.

Yes: engine (model years 2018–2021); other or unspecified (model years 2016–2021); engine (model years 2018–2020), and 5 more. A dealer does a covered repair for free within the extended time or mileage.
