CarComplaints.com Notes: Mazda included the 2009 Mazda CX-9 brake booster in a special extended warranty (now expired) that covered 2007-2013 model years.
However, brake booster complaints never materialized as a defect trend for the 2009 CX-9 — both with our complaint data & with the NHTSA's complaint data. So, we highly recommend this 2009 model year!
Ratings only apply to the model and body or seat type tested. The date of manufacture and optional safety equipment can affect results. For full details see www.iihs.org.
