Mazda driver assist problems

Owners have filed 643 complaints with NHTSA about the driver-assist systems on Mazda vehicles — 2% of everything reported about the brand, across 18 models. The model that accounts for most of them is the Mazda CX-5, worst in 2018.

These are raw counts. A model that sold in millions appears near the top for that reason alone — the grade never compares one model with another.
