Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2017 Mazda6 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Mazda North American Operations (Mazda) is recalling certain model year 2017 Mazda6 vehicles manufactured August 12, 2016, to September 28, 2016 and equipped with optional accessory fog lights. Due to an incorrect combination switch being installed, the turn signals may not automatically cancel by the rotation of the steering wheel. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: A vehicle continuously driven with the turn signal flashing may result in confusion to other drivers, increasing the risk of a crash.
Remedy: Mazda will notify owners, and dealers will replace the combination switch, free of charge. The recall began December 2016. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 0316J.
Carmakers sent NHTSA 516 service bulletins and notices that cover the 2017 Mazda6, the latest on Sep 11, 2026. They tell dealers how to fix known issues.
The parts they mention most: electrical system (172), equipment (158), engine and engine cooling (52), power train (42), unknown or other (41).
NHTSA hasn't opened a defect investigation that covers this model year.
