NHTSA's VIN data lists these trims for the 2016 Mazda6. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 77 complaints with NHTSA about the 2016 Mazda6. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

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 2016 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.
Air bags: sensor; Seats; Steering: electric power assist system
Mazda North American Operations (Mazda) is recalling certain 2016 Mazda6 vehicles. Debris from the welding process during manufacturing of the front passenger seat frame may damage the occupant classification system (OCS) wiring.
Risk: If the wiring becomes damaged, there may be a loss of power steering assist and the deactivation of the passenger air bag, increasing the risk of a crash and the risk of injury in the event of a crash.
Remedy: Mazda will notify owners, and dealers will attach a protective pad on the seat frame. If the OCS harness is damaged, insulating tape will be applied to the harness. These repairs will be performed free of charge. The recall began October 26, 2017. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 1517H.
Carmakers sent NHTSA 670 service bulletins and notices that cover the 2016 Mazda6, the latest on Sep 11, 2026. They tell dealers how to fix known issues.
The parts they mention most: equipment (220), electrical system (183), engine and engine cooling (58), engine (51), power train (50).
NHTSA hasn't opened a defect investigation that covers this model year.
