What's wrong?
The front passenger seat in the 2016 Mazda MAZDA6 includes occupant classification system wiring. That system identifies whether the front passenger seat is occupied and supports the air bag decision for that seat. The wiring runs near the seat frame, so it depends on intact insulation and enough clearance from sharp metal points.
On affected MAZDA6 vehicles, debris left from welding the seat frame can rub against the occupant sensor wiring harness. Mazda traced the problem to excessive weld spatter from variation in the manufacturing process. As the wire insulation wears through, the circuit can fault and turn on warning lights. The remedy part adds a foam pad that protects the wiring from the seat frame.
What you notice starts on the dash. Multiple warning lights in the instrument cluster illuminate. Some vehicles also lose power steering assist and have air bags deactivated, so those warnings need dealer attention.

What's the safety risk?
If the wiring is damaged, the MAZDA6 can lose power steering assist and the passenger air bag can deactivate, increasing crash risk and injury risk in a crash. Multiple warning lights in the instrument cluster are the warning sign. Schedule the recall repair soon, and avoid ignoring steering or air bag warnings. Repair is free at any franchised Mazda dealer.
What should I do?
- Check your VIN to confirm your 2016 Mazda MAZDA6 is included in this recall.
- Contact a franchised Mazda dealer to schedule the free OCS wiring inspection and seat-frame pad repair that protects the occupant classification wiring from seat-frame debris damage.
- Bring the recall notice if Mazda has mailed one. If not, reference recall number 17V546 when you call.
- Drive cautiously until the repair is complete. Be ready for heavier steering and ask the dealer about front passenger seat use before the repair.
What happens at the repair
At the dealer, a Mazda technician attaches a protective pad to the front passenger seat frame so debris cannot damage the occupant classification system wiring. If the OCS harness is already damaged, the technician applies insulating tape to the harness. The replacement work, parts, and labor are free under the recall. Mazda has a general reimbursement plan on file for documented out of pocket repairs tied to this issue. Bring prior repair paperwork to the service desk, or contact Mazda customer service about the claim path.
