Air Bags:sensor:occupant Classification 2017-08-31 · campaign 17V546000 · 51,943 vehicles
Defect: 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.
Fix: 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.
