2005–2011

Model years affected

This generation's Takata airbag recall shows both extended parts-unavailability delays (many owners reporting 1-2+ years without remedy) and an unusual added cost: one owner reported being charged $1,640 in shipping fees just to complete the supposedly free recall repair. Separately, steering column lock failures while driving are also reported on the Infiniti M35/M37, and camshaft chain tensioner failures are also reported on the Audi A4.
