Takata recall - took vehicle in for takata recall with no issues with vehicle. Picked it up after "repair" only to find airbag light on. Made appointment to bring vehicle back in and now being told that there is a passenger occupancy sensor that has gone bad. They claim this issue does not have anything to do with the recall!! after researching online, I find complaint after complaint concerning this very issue. This sensor should be included in a recall as there is obviously a defect with the sensor with so many complaints about it. And it is a high dollar fix.
