A few years ago, our Subaru Forester had an open recall (WUM98-1) due to an issue with the passenger-side front airbag ODS, which caused the system to fail to detect a passenger, making it unsafe to drive. We had the recall repair completed at the time. However, about a month ago, the same airbag warning light came on again. After taking the vehicle in for service, we were informed that a different part (passenger front seat bottom assembly) now needs to be replaced due to code B1650. The dealership stated that this part is on a three-month backorder, leaving us with an unresolved safety issue. Since this appears to be the same underlying problem affecting the passenger airbag system, I am reporting it to the NHTSA to determine if other Foresters are experiencing similar failures. Additionally, this is an expensive repair, and I believe it warrants further investigation to determine if Subaru should take responsibility for addressing it.
