Got a letter from Subaru advising of recall for passenger seat occupant detection system problem in 2015-18 Forester.
Faulty connection may prevent recognition that passenger seat is occupied. Thus, passenger airbag will not inflate in a crash.
If seat is occupied but dash light says it ain't, you've got the problem. Don't ride a passenger there- put 'em in the back seat. If light is working accurately, you're OK.
Parts not yet available to fix it- at least in my area.
Stay tuned for more info...
