Over the weekend, the airbag light started going on intermittently - in the top left of the instrument panel. I couldn't figure out any pattern as to when it'd go on - sometimes at start, sometimes when driving, on and off every other minute, irrelevant whether solo or with a passenger in the right seat. So I called into the SC (Fremont) and got an appointment today. SC said "we've never heard of this one before!" - which, for Fremont, came as a surprise to me. Turns out after looking at the logs and diagnosing, there is a fault somewhere in the drivers seat sensor AND in the drivers seat belt sensor. Apparently this caused an intermittent warning that manifested itself in the airbag light. Solution: replace entire drivers seat and seat belt. The problem with this solution is, it's 10-14 days out of service (ugh!) because the seats and belts are all custom order depending on the config (I have P85, tan leather non-Sport) and the SC won't release a car with a seat belt fault. Good thing I'm not stuck in an Enterprise ICE loaner (today's loaner is a black S85, but no upgraded sound, bummer) No real complaints other than the time it's going to take to fix, but given that the SC said this is a really rare thing, I wanted to put the datapoint out there. I tried searching both this forum and TM's and couldn't find any complaints about airbag lights.
