'10 Focus: passenger air bag
 

I have a 2010 Focus and the passenger air bag light often lights up. This is when I have a passenger and no passenger in my car. Sometimes it will go off after a few seconds, other times it will go off after a few minutes. There doesn't appear to be a rhyme or reason for this, but maybe there is that I'm not aware of. I bought the car in late August. Should I have it looked when I get my first oil change? Thanks.

I would have it looked at soon. It could disable the supplemental restraint system. (airbag)
