I think that I am going to have the guy at the autoparts store try to reset it and see if it comes back on. If it does, I will worry about it then.
I have 50k miles on it and it just had the 48k mile maintenance on it right before I bought it. When I got it it had 47,600 miles on it. I bought it certified pre-owned from a dealer right after the 48k maintenance was performed. I'm hoping that the reason the lady got rid of it was only because of the lease ending and not because they found all kinds of problems when doing the scheduled maintenance!
