Of course it ends up being the driver's decision and it can be a major one. I'm thinking if the SES light is blinking, that's a sign to stop at a mechanic ASAP (and be very careful about driving at all en route). Since the light is solid, it's something to check as soon as convenient (which in this case is in another ~300 miles). I'll look into checking SES code also. | |
