I am driving straight and on a level road. The light comes on/off two times and then stays off. I have driven 2 miles and the light goes off for good, even if I stop for ten minutes and then take off. If I stop for an hour or more, and then turn the car back on and drive away, I have no problem with the light going on. Also, the car sits in the garage for 5 days before I drive it again; sometimes a couple of months go by before I drive it.
The oil has no more than 2000 miles on it. I change the oil filter when I change the oil. Could the people who changed the oil did not change the filter?
