Every time I start my MDX the Check Engine light flashes for a few seconds. Then it goes away. Should I be worried? I don't really remember when it started happening but it was a while after I got my oil changed at the dealer.
It is normal. The dealer forgot/could not reset the reminder for the scheduled service. Mine is doing the same right now. The manual describes how to reset it.
A2 -- your answer sounds like it relates to the Service light, but the question was regarding the Check Engine light. Not sure the Check Engine light should flash, but may depend when you see it. A lot of the lights come on when your first start up.
Actually, it'd the Maintenence Required light not the Check Engine light. Every time I start the MDX it flashes about 5 or 6 times and then it goes away.
