The dealer put the new software (version 502) on my CX-9 and now i get a maintenance warning every time I start the car. The warning doesn't even coincide with any scheduled maintenance. I had the oil and tires done at the same time and reset the schedule for those. I've even turned off the maintenance warnings yet it still appears when I start the car and it's apparently counting down to something. It does go away after a little while. Any ideas?
