I was driving down the road and all of a suddenmy 2004 SRXwould not go over 25 mph. A message saying "Service Engine Very Soon" came on the nav screen. Also a single "2" (in the middle digit spot) replaced my odometer reading. Made it back home and shut off the car. Started a couple of hours later and the car worked fine. Any thoughts on what this might be? We just had the car in for the catalytic converter recall issue and they serviced the tranmission and differential unit.
