The two times I had my CMBS light on with my 11 MDX Adv was when it was blocked with snow/muck during winter. I had to pull over and clean off the plastic cover inside the grill. Sound like it could be a failure/error with the CMBS radar? There should be a button on the dash to disable the CMBS (not sure if CMBS will stay off when you restart the MDX). The CMBS may not be working properly? You might need to take extra caution without having that feature active. Pressing/holding the ACC range button on the steering wheel will switch to regular cruise control if you notice the ACC isn't adjusting range properly with traffic.

I cleaned outside screen on sensor and no fix. I also turned off button on dash and it clears for a second and then goes back to orange Check CMBS. I also had ACC warning but it no longer is lite. Happened immediately after my wife closed rear hatch at airport.
