MX 100D (new 6/18) Had a new warning come on 2 days ago. "Blindspot Detection Limited (Camera visibility reduced)" When I engage autopilot the alert disappears but when I try to make a lane change another alert comes up " Auto Lane Change unavailable (Camera visibility reduced)". Cleaned all the cameras ( which didn't actually appear to be dirty) with no success. Rebooted several times which also failed. Called service who said they could see that the blindspot warning had occurred and had me set up a service appointment. (looks like mobile service in about a week). Has this happened to any one else? TIA
