I purchased a 2020 XX60 ProActiv about 9 months ago and am having a problem with the intelligent cruise control (ICC) and front collision prevention systems. When driving on a highway with the ICC engaged, and after not detecting a vehicle in front for 3 to 20 minutes (variable) an alert appears indicating the front radar is obstructed or unavailable, disabling both the ICC and front collision prevention systems. The error message will reset after 25 to 30 minutes (warning light and error message will turn off), after which I can restart cruise control and re-enable the ICC. This will occur repeatedly. The vehicle has been inspected by the dealer but they are firm that this is normal. I find this hard to believe as I have driven many other vehicles with ICC systems without this problem. Has anyone else experience d this?
