“Radar Comm Failure” Alert!!
I have a 2020 Winnebago Horizon 42 Q on the Freightliner Chassis.
Bought new March 2020 with 28,000 miles on since purchased
Heading to Florida the day after Christmas I get a big bright alert overlying my Digital Speedometer “RADAR COMM FAILURE” with 2 idiot lights.
Lucky I was stopping for fuel, called Freightliner 24 hour hot line.
He told me it was my Adaptive Cruise and Collision Avoidance unit, it lost communication with the sensors. I told him I don’t have Adaptive Cruise and Collision Avoidance on my unit. He looked up my VIN a and said that my dash was reflashed in March 2020 to remove that software. I said it’s there now!
So he said no problem bring it in to reflash the dash software when I can.
Lucky me it didn’t affect my 2500 mile trip but I had to look at the alert and the idiot light for the last 2000 miles.
I just thank god it didn’t shut me down.
I still can’t figure out why it shows up 2 yrs and 28,000 miles later.
