On the 26th day, after almost 6000 miles of driving, the first significant rain occurred at night in Kansas. AUTO ceased to be effective. Light rain brought on fast; heavy rain ran the intermittent mode. Splashback brought the wipers to stop totally. I took it in only to be told that there were still programming issues. NOW THEY TELL ME!!!
Obviously, I ended up using manual mode, but it was not helpful on the interstate when it is pitch black and the lines in the road cannot be seen. Having to work the screen to get the wipers to operate as needed, was, of course, not helpful. The lane change "shaker" did not work. After driving 6000 miles, I was exhausted and not in any mood to have to "learn" how to drive and control the wipers.
