Has this repeated for more than one day or more than one ignition cycle?

Do you have a GAP tool to look for codes?

What model year is it?

Happened to me after driving thru nasty storm. Didn't go away for a couple of days and then disappeared. I checked radar and it was clean and not flooded, it almost felt like image detection software crashed due to storm.

Thats funny you mentioned you drove through a nasty storm. I'm in Naples Florida and we are having epic rainfall. One thing I've experienced with two of my D90's is that they do NOT like water.....which is ironic considering they can tread through 2'-11" of water with suspension raised to off road height.

The first problem I encountered many months ago during heavy rain was that I could not back out of a parking spot during a downpour, when I engaged R and tried back up the brakes would instantly engage. Had to leave the vehicle there over night.

The second problem I have when it rains is wiper blades that chatter or skip BAD on the down stroke, really bad.

The third problem is this newest issue described today.....

I hear ya......I normally would love to disable all of this "safety" crap, but when it disables itself and gives me warning messages....thats when I post here.

Unfortunately nobody makes blades with the channels that JLR uses. If you find something, let us know... The blade likely will work, but the spray will only spurt out of the base.

I usually get that message when driving in a snowstorm with snow and ice accumulating on the front. Guessing something blocked the front camera or sensors?
