Here's a weird one. The rain sensing wipers on intermittent setting go on as expected then keep speeding up after a while (5-10) minutes until they are going max speed or I turn off and restart them. Not a big issue but you would think this tech would work properly - not like it's anything new. Funny gremlins.

It isn't normal and you may have a bad sensor, or the area of the windshield where the sensor is has obtained a coating of something that is making the sensor go mad. Wax coating or bug remains on the outside of the windshield in the area of the review mirror and cameras?

FWIW, I've had this issue in my 2004 Touareg; the sensor fogs up, which sets it off to the max, which automatically increases the wiper rate to the max. I've also had it happen in my first I-Pace when it was humid and cold, so perhaps it's really about condensation. Not 100% sure on this though.

The rain sensing wipers on my I-Pace might be the worst rain sensing wipers I have ever had. They are way too intermittent and allow to much rain to build up on the glass between swipes. I either use them on a set speed, or I do a lot of 1 touch of the stalk manual wipes.

You can adjust the sensitivity the same way you'd adjust the intermittent rate by rotating the collar on the stalk that has then MIN and MAX markings.

Yes, I have done this. It still makes little to no difference. Luckily where I live in So. Cal, we can go 9+ months with never needing wipers ;)

Same here. I have had RS wipers on Porsche, BMW and Mercedes, even Hyundai. These are the worst ever. No excuse for problems with technology that old and that common.

My rain sensing wipers always come one when I go under the new Fastrak cameras on the 110 Fwy just before it ascends into it's own separate lanes. Why?!?!

Is that at night or during the day also? I think the cameras use infrared illumination, and the rain sensor is based on infrared refraction if I remember correctly.

Bad sensor
That's what I hope. I have a list for the dealership this week, get all the software updates installed, check the wiper sensor and fix the connection to the Remote App and others. Just got the ceramic coating done yesterday and man it looks great. Guy said the paint was pretty thin but not unusual these days. Seem they are all going thinner and thinner. Anyway, I will post an update once I get everything done and get the car back.

yeah, mine suck too. on occasion, I would guess around 50% of the time they start to speed up and don't stop even after the rain has. Have to manually turn it off. Also I notice that they are really slow to react and wipe when the windshield gets wet. But the worst is at night it always drywipes, seems to happen if I drive under a street light or overpass. I gave up on them and turned the autowipe off in the menu. BTW what is that winter mode thing about, I turn it on and don't notice any difference, it supposed to park the wipers up but it doesn't seem to do a **** thing.

Must just be a poorly designed system. Never had this issue with any other RS wipers going back to my 2010 Genesis.

I had this very same problem. Dealership replaced the sensor, and the wipers have been working perfectly ever since.

I know on Porsche rain sensors, the sensor had to be recalibrated by the dealer if the windshield was changed. They work by measuring differences in refraction of an IR light from an LED that shines on the windshield at a steep angle which is then read by a sensor sitting at the opposite bounce side of the angle (picture a shallow V). When water appears on the windshield it changes the refraction index of the outer glass layer and the change in reflected IR is detected. You can see how this might be really sensitive to the finer characteristics of each piece of glass.

Extrapolating from this I assume they have to initially calibrate the sensor for this car too. Maybe yours came from the factory miscalibrated and you just need the dealer to do a recalibration?
