Windshield wiper turns on when I start, Why?

Definitely not a "courtesy wipe" otherwise it would do it all the time. Mine did it more frequently, then I had a windshield replacement, then the sensor didn't work at all. They then performed a calibration on the sensor and now it rarely does it.

+1. Seems to be related to latest update.

This has happened on a sporadic basis since I took receipt of my R1T in September. Wiper would wipe once across the windshield, usually when I went to shift the car into Drive or Reverse. I contacted the service center about it in October 2022 and was told it was a known issue related to the sensor and would likely be fixed through a future OTA update.

It did seem to get better and much less frequent for several months, but sometime in the last month or so it has started doing it again on a more frequent (but still completely intermittent) basis.

I filed another service request with Rivian about this and my service advisor (Peng) informed me that this was considered a "courtesy wipe" and that it should happen 100% of the time when I start the truck when the wipers are in automatic mode. Peng said the only way to keep this from happening was to turn off the automatic wiper mode.

If it is supposed to happen 100% of the time when wipers are in auto mode, it is failing miserably.

Either way, I agree with the earlier posts that it risks more damage to the truck's wiper blades and windshield than providing any courtesy benefit, so I would prefer this this feature be removed.

My guess is that it has more to do with sensor functionality or sensitivity than anything. I just wish Rivian would provide a consistent response.

Yeah, I hate this 'feature'.

This isn't unique to Rivian, in my experience. My previous vehicles -- across multiple brands -- all did it, too.

We had rain here the other day but it's been dry since. Last couple times I've gotten into my Polestar with the auto-rain sense turned on I've gotten a courtesy wipe as soon as I sat down. I don't remember it happening, maybe it felt bad that my R1T has been in service so long.

Latest update is causing this again

Covered sooooo many times. This is part of the calibration routine of the rain sensor, not a function of the vehicle software.
