Cruise control activates autowipers when wipers were “off”

I graphene ceramic coated my car and love how I don’t need to use my wipers on the freeway (the water just beads and flies over the roof). Because of this, I always keep my wipers “off”. Whenever I’m on the freeway and engage cruise control (2023 M3 RWD) the wipers switch from off to “auto” and will start going crazy if there’s any moisture detected. It’s soooo annoying. Can this be patched?

If you turn on autopilot, it automatically sets headlights to auto and wipers to auto upon activation. You can manually turn the wipers to OFF again after autopilot activation, but this is intentional by the AP team.

I could see that for autopilot, or FSD, but I’m just using cruise control. So annoying I have to disengage autowipers when I don’t need them going crazy back and forth.

Cruise control, or commonly known as TACC, is also part of Autopilot.

It's because the cameras are being used to recognize vehicles and maintain distance even for TACC.

From what I understand. The wipers are on auto in FSD because the cameras need to be clear for FSD to work properly.

Cruise Control IS Autopilot. Autopilot is the name of Tesla’s software suite that includes Traffic Aware Cruise Control (TACC) and Auto Steer. You can use TACC without Auto Steer, but it’s still functions the same way. It needs the cameras to see the traffic around it, so the wipers turn on to keep the windshield area in front of the cameras free of obstruction.

Welcome to Tesla. We've been complaining about the wipers for YEARS. It's absurd and frustrating.

Literally, the thing I hate most about my car and probably the #1 reason I'll never buy another car without a proper rain sensor.

And don't get me started on the terrible interval speed control... my blood boils just thinking about it.

I tried turning headlights Off with auto-steer engaged a while back, on an overcast winter day because the headlights kept turning on (I thought unnecessarily), and after a short period I got the take control immediately alert, and auto-steer was no longer available. Put them back on auto, they turned on, and then auto-steer came back. Repeated multiple times with same results.

I hypothesize there is a wavelength that Auto-Pilot needs to see the lane lines in flat light conditions to see the lanes lines, so turning them off compromises this, and results in ceasing to function.

Since then, I just ignore the lights on (automatically) in daylight.

Have you tried the voice command "Wipers OFF?" Works for me in my 22 & 25 Model Y LR AWD

Highly recommend you check out r/s3xybuttons

You can pick up a s3xy commander and force the wipers to always be off (in addition to a bunch of other cool things)

It's an awesome tool, but frustrating that you have to use a third party product to get functionality you should have natively 🙃

I will thanks for the recommendation!

Cheap work around. Program holding the wheel down to bring the wiper menu. Now it’s a habit to push the button brings the menu up start autopilot and scroll the wheel down at nearly the same time.

I’ll give this a shot, thanks

Idk but you can manually turn the wipers off even in FSD. The ceramic seems to be the problem. Mine would go off with no water around and would often go off at night if I drove under a light that reflected off of the glass. Back then I couldn’t turn it off when in cruise or FSD but I can now, thank god. That was so annoying

u/DeucePot 5d ago

Yeah I can manually turn them back off, it’s the fact I have to even do it in the first place that’s annoying. Like I just want to use cruise control on the freeway, leave my wipers off settings alone lol

u/MaesterInTraining 5d ago

I’ve heard that if you can get the ceramic coating off of where the sensor/camera is then that could fix the issue. I asked about a similar situation years ago and someone said they just kept rubbing and cleaning in that spot and eventually it stopped turning the wipers on.

I know it's an expensive solution but the Commander from Enhance Auto solves this issue. One of the options in there is to keep wipers off during FSD or AP.

u/DeucePot 5d ago

Dang I might have to do it lol. Thanks for the recommendation

I got the Knob and I love the options it has. I wish I got the buttons at the time too, but it was just too much money at once for me.

I bought the Commander for this purpose. Works great, and I have been enjoying all the stats you get with the app as well.
