    During a week of rain here my front sensor was not working and I was getting the errors. Tapping on the sensor with my fingertips, pretty hard, fixed it every time. Wiping it did not.

    I suspect there is moisture somewhere inside it and tapping it causes the water to drip down.

    This Winter will be the first for many Prime owners that got a cheap 2017 this year. Interesting to see how these sensors cope with the inevitable ice!

    Oops. Sorry for the misplaced post. The two in the middle of the vehicle are not visible on the vertical surface. Put your hand just underneath the bottom edge of the car in the area below the front door on each side and you can feel the indentation of each one. It would be too difficult to take a pic. I hope this helps.

    Hi Everyone. New member. I have this issue on my 2018 Prime and have been working with the regional Toyota tech. So far the car has been in 3 times for attempted repairs. The first time was the dealer mechanics, the second was directed by the regional tech and they replaced the front 2 sensors. The last was spent all day while the regional Toyota tech tried to replicate the problem with a garden hose. They have asked me to make videos detailing the issue. So far I've made 9 with maybe the most interesting one being this one where I show the corner sensors still working while the front sensors are failed. Might want to listen with the volume off since between disappointment in a new car having such a nagging problem and no caffeine I cant seem to differentiate between corner and side sensor. This was also before I discovered the alarm goes into "clean the sensors" mode once you reach 2-3 MPH. We've had a rainy week and the car has turned into an alert factory.

    I cant post hotlinks yet so I'll try to post the straight url below.

    Holy that's annoying. How did Toyota think that people are going react with that thing going off on the drive to the dealership?

    You can turn ICS off via the menu settings. I can't remember if it'll stay off the next time you start the car.

    This issue happened to me today. It was raining a lot today and I did drive through some heavy stuff. And then the sensor alert thing happened and it kept saying to clean them. So I did, several times, to no avail. It's supposed to rain hard here for at least another day or two so I'm just going to put up with the annoyance of it (it actually does come and go) until it can dry out for a few days. I haven't had a car with issues since 1993 and never with any of my Prii. I'm so hoping this is going to "fix" itself.

    I just watched your video - this is EXACTLY what mine is doing.
