    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.

    My 2017 Prime Advanced is demonstrating the same problems. The Clean Parking Sensor Warning goes off, the the "ICS Unavailable" warning comes on. Beeps constantly when driving, sometimes - extremely distracting! All this started when the heavy rains came last week. I have cleaned the sensors many times, they're almost immaculate.

    Exterior sensors should work in the rain, no?

    It seems to be pretty random for me. I have had it go off during very light or misting type rain and yet not go off in heavy downpours. I just ignore the beeping and wait for it to disappear on its own. I wiped all the sensors when I first got the car, but too tired to keep doing it. Lol

    I had the same issue on two different occasions when I first got the car. I have not had that message in a while now.

    Try tapping on the sensor with your fingertips, firmly. I had luck with this. The water inside "drips" down from the agitation.

    Thank you to everyone who has gone to the dealer for this and persisted on a fix. It will help get a recall or TSB created for all users with this issue.

    With all the rains in California, the ICS beep warnings and also he "Clean Parking Sensor" alerts are driving me crazy. I have cleaned the sensors but the alerts still occur randomly.
