Estima radar sensor error

Alright, I'm pulling my hair out here. My 2018 Toyota Estima, gasoline engine, is showing a radar sensor error. I'm seeing the error message in the speedometer, there's an error stored in the memory, and now several driver assistance systems are failing, plus a warning light is constantly on. Mileage is at 57485 km. Could a dirty sensor REALLY cause all this chaos?

Sounds frustrating! I had a similar experience with my 2019 Renault Megane. Same error messages and the adaptive cruise control went bonkers. Is it like a chain reaction in your car too?

A chain reaction is a good way to put it! So the radar was the cause for you too? What did you have to do to fix it?

Yeah, it was the radar sensor. I was hoping it was something simple, but it ended up needing a proper look. I'd suggest getting yours checked out at a shop. If a simple Megane like mine has this issue then the Estima probably suffers from it as well.

Thanks, that's the plan. Turns out the radar sensor was just filthy! Cleaned it up and everything's back to normal. Cost me 45€, a bargain! Appreciate the insight.
