RX Radar Sensor Malfunction

My 2022 Lexus RX hybrid with 131565 km is having radar sensor issues. Error message in the speedometer, error memory confirms the sensor malfunction. This is causing failures of various systems, and a persistent warning light. Could this be a dirty sensor impacting the driving assistance systems? Anyone seen this?

I've had a comparable experience with my RX. Same symptoms, electronic issue for sure. Have you checked the sensor itself for any obvious obstructions or damage?

When you had the issue, was it consistently failing, or intermittent? Did you try any troubleshooting before going to a professional?

It was consistent once it started. Given the interconnected nature of the systems, and the potential for radar calibration being necessary, I'd strongly suggest a workshop visit. A diagnostic check will likely pinpoint the problem, and it's best to ensure all systems are properly aligned and functioning. It ended up costing me around 45€.

I appreciate the advice! I will schedule an appointment with the workshop to have the radar sensor inspected. Thanks for sharing your experience.
