Interesting, expect others who have the same message during that type of driving weather conditions will be thankful. Could have been still iced up for a day or so before it cleared as the weather improved.

 

I have seen many people receiving this message because of bad weather, but I could not find any case in which the message remained there for more than 2 days.

Weather isnt the only factor.

Absent your vehicle details (helps everyone if people kindly completed their profile with vehicle details) , a damaged radar, failing battery, failed radar component and general electrical gremlins can all be catalysts for the radar throwing up an error - and in any of those examples, errors can stay forever if not tended to.

Your experience is neither unique, nor a barometer for others' experience either I'm afraid.

 

More then likely you simply had water behind the cover or on the front of the radar itself. The plastic piece in the grill is not the radar but a cover. The radar looks like the attached photo. The cover is easily removable, which is why owners find them missing.

 

Thank you for the replies. My car is a 2022 Hybrid EX-L. Is it possible to clean ( and dry) the sensor directly in those cases?

 

I would assume so. I would try it next time it happens.

 

On the 2022 cover there tabs located on two top corners. Reach in thru the grill with your fingers and gently press down and pull forward with your fingers to release the tabs from the grill.
On the earlier 5th gens the tabs are on the sides of the cover and you push in side ways instead of pushing down on the tabs.

 

Good to know. Thank you very much!

 

As Traylaw noted above, since it self-cured, I bet some moisture managed to find it's way between the plastic bug plate and the actual radar array antenna behind it. If that did happen and it did freeze in there, it would confuse the radar and take it off line until it dried out.

Keep in mind, HondaSensing is a fair weather safety assist system, NOT an all weather safety assist system. It often continues to work in bad weather, but not always.. and is prone to the radar or camera going off line in snow induced visual or signal interference. Set personal expectations accordingly.

 

Got it. Thank you.

I was just intrigued by the fact that my problem lasted for a long time... the cases I have found here were "self-fixed" in less than a day.
