Smart Cruise/Parking Assist/Cross Traffic/BSM sensors don't like heavy rain.

[Mr. Incredible]

yesterday and today it was pouring in SoCal, and heavy traffic and trucks with major water spray, and all the "Smart" systems on the G80 went nuts.

Got all of these alerts in a heavy down pour yesterday on my 30 my commute to work:

SCC - started getting SCC Disengaged, Radar Blocked graduated to SCC disabled. Radar Error, Please Service
Park Sensors - Park Sensors Failed, Please Service
BSM - Blind Spot Monitor Error - Please Service

On the way home when I started out it was misting and everything was fine, the closer I got to my home the heavier it got so visibility was near zero with all the Semi-Truck water spray and all the alerts came back.

When I left this morning it wasn't raining, part way to work and the skies opened and all the alerts came back.

definitely tied to the heavy down pouring rain..

be safe out there.

Yes, normal behavior. I've run into it a few times in heavy rain or snow. This is not military grade radar and it can be blocked.

first car I have owned with SCC, but not with parking sensors and BSM and no other model ever did this in rain or snow. Of course no other model I've owned has had the Park Sensors go berserk around specific other makes, mine go into a fit anytime I am around a Ford or a BMW.

Funny you say that, my parking sensors interact with every car around me. I can look left/right/back etc and everybody else with park assist is doing the same If I get annoyed I just disable them.

But the tradeoff is my parking sensors are far more sensitive than any other vehicle I've driven. Quite a few of them don't even beep unless it's something more solid than a bush.

Oh yeah the front ones in the grille trigger on parking curbs. Which is nice, The ones that were in my Lexus wouldn’t tigger for anything less than a solid wall.

I came to Genesis from an RC-F, that poor car was like a deaf bat and couldn't see concrete walls unless they were 6 inches away.

I came from a 2015 RCF as well

Same here!

Not normal behavior. I agree with you mr incredible. The genesis must use an inferior radar sensor in the parking and Scc system because I’ve had Honda cars from 2013 with this tech and a 2014 Jeep with this technology and the sensors always worked and never went haywire. Only time would be if I was driving in slush being kicked up. Too bad a luxury brand decided against a higher quality sensor.

No, Honda and Jeep just used inferior sensors that can't tell when they're being occluded or not. They wouldn't work either, but you wouldn't know it.

But they did work.

But they don't work the same way or with remotely the same precision. Neither Honda nor Jeep have offered a radar system capable of operating below 25MPH, the technical requirements in regards to multi-pole operation and noise filtration needed make it too expensive. Being able to arbitrarily say "anything going much faster or slower than me can be ignored" is a big difference compared to "I need to be able to determine any speed greater than 0 relative to me at whatever speed I'm going, plus I need to be able to know when my target is no longer moving vs other moving targets".

Being able to operate in stop and go traffic demands that any excessive interference be treated as a fault and disable any expectation that the system will continue to function.

 

[Light2000]

Correct, they worked better! Haha. The adaptive cruise sensors don’t get confused in rain and the parking sensors don’t get confused by random clutter it might detect. My 2014 Jeep could bring the vehicle to a stop as well, smoothly,so it was indeed operating below 25mph.
