Inermittent warnings

[jchar27]

Ok, I've searched the forum for half an hour, now I have to actually do some work, so I thought I'd throw this out there. I saw a thread about various warnings the other day, but can't find it again. I'm having intermittent warnings with the parking assist, where alarms are going off for no reason. This mostly happens in the rain. Seems to me, rain shouldn't effect this system. Anyway, I have already been to my dealer for the AEB warning problem, which happened in the snow. This was fixed by wiping the snow off the black square sensor. This to me is a design flaw, considering they built an AWD system, with SNOW mode, yet actual snow virtually makes a very significant safety feature useless.

Anyway, back to my original thought. Has anyone had faulty sensors replaced, or a system reflash? Did it help with these intermittent and false warnings? Or am I doomed that every time I drive this car in inclement weather I should expect to have to disable safety systems or be annoyed by dings?

AEB problem? One could make the same argument about snow blocking the windshield. Just wipe it off and go.

Yes true, but I have windshield wipers for the windows. I have had several times in my life where I'm forced to be out driving in a snow storm, several long trip. I can't imagine having to pull over in a snow storm every few miles to wipe off the sensor.

Don't get my concern wrong, I love the car, just think this amazing safety feature falls a bit short.

Not to burst your bubble but yes you will get multiple AEB warnings because snoq/slush/salt/crap is blocking the sensor. Does not matter if you have a Rolls Royce or a Lada it will not function correctly if blocked. No different on the Gen 1 with smart cruise which will also freak out on the Gen 2 if dirty. It will actually cancel the cruise function on the Gen 1 so no more cruise period. At least on the Gen 2 you can go to manual cruise and continue on your way. Same goes for parking sensors, they actually need to "see", if they can't, how do you expect them to work. None of these are oversight or faults or poor engineering. With todays technology this is as good as it gets.

I have had random park assist warnings. But I am starting to see a pattern. Many of the times it happens at a particular intersection when relatively no one is around.

But across the corner from me is a microwave tower, and a TV weather radar. ALL things like that can put out high energy and mess with all kinds of things, including sonar type distance sensors.

Good explanation

Imagine problems when we get Google cars LOL

A frog-strangler rain will give the same intermittent warnings, but require no recovery action. Really surprised me the first time it happened.

One intersection near home gives regular parking sensor warnings because the highway is much higher than the side road approach. Same thing happened on my 2009.
