Hi - it’s me again! Lots of questions as a new owner and appreciate the help. I was driving in very light snow flurries tonight – the kind that is basically drizzle by the time it hits the windshield. I got an alert that the LKAS and the collision detection system were turning off, which I was a little surprised by - I had seen in the manual that it goes off in bad weather, but this was pretty normal weather. But then I was even more surprised when I tried to use the forward cameras and it said that due to a radar problem, those weren’t working either. Only the rearview cameras worked. Is this standard? Does everything stop working in the lightest snow? I had forward cameras in my Infiniti for 11 years and they never turned off.

 

It’s normal. When you stop wipe off the Acura logo in the front grill as that will get your systems working again.

 

Had it happen to me for the first time since owning the car for over a year. Now I kinda wish the radar wasn’t behind the emblem but on the windshield so you could use your wipers or windshield defog.

 

a year is better than four days, which is how long I’ve had the car. Seeing as I am on Chicago, it’s not great. Very typical weather.

 

I am not so sure you should use these automated systems in foul weather in the first place.

 

More interested in the cameras, even if the picture is compromised. Not clear why they can’t just show whatever they see?

 

Yep, happened today for me too. First time driving in any sort of snow. It was a very light snow/sleet that barely accumulated. Got the same error message. It also made a parking sensor go nuts for a brief moment as well.

 

We got our first snow storm in New England last night. I clean the snow and ice off the car. The ice is stuck to the front emblem. I got the same warnings in my dash this morning while driving. This seems like a routine whenever snow/ice accumulated around the sensor. Acura did a poor job in the design. I wish they put some kind of defroster in the emblem to melt away the snow/ice. The system is unusable until all debris’s is cleared out.

 

Great, another flaky design that you really need in bad weather. Maybe Acura should have installed a mini-wiper on the front emblem....:-)

 

Interesting that I have the same system in Canada in my 2018 TLX Elite with lots of days of light snow or sleet/snow and I have only experienced that 1x in very messy weather where the road grime accummulated on the front. Perhaps it has something to do with the shape of the vehicle front end?

 

I've had this happen with Advance RDX 2020 in the US. It snowed enough to cover the front sensors and my car was going nuts, alerting me that I was about to hit things and beeping. I chalked it up to a strange occurrence but I had only had the car a couple days at that point. It hasn't snowed much since here but I think what is becoming clear is that the front sensors of this car do not like snow. I can totally live with ACC and LKAS not working in snowy weather, that's perfectly understandable. In fact, you shouldn't use cruise at all in snowy weather. I am more concerned however with the annoyance of having the car freak out like I'm about to hit something because the sensor is blocked, rather than realizing the sensor is blocked.

On that note, I think my ultimate fear is if the car tried to brake itself to avoid a collision it thought was imminent due to the sensor being blocked. Is that an irrational fear, or has that actually happened to anyone? If the car were to do that on an interstate or at the wrong time on slick road surfaces the result could be an accident you'd be at fault for.

 

Totally agree with this. I wasn't in need of either system, and prefer them not to work if they can't work safely, of course. But the crazy beeping seems like a very weird reaction for a supposedly advanced car to have to a bit of snow flurries? And I still don't understand why I can't use the camera for parking purposes -- this really irritates me, because that camera is the reason I took the very expensive Advance package.

 

It's rational. I'd disable them while it was snowing if I lived in a place where it was snowing.
