Why is the front sensor so low Hyundai engineers?

[brooklynite]

Last year we were driving in Utah and it started snowing, and within a few minutes alarms went off that all safety system is shut down because sensors aren't working. Think it's getting dark and I have a small child in the car and barely any cellphone reception between Parowan and Brian Head in Utah. So I pull over in 6F cold and got out of the car and see the front low sensor was covered with 2" of brown and dirty road slush from the road and cars and it was already frozen and I couldn't clean it. Even if I did clean it, I could possibly damage the sensor, and furthermore in 2 minutes it would be be covered again because it's positioned in the worse spot up in the low point of the front.

Then I'm looking at 9 square feet of gigantic front grill that is all clean from any snow and thinking why the hk they didn't put the sensor higher.

Not a question, just a friendly rant from an engineer to another at Hyundai design center. Hopefully you see this and think about it.

Enjoy the beautiful photo of the car in snow. It was magical.

As you can see in your picture, every forward-facing part of the front of the car is covered in snow. So it wouldn’t matter where on the front the radar was placed… it’d have the same issue. The only places where snow wasn’t built up are the spots where there’s an open grille.

This isn’t unique to Hyundai. Radar doesn’t like to be blocked, and vertical plates on the front of cars will catch snow, especially when it’s wet and sticky. These systems are supplemental, not critical.

The Genesis sedan cruise control/collision radars are 2-2.5 feet off the ground and have the same issue because of it being a large, flat, forward-facing surface. It can't really be avoided. The OTHER sensors (parking) you want to keep low to make sure you don't hit things like curbs, fire hydrants, decorative rocks/planters, etc...
