Cruise control radar

[Ernie3647]

I agree with you, but to give one example, I was on a 900km trip recently, all highway and drove through a localized snow shower, bad enough to cover the cruise radar sensors with slush and dirt. During the snow I obviously was not using cruise control, but soon after we were back to clear dry pavement. The temperature was cool enough that the snow covering the sensors did not melt very quckly and in combination with the dirt it was enough to disable the cruise control. When I stopped a while later I cleaned the sensors and all was good again, but the inconvenience of losing cruise control completely, just because the 'adaptive' sensors were blocked is a PITA and in my opinion totally uneccessary. It should just default to 'normal' cruise control.

I posted a fairly similar remark when I first got my 2011. Same situation while driving during snowy weather the front sensors iced up and rendered the smart cruise inoperable even though the snow stopped and the road was clear. Boy did I get a lot of negative responses most saying that I shouldn’t be driving if conditions are such as to disable the cruise system. When I responded saying that my “2007” Infiniti G allows use of either in case the smart cruise is inoperable things really got ugly. So there you have it. I am one of only a few who would like to see both systems offered for the mentioned reasons.

I hear you.
Crazy thing is that although I don't practice or condone the use of cruise control in slippery conditions, the Genesis is one car where it can be done relatively safely (note relatively). I had an instance a couple of winters ago where I was driving on open country roads with the cruise control engaged on a cold but dry morning. I came to a stretch of road that was shaded by some tall trees and the instant the rear wheels were in the shade I got a twitch from the rear end (mine and the cars ) - Black Ice! Before I'd even had time to adjust the steering wheel to correct the wiggle, the Genesis had disengageed cruise, reduced throttle and applied the ESC system - I'm talking blink of the eye fast here - and the car continued in a straight line. To say I was impressed is an understatement.

We need an electrical engineer. The radar evidently must be allowed to work for the CC to work. That means some kind of signal being sent back to the CC computer. We need a little black box that can be spliced in to provide that signal when a switch is turned on.

There have been a number of enterprising types that have provided work-arounds (for a price) to deal with some Corvette eccentricities. One defeats the forced shift from 1st to 4th under light loads and another defeats the troublesome steering lock. I suppose the market isn't big enough for a Genesis, however.

I guess one could just remount the radar sending unit so it is aimed upward---------giving you a normal CC, but no way of easily switching back and forth.

Why would you want to turn it off? I set mine at the furthest distance and enjoy the adapt control. When it starts to work I just move into the passing lane and never need to worry about the gas pedal.

My girlfriend hit a rabbit and now the radar is out of whack. I was hoping there was a way to disable smart cruise and use conventional cruise.

OK, Here is how to turn OFF SCC and have plain CC.
This is on my 2018 G80 3.8 RWD BASE. It may work for you also. Give it a try.
1. Turn on the ign.
2. Turn on the cruise system.
3. Press and hold the distant button for 3 or more seconds.
4. A message will pop up saying what mode it is in.

It will be Smart cruise on or Cruise on. (or something like that.)
The only problem I see with this is there is no indication what mode it is in until you switch modes.

This also works while driving.
Thats all I know about it sofar.

...The only problem I see with this is there is no indication what mode it is in until you switch modes....

For me, there are definitely different indications in the instrument cluster when it is in normal cruise instead of smart cruise.

What car do you have?

What car do you have?

Yeah, that's a catch for sure. The closest that I have is a 2015 Kia Cadenza. I was/am assuming that the displays would be similar. I've also driven a 2018 Camry (rental), and setting its cruise control to manual is the same. It also had a different display when engaged.

Old thread but from 2015 on,, Hyundai cruise control can disable the 'radar" thing. I drive all different cars, working for Enterprise, and ALL the cars have the ability to defeat the "adaptive" radar thing. Too bad the responders can't just answer the question, which is what the originator wanted, rather than give their opinion on how much they "love" the radar function, which is NOT what the originator is looking for. Good Lord!

I can't afford a newer Genesis so I would LOVE for someone to come up with a "fix" for this damned adaptive cruise control. Does it actually use radio/radar energy or some hi-pit
ch sound waves? Anyone know?

What is it that you actually need fixed?
Adaptive cruise uses the front radar sensor and the front lane assist camera. Mine works just fine.
The sonic sensors are parking sensors only. Mine works well, considering the limits of this technology.

No, he's saying that Hyundai lawyers are smarter than Infiniti lawyers.

Most likely they are all saying the same things. The lawyers analyze the issue and likely noted the risk. It was then up to the client, the car company executives, to determine if they want to run the risk. Where there likely was some divergence would be on the amount of risk (given Infiniti's sales, probably not much for Infiniti).

According to John Krafcik, CEO of HMA, lawyers have said it would create a legal liability issue if they allowed it to be turned off, because someone may get confused and forget it was off, and be driving while thinking it was on and depending on the car to slow down on its own.

Probably similar to the idea of driving with the trunki/hatch open. some cars seem to allow it and some, like my GV60, don't. A golfing buddy of mine got a Lucid Air and its hatch needs to be closed as well.
