What was wrong with the windshield?

 

See my other thread for windshield information. http://www.crvownersclub.com/forums...official-specs-features-etc-gen-5/126666-2017-crv-touring-windshield-crack.html

 

I had that occur on my '15 last month. I was driving on I-80 in freezing rain outside Des Moines. The dash lit up with warnings and it cancelled the adaptive cruise. The radar was covered in ice at least 1/8 thick. I was surprised it was working at all. It was a good warning sign of what lay ahead on the interstate...40 miles of accidents and driving at 20-30 mph.

Yours was probably a leaf or trash on the radar for a moment which got blown off.

 

Yup, same happened in wet snow/slushy weather a few months ago in my '15 Touring CRV. I was highway driving and it occurred all of a sudden. About 30 minutes later the system went back to normal. Sounds like a correctly functioning system that is aware of when conditions are not conducive to radar.

Happened to me today twice due to very wet snow. Coming back home from getting the windows tinted and 5 min from the tint place it gave these warnings. I pulled over and saw the ice and wiped it off. Lasted probably 5 more min and was iced over again. I didnt stop again till I was home. A small heater that could be turned on from a switch inside to warm the radar antennae would be a nice addition. That way you could choose to only run the heater when there is winter precipitation.

 

I'll just weigh in that I've had this too - in just light rain and mildly foggy conditions on the freeway. When it turns off, it's quite the display with all those goodies turned off! It corrected itself within 3 miles (I was impressed that it didn't require an ignition cycle to clear!), and both sensor spots were clear when I looked at home, so I chalked it up to conditions.

When we first got our '15 Touring, the ACC would suddenly drop and not re-enable unless you stopped and turned the engine off and then it would be fine for some random number of days. Complained about it at the next oil change - they applied a firmware update and it never happened again. So, I'm confident if there's an issue, Honda will fix in time. But so far so good.

I think I would firmly classify "Adaptive Cruise Control Won't Work In Horrible Conditions (where it's blissfully unaware of how little traction is available)" as a Good Problem to Have. It's simply not able to react adequately to, say, a car beginning to spin in an adjacent lane. And if there's a patch of black ice under the tires, it doesn't know to use idle to slow down and use the brakes as little as possible.

Yeah, it'd be nice if the CMBS still worked, but in such conditions, it'd do you little good anyway.

 

Happened to me today when the weather was slushy- warning popped saying collision braking and lane keep disabled- I wonder if this is same with other Manufacturers- because sensor location on crv gets dirty easily

 

I believe putting the sensor in the bumper is pretty common since you don't lose much.

 

If sensors block so easily- than very disappointed

 

Other than behind the rearview mirror, wear specifically are the sensors on an EX??

 

Sensors are located in the front grill just underneath Honda logo

 

On my 2017 CR-V two days ago while I was driving through snow and freezing rain ,and using the adaptive cruise control ,it worked fine until the sensor got blocked .When I wipe it off it works again .I think they should've put it in a place that doesn't get blocked so easy

 

Let me get this straight, you were using adaptive cruise control in freezing rain AND slush? I'm pretty sure the manual is plastered with warnings telling you precisely to NOT do that, lest you kill somebody with it.

If conditions are so poor that the sensor is getting clogged with slush and freezing rain, would the features even work correctly if the sensor still worked? The car has no idea that you'll have greatly reduced traction and need following and braking distance vastly greater than normal. ACC in such conditions is sheer lunacy, CMBS won't actually work that well, and since slush is going to cover lane markings, LKAS and Road Departure aren't going to work either.

Also, by necessity, it has to go on the front of the car. The upper part of the windshield is too crowded. That leaves somewhere on the grille. Really, it's better off than many automakers, which embed it in the lower grill; I expect that gets clogged even MORE often.

It mentions it in the manual at least 20 times that it does not work in Rain, Ice and Snow. :wall:

 

Tonight once again the sonar sensor on my 2017 CR-V Touring got blocked again. It is definitely a magnet for any type of snow or freezing rain. It wasn't even any serious bad weather. They should have a heater or a wiper blade that could be use to clean the little ice that so easily it collects.

 

Had it happen to me yesterday- little bit of slush from other cars blocked the sensors. Cleaned it during a break- happened again in about half hour. Too bad as weather was very foggy- I could have used adaptive cruise.

 

pull over and clean your window camera and radar sensor area.

 

I've had this happen three times since getting the car in December. First was in fog and heavy drizzle on the freeway. It restored itself within a few minutes - nothing on the cover. Second time - not sure, wife was driving it. Third time was today. Drove through a heavy rain and road spray for 8 miles or so on the freeway. No LKAS (invisible lane markings) but everything else was fine. Came out of the rain and after 5 miles of driving in nothing but clear air - the radar shuts off. After about 3 or so miles, returns to normal. Nothing on the cover, clean windshield.

Early in our 2015's life, the ACC would drop out for no particular reason. It would not reengage unless the car was stopped, turned off and restarted. I griped it to the dealer, and a firmware update fixed it. So, I will be griping the 2017's issue at the next dealer visit and hope that something fixes it down the line.

 

I had the same issue driving in a moderate to dense fog on highway. It got corrected within few miles. I wished if there is a way to get the regular cruise control work but I didn't know then. After coming back home, looking in the manual, I see there is an option. From the manual (page 481 of online manual)
"To Switch ACC with LSF to Cruise Control
Press and hold the (interval) button for one second. Cruise Mode Selected appears on the driver information interface for two seconds, and then the mode switches to
Cruise. To switch back to ACC with LSF, press and hold the button again for one second."
I tried to test this yesterday, but didn't work. Did any of you tried this and working for you ? What could I be doing wrong ?

 

You have to hold it for more than one second. It will beep when it switches to regular cruise control. It does seem to be a little tricky to figure it out. Seems like sometimes you have to hit cancel, then hit the button and hold it until it beeps. Keep playing around - it will work.

 

It got blocked for me in the rain at 32F today. Not exactly the best engineered location.

 

Where else would you put it? It's in pretty much the same place every car with a radar puts it.

 

On the Civic, the radar sensor is located down near the ground on the left side of the vehicle next to the fog light. I've never had it get blocked on the Civic, but it has on the CR-V.

 

Thank you for posting about this. I got this same warning last weekend after approximately 20 minutes of highway driving. Like you experienced, the indicator disappeared shortly thereafter. In my case, however, I do not feel that the lane departure function has worked since this occurrence. I have purposely veered into adjacent lanes and nothing happens. I called the dealer this morning and they had never heard of such a thing. Of course they then told me that I would need to leave my car for an entire day for them to try to diagnose it with help from American Honda Corp. My first thought was that something was temporarily blocking the sensor. Could someone please tell me where this sensor is?

 

The lane departure and lane keep assist functions are based off a camera that looks forward from the upper part of the windshield, near your rear view mirror. Look at the upper center of your windshield from outside the car, and you'll see the camera and the little V-shaped field of view that it has. If it cannot detect the lane markings, it will not work.

 

Lane departure also auto disables in rain if wipers are on ( as per a magazine review)

 

Interesting, when I had a my first heavy snow, my radar disabled itself very quickly. I mentioned it to the salesman and he commented that it was probably good, since being in Colorado, we do get a lot of snow sometimes and you don't want to have anyone-you or the SUV slamming on the brakes hard in glazed ice/snow without some thought.

My first thought, yeah, a typical defect now being a feature. LOl But he may have a point.

 

I had a similar issue with the errors randomly appearing, even in good weather. Dealer performed this procedure.
