Does anyone with high-beam assist have an issue with the high-beams not coming back on once they turn off?

Driving with the high-beam on, oncoming traffic leads to the high-beams turning off, after things have cleared and there is no other oncoming light or street lights, the high-beams won't come back. I notice that the light beam is on the low setting and the blue indicator light on the dash, does not come back on. I have to toggle the switch a couple of times to get the high-beams back on. If I deactivate the assist, the high-beams come on manually as you would expect.

Sounds odd if you mean the car does not see any lights from facing traffic or other lights that could affect the system. And you are driving above the speed threshold where high beams come on?

The car does turn the high-beam off when another car comes at us. It must do that efficiently as I have never been flashed by the other driver that my "brights" are on. The issue is that the brights do not return once the road ahead is clear of oncoming traffic. As far as speed goes, I don't think I'm driving to slow or fast...on the one road in question we are driving 30-40PH. Maybe we are not at the 34MPH threshold long enough to engage the brights? There are no street lights on this road either, just houses. But there are long stretches of just darkness too.

One thing to keep in mind there is a minimum speed threshold which you must be above in order for the adaptive high beams to operate. I think this is in the 35 mph range. This could explain it. Otherwise, something is not quite right. Try it on a road with a higher speed limit and then you'll know for sure. Good luck.

Yes I understood that your car does switch low beams but I was asking for the case after the facing traffic is gone. Some lights other than that from cars driving the opposite direction can disable high beams but your clarification seems to explain there are none. So far all guessing seems to be towards the speed threshold.

Mine works like a charm. Only thing I've realized is that the high beams won't come back on if there is ample ambient lighting on the roadway. If there are plenty of lights on the side of the roads, it picks them up as on-coming traffic.

Mine work very well, too. It's like watching the headlights do a little dance at night. I live in NC and the roads here are dark--even within city limits. I'm always amazed when the system "sees" tail lights in front of me and brings the lights down to somewhere between high and low until they can safetly go back to highbeam.

After further experimenting, it does seem to be speed related. It appears that the car has to be going consistently over 35MPH for the high-beams to fully engage. The sensor is VERY sensitive to light. I guess for safety reasons this has to be the case.

To be honest I never found toggling the switch between low and high to that big of a pain that I wished the car would do it for me.

reflective street signs can also impact the system and cause it to think there are other headlights

i dont use it much as i feel with high beam going on off all the time the bulb will burn. its way 2sensitive but i have to admit it works like a charm

The bulb in not going on and off, it's always on. It just changing the light distribution.

thats good to know....
