Just bought a new 2017 GLE with Active LED and Adaptive High Beam Assist. Discovered a safety issue where the driver-side headlight will go into high beam when it should be in low beam, blinding oncoming traffic and cars in front. Because the lights are so bright, it's a huge safety concern. Note that it's not known to the driver, only those cars in front or oncoming that's it's happening, which may be why more complaints haven't been filed. Mercedes Benz, Richmond VA tested other new GLE's with similar lighting on their lot and ALL are having the same issue. They think it's an issue and tried to repair it. The repairs they tried did not work. A complaint was filed with Mercedes Benz USA, who recognized it as the first time they heard of this issue. It was elevated to the higher ups and engineering team. Upon further review they came back and said this was normal operation of the adaptive system and that they were not going to do anything further. I find this to be unacceptable as it's a safety issue for other drivers. Test your GLE, have someone ride in front of it, and let me know if you're experiencing this issue as well. This is of huge concern to me and should be to any GLE driver. If you're experiencing this issue, please file a complaint with MB USA. The more complaints they receive with hopefully make them resolve this issue. I'll post a video of the issue soon.

I haven't noticed an issue with mine. The high beams turn on and off as they sense oncoming traffic or other ambient light just like they should.

Mine works fine as well.

No issue with mine.

Frankly - in Auto - over 60mph - if Auto has you in high beams you will see the indicator in the cluster - where you say "as drive you are unaware".. nice headlight system - like really/really/really nice actually..

Just posted the video for reference. See original post.

Use my GLE Lights in Auto mode exclusively. No issues. High beams go on and off automatically to oncoming headlights as well as tail lights.

Yeap, mine work fine too. The only time I've noticed that they even are slow to respond is when I'm going down a hill and another car coming at me is going down the hill and we meet at the bottom at the same time.

You can't tell it's happening driving the car. It's only noticeable if your in a car in front or oncoming. It's a safety issue for others.

i can DEFINITELY tell when the high beams fire-up. i have not looked at your video because it will not open without a download, and that's not happening.

is there a possibility that the curve following mechanism is not resetting? also, it does take a minute for the reset to occur. on start up at night, you should be able to see the beams move side to side, up and down and reset to center.

good luck, ron

Wouldn't some of these other drivers "bright light" us? I don't think I've ever even had that happen. (Not trying to sound like a smart a$$)

Yes, it's happened plenty of times. I brushed it off as getting "bright lighted" because the LEDs in general are so bright.

To further my argument, here's a quote straight from Mercedes of Richmond, Va invoice "PLACED ADDITIONAL DRIVER AND VEHICLE IN FRONT OF CUST VEHICLE DURING TEST DRIVES AND FOUND DRIVER HEADLIGHT INTERMITTENTLY FLASHING/ACTIVATING HIGHBEAM (DETERMINED ISSUE VERY BLINDING TO DRIVER IN FRONT AT TIMES)."

And, more from the invoice showing the same issue when they tested two other 2017 GLE's in stock. "RETURNED TO SHOP AND LOCATED ANOTHER VEHICLE IN STOCK ON LOT WITH SAME LIGHTING PACKAGE. PERFORMED TEST DRIVE WITH ADDITIONAL VEHICLE/DRIVER (ADDITIONAL VEHICLE IN FRONT, AND 'IN STOCK' VEHICLE BEHIND) DETERMINED ADDITIONAL 'IN STOCK VEHICLE HEADLIGHTS OPERATING SAME AS CUSTOMER VEHICLE (DRIVER SIDE HEADLIGHT WILL INTERMITTENTLY SHINE BRIGHTER THAN NORMAL). RETURNED TO SHOP AND FOUND A THIRD VEHICLE WITH SAME LIGHTING PACKAGE, ONCE AGAIN PERFORMED TEST DRIVE WITH ADDITIONAL VEHICLE IN FRONT, AND THIRD 'IN STOCK' VEHICLE BEHIND) DETERMINED THIRD 'IN STOCK VEHICLE' HEADLIGHTS OPERATING SAME AS CUSTOMER VEHICLE (DRIVER SIDE HEADLIGHT WILL INTERMITTENTLY SHINE BRIGHTER THAN NORMAL)."

The dealer tried to fix the problem by 1) performing a multifunction camera control unit software update ... didn't help 2) swapped driver side headlight control unit ... didn't help 3) swapped driver headlight assembly ... didn't help.

If MB USA thinks it's normal operation of the headlight 1) why is it only happening on the driver side 2) why would the dealer think it's an issue and try to fix it?

Saw the video of the OP. Video seems legit. I have 2016 GLE but I don't think I have problem. Not sure how can I check my car except asking somebody to drive in front of my car and looking back.

On the other hand, I guess the 2 headlights are supposed to go into high beam independently of each other at certain times.

for example, if you are driving behind a car, ur left beam is supposed to be higher than right to illuminate the opposite incoming lane.while trying to avoid glare in rear view of the car in front of ur car.

similary, if there is no car in front of u , and there is a car oncoming from opposite side, your left beam will be lower than right to keep your lane illuminated while decreasing the glare for the oncoming driver

sounds like a defect. technology is a b-itch. remember that they didn't recall just 1 Note 7 (or, come to think of it -- Airbag!). hope they get this working for you. good luck, ron
