Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering lighting on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The auto high-beam headlight system is the dominant complaint across these narratives. Owners describe a system that operates erratically and unpredictably: it fails to dim when oncoming traffic appears, stays on when it should switch to low beam, and dims or flickers inappropriately when no vehicles are around. The system reacts to road sign reflections and roadside markers, triggering unwanted dimming. When the system does activate, it often disengages quickly, creating distraction for the driver. Multiple owners report that dealerships have no service bulletins for the auto high-beam function and have stated they cannot repair it. One owner was told to simply deactivate the feature. A software update did not resolve the issue in at least one case. Honda declined to address the complaint in another instance.
A separate issue involves the rear-view camera: one owner reports it does not work due to a failed tailgate wire harness (recall 24V-321). Despite two recall notices, the dealership has canceled repair appointments twice, citing lack of parts availability. Honda has known about this defect since 2017–2019 model years.
One owner also reports LED headlights accumulating snow and ice during winter driving, requiring manual roadside cleaning to maintain proper visibility.

Failure modes owners describe
Auto High-Beam System Malfunction
The automatic high-beam headlight system fails to operate as designed. It frequently fails to dim when oncoming vehicles approach, stays on when it should turn off, dims when no traffic is present, and flickers or switches erratically. The system also reacts to road sign reflections, causing false dimming. Owners report the dealership has no fixes available and Honda has declined to provide a resolution.
When: Recurring since new; occurs during highway driving and at night
Symptoms owners cite: High beams fail to dim when oncoming vehicles approach; High beams stay on when encountering oncoming traffic; High beams dim inappropriately when no vehicles are present; Erratic on/off flickering at night unrelated to traffic conditions; System reacts to road sign reflections and roadside markers; Delayed dimming when oncoming vehicles are detected; Occasional unwanted activation or flashing that dazzles other drivers; System disengage quickly after brief activation, creating distraction
Repairs/costs cited: Dealership has stated no service bulletins exist for the system and no repairs are available. Honda suggested deactivation as an alternative. One owner noted a software update did not resolve the issue.
Recalls/TSBs owners mention: Honda declined to address the issue in at least one case. No recalls or TSBs mentioned for the auto high-beam function itself.
Rear View Camera Tailgate Wire Harness Failure
Rear view camera does not function due to a failed tailgate wire harness. Honda issued recall 24V-321 for this defect on 2017–2019 models, and the same issue has carried forward to 2020 models. Owner has received two recall notices but dealership has twice failed to repair the vehicle, citing lack of parts availability.
When: Multiple months without repair; initially recognized for 2017–2019 model years
Symptoms owners cite: Rear view camera does not work; Camera inoperable despite known defect
Repairs/costs cited: Parts were unavailable at dealership at time of scheduled repair. Appointment was canceled with promise of parts availability in late fall.
Recalls/TSBs owners mention: Recall 24V-321 issued; however, Honda has not timely supplied parts to dealerships to complete repairs.
LED Headlight Snow and Ice Buildup
LED headlights accumulate snow and ice during winter driving, reducing visibility and requiring manual cleaning by the driver at roadside stops to avoid dazzling oncoming traffic.
When: Winter weather driving conditions
Symptoms owners cite: Snow and ice accumulation on LED headlight surfaces; Reduced headlight visibility in winter; Driver must manually clear buildup to prevent dazzling other drivers

Auto dimming/high beam feature flickers on and off intermittently at night without little relation to oncoming vehicles or dark highways. I have asked my local dealer twice to repair this problem, with no resolution. (see attached invoices). I also opened case with the manufacturer (Honda), and they declined to address my issue. I believe this is a safety issue because it is distracting to me…
In winter weather driving the LED headlights become covered in snow and ice. I have to keep finding a safe place to pull over and manually clear the snow and ice off the headlights so I can see properly without dazzling other drivers.
When driving on a highway, the auto dimming high beam headlight system often fails to dim the high beams when an oncoming vehicle is approaching - often causing the oncoming driver to "flash" his high beams in anger. The system will also dim the high beams when it shouldn't.- when there's no vehicle ahead of you at all. The dealership has been unable to find a fix for the problem. I find other…
Auto high beam feature fails to go to dim quickly enough when on coming traffic appears. Yet it will dim for white or yellow road sign reflections. The system is very unpredictable and causes people to flash me often. Recurring problem since new.
