I've been in touch with Hyundai regarding the pitiful performance of high beam on my 2016 Tucson. They have no answer for me. The low beam is fantastic, LED … projecting, great light coverage in front of the vehicle, however, the high beam is only marginally better, giving off an orange yellow light that I find totally inadequate on country roads. Hyundai forums would suggest I'm not the only one with this problem. Hyundai customer care says there is currently no remedy to my problem. I contemplated fitting a nudge bar with built in LED light bar, however, because my vehicle is a Highlander, the forward collision sensors prevent a nudge bar from being fitted. It may be a minor problem to Hyundai, but with the extensive country/night driving I do, if the problem isn't resolved, I'm giving thought to getting rid of the vehicle altogether, and letting whoever I can, know the shortfalls of driving a current top of the range Tucson. I hope you can help.
We contacted Hyundai on your behalf and were told that at after listening back to all their phone recordings at no point did their Customer Care say to you 'there is no solution'. They went on to tell us that if you could present the vehicle to your local dealer, they will give it a thorough check and this might point to what's causing the issue.
