The contact owns a 2020 Hyundai Tucson. The contact stated that the "Check Brake Light" message was displayed on the instrument panel, and the screen indicated that the rear brake light bulb was defective. The vehicle was initially taken to an independent mechanic where the brake light bulb was replaced; however, the failure recurred. The vehicle was then taken to a dealer where the contact was informed that the brake light bulb had failed because the bulb was an aftermarket part. The contact had the brake light bulb replaced with an authorized Hyundai part; however, that part also failed soon after the bulb was replaced. The manufacturer was notified of the failure and referred the contact back to the dealer for assistance. The vehicle was taken back to the dealer but was not yet repaired. The failure mileage was approximately 40,000.

While driving one evening, it was brought to my attention that my passenger brake light was remaining on, when I was not braking. A week later, both sides are on. This happens only if my headlights are on - automatically or if I manually turn my headlights on. The back center light will only come on when I high the brake pedals. Again, back brake lights on driver and passenger side remain on regardless of brake pedal is engaged.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Hyundai Tucson Hybrid Hev verdict →
