Hyundai Santa Cruz headlights problems

Filed Oct 29, 2026 · Electrical, Lights · TX

One or two times a week, while driving at night, my headlights and head unit display both power off briefly, typically about 1/2 a second. Then they resume as if nothing had happened. No warning lights or errors, no boot up screen... just back to normal instantly. The only thing that changes is my seat belt indicator illuminates for a few seconds, then goes back off. After some online digging, it seems plenty of other people have this issue, but no one has found an official cause or solution.

The vehicle was repaired, but the failure persisted. The vehicle was taken back to the same dealer on several occasions. The dealer ultimately deemed the headlight performance normal.

While driving at night I happened to notice that the headlights failed to illuminate the road sufficiently. Specifically, the truck was going downhill. As it approached the bottom and soon to go uphill, I noticed that there was a strict delineation in what was lit up and what was not. Being on a country two lane with no ambient lights and travelling at the posted 55mph I realized that I did not have enough distance to stop safely in the event that something be on the road ahead, e.g., deer. So concentrated is the light that it does not create any vertical illumination. (Picture travelling toward the bottom of a parabola.) I visited the Hyundai dealership in my area the next day. I asked that the headlamps be adjusted (raised) to extend the field of vision. The Service manager told me that there is no adjustment for my headlights. I explained my experience driving without adequate illumination. He did not offer any recourse other than to slow down. I have never had a vehicle that did not have headlight adjustment capability.

Another driver ran a red light and hit a vehicle in front of me, which spun and impacted the right front corner of my truck. Impact did not seem that severe, my air bags did not deploy but both front seat belts were locked up after the accident. My damage seemed just cosmetic, grill, bumper, hood and right front fender & headlight were damaged. At repair shop, they determined that the right front frame rail was damaged and the vehicle is totaled, almost $19,000 to repair which is above Geicos’ 75% limit. If the impact was enough to damage the frame rail, why didn’t the air bags deploy?? I do not have an electronic copy of police report or damage assessment, only paper copy.

Vehicle is equipped with automatic headlights. They constantly turn on and off during the day as soon as you enter any type of shadow. This causes the headlights to “flash” the driver in front of you. While traveling on the interstate at 75 mph if you go under an overpass they turn on, less than 1 second but take 30-60 seconds to turn off! During that time the dash darkens and you cannot see the speedometer,HVAC controls, etc. Even with the headlight switch turned to OFF the dash continues to dim as if the headlights were on! I have had the dealer (San Tan Hyundai in Gilbert AZ) check them twice. Each time I am told operating as designed. This needs a software update to make the automatic headlight system less sensitive. There is no reason why my dash is dimming while the system is off or why the headlights are coming on during a bright sunny day because I drove through a shadow.

The most major problem that occurred on 2-3 different occasions is that the emergency braking system activated for no reason on one occasion, almost causing a Rear end collision with a person behind me. No one to my sides, and in front of me on all of the occasions. Headlights on the automatic, setting on a bright sunny day, will turn off and on no change in lighting which annoys other drivers because they think I’m flashing them. After starting the car in Drive the first time I break and then go to accelerate there’s a delay in the acceleration. as well as other times while driving. Today, the back up camera didn’t shut off when shifting into drive like it normally does it didn’t go off until I went into parking pushed the radio button. I’m pretty sure it’s a computer issue

*Headlights are not shining correctly. Traveling on a two lane highway, a big black spot covers the whole left lane, about 75 yards. No black spot on traveling lane Driving on a curve road in a subdivision, your eyes follows the black spot , instead of paying attention the road. This is a bad scenario for a accident. I do not know if oncoming traffic sees the black spot or not. *This has a known safety issue that was not disclosed to me at the time of purchase. It has been well documented all over the Internet since 2021. The service manager and sales manager confirmed that it is a manufacturer issue. This particular model cannot be resolved.

My LED headlights have a massive dark spot in the top left corner. It looks like a triangle took a bite out of the light. It creates a big blind spot at night when driving in poorly lit areas and again, Hyundai won't do anything about it.
