The worst model year for it is 2016.
This problem was observed about 1 month ago: While driving and headlights set on AUTO, during the day, and the light switch NOT on, the dashboard would indicate the lights were ON, for just a second or two, and would go off. At night with the headlights set on AUTO and the headlights ON, while driving, the headlights go OFF and ON briefly (1-3 seconds) causing a dangerous situation as visibility of road is lost. This condition was initially observed at night, after using the turn signals (left/right), but is now happening with greater frequency while driving without using turn signals. I Will schedule a visit with dealership to report/confirm problem.

I have a 2024 Hyundai Tuscon SLE that I purchased new and several months ago there was a recall on the trailer hitch wiring. I took the car to Hyundai and they removed the wiring harness hitch due to a fire danager. Todate I have not received a replacement hiring harness, so my vehicle is now useless for pulling a trailer for several months. (The spring and summer months are when I use this the most and have not been able to.) All I hear from Hyundai is that they do not have a cure for this. I notice that the 2025 and 2026 models have a wiring harness on them that do not need replacing. I need something done ASAP regarding this matter. Why has NOTHING been done regarding this replacement? It has been MUCH TOO LONG! Is there ANYONE at your organization that can help me with this matter ASAP!!!! Thank you.
NHTSA complaint #11756451 — an unverified report by a vehicle owner.
The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at various speeds, the Forward Collision Avoidance Assist (FCA) warning light was intermittently illuminated. The dealer was notified of the failure and attributed the issue to inclement weather. The contact stated that while stopped, the vehicle was rear-ended because the brake lights failed to illuminate. The contact sustained lower back and shoulder injuries, was transported by ambulance to the hospital, and required ongoing injection treatments. A Police report was filed. The vehicle was towed to a dealer and repaired for rear-end and passenger-side damages; however, the cause of the brake lights' failure was not determined. Additionally, the contact stated that while attempting to accelerate from a complete stop at a traffic light, the vehicle stalled and was struck on the front driver's side by another vehicle. The crash caused the vehicle to spin, and the front end detached. The air bags failed to deploy, and a system failure message was displayed. The contact sought medical attention the following day. The contact sustained a dislodged left thumb bone which required surgery, a cast, and injections for left arm pain, as well as shoulder, neck, hip, and aggravated lower back pain. A Police report was filed. The second failure had occurred at [XXX]. The vehicle was towed to the auto body shop at the dealer and repaired; however, neither the dealer nor the insurance adjuster determined the cause of the vehicle stalling. The contact associated the failure with an unknown recall notification. The manufacturer was not notified of the failures. The failure mileage was unknown.

NHTSA complaint #11755414 — an unverified report by a vehicle owner.
While driving at night, the headlights on my 2022 Hyundai Tucson Hybrid shut off randomly, including when using the turn signal. The lights will turn off without warning at highway speeds, creating a serious safety hazard. Using the turn signal can cause the headlights to turn off, and sometimes using the turn signal will temporarily turn them back on. The headlight mode also changes by itself while driving (AUTO to OFF to ON to OFF). Additionally, when the vehicle is turned off, the headlights often stay on no matter what mode the switch is in. I have to restart the vehicle and manipulate the turn signal/headlight stalk multiple times to get the lights to turn off. This is a recurring and dangerous failure that affects nighttime visibility and safety for me and my family. No other electrical issues are present. This is available for inspection. Safety for my family and all others on the road put at risk as the headlights randomly shut off at night. The problem was reproduced by the dealer. The dealer quoted a $1,500 repair, but this a safety‑critical defect in the lighting control system.

Good morning the problems I am having with my 2025 are very discouraging. Started October of 2025, my tire light illuminated stated the tires were low when they are all at correct specs when using an air guage to check. November of 2025 while driving at night the headlights suddenly shut off briefly then came back back on. January of 2026 while leaving work the transmission would not shift, held accelerator pedal to floor but could not go above 20 mph all the way home for 3 miles. April of 2026 the right side of navigation screen went completely black, shut vehicle off twice and on third restart the screen reilluminated. June of 2026 same thing with the screen going black. I have had my Tuscon at the local dealer here in my town for supposedly a repair that they state was a "coaxel cable" behind the dash that was fixed that was causing this issue. I also had the recall performed for the front view camera software update but it is still showing not completed. This is very frustrating to be having experiencing these kind of issues on this new of a vehicle. Clearly something is going on with the software or something and the dealer keeps telling me they are not finding anything wrong. I am a service advisor myself at a small independent shop so I understand the terms they are using but something needs to be addressed to correct the issues that I am having. It is scary when driving and the screen goes black or driving at night and losing the headlight functions. I would appreciate if somebody will look into this and reach out to me to get some kind of remedy for why this is happening. I am paying alot for this vehicle and to say I am satisifed is an understatement. I have purchased Hyundai as my choice of vehicle due to the quality, great warranties and good reviews from other consumers however I am seriously thinking of exploring alternative makes as I do not want to keep going through this. Plus the engine consumes oil. I have attached p/w for review as well

NHTSA complaint #11747548 — an unverified report by a vehicle owner.
On my 2026 Hyundai Tucson Limited, the HVAC touch-panel status indicators are extremely difficult to see in daylight conditions. The illuminated indicators for A/C, recirculation, vent mode selection, and heated/cooled seat levels become washed out by sunlight and reflections. From the normal driving position, the indicators are often not visible. To determine the status of HVAC functions, I must lean forward and/or shield the panel with my hand to see the illuminated indicators. This requires additional driver attention and time looking away from the road. The condition occurs even with instrument panel illumination set to maximum and display settings to maximum. We had the suv at the hyundai dealer and showed the service adviser the problem and he agreed is was a design problem. It is especially a problem in lots of traffic these days when you have to lean over/closer or cup your hand to see the settings which requires taking your eyes off the road and your hand off the steering wheel for a long period of time, creating a distraction and safety concern.

NHTSA complaint #11742863 — an unverified report by a vehicle owner.
Before I owned this car, I used to get so frustrated whenever I was driving behind this type of vehicle because the rear blinkers are mounted so incredibly low in the bottom bumper that you can't see what the driver is doing. Now that I actually own a Hyundai Tucson, I feel completely responsible for the drivers behind me. Because I know how low my blinkers and reverse lights are, I have to turn them on way before I actually turn, and I'm always worried someone will hit me when I'm in reverse. On top of that, my friends who drive behind me constantly tell me how bad it is and how hard it is to see my signals because of how low they sit.
NHTSA complaint #11739615 — an unverified report by a vehicle owner.
Rear turn light visibility, turn signals are a foot off the ground and hard to see by cars following due to location on the bumper. This is only pertaining to the 4th generation Tucson (current), not any other generation. We didn't realize the issue when we bought the car, nor did we realize the placement in the bumpers. However someone stated it was hard to see the blinkers, especially in the rain. At first we thought the wiring had come undone, but then we noticed the same issue on all 2025-2026 model Tucsons. Then I noticed this video on Youtube and realized it's been a problem. This gentleman seems to have a fix, which imo should already be done, maybe Hyundai accidently missed the hookup when making the vehicle. It seems the brake lights were meant to be hooked up as blinkers and the rear horizontal line light was to be a part of the braking lights. Anyway the way the current blinkers a placed is where the backup lights should be. Please help with this, it's definitely a safety issue in the rear back and or rear quarter side panel turning of the vehicle. Visibility is very poor to say the least.

The HUD and dashboard on 2025 Hyundai tucson hybrid restart intermittently during driving, often during temperature change (e.g. from an indoor parking lot to outside) or on bumpy roads. Sometimes the HUD and the dashboard black out for a while during driving, making it impossible to determine the speed and vehicle conditions. This is threatening to safety on highways. This first happened on my new vehicle at about 5000 miles and was confirmed by a dealer. The dealer replace the main wire harness and the problem went away for a while. Now it comes back at about 8000 miles.
NHTSA complaint #11721678 — an unverified report by a vehicle owner.
The heads up display and dashboard display go black while driving. Sometimes it flickers on and off repeatedly which is very distracting while driving. When it is off, I cannot see speed, fuel, etc. A recall was issued for this problem, however my vehicle VIN was not included in the recall, meaning the dealer will not address it. Additionally because it happens randomly it is impossible for the dealership to recreate it with the small amount of time they can allot to driving it try to recreate the issue. Because the dealership has not been able to reproduce the issue, it continues.

Brake lights, hazard lights, and turn signals in the back of the car stopped working. Took vehicle into Glenbrook Hyundai dealer in Fort Wayne, Indiana and the dealer confirmed the problem is caused by the open safety recall. No remedy exists yet, so dealer charged me diagnostic fees for recall-related work.
NHTSA complaint #11709015 — an unverified report by a vehicle owner.
Issue Type: Intermittent Electronic System Failure / Critical Safety Hazard Description of Incident: A severe safety-related incident occurred while driving at night on 12/29/2025, at approximately 5:48 pm. Under fully dark winter conditions in MA, while the vehicle was in motion with the headlights set to AUTO, the following events occurred: Total System Blackout: All interior and exterior lighting systems suddenly failed simultaneously, including the digital instrument cluster, infotainment display, and backlighting for all illuminated buttons and controls. The complete failure of exterior lighting and interior displays resulted in an immediate loss of forward visibility and access to critical driving information. Duration: The blackout lasted approximately two seconds before the system appeared to reboot. Recurrence: Approximately ten seconds after the first incident, the same total blackout occurred again under identical conditions. Vehicle Status: The engine remained running throughout the incidents; however, the simultaneous loss of lighting and instrumentation created an extremely high-risk driving situation. This incident constitutes a critical safety failure. The vehicle had experienced repeated electrical system failures prior to this incident, and was previously presented to the dealer on 8/7/2025 for diagnosis and repair. The dealer was unable to determine the cause of the malfunction and failed to take appropriate corrective action to address these issues: 07/13/2025: The Auto Stop function became inactive, and the vehicle failed to accelerate properly after stopping at traffic lights, creating a hazardous driving condition. 07/14/2025: The phone failed to connect to the vehicle’s infotainment system. 07/17/2025: While reversing in a parking lot, the Parking Collision Warning system failed to detect a moving vehicle behind the car. No audible or visual warning was issued, rendering the safety feature ineffective in preventing a potential collision.

I am filing a complaint under the NC Unfair and Deceptive Trade Practices Act (N.C. Gen. Stat. § 75-1.1) regarding Hyundai’s handling of my 2018 Hyundai Tucson (purchased new May 2018). Since 2019, the vehicle has had repeated headlight failures (at least 12 bulb replacements), persistent “bulb out” warnings, and eventually melted wiring requiring headlamp assembly replacement in 2025. These issues were first reported in April 2023 under warranty but dismissed as “could not duplicate.” Hyundai later attempted to deny coverage, only replacing the assembly after escalation to Corporate. At the April 2023 visit, I also reported a rear noise that Hyundai dismissed. After warranty expiration, it was attributed to a leaking shock. Shocks were covered under warranty; failure to act while coverage was active left me unprotected. In May 2023, the engine failed due to oil loss and lock-up. Hyundai retained my vehicle from 5/15–6/30/23 for engine replacement. From Aug–Sep 2025, the car was held an additional 24 days, with no permanent fix for the electrical defect. Overall, my Tucson has been out of service for 60+ days between 2023–2025. Examples of unfair/deceptive conduct: Dismissing documented defects under warranty, only acknowledging later after expiration. Attempting to shift labor costs onto me in Jan 2025 despite warranty obligations. Returning my vehicle with only ~39 miles of gas after requiring me to return a loaner full. Repeated misdiagnoses and delays despite video and documentation provided. These actions are deceptive and unfair, leaving me with an unsafe, unreliable vehicle and causing financial loss and hardship to my work as a self-employed pet sitter and dog groomer. I request the Attorney General investigate Hyundai’s conduct and enforce consumer protections under UDTPA. Service records, receipts, and communications are available upon request.
NHTSA complaint #11690889 — an unverified report by a vehicle owner.
The rear brake lights and turn signals on my 2025 Hyundai Tucson are not visible to following drivers due to their low placement and design. Multiple drivers have nearly rear-ended us because they could not see when I was braking or signaling. The lights function electrically, but their position makes them obstructed and not noticeable from normal following distances. This is a serious safety hazard and creates a high risk of rear-end collisions. The dealer confirmed the lights work as designed but cannot change their position. This is a design defect that cannot be repaired and should be investigated for recall.

Both Headlights suddenly became very dim WHILE I WAS DRIVING. On normal lights there is almost no light beam coming out at all, and on bright lights there is slightly more lighting, but there is also what looks to be a large shadow across the light beams. I’ve had it checked and there are NO bulbs burnt out.
