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.

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.

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.

Main instrument cluster and heads-up display (hud) randomly flickering, turning completely black with a "no signal" message, or triggering all dashboard warning lights.

?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.

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.

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.

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.

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.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at various speeds, the forward collision avoidance warning light was illuminated for approximately 30-seconds to 4-minutes. Additionally, while driving in the daytime, the message “headlights off” was displayed. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The failure had occurred four times. The vehicle was not repaired. The manufacturer was made aware of the failure and suggested that the dealer contact an engineer to go to the residence to inspect the vehicle. The failure mileage was 3,940.

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.

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.

Driver’s side of the vehicle that the headlight does not cover the entire road but has an angle and is a safety issue.

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.

On 08/31/2025, I was involved in an accident while driving my 2025 Hyundai Tucson. While attempting to change lanes at highway speed, the driver behind me failed to see my turn signal and collided with my vehicle. I believe the cause was the unusually low placement of the rear bumper-mounted turn signals, which creates a direct visibility flaw. The Tucson’s turn signals are mounted low on the rear bumper instead of at eye level within the taillight assembly. This design makes them especially difficult to see in two critical conditions: bright sunlight: the low-mounted signals are easily washed out in daytime conditions, reducing visibility to following drivers. Low light/traffic conditions: at night or in heavy traffic, larger vehicles and brake light glare further obscure the signals. In my case, the driver behind me could not see my intent to switch lanes, and despite my efforts to avoid a collision, the lack of visible signaling directly led to a frontal driver’s side impact. This design presents an ongoing highway safety hazard: poor visibility: low placement reduces signal recognition in both bright and low light. Accident risk: my collision demonstrates the real-world consequences of this flaw. Durability concerns: bumper-level placement exposes wiring to water, debris, and road wear, raising the risk of malfunction. Although the accident resulted in minor damage, the potential for severe outcomes at highway speeds is significant. I respectfully request NHTSA to investigate this design flaw and evaluate whether corrective action (recall, retrofit, or advisory) is warranted. Unknown if Hyundai is currently addressing this issue, but concerns about rear blinker visibility have been widely reported among Tucson owners and auto safety forums.

While driving to work this morning, at approximately 04:25, on a mountain road both my low beams failed out of nowhere. I pullover in to a turn out as my high beams still worked. I go look and my passenger low beam comes back on. I make the decision to get back on the road and drive slower to try and get down the mountain. A moment later the passenger low beam turns off as do my high beams. I do not get any warning lamps for my high beams, just my low beams. I had to drive in pitch black with my hazards on trying to find a turn out or a safe place to pull over. I was not far too from home and drove back with my hazards on. I take my low beam bulb out of the housing and see that the coil blew. I purchase two new halogen bulbs when I went to go and replace them,I found that both low beam sockets had burned. It has not been reported to the dealer as my headlights are out of warrenty by a few years nor was it reported to the police or insurance because I thought maybe all the lights died at once. I have yet to replace my high beams and I'm the only owner of it.

Vehicle: 2025 Hyundai Tucson sel approximate date of incident: [xxx] description of problem: while driving at normal speed, the dashboard display and exterior lights suddenly turned off, then reset. The speedometer and warning lights disappeared, then reappeared after a few seconds. This has happened once and I am concerned for my safety, especially if driving at night or in traffic. This issue has been reported by several other owners online, and it appears to be a widespread electrical or software fault. I am requesting that NHTSA investigate and Hyundai issue a recall or fix. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On Friday, [xxx], around [xxx] pm while traveling home my dashboard lights on the instruments panel and windshield pop up display were out, then back on, then out again, and then back on. On Saturday, [xxx], I traveled to another area about an hour away and all was fine, but on the way home it went out at least 12 times. Sometimes the dashboard light would come back up but not the pop-up display. When these go out I can not see my speed or any alerts that may possibly come up. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Was driving at night and my lights went off and the radio turned off and right back on a second later. It’s like the system rebooted. Drove fine.

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.

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.

Car uses quart 1/2 for 300miles gives no warning of lo oil level . This will lead to engine failure while driving. Dealer acknowledges consumption issues offers combustion maintenance at customer expense but service technician says save money as service doesn’t work.

Automatic headlight system causes the vehicle headlights to turn on and off during daylight conditions. The lcd display in the dashboard also dims to the point that the information presented cannot be read. This typically happens on bright, sunny days with a clear sky. Vehicle has been to the dealership in excess of seven times where they've made multiple attempts to repair it. The light sensor behind the windshield has been replaced. The body control module has been replaced. The technician also tried to make modifications to the light sensor, but the problem persists. There are a number of other instances of this exact issue involving Hyundai Tucsons, santa fe. And santa cruz vehicles shown on the NHTSA site, and also when searching other sites online. Dealer technician has repeatedly documented that the problem exists. Dealer tech reported that the tech at the Hyundai helpline suggested that the auto headlight feature not be used as a resolution. While not a solution under any conditions, even with auto headlight feature turned to off, the dashboard displays continue to dim during the day. The flashing headlights represent a serious safety issue as when following another vehicle, that driver may misinterpret the flashing headlight problem as an aggressive gesture and trigger a road rage type response. The call taker I spoke with at Hyundai when I opened a customer service case said that he personally had that very issue with another driver due to flashing headlights.

What component or system failed or malfunctioned, and is it available for inspection upon request? the airbag system, brake system, and hvac system (air conditioning and heating) appear to have malfunctioned. A dealer confirmed that the hvac system is defective, identifying a broken evaporator assembly and a faulty temperature door actuator. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? the airbag safety light raises concerns about whether the airbags will deploy during an accident. The brake light error creates uncertainty about the reliability of the brake system. Additionally, the defective hvac system is a significant safety hazard. The heater’s failure prevents the windshield from defogging, impairing visibility, particularly in cold or wet weather. This poses a serious risk while driving, especially in freezing temperatures. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the hvac system defect has been confirmed by a dealer, who provided images and recommended replacing the evaporator assembly and temperature door actuator. Independent mechanics have also observed the airbag and brake light errors but were unable to identify the underlying causes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the vehicle has been inspected by independent mechanics and one dealership but has not been evaluated by the manufacturer, police, or insurance representatives. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? the airbag safety light and brake light errors have been present since I acquired the vehicle. The hvac system began failing intermittently shortly thereafter, with the issue worsening over time. These unresolved issues continue to jeopardize the safety and reliability of the vehicle.

In the beginning of December 2024, the low headlight warning light started coming on for the right light, intermittently. I took the car to the dealership to get the light fixed, I was told there were some loose wires and they fixed it. 2 weeks later it started happening again, I returned with the car and got another appointment, before the appointment date, the left low headlight warning light came on. I returned with the car and was told that the harnesses and wiring are damaged and need replacing. I have had the drivers side light replaced on 2/26/21 and was back on 4/16/2021. The passenger side light has been replaced on 11/10/2022 and 9/21/23 all been preformed at the towne Hyundai in denville NJ.

Headlights get covered with slush and snow while driving causing you to lose vision of the roadway at night. You are not able to see creating a safety risk to you and others on the road, potentially causing an accident that would cause serious injuries or death. Yes, it can be inspected upon request. Notified our dealer and was advised that this has never been brought to their attention as a problem from any other buyer. During our last vehicle service at our dealership when notifying them of the concern no issues with the vehicle were found. Warning lamp (obstruction) appears while driving. When the warning lamp illuminates, we need to pull over (sometimes not in a safe environment), wipe the slush/snow off of the headlights and proceed traveling. After wiping the headlights off, warning lamp on dashboard returns to normal operations.

After dark, the headlights will randomly switch from auto to parking lights to headlights on or completely off. When using the selector sometimes takes a few seconds to switch from auto to off and sometimes won’t switch off. This just started three days ago. It happens while it’s parked and while driving the lights will shut off. You can use the switch to turn them on but both auto and off take a while to be selected.

Drives side headlight has a dark spot on low beam that is in the drivers field of vision. This causes the driver not to be able to see clearly. A certain portion of the drivers field of view is blocked out. Please see the picture below. Took it to the dealer for repair, he acknowledged the black spots were in the drivers field of view but, he compared it to another 2025 Tucson with the same trim on his lot and the headlights were the same. Therefore, their was nothing wrong with the lights. However, he did agree that their were black spots in the drivers field of view that would inhibit the divers ability to see clearly at night. Attached is the dealership repair order.

The contact owns a 2020 Hyundai Tucson. The contact stated that while reversing, the brake warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the brake light needed to be replaced. The independent mechanic informed the contact that the brake light housing case had melted. The dealer was contacted to purchase a new housing case. The contact purchased the part, and the vehicle was taken to the independent mechanic and the vehicle was repaired; however, the failure persisted. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

The rear turn signals on the 2023 Hyundai Tucson are on the rear bumper. They are never seen by any car or truck sitting behind you or next to you in your blindspot. I believe the 2022 & the 2024 also have this issue, and there are numerous complaints about it online, especially on reddit and auto forums. They are dangerous. Cars too close behind you or next to you in your blindspot, will never see your signal, especially the larger cars & trucks or tall autos such as buses, garbage trucks, etc. Here is one of many articles & videos about this issue: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.

Back in March 2024 I had a tow beam stock replaced to the car. Couple of months after this check engine light started coming on until it stayed on. Took SUV to mechanic shop in July 2024, and they informed of a r&r knock senor needing to be replace. A couple days after this had to go back as check engine light was back on. They informed of needing to replace a wire harness. It wasn't a week after this that when starting the car you hear a very loud knocking sound. Like something is rattling around inside. After this no longer able to drive car as not sure what will happen next.
