2025 HYUNDAI TUCSON HYBRID Electrical System Problems

Intermittent flickering of the infotainment + backup camera screen. The screen displays glitching bands of static, loses touchscreen functionality, and reboots on its own. The flashing light presents a significant safety hazard when driving at night. Dealer has tried replacing the head unit and adjusting the coaxial cable with no success.

Vehicle propulsion system failed, as a result vehicle rolled down an inclined driveway in to the street and was stuck in the middle on the street in traffic. Vehicle had started normally, was able to shift into Drive, no obvious warning lights or error messages displayed. Vehicle would shift into Drive/Park/Reverse as required but would not move. Upon shutdown an restart two warning lights were display but Vehicle would still not move. Vehicle only had 168 miles on the odometer. Vehicle is a Hybrid, engine was running and Battery charged. Apparently the problem was a failed "Over the Air Software Update", this was corrected by Dealer (see attached file). Safety issue is that the Vehicle, 1 Failed to display any error regarding a Failed Update, 2 Failed to immobilize the Vehicle allowing to move in an unsafe state, 3 Failed to notify Owner that Updates had been done, 4 Proceeded with an over thew air Update that could potentially place the Vehicle in an unsafe state.

While driving, the digital cluster (unit that displays speed, fuel etc) goes blank many times and this is a major safety issues as critical info is unavailable and also very distracting while driving as the unit flickers and reboots during driving. Here are a few videos of the issue: [XXX] I took the car to dealership where they replaced the cluster module but i still am facing the issues even after repairs.

My vehicle was purchased new and has less than 5100 miles on it. The screen and heads-up display randomly begin to glitch and then simply go dark. I can't see my speed, fuel or charge levels or any important data while driving. This has happened multiple times already. My vehicle is a 2025 model. Interestingly, Hyundai had the same type issue on 2024 models and issued a TSB to resolve this issue, but have not issued any repair for the 2025 models. This is a major safety issue.

The electronic dashboard and heads up display go blank for as little as a few seconds to over 30 seconds. This happens over and over again. Sometimes in doesn't happen at all but more often than not it does. I have no data when this does this, no idea what speed I'm going at, no data about the blind spot safety controls. Nothing. If it unsafe to drive without knowing what speed you are going and other information. The dealer said they could not reproduce the condition even though there is a Hyundia Technical Service Bulletin out for the same problem on a similar Hyundai and many, similar reports on the Hyundai forum. The dealer said they could do nothing even though I had to drive off in an unsafe vehicle.

To be honest, this could have been happening for months and I just didn’t pick up on it. I typically look out the front window and use my heads-up display. I’m very rarely looking at the gauges while I’m driving down the street so this just happens to be when I began to notice it. 9-4-25 near 4 PM Left side screen where gauges are located blackout -it didn’t last long, but it did frighten me and then it did it again and the second time it did like a restart because it came up with the ready to drive message 9-6-25 10:40AM left side of screen black out 9–16–25 7:13 AM. Left side screen where gauges are located blackout a second time at 7:12 PM 9-18/25 4:45 PM left side of screen black out 9-20 -15 10:45 AM left side screen where gauges are located blacked out 11:24 AM all gauges lit up on dashboard I don’t even know all these signs. These are the ones I recognize battery, brake, auto hold, ready, number of caution signs, airbag sign, AFS, ABS EPB (image uploaded showing the car in drive) I turned off the vehicle. The lights remained on restarting the car made no difference. The next day car started normal no access dash lights Took the car to the dealership on Sept. 23, when I made the appointment, they acted like they had never heard of this happening ...however when they called to discuss my car they said they have had several come in with the same issue. They stated they needed to replace a wiring harness, but it is on indefinite backorder according to the service person. I think his name was [XXX] . They were unable to tell me when they will be able to address this concern. I am concerned this sounds very similar to the Toyota's that are being recalled and if both companies need the same part how safe are these cars from Hyundai to drive.

The backup camera is not working and theres a glitch on the screen when on reverse gear. In addition the adaptive cruise control is not working 8-9 out of ten times.

Hybrid System Failure at 4,052 miles. HPCU replaced. Issues remain. Recommending replacement of hybrid battery. DTC codes: P1A9096, P0B3B00, P0A0A12 Dealership has all the maintenance records as this is still unresolved and vehicle remains there.

Intermittent failure of HUD and instrument cluster. HUD disappears from view and instrument cluster goes dark. Unable to read speedometer and information. All warning lights are lit. Cluster has a message no signal. Dealer has on order a replacement wire harness. Problem started after 1 month and 1000 miles. Replacement part on back order will take several weeks. Loaner car has been provided. No injuries or property damage.

I have had two incidents with this vehicle (that I have owned for less than 90 days) that have raised safety concerns. Both involved the loss of all information on the "instrument panel" AKA dashboard. In the first (August 18, 2025), all of the warning lights came on, then the screen went dark - there was no information on the two screens and no head's up display. This happened while I was on the highway doing about 65 mph. After I was able to pull over safely, it took several attempts to get the vehicle started again and in gear. I took it to the dealer the next day and they were unable to replicate the issue and saw no codes. The second episode occurred yesterday (9/6/25). This time the screen went dark except for a large red warning "NO SIGNAL". The screen came back after a few moments; I am taking it to the dealer tomorrow. Both of these involved losing all information as to the speed of the vehicle - which I believe is a safety issue. Both of these issues have also been reported by others on Facebook ("Hyundai Owners") since late last year and it appears to be some sort of electrical issue but there has been no TSB or recall by Hyundai yet.

Heads up display and gauge cluster will intermittently flicker and/or reboot. When gauge cluster comes back on it will sometimes have all warning lights stay on. Have had it happen once where gauge cluster rebooted and then flashed "No Signal" while repeatedly rebooting. Both HUD and Gauge cluster do shut off together sometimes so I am no longer able to see my speed when that does happen

The instrument panel side of the infotainment screen has gone completely black on multiple times . The heads up display flickers and goes out, therefore, no way to see what speed I’m going.. extremely dangerous.. also all warning “dash” lights come on. I have A video of the dash lights on and the screen going black and coming back on.. I dont Make it a habit of driving with phone in hand. Your system will not let me upload my videos!

My dashboard will black out, my HUD display will flicker or just go out. All of my indicator lights for vehicle issues all light up and stay lit up.

The contact owned a 2025 Hyundai Tucson. The contact stated that while the vehicle was parked and turned off, the rear of the passenger seat caught fire. The vehicle was unoccupied at the time of the fire. The fire was extinguished twice by the Fire Department since the fire reignited after the first time the fire was extinguished. A fire report was filed, and a report number was provided. The cause of the failure was determined to be a lithium battery failure. A police report was also filed. The dealer was contacted. The vehicle was not diagnosed or repaired. The vehicle was destroyed. The manufacturer was made aware of the failure. The failure mileage was approximately 800.

Mileage: 800

Instrument display and head up display go off and on at random times. Occasionally both are off at the same time so I can not see how fast I am going or use the video feed when signalling to turn. At times, all warning lights are on and do not go off so I am unable to tell if there is a problem with the vehicle.

The Heads Up Display and Digital Instrument Panel suddenly go blank as if switched off resulting in no speedometer, tachometer, malfunction indicator lamps, temperature gauge, TPMS, and integrated ADAS components including lane keeping, blind spot monitoring, adaptive cruise control, 360 camera functionality. These failures are intermittent and can last for seconds or minutes while operating the vehicle. Onset seems to be related to ambient temperatures, routine ride disturbances, acceleration and deceleration activities in the normal course of vehicle operation. The issue has been a topic of discussion on several online owners forums. Owners report that Hyundai dealers have attempted to resolve this issue unsuccessfully with harness replacement, pin and connector retensioning efforts, and display replacement.

I was driving my new 2025 Tucson on a 2400 mile trip. On the way back the entire dashboard went black and I got a big red notice. No signal. Could not see anything. No speedometer no nothing after while a black screen went away and I got the regular screen back but it had all of the fault lights lit up. This happened periodically through the whole trip. In addition, the heads up display worked periodically only. And I could not use the cruise control as it kept telling me that it couldn't see my eyes. Although I did not have any glasses on at the time. I feel very unsafe with this car. It is at the dealership waiting for new wiring harness but as I see in social media this has happened to many other people. I think this is something you should know about.

My HUD was going off and on, especially on bumpier roads. This could happen several times on a drive. At least once, when the HUD went out, the dash lit up like a Christmas tree (all the warning lights came on), and a couple times it went totally black. I took it to the dealer and they diagnosed a bad head unit, and am awaiting parts.

Dashboard and hologram in windshield went off - repeatedly went out when I hit bumps and then eventually caused all dashboard lights to come on even when the car was off (7/22). Subsequently dashboard cluster was replaced and repaired on (7/30) same day in the evening it began doing the same thing again. Hyundai notified again of issue on 7/31. Car purchased in April of 2025

Main dash (with speedometer and other driver notifications) and HUD went black. Blinking "No Signal" on 7/27/2025. Came back on after extended power off, but is flickering in and out when I go over a bump. All warning lights will light up, or the screen will go blank with "No Signal" or restart as if I had just turned on the car. HUD comes in and out. Infotainment is working fine.

The heads up display and dashboard turns off and on, sometimes going black for 20 min at a time. This results in not having a speedometer or gas gauge, which makes it an unsafe vehicle to drive. Dealer has not been able to fix, despite multiple repair attempts. There are many Hyundai Tucson Hybrid Limited owners reporting identical issues online. Identification of affected vehicles, determination of an effective repair, and recalls are needed to ensure safety.

While driving, my entire dash will go black. At times, all warning lights will also light up. There is no way to know how fast I am going since the display shuts down. Heads Up Display also goes out with warnings as well. With all warning lights coming on, there is no way to know if there is truly an issue with the car. The car was taken to the dealership and the cluster was replaced. This did not fix the problem. The car is now back at a dealership with no answers. I do have a case opened with Hyundai as well. Case # 41048985. I am a part of a Facebook group were an additional 19 people have also said they have experienced the same issues. There seems to be no real concern from Hyundai. Safety Risk - speed visibility, warning lights, overall safe operation Problem as been confirmed by the dealership No issues with the vehicle prior to this

There are several electrical issues occurring that have put me in danger when driving. First the screen both on the windshield and the speedometer screen randomly go out completely and I have no idea how fast I am going or any other important features like how much gas my vehicle has, if the vehicle is over heating. The forward/ break feature has gone off multiple times and the vehicle has stopped in the middle of traffic and the freeway with zero warning and with several car lengths between me and the car in front of me. Almost hit from behind when this happens and has put the vehicle in park on the freeway. Steering wheel has jerked to the side when driving making the vehicle almost hit curbs and other vehicles. Has come back to my vehicle that is off and locked and the ac has been running causing the engine to be hot. All the warning lights have turned on and won't go off even after stopping and restarting the vehicle. The vehicle is currently at the dealership with them having to answer to the problem, stating hyundai is aware of the issues but does not know how to fix it. I bought the car in April 2025 and there is just under 2800 miles on the vehicle.

I purchased a new 2025 Tucson Limited Hybrid model. I owned it for five days when the dash display went blank, leaving me without any speedometer, warning indicators, or safety features, such as lane departure warnings. There is a manufacturers bulletin on this defect. Took it back to the dealer, and they tried to sort it out. They kept the car for a week and indicated that it was fixed. I picked up the car, and in 2 blocks it did the same thing. Car is now back at the dealer. I believe this is a significant safety concern, as all safety features should be visible, especially the speedometer.

I think when its hot like in illinois its been super hot the screen keeps going black!! I can't see the dashboard i called my hyundai dealership will get it looked at seems like I am not the only one dealing with this issue. Main screen on left goes black or it has problem logos on it randomly.

1 forward collision unexpectedly slammed on the brakes when I was trying to go forward to make a left turn. There was no one in front of me nor each side of me. I had 2x4’s in my car that were thrusted forward damaging my dashboard and display. I was told to take it to the dealership on Monday 2 I was fine just hooked up, but the driver was pissed off at me thinking I was stopping short on him 3 randomly the rear sensor would go off telling me they are too close when I’m at a complete stop. It has randomly stopped short on me but I thought it might have just been an over sensitive sensor. I have previously owned an Ioniq 5 and the sensor would never stop going off even if I was 2 car lengths away. 4 the car is going back to the dealership on Monday so it has not been expected yet 5 exactly 6 days after purchasing the car the airbag indicator showed up on my dashboard while I was driving. I was used to the Ioniq 5 sensors always going on when I was stopped waiting for a green light that I just thought it was the same way. It had abruptly stopped on me three other times between the 6th and today the 21st. I have only had it for 3 weeks. I have never gotten any warnings before the car just slams the breaks on. After looking online about this issue I decided to make a report before I take it to the dealership so you have it on file. I am very disappointed with this vehicle and was so excited when I bought it. I have been a loyal customer of Hyundai since 2017 when I bought my first Ioniq and I have purchased 6 other cars for my family members since then. I still purchased the Tucson after having to take a 15,000 loss because the Ioniq 5 never held its value. Now I’m wondering if I should switch manufacturers

Battery Management System failed Safety-Could not drive on interstate. Very unsafe. Dealer inspected problem afterwards. Warning lights appeared at time of problem. No warnings before. No signs of problem before it happened. SYNOPSIS: After driving through a torrential thunderstorm on the interstate (06-13-25) and as we were getting ready to slow down for our exit on the interstate, we hit the brakes and our SUV gave us a warning. The warning said, "Battery Management System Discharge". The SUV is a hybrid. At this point the SUV locked into E V mode. Our SUV would only go 10 mph which was very dangerous. It should be able to go up to 35 mph in E V mode and then past that, switch into gas mode. As stated, we could only go about 10 mph. We made it to our exit and found a spot to pull off the ramp. We let the SUV sit for a few moments and turned it off. We let it sit for a minute and then turned the car back on. The SUV when we turned it back on gave us a check engine light and still would not go over 10 mph. Luckily we were stopping for dinner. We were able to proceed to our destination. After dinner around an hour or so, when turned the vehicle back on, the SUV still gave us a check engine light. but was able to drive normally and switch between E V and gas modes. We made it home safely at the end of the weekend on 06-15-25. On 6-16-25 we took the SUV to be looked at by the dealer we purchased it from. Our phone app showed code DTC P0AA600. We gave the code to the staff. The staff inspected the SUV. The report stated, "customer states stopped driving and there code P0AA600 Battery Warning Light NPF Could not duplicate problem. Tech scanned for codes Code P0AA600 was found as a history code. Tech checked live data and everything came back within spec. Followed the flow chart procedure for the code. Check for BMS isolation faults none found. Check 12volt battery. Battery is good". We drove it home and filed this report.

The Driver Attention Warning is a dangerous feature that can't be turned off. It is constantly going off requiring that I take my eyes off the road to see why it chimed. I am a Disabled Veteran with an eye condition that requires me to wear very dark glasses in bright sunlight. The car is not drivable with my glasses on as the camera can't see my eyes. I was almost involved in a serious accident on I459. As I drove between an 18 wheeler and another SUV a red light on the dash and a message flashed that stated "Regain control of the car". The system slammed on the brakes which caused the car behind me to almost hit me at 70mph. This occurred in heavy traffic at approximately 8:30 AM. I almost lost control of my SUV.

The Driver Attention Warning continues to go off shutting the cruise control off. This happens continuously and is a safety issue when driving in traffic and the vehicle suddenly decelerates. This causes traffic behind you to almost reared you because the vehicle decelerates so quickly. Hyundai suggests to move seat, not to wear glasses and other options that in themselves are additional safety concerns as seat positioning and glasses are needed for driving. So far my car has had the sensor located on top of the steering column shimmed up, and wiring harness replaced all to no satisfactory conclusion. Hyundai is aware of the issue, but has no solution to the issue. I’ve been in a loaner for almost 2 months while they string me along looking for a solution. Something needs to be done to fix this safety concern.

I purchased a brand new 2025 Hyundai Tuscan and with 984 miles I had an issue which first started when reversing the SUV into my garage. December 9th: When first starting the vehicle, all warning lights came on the dash. The ABS stating an issue with the braking system. I experienced a dead pedal and no power steering. After restarting the car all the lights went off and the car returned to normal. Code: DTC C165686 and DTC C162587 December 10th Error: Check driver assistance system While driving the vehicle which had no errors on start, the error came up again but this time power steering was available and the brake pedal appeared to be working. Originally, the Hyundai dealer would not be able to assist until the following week but after calling them and expressing safety concerns they immediately took the car and put me in a loaner. Code: DTC C165686 and DTC C162587 It’s Jan 3 2025 and the vehicle has been waiting for a replacement hybrid battery. The manufacturer told the dealership weeks ago that the error is due to a bad hybrid battery.
