Electrical System Problems of Hyundai Tucson - part 1

For about a year I have had issues with my car not accelerating in stop and go traffic. I push the gas pedal and it moves a little then will not go for about 20 seconds. Sometimes the engine will flutter. I have taken it to Hyundai and was told no diagnostic codes show and they can't find anything wrong despite bringing the reports from my auto shop of these things occuring. My car is going in yet again this week because this issue continues to get worse and I have almost caused several accidents in traffic due to not being able to drive. There is a recall however Hyundai says my car is not in the recall despite the same issues the recall is for. I have all routine service done when needed and have taken care of this vehicle but I feel like Hyundai should step up because this is very dangerous not only for myself but other commuters as well. The Hyundai dealership literally said they just have the sign on their building they don't support these issues.

I was driving the vehicle at 30 mph when the power to the instrument cluster, infotainment center and headlights went out for approximately 1-2 seconds before recovering. Engine maintained power and acceleration during this period. During blackout I was unable to view speedometer nor other instrument information.

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.

All warning lights and audible alarms started going off at the same time. Eps, abs, auto hold, collision warning, air bags, all wheel drive, brake system, and more. 1st time it happened was [xxx], while driving. The car was drivable but I did notice a difference in braking and acceleration. I parked and turned off the car. I did turn the car back on several times and the alarms continued. I finally turned it off for 10 min, and all alarms stopped, but the check engine light stayed on. Car sat overnight and all warnings had stopped. Took it in for service, and issue could not be duplicated. 2nd time it happened was [xxx]. I had to have the car towed since it would not move when in drive or reverse. Alarms were still going off when it made it to service. They replaced the brake harness. 3rd time happened on [xxx], 3 days after the brake harness was replaced. Towed it to service and they replaced the engine harness. 4th time was on [xxx], 2 weeks after engine harness was replaced. This time there were no audible alarms, just all of the visual ones. Same performance issues as stated before. This issue seems to have happened to several other Hyundai owners as well, as per complaints in reddit and on Hyundai forums. There does not seem to be a consensus for what is actually causing this issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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!.

This vehicle is a pile of hot garbage. Front end collision system slams on the brakes when you are not even close to hitting something in front of you plus it will auto brake randomly but often. I was backing into a parking spot and someone walked in front of the car and it slammed on the brakes. Dealer says only way to fix this is to turn the entire safety system off. The coffee break warning has zero rhyme or reason and will go off 10+ times in a trip even though I am not distracted and use my turn signal changing lanes. Dealer states there is no way to turn this off. Dashboard randomly flashes and goes dark along with all lighting in and outside the vehicle. Dealer was unable to duplicate the problem and returned the car with no fix. Drove the car in the rain for the first time and dashboard came up with a ton of errors and crash detection turned off. This is new and will be taking the car in for this and is now the reason I am filing another complaint. This vehicle is not safe and can be very scary to drive because you don't know when it will just take over for you.

Third time SUV was parked for multiple days without being started and the main battery did not keep the charge. First time was five days and required a battery jump. Then it was 22 days, and as expected, the battery did not keep the charge and required a jump. This week it was eight days and same thing happened. I know the SUV is a hybrid but the main battery should not be run down to not be able to start the engine after a short time not being started. My brother has a 2014 Ford product hybrid and does not have any battery issues when that hybrid vehicle is not started for a period of time.

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.

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.

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.

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.

My entire dashboard goes black and I lose all directions and functions in car. It happens when driving often. Additionally after taking to dealership, it's getting worse. Now warning lights come on and stay on such as master warning lights, batteries, power steering, etc. Ac shuts off, the car misses out when driving between 25 and 30 mph. The dealership told me it's not safe to drive.

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.

My car is a 2023 Hyundai Tucson plug-in hybrid with approximately 75,455 miles on it. The car is stuck in neutral and will not switch to any other gears. The car also will not turn off fully. I basically got stuck/stranded and could not move. Had to be towed.

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.

On two occasions, the dash lights kept blacking out, along with the heads up display. On my way to the dealer for a maintenance appointment, all of the emergency lights came on and would not go away. After parking at the dealer service center, I told my service rep what happened, and when she restarted the vehicle, the lights were still on. I was immediately given a loaner. After making the repair, the mechanic asked to keep the vehicle to drive for a few days to make sure the problem didn't come back. I know these problems can reappear, even after they are fixed. I don't want to drive the car if the safety lights are all illuminated, but I also don't want to be stuck someplace without transportation.

The vehicle is currently in the shop due to safety concerns involving malfunctioning exterior lighting and a serious incident of the vehicle entering limp mode. 1) with automatic headlights activated, all exterior lights shut off while driving at night, posing a significant safety risk. 2) during daylight hours, the automatic headlight system inconsistently toggles between different lamp settings, switching off and on erratically. 3) while attempting to turn left during morning rush hour traffic (on a 40 mph road where vehicles often travel 50+ mph), the vehicle entered limp mode upon acceleration. It bogged down in the middle of both lanes, unable to exceed 13 mph, placing me in a highly dangerous position. After pulling over and leaving the vehicle off for 5 minutes, the issue temporarily resolved upon restart. 4) the vehicle is stored in a garage, and following the limp mode incident, I received repeated “door unlocked” notifications every 30 minutes from 2:30 am to 5:30 am, though the vehicle had not been accessed. These issues are of serious concern and appear comparable to conditions outlined in recall #149 and recall #236, both of which address similar malfunctions related to exterior lighting and powertrain performance. VIN# currently is not within the recalls.

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.

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.

While driving on highway going 65 mph my car 22 Hyundai Tucson sel dashboard lights turned red and shut off on the highway with no warning, was not able to put in park for 10 minutes. My safety was put at risk, the vehicle stopped mid drive on the highway with other vehicles. Dealership has not fixed or looked at the issue.

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.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the dashboard went blank for several seconds. The failure occurred several times. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 2,300.

The controls (buttons) on the right side of my steering wheel progressed from slow to respond to completely unresponsive, and then the driver airbag light started coming on. At first it was intermittent, then constant. I didn't expect those two issues to be related but did come to learn it was the clock switch. According to my Hyundai dealer, this is a known issue in several other years/models of Hyundais and they have extended those warranties, "but it hasn't reached the Tucson yet". I was told that either 1 - my airbag wouldn't deploy or 2 - it would deploy randomly when I was driving the vehicle. I spent nearly $1000 in diagnostics and repairs.

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.

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 bought the car used, I took it in for diagnostics on my transmission. They claimed I needed a new one, not claiming I need a new clutch. My car’s model and year match the dct recall problems. But not the VIN. When my car was in the heat or accelerating it had the same issues listed. I believe this is a manufacturing issue.

While driving I noticed my abs, traction control, aeb, and a couple of other lights came on. Upon restarting my car it was still there but the lights went away on their own after a few minutes of driving. They have been periodically turning and and off as I've driven the past couple of days. I went to the local mechanic shop who performed a diagnostic and found it to be a faulty left rear wheel speed sensor. When researching online, I've come across many people with the same make, model, and year as my car that have experienced this issue.

The contact owns a 2019 Hyundai Tucson. The contact stated that while at a red light, the missing key warning light illuminated. The check engine warning light illuminated. The hazard lights were independently deactivated. The contact became aware of an abnormal odor and smoke on the interior of the vehicle and the exterior of the vehicle. The contact stated that all the door latches were independently locked, and the engine seized. The contact stated that her minor child was also an occupant of the vehicle at the time of the failure. The contact stated that a nearby police officer and other bystanders assisted with removing the contact and the minor child from the vehicle. The contact stated that it was a very traumatic experience, and the contact was very fearful for the lives of her minor child and herself. The contact had a doctor's appointment scheduled; however, because of the failure, the appointment had to be rescheduled. The vehicle was towed to the dealer; however, the vehicle was not diagnosed. The contact was offered a trade-in option. The contact declined the trade-in option. The manufacturer was not made aware of the failure. The failure mileage was approximately 52,000.

1. 2 sundays ago the car just slowed to almost a stop while driving. The radio turned off and the lights on dash came on. Took to service next morning and of course they couldnt duplicate problem. 2. Last week, the radio blacked out.

While driving, without warning, all malfunction lights came on the dashboard and stayed on, including check engine light. The speedometer and rpm show as zero even though I’m moving. The power steering locks up. Scary as hell! this has happened 5+ separate times within the past 2 months. The first time I had it towed to the dealer and they said it was caused by a karr alarm that was pre-installed by the dealer prior to my new purchase which I never authorized and was never activated. They said it was causing a short even though it happened 2+ years after purchase. It was removed by the dealer for free and the electrical issue happened again the next day while driving. It was towed to the dealer again and after a week the car was returned to me with no diagnosis as they were unable to replicate. It happened 2-3 more times and I got it towed to the dealer for a third time as I don’t feel safe driving this car at all. I am scared the car will die while on the highway. Car still at dealer.

The contact owns a 2025 Hyundai Tucson. The contact stated while driving approximately 35 mph, the instrument cluster went black; however, the radio was still playing. There were no warning lights illuminated. The contact stated that the failure was intermittent and occurred while driving at various speeds. The contact stated that occasionally the failure lasted for 20 minutes before the instrument cluster returned to normal function. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the coaxial cable needed to be adjusted. The vehicle was repaired; however, the failure reoccurred. The contact had taken the vehicle back to the same dealer who diagnosed the vehicle and informed the contact that the instrument cluster wiring harness needed to be replaced. The vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 5,000.

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.
