Electrical System Problems of Hyundai Tucson - part 1

Car often does not accelerate when hitting the gas. Was turning onto highway from a stop car did not accelerate causing other vehicle to swerve to avoid hitting me as my car would not move. Couple seconds later it moved.

The faws forward assistance warning system incorrectly identifies a "sleepy driver" and turns off adaptive cruise control. Faws has a dozen triggers that will cause this system to incorrectly alert the driver that his eyes aren't looking at the road and it turns off acc. The faws has a turn off switch but it does not turn it off. So, without this safety feature of adaptive cruise control, the driver just gets constant alerts to stay alert. Hyundai claims it is working "as designed" and has a suggestion to invest in specific sunglasses, or not be taller than 6'1" so the eyes can be detected, or don't wear a hat. Seriously, these are in the manual.

As I was driving I was stopped & told my car was on fire. I immediately stopped & hopped out & less than 30 seconds later half of the hood caught heat/fire & flew into the windshield breaking it. At least half the car is burnt to ashes.

The contact owns a 2020 Hyundai Tucson. The contact stated that upon starting the vehicle, the brake auto hold was engaged unintendedly and failed to disengage upon pressing the button, which required the contact to turn off, restart, and drive the vehicle for some time for the brake auto hold to disengage. The contact stated that the failure had been recurring. The contact stated that the infotainment system was inoperable. Additionally, the passenger's side rear seat belt failed to buckle as intended, and the passenger's side rear door handle fractured while the contact was opening the door. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 102,000.

My 2017 Hyundai Tucson has completely broken down will not go into reverse had a diagnostics at Hyundai. I thought it was going to be covered because of the class action suit. My car apparently was not in the recall or the suit. I don’t understand I have the identical problem of the dual clutch transmission issue. I’ve tried to get Hyundai to do good-faith repair they refused. I’ve contacted carmax where I purchased the vehicle. They had the car when the lawsuit was finalized I didn’t know anything about the lawsuit or the problem with the vehicle. I’ve had the car for five years it’s at 85,000 miles. I don’t know what to do.

Got vehicle registration notice and recall notice was on the form regarding a possible electrical fire while parked or driving. I just got this car about 9 months ago, dmv is still showing nothing has been done.

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.

All warning lights illuminate and the dashboard showing the speedometer shuts off while driving as well as the heads up display. You have no idea how fast you are going or if you are have any warning lights.

My instrument cluster goes off/on intermittently causing a safety issue (I'm unable to see how fast I'm driving etc). The problem has happened to me everyday for the last 1. 5 weeks, however the dealer has had the car for a week now and claims they can't replicate the issue to get the code to order the part (I have filed a complaint with Hyundai). I want to go on record as this is not a recall with Hyundai yet, but I am aware it is a well known problem with 2025 Hyundai Tucson's according to a north America facebook page I belong to where we discuss various topics (positive and negative) regarding our cars.

Both horns needed to be replaced three times due to both stopped working and I listed the dates below. First time replacement: 4-6-24, second time replacement: 10-9-24, third time replacement: 1-16-25. Now on 9-26-25 both horns stopped worknig again, I checked the horn fuse and that is good. I now need to call the dealer to have both horns replaced for the fourth time. I also contacted Hyundai's national customer service to log a complaint as well. To me this is a safty issue since the horn is used to possible prevent an accident. I check the horns when I drive the car since they go bad so often and I have under 28,000 miles on the vehicle.

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 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.

Front passenger door will not open using the key fob. It has to be opened from the inside door handle. If there was an accident the door would not be able to open from the outside. This is a serious safety issue. There have been numerous issues with this problem. Hyundai should recall these vehicles for this safety issue.

Parked subject car in garage at approximately 11:15 am after turning off ventilation fan and cutting engine off, which displayed "off" at dash button. At approximately 7 pm (same day) went into garage to retrieve item and heard this loud noise similar to an electric clothes dryer running - wasn't dryer. As I got close to car, heard this same sound. Raised hood and could feel air movement . Checked engine oil - not warm. Backed car out of garage into driveway out of safety concern in case of fire. Will contact Hyundai motors to report this incident and for instructions what action I should take next. This is the first incident regarding my car"s electrical system. During the 3 hours driving that morning, I had no warning signs on dashboard or fan motor running after turning engine off. Had made 3 stops and engine start ups during that time.

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).

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 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.

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. 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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.
