Repeat repair timeline – loss of acceleration vehicle: 2022 Hyundai Tucson hybrid blue issue: intermittent loss of acceleration from a complete stop (safety concern) occurrence 1 approx. Date: 12/2025 mileage: ~ 48000 description: vehicle failed to accelerate immediately after a complete stop. Pressed accelerator and experienced a noticeable delay before the vehicle moved. No warning lights. Turned on and off. Restarted normal. Action taken: no service visit at this time. Occurrence 2 approx. Date: 01/2025 mileage: 12/2025 description: same issue occurred again from a complete stop. Delay in acceleration while entering traffic. No dashboard warnings. Action taken: issue noted for future service visit. Occurrence 3 (reported to dealership) date: 50,000-mile service 01/14/2025 mileage: ~50,000 miles description: loss of acceleration from a stop occurred multiple times prior to this visit. I informed the dealership that this was a very dangerous safety issue. Dealership response: vehicle was serviced as part of the 50,000-mile maintenance. Dealership stated they could not find anything wrong. No specific repair or explanation provided. Outcome: issue was not resolved. Occurrence 4 (post-service) date: January 28, 2026 mileage: ~55,999 miles description: after coming to a complete stop, I pressed the accelerator and the vehicle did not respond for several seconds. No warning lights or alerts. This occurred after the dealership stated no issue was found. This condition has resulted in a dangerous delay while entering traffic and creates an immediate and ongoing safety risk to the myself and young children passengers, and surrounding vehicles. The defect involves a loss of acceleration / loss of motive power and has occurred repeatedly without warning. I am formally requesting escalation beyond the dealership level, full documentation of this safety defect, and a permanent corrective resolution. It is not safe.

Hyundai has deemed the horn to be defective and they state there are no replacements for them. This has caused me great concern to my safety as I am not able to alert other drivers of lane intrusion, parking lot back ups ect.

On January 25, I was driving on the freeway and my moonroof front panel exploded. It was a loud bang, and completely unexpected. This could have caused an accident. After the glass exploded, I pulled over only to realize the glass had hit another cars windshield and broke their windshield. I am lucky this didn’t cause an accident.

The situation I’m about to explain has happened twice—once in December 2025 and again on January 22, 2026. In December, the roads were very icy, but there was no snow on the ground. As I made a right turn into a walmart parking lot, I heard a loud metal-breaking sound while turning. I immediately got out and looked underneath my 2018 Hyundai Tucson sel but didn’t see anything unusual. After finishing my shopping, I started the SUV to pull out of the parking space. The car was trying to move, but the rear tires were not moving at all. A man waiting for my parking spot noticed this and told me one of the tires wasn’t turning. As I drove home, I heard extremely loud metal noises coming from the back of the vehicle—sounds like metal twisting, breaking, and falling to the ground. At no point did any warning lights come on. I took the car to a highly rated mechanic, premier car care, where they did a thorough inspection and found nothing wrong. After being reassured that the vehicle was safe, I continued driving it. Then on January 22, 2026, the same issue happened again. I was driving to my internship, and the roads were slushy. Suddenly, the Tucson became unstable, slid unexpectedly, and I heard the same metal twisting and breaking noises. This time, the abs light came on briefly and then went off. The vehicle felt unsafe and unstable, even though I was driving very slowly—around 15 miles per hour. I was terrified and nearly hit someone. I had the car towed through triple a back to the mechanic, but once again, they were unable to find the cause after inspecting it, and it is sitting in my driveway. I am reaching out because I am on disability, I have three children with autism, and I am also currently in school. I rely on this vehicle, and I truly need help investigating what is happening so this issue can be properly identified and fixed before someone gets seriously hurt.

The horn on my 2025 Hyundai Tucson limited failed without warning in mid January 2026 and no longer functions. This creates a serious safety risk because I was unable to warn another driver while they were merging into my lane on the highway. Without a functioning horn, I cannot alert other drivers to avoid potential collisions. The vehicle was inspected by balise Hyundai in springfield, MA, on January 23, 2026, and the dealership confirmed the horn requires replacement. However, they cannot cannot order the replacement part because it is unavailable, possibly due to a redesign or manufacturer change. Hyundai consumer affairs has acknowledged the defect and confirmed there is no timeline for repair. They are not allowing dealerships to order the old part and do not have a timeline on when the redesigned part will be available. Because the horn does not function, my massachusetts state inspection sticker is expired and cannot be renewed until the horn is repaired, making the vehicle illegal to operate. There were no warning lamps or prior symptoms before the failure. The vehicle is available for inspection upon request.

No visible speedometer as the dashboard was either blank or flashed message "no signal". The hud was not showing either. A vehicle unable to display the speed is inherently unsafe. This occurred with an overnight parked car. After about 20 minutes of driving, normal operation resumed.

At dusk I was driving below the speed limit (40 mph). I was at least 3 car lengths behind the vehicle in front of me when I saw the driver was braking because his brake lights came on and there was an intersection ahead with a stop light. There were at least two cars ahead of the vehicler I was behind. I braked but the car kept on going and appeared to accelerate. I was unable to stop the car with the brakes and collided with the car ahead. It was a sturdy vehicle with a strong bumper so I did not do much damage, if any, to the vehicle but my car requires $6,645. 90 of repairs. No one was hurt and the air bags did not deploy. I was wearing my seat belt. There was no warning from NY vehicle that I was getting too close to the vehicle ahead and my car made no attempt to brake automatically. It was as though all warning indicators were not functioning. I have had two other incidents of the car surging ahead but did not report it because no one else was involved and I was able to correct the speed and I thought it was just my imagination.

The contact owns a 2022 Hyundai Tucson. The contact stated that while driving at various speeds, the driver’s and passenger’s side turn signals were flashing quickly. No warning light was illuminated. The contact stated that the driver’s side and passenger’s side turn signals failed to properly illuminate. The vehicle was taken to a local dealer, where it was diagnosed with a short-circuited wiring harness, which caused the junction box to fail. The vehicle was not repaired. Upon further investigation, the contact stated that the part number: cwf61-au000; was installed previously by the same local dealer; however, the contact related the failure to NHTSA campaign: 25e091000 (trailer hitches). The manufacturer was made aware of the failure. The failure mileage was approximately 64,000.

While driving my speedometer became erratic, just one time. My cruise control is no longer working, my trip odometer is not working and possibly the odometer is not working properly. I googled for speedometer problems with 2011 Hyundai speedometers and found an article that may be false on reuters "Hyundai motor to recall nearly 84,000 us vehicles over instrument panel display failure, NHTSA says" I called Hyundai last week and the lady I spoke with said there was a service bulletin and said it would be repaired at no cost! she even set me up with an appointment at the local dealer. About 2 days later I received an email that said there was no TSB and that it was not covered under warranty. I cancelled the appointment and stopped at the Hyundai dealership. The man I spoke with seemed to know exactly what I was talking about and said it would be almost $200 to diagnose and that would be applied to the repair which would be $7-800. He also said there are 2 different switches and it coud be either switch. I know there's a lot of garbage on the internet but when I saw the article that said that "NHTSA says" and then was told by someone at Hyundai that there is a service bulletin, I believed it. I'm [xxx] old and my wife and I have had this vehicle since new. It's a good vehicle and most likely our last. However I am totally bewildered by this situation. Is there a recall/service bulletin that you are aware of or not? thank you! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Rear door automatically opens randomly. This feature is configured to be disabled through the onboard settings.

Sun roof on Tucson 2023 shattered while car was being driven. When the roof shattered there was a loud sound (like a bomb going off) in the car and then the sound of glass breaking. The vehicle is available for inspection. There were not any warnings or messages before the failure. Safety was at risk for the passengers and any vehicles that were following. The loud sound caused the driver to swerve and could have caused an accident if another vehicle was on either side of the car. The vehicle was taken to a dealership and shown the damage and the service advisor stated he never heard of a problem. I have contacted Hyundai and they said it might take 6 to 8 weeks before an inspection could be made. There are many messages on the web from people with the same issues. Hyundai did a recall for this same issue for earlier production dates.

During normal winter operation with the heater in use, the center console area becomes excessively hot. I have measured surface temperatures exceeding approximately 130°f using an infrared thermometer. The affected area includes interior touch surfaces, cup holders, and a factory-installed wireless phone charging pad. The heat appears to originate from hvac ducting routed through the center console to supply the rear seat vents. Closing the rear vents does not reduce the console temperature, indicating heat transfer through the ducting rather than airflow. The condition is most severe after a warm-soak cycle (driving to operating temperature, briefly parking, then driving again). When a phone is placed in the intended storage or wireless charging area, the device overheats and triggers thermal protection warnings. The console surfaces also become hot enough to present a potential burn risk with prolonged skin contact. These temperatures exceed recommended ambient conditions for consumer electronics and lithium-ion batteries in a normal-use interior storage and charging location. The issue was reported to a Hyundai dealership. The service department stated the heat was caused by the rear hvac duct and considered the condition “normal. ” no repair, insulation review, or corrective action was offered, and no specific temperature measurements were provided in writing. Hyundai consumer affairs directed me to return to the same service department, despite the concern remaining unresolved. This condition occurs during normal vehicle operation and represents a potential interior thermal safety concern.

Horn did not work. At about 67,000 miles on my vehicle my horn stopped working. I took it to the dealership to be replaced and paid for it. Then again at about 100,000 miles it stopped working. I took it back to the dealership and asked if there’s been any recalls they stated not at this time but there’s been a lot of people complaining about their horns and they told me to save my receipt receipts because I might be able to get reimbursed later. On two different occasions. I’ve been driving and had a car changing lanes into my lane and when I went to honk the horn to alert them, it didn’t work. Now I’m also concerned that I’ve got the same horn put on my vehicle for a third time and that I’m going to have to go back in and pay for a third one. I did reach out to Hyundai USA first and ask them to make this right but they stated they do not have an extended warranty for the 2023 vehicles even though they do have bills for 2020 through 2022. I can get copies of the receipts if they’re needed.

High oil consumption.

Multiple times the car has locked the brakes when there was a car several car lengths in front of me. This has resulted in me nearly being rear ended three different times. The force of the stop has also caused me to have neck and back pain. This is u safe and will result in injuries. There are many reports about this on reddit.

Two times while stopped or idling behind a car in traffic, my Hyundai Tucson 2023 has started accelerating on its own with the rpm increasing to nearly 8000 and lurching forward before I was able to apply brakes. Stop the car and restart. I have seen this described on other car message boards and hope the NHTSA will take this seriously. The dealership is not being helpful and claims they cannot reproduce it and it has not caused any onboard diagnostic codes.

Drove into a parking space, with the foot pressing on the brake pedal, the car suddenly and without warning rapidly accelerated uncontrolled causing the vehicle to accelerate past the end of the parking space causing property damage.

The dashboard and heads up display intermittently goes on and off. All warning lights are on when the dashboard comes back on. It goes off long enough to not know how fast you are going. Hyundai has this as a known issue for limited trims of the Hyundai Tucson yet they only tell you to take it to the dealer for the vehicle to be fixed. Customers have taken their vehicle back to the dealership after the dealerships stated that the issue was fixed because the issue happens again a few days later. This is a safety issue that needs to be addressed.

Rear subframe corrosion.

After inspection by a few people it was determined that the front passenger side lower frame cracked which then cracked the body oozing rusty water out of it. I was told that if the car was hit on the passenger side that it would not retain its ability to be stable and would crumple. It has been inspected by the Hyundai dealership, a general manager from another dealership and 3 auto body welders. This first appeared in December of 2025 after I had washed my car and was drying it off.

Horn stopped before odometer hit 6,000 miles, dealer was unfamiliar with problem until I googled it and found out Hyundai is having horn issues, then they were aware of problem. Took 34 days to get this issue repaired.

I purchased the 2025 Hyundai tuscon limited in October this year. My conern is the headlights. When driving at night using the normal headlights, on the road on the left side shining there appears to be a black spot ahead of me. I've had asked front seat passenger if they noted it also to which they affirmed. I did asked my Hyundai dealer about this and they stated that it is intended that way so that the oncoming vehicle is not blinded by my headlights. I'm driving on a 4 lane divide highway and it is very disracting to me as I feel I cannot see anything on the left side of the left lane when I am in the right lane. This is very distracting and they informed that it's that way on all of thier moderls.

I was rear-ended at an extremely high speed by an intoxicated driver. The impact from being rear-ended pushed my vehicle into another car, damaging the front and rear of my vehicle. My car was a 2024 Tucson with 14,646 miles in perfect condition. No warning lights were on the vehicle, as I consistently take excellent care of my cars. The airbags did not deploy. My car was totaled. I had several injuries from the accident.

My 2023 Hyundai Tucson’s windshield has developed excessive pitting, multiple chips, and cracks despite only normal highway driving. I do not drive on gravel or dirt roads, yet the glass shows abnormal wear far beyond what would be expected for a vehicle this new. One of the larger chips was repaired by safelite, and during the repair the windshield cracked further, suggesting the glass is unusually weak or defective. Visibility has become noticeably compromised due to the fine pitting across the entire windshield. Based on the number of similar complaints from other Tucson owners, this appears to be a recurring safety issue with Hyundai windshields.

While operating the vehicle, an intermittent audible warning sound occurs without any corresponding alert, message, or notification displayed on the dashboard or infotainment screen. The specific component or system causing the warning is unknown. The vehicle is available for inspection upon request. This condition puts my safety at risk because the unexplained warning sound occurs while driving and causes me to divert my attention from the road in an attempt to identify the source or meaning of the alert, creating a driver distraction. The issue has been reproduced multiple times under normal driving conditions. I demonstrated the condition to the dealership and provided video evidence; however, the issue has not been diagnosed or confirmed, and no root cause has been identified. The vehicle has been inspected by the dealership, but no explanation or resolution has been provided. The manufacturer is aware of the issue through an open case. There were no warning lamps, messages, or prior indicators associated with this condition. The audible warning occurs without any visible alert or explanation. The condition began shortly after purchase in November 2025 and was later documented and demonstrated to the dealership in January 2026.

(NHTSA tracking number 11726105) I am updating my existing complaint regarding my 2024 Hyundai Tucson (NHTSA tracking number 11726105) for an ongoing safety concern involving an intermittent warning chime while driving. This issue began shortly after I purchased the vehicle in Nov 2025 and has been reported to the dealership multiple times over several months. The warning chime occurs randomly while driving without any visible warning message or dashboard alert. This creates uncertainty because I do not know what the vehicle is trying to warn me about, which is distracting and creates a safety concern while driving. The dealership previously replaced both front seatbelt buckle assemblies after identifying intermittent high resistance as a possible cause. However, after that repair was completed, the warning chime occurred again while I was driving to the dealership for a follow-up visit. This confirmed that the issue was not fully resolved. I immediately returned the vehicle to the dealership, and they are now performing further diagnosis. I was advised that if the issue reoccurred, the next possible areas for diagnosis could involve the instrument cluster or the control module, both of which are safety-related systems connected to warning alerts and seatbelt functions. In addition, during this same visit, the dealership confirmed there is an actual oil leak requiring repair. This is significant because when I first raised this concern after an outside inspection in December 2025, I was told it was likely leftover residue from a prior oil change. The dealership has now confirmed it is a real leak and kept the vehicle for repair while providing a loaner vehicle. Because this vehicle was sold as certified pre-owned and these safety and mechanical concerns continue shortly after purchase, I remain concerned about the reliability and safety of the vehicle.

The front end collision avoidance “feature” slammed on my brakes so hard today, for zero reason. I was already braking, going less than 20mph and had plenty of room. This is not the first time, closer to double digits since I purchase in April. This time the car behind me narrowly avoided hitting me which was made worse as my vehicle takes too long to unlock and allow me to begin driving again. This is going to cause an accident and ruin my tires/brakes costing me money.

I had to retrieve something from the back of my Hyundai Tucson hybrid SUV, opened the back door. I retrieved several items and placed them in a safe area. Got back into my vehicle and proceeded to drive into my garage (with the rear door fully open). Next thing I heard was my Tucson crashing into my garage door. I had no warnings, flashing lights or audio sounds nothing that would help me avoid that collision. The reason I purchased this particular vehicle was because it comes with sensors and cameras completely around the vehicle (including the rear). In fact on the rear door is sensor and a camera. In fact I can park the Tucson out of the vehicle. The sensors will ensure that it will not collide with anything. Same is true in a very tight parking spot. Anyway the other 4 passenger doors have several warning signals. From low ibeeping to very loud annoying audio sounds that you cannot ignore. I’ve contacted Hyundai motor America and they’ve denied my complaint. They claim that the extent of the “warning is a red light on the dash”. My local dealership kept my Tucson for 11 days not knowing what to do and how to resolve this problem. I’ve come to reply on the audio warning system, and as a senior citizen, not to look at the dash to prevent collisions. This is very serious ,especially, if that door is not locked while I’m driving, any thing can push open the door, resulting in injury or death to people in the vehicle or on the road. This is compounded by the fact that Hyundai produces many types of suvs, including genesis.

I started the car and put it in gear and it would not move. Then the check hybrid system and transmission warning showed up. This happened two times and I had to have the car towed in. The second time, it was determined that it is related to a recent recall for the oil pump unit opu software. This recall is not listed any where and drivers are not being informed of it. Hyundai is not responding to my complaint.

Bought car end of April brand new. June 25 brought in, console display went blank. Tried to start my car 11/10 and it would not recognize the key. Had to have it towed to dealership. Car battery was not dead, fob could start car, open doors, etc, but the car shut off as soon as you tried to start the car inside. Originally told fob problem. Nope. The told security control. Nope. Now being told it’s the bdc, basically the “control brain” of the car. Part is back ordered and my car is sitting parked at the dealership. It’s useless. Did some research and found that the bdc is becoming more and more common with a lot of people that have this car. It’s only 7 months old. No warning, dealer knows it won’t recognize fobs and not a fob problem. I was told, that the screen going blank in June was connected to this.

Component that fails & available for inspection upon request? hvac heat exchange and faulty gas gauge. I drive from minneapolis to warroad, mn frequently and the floor wells has insufficient heat hence impairing use and safety in minnesota's severe climate. I have videos on the following but I am unable to upload videos to your site: (1) when I have heat on high, full blast and to foot well only, the dashboard vent is 115-143 degrees (using a digital food thermometer) and a ~60 degree difference with the footwell at 65-85 (although 85 degrees sounds warm at 1 degree outside my feet are very cold - I would be happy to have you test this with me). (2) brand new SUV consistently 1. 5 - 3 hrs to warm up. I explained to Hyundai this is not a software issue rather an hvac air exchange issue. (3) the gas gauge consistently underestimates the remaining fuel available by 50% in cold weather - an issue that between bemidji, mn and baudette, mn (102 miles/1hr 45min) there are few gas stations. On 11/11/2025 I took the SUV to first bloomington Hyundai - they said it is working as designed. Then 11/20/2025 to morries Hyundai said they are aware of a similar situation with the eon. However, without an "error code" Hyundai is unwilling to fix the air exchange. Additionally, I opened case#: xxx[xxx] -68 with Hyundai corporate - additionally they are unwilling to admit fault - this vehicle should not be sold in minnesota's extreme climate conditions. How was your safety of others put at risk? if I run out of gas, my passengers and I risk frost bite or fatality of hypothermia. Has the problem been reproduced or confirmed by a dealer service center? yes. Has the vehicle or component been inspected by the manufacturer? yes. Were there any warning messages or other symptoms of the problem prior to the failure, and when did they first appear? no warning messages have ever appeared. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was 15 minutes into my commute home on route 9 in massachusetts when I stopped at a red light. When I took my foot off the brake and stepped on the gas the car would not accelerate more than 5 miles an hour. I was stuck in the intersection for about 10 minutes and had to put on my hazards and get into the right lane and keep driving at 5 mph until I found a place to pull over and restart the car. When I restarted it it drove ok.

My adult son was driving and under the hood started to smoke. He pulled over and opened the hood to take a look and then a fire started under the hood! the fire department was called and they put out the fire, cut the gasoline and duct taped it up so the fuel line would not further ignite the hot engine. My insurance is looking into what would have caused a random under the hood fire. Luckily no one was injured. However the engine section of the car is melted beyond belief. My insurance has not told me if the car is repairable or not.
