Hyundai Tucson electrical problems

I am writing regarding the diagnosis provided for my vehicle [XXX] . I was informed today that the engine failure is being attributed to a "water hose failure" rather than the engine defects covered under the active safety recall/settlement regarding Connecting Rod Bearing failure. As there were no coolant leaks before or after the vehicle was towed to your dealership. I am formally requesting a re-evaluation and more detailed evidence. Given the known history of these engines seizing, I need to ensure this diagnosis is absolutely correct and not a symptom of the internal defect. I request the following information be provided immediately: 1. Evidence of Overheating: Did the vehicle store any specific "overheating" codes in the ECU prior to the engine shutting off? 2. Oil Pan Inspection: Has the oil pan been removed to inspect for metal shavings or debris? If the connecting rod bearings failed (the recall issue), there will likely be metallic debris in the oil, regardless of the condition of the water hose. 3. Bearing Clearance Test (BCT): Was the mandated Bearing Clearance Test performed? If not, I request that this be done, or that a teardown be performed to inspect the rod bearings specifically. 4. Causal Link: Can you provide evidence that the water hose failed causing the engine to seize, rather than the engine seizing causing a pressure spike that damaged the cooling system? I have no transportation to work and school. They would not honor a loaner. This has happened since Decemeber of 2025. I await your written response with the requested photos and technical data. My case # with Hyundai Consumer Affairs # XXX Please provide: All relevant photographs Freeze-frame and ECU data Technician diagnostic notes Results of oil pan inspection and/or BCT (if performed) Any physical evidence supporting the stated cause of failure I request this information be sent in writing at your earliest convenience.

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.

On March 13, 2026, I was operating my 2015 Hyundai Tucson when the steering locked up, causing me to crash into a tree head-on. In the course of this head-on crash, my airbags failed to deploy. As a direct result of my airbags not deploying in a serious car crash, my head hit the steering wheel, causing a confirmed concussion diagnosis of Post Traumatic Headache and Post Concussion Syndrome in a hospital emergency room. There were no lights or symbols on the dashboard prior to the accident. My car had a prior repair for a front end collision in a body shop and a replacement of the engine in a Hyundai dealership prior to the accident. My car is currently in a tow yard. There has been no inspection of my car by the manufacturer. I have since discovered that there are a number of complaints filed with the National Highway Traffic Safety Administration ("NHTSA") from other Hyundai Tucson owners for the model years 2005, 2006, 2007, 2012, 2013, 2019, and 2023 complaining of the same defect in their Hyundai Tucsons – the failure of the airbags to deploy in serious car accidents. I believe this represents a systemic safety defect in the Hyundai Tucson airbag system that has not been addressed for the 2015 model year. This failure put my safety at serious risk and resulted in significant injuries that could have been prevented had the airbag system functioned as designed.

I’d like to file a complaint regarding Hyundai Recall#290, a potential fire hazard with my cars “trailer wiring harness accessory module”, which Hyundai has not offered a remedy at this time. I spoke to Hyundai’s customer service representative yesterday (3/18/26) about this recall that’s now over a month old, and asked if I could get reimbursed for my out of pocket costs to remove the hitch’s wiring at a Hyundai dealership. The rep said Hyundai won’t pay for my out of pocket cost to remove the harness wiring because they don’t have an official “remedy” yet. My local Hyundai dealership said the cost to unplug/remove the wiring would be about $200, which in my opinion would solve the problem and certainly is a “remedy”. Hyundai refuses to reimburse me this cost even though they have a Hyundai recall reimbursement program for out of pocket expenses due to recall issues. My complaint: 1 - Hyundai has failed to provide a no cost recall remedy within a reasonable period of time. 2 - if I choose to pay for removal of the wiring, my out of pocket cost of $200 will not be reimbursed by Hyundai. 3 - Hyundai’s recall says I could continue to drive my 2024 Hyundai Tucson, but apparently if the car gets wet, the wiring could ignite and cause a fire, which I’m not very comfortable with. 4 - I don’t use the trailer harness module at all since I bought the car used from the original owner, so removing the entire harness would be a reasonable solution and allay the fire risk. Thank you.

After 3 months and 840 miles, my 2026 Hyundai Tucson wouldn't respond one morning. No power at all, including to unlock the car. Road side assistance struggled to jump out but finally the car started, but the cluster panel would not turn on. I had to drive to the dealership with no speedometer or other screen sensors, as well as a lack of blinker or lights. This is outrageous because I barely drive the car and it's brand new.

Wife was driving car and the steering locked up and she could not turn it for about 5 seconds. second issue was put it in reverse and it would not come out of reverse, she had to turn car off and on 3 times to get it to put it in park or drive. I ran this through my Claude AI and it says this is an ongoing problem with the Hyundai Tucson. Please make them fix this before selling anymore vehicles as both are major safety hazards.

Bought new, less that 400 miles in November 2025. Within 2 weeks dash board went blank/black. I consider this a driving distraction especially at night when nothing shows, no speed no gauges. Blackout time varies each occasion. Sometimes after a few seconds all warning light come on and stay on until vehicle shut off . Sometimes a NO GIGNAL message. Contiued after service visit with update to vehicle at about 7300 miles in January 2026. Service department acted like they have never heard of this issue.

The touchscreen is not reposnive to touch except in one tiny corner. We’re reported this at thw Hyundai dealership at least three times over the years- they said “they can’t see a problem”, which is odd because the screen literally does not respond to touch. When it’s hot, even with the AC on full blast, sometimes we will be driving and the touchscreen starts making beeps and starts going into the settings menu all on its own without being touched, and starts randomly changing settings. Or, we will connect a phone with google maps, and the screen will randomly change to something else or a different view. This is a dangerous distraction, and Hyundai has refused to acknowledge this problem. The screen is unusable, we are forced to use our phones to use navigation directions just to be safe in our own car. This has been an issue starting in 2023 and to this day has been persistent. We have done both hard and soft resets to ni avail. We have also reported, on going to the dealership, that the screen says to update- they have never provided any update or instructions on how to update, even though every time we go to the hyundai maintenance we are there for at least two hours or more.

The contact owns a 2019 Hyundai Tucson. The contact stated that upon entering the vehicle, there was water overflowing from the front passenger's side floormat. The vehicle was taken to the dealer, but the water entry point could not be determined. Additionally, the contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, where a brake sensor was replaced; however, the failure recurred. The vehicle was taken back to the dealer, where another brake sensor was replaced; however, the failure persisted. The vehicle was taken to the dealer, who diagnosed that the wiring harness had sustained water damage and corrosion due to a clogged sunroof drain. The dealer determined that the wiring harness needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the repair should be covered by the manufacturer because the failure was a factory defect. The manufacturer was not contacted. The failure mileage was approximately 30,000.

I am submitting this complaint regarding Hyundai Safety Recall #290 (NHTSA Recall No. 25V893) as it applies to my vehicle, VIN [XXX] . I received the official recall notice by mail on February 13, 2026. The recall identifies a defect involving the tow hitch wiring harness control module, which may allow water intrusion. According to the recall documentation, this defect can cause inoperative stop lamps and, in rare cases, an electrical short that could result in overheating or a vehicle fire. Since receiving the notice, I have contacted Hyundai Motor America corporate customer care three separate times seeking escalation and guidance on how to safely address this recall. During each call, Hyundai stated that no repair solution, parts availability, or timeline exists for remedying the defect. Despite the recall involving a documented fire risk and potential brake/stop lamp failure, Hyundai representatives advised me that I could continue driving the vehicle while waiting indefinitely for a remedy. No interim safety measures, inspections, alternative repairs, or mitigation steps were offered. I am concerned that Hyundai is failing to properly execute a federally mandated safety recall and is placing consumers in the position of operating vehicles with known, unresolved safety defects. Being advised to continue driving under these circumstances creates a risk to vehicle occupants and to other motorists. I am requesting that NHTSA review Hyundai’s handling of Recall #290, specifically regarding recall remedy delays, lack of escalation, and failure to mitigate an acknowledged safety risk, and take any enforcement or compliance action deemed appropriate.
