2024 Hyundai Tucson Electrical System Problems

There has been an urgent safety recall with no fix for 4 months. I need the issue to be resolved so that my vehicle is no longer a safety hazard, but both the dealership I purchased it from and the manufacturer have stated that it's not a big deal.

The problem first appeared after I bought my car to the dealership to replace an amplifier. Since then, my car has been there twice and they have not been able to identify the problem. I’m going back-and-forth with the dealership and hyundai corporation. after numerous incidents with my other vehicles, I no longer trust this place to repair and at this time it’s a safety issue while I’m driving. I work in a school district in [XXX] when the kids are around I need my front and back up cameras to work. it’s a safety concern for me and I need your advice.

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.

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.

My wife was slowly pulling into a parking spot, when at about 10ft from curb the car suddenly accelerated faster than she even thought the car even was capable of (the AWD likely helped). It hopped the curb and hit a tree. She backed it up to the parking spot (it acted normally) and had it towed to dealer. In hindsight, the car had been having a progressive amount and frequency of delay in normal acceleration, sometimes having a pause of up to second or two from pedal input to car response. We asked the dealer to check the EDR (event data recorder). The tech first said he didn't even know what that was, then that he checked with all his fellow techs and they didn't know either, then the story changed to the model not having an EDR. We politely told him which page in the Hyundai manual he can find it, and he refused to look, as did his boss. Car was transferred to a body shop, and disposition was to total the vehicle. While the body shop was still evaluating the car, we contacted a second dealer, who said they don't have a reader. I inspected the floormats before the car was towed, as that was an initial suspect, but it was locked in and clearly there was no obstruction. She was wearing tennis shoes and doesn't recall ever having an instance of hitting the wrong pedal in any vehicle. She thinks she was only coasting, not even touching the brake yet.

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.

See attached document for complaint.

The contact owns a 2024 Hyundai Tucson. The contact stated while driving approximately 60 MPH, the vehicle stalled. The contact stated that before the vehicle stalled, there were several unknown warning lights illuminated before the instrument cluster went black. The contact pulled over and shifted to park(P) and was able to restart the vehicle after several attempts. The contact stated that the failure had occurred intermittently and at various speeds. The vehicle also occurred while stopped at a traffic signal. The contact had taken the vehicle to a local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 18,000.

The contact owns a 2024 Hyundai Tucson. The contact stated that while the vehicle was parked, the horn was inoperable. The vehicle was taken to the dealer where it was diagnosed that the horn needed to be replaced. The vehicle was repaired. The contact related the failure to TSB: 23-BE-008H (Horn Assembly); however, the VIN was not included in the TSB. The manufacturer was notified of the failure and a case was opened. The failure mileage was 68,412.

Both horns failed in less than 15k miles. Any time spent on the internet shows this is a known issue. Reporting as a safety problem as you will not know they are gone until you need them to warn another car or person and you have no sound. Luckily I was not speeding and paying attention but the kid who rode a bike in front of me when my horns failed - wondered right out. I stopped just short of them. Only resulting in them falling over when they finally saw me and freaked out/fell over. Horns are located extremely close to the ground and can only be accessed if you remove the entire front bumper and side trim. So this isn't an easy fix for most people when/if they go out.

the entire computer system shorted out throughout the entire car. It did not let me select above all of what it affected. The entire car malfunction due to the dealer not doing predelivery inspection. They have the vehicle and have not given me a written explanation or reports as to what happened to cause this. This vehicle was defective and dangerous and should not have been sold.

A service bulletin for windshields leaking into 2024 Santa Cruz and Tucson vehicles was issued on 11/02/23 from Hyundai, causing passenger side flooding.The length of time these models were exposed to or held water could pose these safety risks: 1 Corrosion of various mechanical and electrical parts from water entry for months that could cause safety risks at a later time. Ex. Certain Hyundai vehicles were recalled in 2006-2015 for fires originating from the ABS system due to liquid leaks and corrosion caused by failing seals and leaking water. The electric systems could short out, spark, and cause a fire, posing a risk even when the car was not in operation. 2 The possibility of the presence of invisible mold spores that grow quickly inside a closed car environment is a serious health risk for those who have a high allergy to mold, allergic asthma, COPD or other lung problems. 3 Some vehicles also experienced water entry from a firewall separation from the windshield. If the firewall is part of the unibody construction and protection for components and passengers, this is concerning. 4 Inadequate or improper repair instructions cause new owner concerns regarding the integrity of their vehicle. A. Hyundai only authorized dealers to “...insert sealant in the area that has been improperly sealed.” An auto water leak tech reported such windshield leaks require a glass company for repairs. The dealer reported around eight other vehicles have experienced the leakage at their shop. I know of no inspections by Hyundai or other service techs but is available. I did not know my car had water in the passenger side for the two months I had it. These models have been exposed to water entry from their manufacture date from this defect that somehow slipped through inspection and quality control. A Hyundai forum reported that some models experienced windshield leaks back in 2020. I am very concerned that this continues to be a cost cutting practice passed on to consumers.
