2024 Hyundai Tucson electrical problems

the federal safety agency VEHICLE SAFETY COMPLAINT Vehicle Information: * Year: 2024 * Make: Hyundai * Model: Tucson * VIN: [XXX] * Mileage: Approximately 65,000 * Dealership: Hyundai of [XXX] Complaint Description: I am filing this formal safety complaint regarding my 2024 Hyundai Tucson, which is experiencing recurring water intrusion and electrical malfunctions. Every time it rains, water enters the interior of my vehicle, causing flooding. This is not an isolated incident. The flooding occurs repeatedly during rainfall, and I am extremely concerned that there may be an underlying manufacturing, assembly, sealing, or drainage defect. In addition to the flooding, my vehicle’s electronic systems have begun malfunctioning. My radio operates on its own without my input, my touchscreen becomes unresponsive, and the buttons do not function when needed. I am concerned that water may be reaching electrical components and contributing to these malfunctions, although the exact cause has not been determined. I have not been involved in an accident or caused any known damage to the vehicle that would explain the recurring water intrusion. I reported my concerns to Hyundai of Orange Park in [XXX]. However, I was informed that because my vehicle is outside its warranty coverage, I would be responsible for the diagnostic and repair expenses. When I escalated my concerns to a Hyundai supervisor, I was presented with two options: pay thousands of dollars to have the vehicle disassembled to investigate the problem or purchase another vehicle. My concerns about the possible safety implications of the flooding and electrical malfunctions remain unresolved. I am particularly worried about moisture-related electrical failures, corrosion, and the possibility that additional vehicle systems could malfunction. I am concerned about the safety of myself, my passengers, and others on the road. This vehicle is a 2024 model with approximately 6 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was notified about a recall for the tow hitch wiring harness. I took it to the dealer to have it repaired. Instead of repairing it, they just removed the wiring harness from the vehicle. When I asked them when the actual repair would be completed they said they had no idea. The service manager at the Hyundai dealership told me that some of his customers were mad about not having a safe and working tow hitch package that they had paid for, after they removed the wiring harness, that they were taking their cars to U-Haul dealers to have tow hitch wiring harnesses installed. He also told me to call the Hyundai customer service hotline which I did. The hotline told me that they could not even tell me if they were even working on a permanent repair for my car. The recall for my car now states "COMPLETED", which is totally wrong. They simply removed the wiring harness, without doing any actual repairs, leaving the tow system completely inoperable and VERY unsafe to use. I am now left with a car that is now unsafe when towing a trailer due to it no longer having a wiring harness installed for it, so I now have no trailer lights.

I have a 2024 Hyundai Tuscon SLE that I purchased new and several months ago there was a recall on the trailer hitch wiring. I took the car to Hyundai and they removed the wiring harness hitch due to a fire danager. Todate I have not received a replacement hiring harness, so my vehicle is now useless for pulling a trailer for several months. (The spring and summer months are when I use this the most and have not been able to.) All I hear from Hyundai is that they do not have a cure for this. I notice that the 2025 and 2026 models have a wiring harness on them that do not need replacing. I need something done ASAP regarding this matter. Why has NOTHING been done regarding this replacement? It has been MUCH TOO LONG! Is there ANYONE at your organization that can help me with this matter ASAP!!!! Thank you.

The air conditioning system in my 2024 Hyundai Tucson has never adequately cooled the cabin during high outdoor temperatures, since I purchased the vehicle. The vehicle is parked outdoors in direct sunlight daily, as I have no garage or carport access, and the issue is most severe and consistent during hot weather. This creates a heat exposure risk while driving, particularly on hot days when cabin temperatures remain uncomfortably high despite the AC running and set to the coldest setting. Prolonged exposure to excessive cabin heat can pose a safety risk, including impaired driver alertness and general heat-related discomfort/health risk. I brought the vehicle to CMA's Hyundai of Lynchburg on July 9, 2025 to report this issue; the dealership found no fault and stated the AC was working correctly. I brought the vehicle in again on August 11, 2026 with the same complaint; the dealership again reported the AC was blowing air at the correct temperature, with no fault identified. The vehicle has been inspected and is available for further inspection upon request. There were no dashboard warning lights or messages associated with this issue. The problem has been consistent since I've owned the vehicle, and is worse specifically in hot weather.

On 7/29/2026, the vehicle experienced a critical safety failure involving the electronic transmission shift-by-wire system, resulting in an unintended rollaway after the ignition was turned off. While parked on an incline, the driver depressed the brake pedal and pressed the Engine Start/Stop button while the vehicle was still positioned in Drive (D). The engine shut off completely. According to factory safety design and vehicle specifications, cutting the ignition in this state is engineered to automatically trigger an electronic command to shift the transmission into Park (P). However, the vehicle failed to execute this electronic fail-safe. The electronic parking pawl did not engage, and the vehicle effectively defaulted into an un-geared Neutral state. Upon the driver releasing the brake pedal, the unanchored vehicle immediately rolled down the incline with the engine completely powered off. No audible warning chimes or dashboard fault lights were activated prior to or during the event to alert the driver that the transmission had failed to secure the vehicle.

(the federal safety agency Tracking Number 11726105) I am updating my existing complaint regarding my 2024 Hyundai Tucson (the federal safety agency 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.

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.

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.

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.
