2024 Hyundai Tucson SEL Convenience Hybrid Recall:Hyundai Campaign 290/NHSTA 23V-187 (subsequent Tucson tow harness fire recalls) My vehicle was brought into an authorized Hyundai dealership to address the safety hazard associated with the accessory tow hitch wiring harness recall. The dealership resolved the immediate fire hazard by completely disconnecting and removing the functional trailer wiring harness from my vehicle. My physical repair invoice explicitly states: "repair complete-disconnected the positive connector and removed OEM harness from the vehicle, installing a dust cap." No replacement harness was installed. Because this physical removal occurred, Hyundai's internal corporate warranty system has offically marked the safety recall as "Closed" and completed for my VIN. However, the manufacturer has failed to provide a safe, functional remedy to restore the vehicle's advertised and purchased towing utility. When checking with Hyundai Customer Care, I am told the redesigned waterproof harness (Part #CWF61-AU100) cannot be ordered or allocated to my vehicle because the computer systems views the safety risk as resolved and the recall closed. I called Findlay Hyundai in St. George to see if they had the part number CWF61-AU100, he said he did not but Ontario had some & could get the part in a few days. The manufacturer's remedy is inadequate. By permanently removing a functional utility to satisfy a safety metric, without providing a safe, operating replacement part. Hyundai has effectively disabled the towing capabilities of my vehicle without offering a true remedy. I am requesting that NHSTA compel Hyundai to reopen or provide a distinct parts-allocation path for vehicles that had their wiring harness removed rather than replaced.

On XXX we were driving from [XXX] to [XXX]. Going through the [XXX] mountains on [XXX]. At an elevation of about 6,000 ft. temperature was about 85, speed about 55 mph the window in the back seat (behind the driver) imploded with a huge bang (sounded like a bomb went off). Glass was all over the back seat. I thought someone had shot at our car. I was with a retired CHP and he confirmed no bullets or rocks - this window just spontaneously exploded sending glass shards like shrapnel in the car! Besides the noise of the explosion, which could have caused the driver to veer off the road, if anyone had been in the back seat they could have been killed or seriously wounded from the flying shrapnel. In talking with other people, I found out NHTSA has an open engineering analysis (DP23001) investigation regarding this issue. This is very serious and should NOT be allowed to happen. Appears there is defective glass in some Hyundai Tucson's - not sure if the pressure of going over the mountains had anything to do with it or the design of the car but I'm leery of driving this car now! Thank you for your time and hopefully the manufacturer will correct this issue ASAP or before someone dies. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2024 Hyundai Tucson hybrid SEL with a genuine Hyundai trailer hitch & trailer wiring harness that were installed by a Hyundai dealer. My vehicle was included in Recall P90. As part of the recall, the dealer disconnected & removed the wiring harness because Hyundai did not have an approved replacement available. As a result of the recall, my trailer lights no longer function. I can no longer legally or safely tow my boat trailer because the trailer has no brake lights, turn signals, or running lights. Before the recall, the trailer wiring worked properly. I contacted Hyundai Customer Care & requested an approved replacement wiring solution at no cost. I explained that the recall removed a factory-approved, dealer installed towing function but did not provide a remedy that restores the vehicle's towing capability. Hyundai advised me that no replacement remedy is currently available & would not escalate my concern. I believe this is an unreasonable lack of remedy for a safety recall. The recall has left my vehicle unable to safely perform the towing function for which it was equipped. I am requesting that Hyundai provide an approved replacement trailer wiring solution that fully restores the original towing capability at no cost to owners. No repair date is given for this repair.

Anytime I put it it in hands-free control on the highway. Even on the small highway normal strip the car swings left and right. And also when I'm getting off from the highway hello, Francis smells so close and there's a small bump the back of the car is sliding most of the time.

My 2024 Hyundai Tucson hybrid has been returned to the dealership on 3/20/26 and 4/10/26 to replace failed rear shocks and are now scheduled for replacement on 4/27/26 under warranty. I was told by Matthews Hyundai dealership that the part may have been defective the first time but after having the shocks fail again it is clearly a defect in design. The bouncing and ride is dangerous. Rear shock failure is a major safety hazard because it severely compromises vehicle stability, drastically reducing control during braking, cornering, and emergency maneuvers. It leads to increased braking distances, excessive rear-end bouncing, poor handling, and accelerated wear on other suspension components, significantly increasing the risk of accidents. I do not want to have an accident due to a faulty part.

I am filing a complaint regarding a persistent and disruptive software feature in my leased 2024 Hyundai Tucson Hybrid. The vehicle has an integrated "Red Light Camera Warning" that plays an audible voice alert every time I approach or pass an intersection with a red light camera. Despite numerous attempts through the dealership and Hyundai corporate support, according to Hyundai, the alert is part of their Advanced Driver Assistance System (ADAS) and is considered a safety feature. However, this is not a safety feature, it is a ticket avoidance alert, and the frequent and repetitive alerts create a distraction from safe driving. Key safety concerns: The alert interrupts active phone calls, audio, and music playback at every flagged intersection, regardless of whether I am obeying traffic laws. This forces the driver’s attention away from the road to deal with the disruption or attempt to resume audio. The alert is often triggered in rapid succession when driving through urban areas with multiple camera-monitored intersections, increasing driver stress and reducing focus. Competing manufacturers (Toyota, Honda, Ford, etc.) allow drivers to disable this feature, but Hyundai claims they do not. There is video documentation showing that Hyundai vehicles are capable of disabling this feature via a simple toggle [XXX]. Hyundai’s unwillingness to offer this basic option infringes on the driver’s ability to maintain focus and control over their in-vehicle environment. I respectfully request that NHTSA investigate whether this alert poses a safety hazard due to distraction and urge Hyundai to provide an option for owners to permanently disable or mute it. Thank you for your attention to this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving, car suddenly slowed and would not accelerate as normal with accelerator depressed. A dashboard warning "check hybrid system" appeared and acceleration was unable to power car up hill. Driver forced to pull over on shoulder. After turning off and turning on vehicle, issue seemed to temporarily resolve itself. Dealer was unable to identify any faults in the car 3 days after this incident, and returned car to owner. A week later, the same issue occurred. Car would not accelerate after stop sign. When pressing accelerator, car coasted forward a a few mph. Turning off vehicle and turning on again resulted in normal performance resuming.

This car has an option buried deep in the digital menus to limit the speed the car can go. It is impossible to accidentally turn it on. But two times now, the car has set a limit significantly under the road speed limit. For example — the car set a limit of 30 mph in a 45 mph zone, or 20 mph in a 35 mph zone. The only fix is to find a safe place to pull off the road, stop the car and restart. That clears it. I’m lucky that I was not rammed from behind given my forced way-too-slow speed.

Defective operation of switch that controls shade panel on panoramic roof. A quick single rearward press should open the shade panel on the panoramic roof. Sometimes is does. More often than not a quick single press operates as a long-duration press and opens the shade panel *and* opens the panoramic roof. This was reported to the Hyundai mechanic at my initial warranty service and ignored. This issue was again reported to the Hyundai Service Manager at my second warranty visit and he successfully reproduced the issue during his own testing. Having the panoramic roof open unexpectedly may be a driving hazard, requiring the driver to respond to the unexpected circumstance, take their eyes off the road to reengage the control switch to be able to close the panoramic roof (what if it is inadvertently opened during a thunder shower, dust storm, or hail storm?)

While driving at a freeway speed of 70mph, my panoramic sunroof basically exploded raining glass everywhere. It sounded like a shotgun blast. There was zero indication of an outside object hitting it. The damage was so extensive it would have to have taken a fairly large object to cause this. It also seemed to have blown the glass outward, which indicates to me that there was some faulty component in the sunroof itself. I've read and watched other people who've had similar incidents

The Hyundai I just purchased was packaged with BOTH carpeted and rubber mats. Both were priced and charged separately on the Hyundai window sticker. The car cannot be bought without paying for both. It is well known that driving with rubber mats over carpet mats creates a serious safety hazard that will can lead to the mat slipping and the driver losing control over speed and braking. I contacted Hyundai to warn of the safety issue and request a refund for one of the mat types. They basically told me to get lost. I think a safety violation should be issued against Hyundai. I fear someone will get killed because they use both mats in the car since they paid for both.

The VESS in the 2024 Hyundai Tucson Hybrid MUST be modulated. It creates a nuisance and living in a Home Owners Association, I am looking at fines for creating a nuisance. THe Law requiring this calls for approx 50 Decibels. This horn is 90 Db. My City has an Ordinance that does not allow noises over 85 Db between 11 PM and 7 AM, and 9 AM on weekends. BECAUSE OF THE NOISE LEVEL WHEN BACKING UP, I AM UNABLE TO DRIVE THIS CAR. I have no choice but to park my car in my garage, thus backing up is mandatory. Also, in parking lots, it is embarrassing for my car to sound like a large garbage truck backing up. SOMETHING MUST BE DONE TO LESSEN THIS NOISE. MOST IMPORTANT, BECAUSE OF THIS NOISE, I AM FORCED TO RUSH MY BACKUPS, LIKELY NOT CONCENTRATING AS I SHOULD DUE TO THE BLARING EFECT OF 90 DB, AND CAUSING ME TO NOT CONCENTRATE AS WELL AS I SHOULD IF I BACK UP AT "NORMAL" SPEEDS. Also, each time I put the car in reverse, if there is an open window I get a warning on my smart watch that the noise level is dangerously high. ALL OTHERS OWNING THIS CAR ARE SIMILARLY AFFECTED. So in addition to it being illegal, this noise CREATES A GREATER DANGER than a reasonable noise level would create. I an upset with the dealership for not letting me know about that noise. WHen they demo'd the reverse aspect, they did so on a ICE model, not a Hybrid, so I had no way of knowing the unreasonable & illegal noise level. Had I known of this VESS noise, I would not have bought the car. I asked the dealer after owning the car few days what can be done, and they said they would do nothing and they would not allow me to return the car. HYUNDAI NEEDS TO PROVIDE A FIX FOR THIS UNTENABLE SITUATION! IF NO FIX IS IMMINENT THEY MUST ALLOW ME TO RETURN THE CAR WITHOUT A LOSS OF THE MONEY PAID. HYUNDAI NEEDS TO REMEDY THIS SITUATION ASAP!

The implementation of the hybrid car backup warning siren exceeds safe noise limits. In order to meet the fed reg requiring the vehicle to emit a sound that reaches the 56 db level 6 feet from the rear bumper- Hyundai installs a >90db speaker in the front of the car. This design decision saved money and meets the standard but at a tremendous cost to those who happen to be in front of the car when it's in reverse. This is big concern for those living in Apts and areas they have to park in close proximity to neighbors homes. In my 2-3 story complex, parking can be 5 feet from a bedroom window. Car owners do not have to right to determine when their neighbors sleep. The sound also travels well with the aid of concrete and brick disturbing dozens! Early or late arrivals can cause irate behavior in those awakened-- so yes this is a safety issue! Hyundai should be forced to recall and install a redesigned sound system for times the car is in EV mode. Honda and Toyota have a friendlier solution to meet this reg. BTW- it should also be required for OEMs to develop software that allows owners to turn off- all the beeps! For example, when a door opened or locked. Again the the beeps are loud and travel well. Flashing lights can be used instead of beeps.
