While driving my 2024 Hyundai Tucson at highway speeds on a clear day with no surrounding traffic, I was startled by an extremely loud bang that sounded like an explosion. Pieces of shattered glass rained down inside the passenger cabin, creating a potentially hazardous situation. This incident was a traumatic experience. The sudden and unexpected event had the potential to cause serious injury to the driver, as well as increase the risk of a collision due to the shock and distraction it caused. Additionally, other pieces of shattered glass were propelled from the vehicle, posing a risk of injury or damage to other drivers on the road. Upon physical inspection, it was noted that the glass from the panoramic sunroof was bowed upwards, which suggests the explosion originated from within the sunroof and NOT an external factor such as road debris or a rock. The vehicle, which is less than a year old, is currently at the Hyundai dealership pending an investigation. Given the severity of the incident and the potential risks to driver and passenger safety, I strongly recommend that a recall be issued or a comprehensive investigation be initiated by the NHTSA to prevent further occurrences of such dangerous incidents. Safety must be a priority, and swift action is necessary to ensure that no other drivers or passengers are at risk of similar events.

Horns failing after being replaced by Hyundai. A kid was running and heading on a path in front of the SUV. Pushed the horn and another failure. Luckily the brakes work - the kid didn't stop. First attempt to fix: 14,612 miles - current miles at 2nd failure 17463.

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.

I had the windshield recall repaired and my car still leaked. It has been at the dealership for over 2 weeks for repair. I am concerned whether this vehicle will be safe to drive even after a new windshield is in stalled and all of the carpeting has been replaced. The vehicle is only 8 months old from the time I purchased it from the Hyundia Dealership

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* 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

While driving my vehicle (fewer than 3,000 miles on it) I pulled out of a parking lot onto a busy street. The car suddenly stopped driving, slowing to a complete stop. The dashboard read "Auto start stop reset required." I had to place the car in park (on the busy road) and press the start button to resume driving. Temperature gauge read normal, gas was full, no oddities showing on my dash board.

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.

-??What component or system failed or malfunctioned, and is it available for inspection upon request" I am not sure exactly what system was involved. But I was pulling in to a parking space on a Washington DC street on Saturday [XXX] when my car suddenly accelerated the steering locked, the brakes didn-??t respond and the vehicle mounted a curb and struck a tree. -??How was your safety or the safety of others put at risk? The car went out of my control for a few moments, making it impossible to steer or brake. My wife and I were slightly injured when the car struck the tree and if the tree wasn-??t there it could have continued on the sidewalk and struck a pedestrian or of the houses beyond the tree. -??Has the problem been reproduced or confirmed by a dealer or independent service center? No. I reported it to the dealer the day it happened. They said I needed to take it to their service department to be looked at. The facility is closed on weekends -?" and I will take it in for inspection today, [XXX]. -??Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, it has not. -??Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No, there was no warning that indicated there was a problem. After the incident, the car reported the front passenger side parking camera was obscured or broken (this was from the impact with the tree).

The heating system doesn-??t work - have yo run at settings well over 80 yo get a modicum of warmth. Each time I took in, they-??d give me a loaner and each loaner had same issue. Hyundai corporate claims that-??s how it should be. Alerts keep resetting to off when car is turned off. That way since I bought car and never fixed

The forward collision avoidance system made me have accident. I was driving on the expressway, the forward collision made the car stop abruptly, then accelerate. As I was veering to the right, the car stopped again in the middle of the expressway causing me to have an accident. This is unacceptable and very unsafe. This vehicle is not safe to drive with the collision warnings.

The vehicle continues to leak water into the floor carpet even after a recall was supposed to fix the windshield leak problem for this car. This can cause mold.

- Hollister , CA, USA

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.

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.

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.
