2024 Hyundai Tucson Hybrid

On Monday, 09/14/2026 at approximately 10:15am Mountain Time Utah State Route 36, North-bound. -- I was driving straight, approximately 60mph on dry road on a sunny day. There was no other traffic on the road either ahead, alongside, or behind me and no oncomming traffic. The Automatic Emergency Braking engaged, the emergency braking indicator flashed on the dashboard and the car slowed way down and then it just stopped engaging and the car rolled freely. I believe that the forward collision warning also sounded. NOTE-- this is not the first time this has happened to me. It has happened at least 3 to 4 times over the past two years since we leased the vehicle. I have asked the dealership service department to look at it, but they state that they can find no indication of any problem and that they have been unable to reproduce the event.

The contact owns a 2024 Hyundai Tucson. The contact stated that while operating the vehicle, the horn pad was pressed; however, the sound coming from the horn was extremely low. The vehicle was not yet repaired. The local dealer was notified of the failure, and an appointment was scheduled for the repair. The contact stated that the horn had been replaced twice for the same failure. The manufacturer was notified of the failure. The failure mileage was 12,907.

I was driving at a low speed (10-15mph) with a safe distance between me and the vehicle in front of me when the semi truck in front came to an abrupt stop. I reacted appropriately by pressing on the brake, however, my car accelerated into the vehicle instead. None of the emergency brake systems activated including the automatic emergency braking and front collision warning, which lead to my car driving into the semi-truck.

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

The contact owns a 2024 Hyundai Tucson. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V893000 (Trailer Hitches); and the contact became aware that there was no wiring harness on the vehicle after recall repair. The dealer informed the contact that removing the wiring harness and installing a dust cap was included in the recall remedy as provided by the manufacturer. The contact stated that the vehicle was not safe to haul a trailer because the brake lights and turn signals would be inoperable. The manufacturer was made aware of the failure. The failure mileage was approximately 22,000.

The contact owns a 2024 Hyundai Tucson. The contact received notification of NHTSA Campaign Number: 25V893000 (Trailer Hitches). The vehicle was taken to the dealer, where the contact was informed that the recall remedy consisted of removing the trailer hitch wiring harness. The contact declined the repair because the vehicle had been purchased specifically for the towing capability. The contact stated that the manufacturer had failed to provide an adequate fix under the recall. The manufacturer was notified of the issue and confirmed the information provided by the dealer. The contact had not experienced a failure.

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.

The contact owns a 2024 Hyundai Tucson. The contact stated that on three occasions while driving at 65 MPH, the automatic emergency braking system engaged erroneously. While driving at 45 MPH, the failure recurred, but the vehicle resumed normal operation. The automatic emergency braking message illuminated on the instrument panel. The contact related the failure to NHTSA Campaign Number: 26V316000 (Forward Collision Avoidance). The vehicle was taken to the dealer, but the dealer was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified, a case was opened, and the contact was informed that the dealer would have to duplicate the failure for repair coverage. The failure mileage was approximately 5,000.

6/16/26 on the 101 freeway for over an hour at 65 to 70mph. Emergency braking system engaged and warning appeared. Disappeared after about 3-5 seconds. June 30, 2026, again after driving for over an hour. No cars near, happens multiple times at speed

While driving my 2024 Hyundai Tucson Hybrid at approximately 20-25 mph approaching a red light, a sudden and total loss of brake power-assist occurred. Upon applying the brakes, the pedal became instantly rigid and rock-hard. Despite pumping the pedal multiple times and applying heavy manual foot pressure, the vehicle failed to stop, resulting in a low-speed rear-end collision with a stationary car stopped at the traffic light. No dashboard warning lights or malfunction indicators illuminated during or immediately following the event. After the collision, the vehicle's ignition was turned off and then restarted. Following this power cycle, normal braking functionality temporarily returned. The low-speed impact displaced an ultrasonic sensor in the front bumper. This intermittent electronic brake failure poses a catastrophic safety hazard to pedestrians and occupants if it recurs at higher speeds

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.

On Sunday evening [XXX] at [XXX] I was returning from Long Beach on the [XXX] home to Los Angeles, when I went under an overpass and my emergency braking system activated with an alarm and red arrow pointing to the left. There was no warning before this event. Then my lane assist stopped me from going over the line into traffic. A few minutes later the same thing happened again.

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.

On March 6th, 2026, I spent the day running errands in normal driving conditions and it created a situation that did not charge the battery or switch to gasoline. Several error lights displayed seconds before the car died. The hazard lights failed within 15 minutes of waiting for a tow truck. The dealership service department charged the battery and gave me advice to run the car at least 30 minutes everyday even if runs only in the garage. They told me that it was user error because I don't need to drive a half hour per day. I am still attempting to determine the real issue and have it addressed.

Third time SUV was parked for multiple days without being started and the main battery did not keep the charge. First time was five days and required a battery jump. Then it was 22 days, and as expected, the battery did not keep the charge and required a jump. This week it was eight days and same thing happened. I know the SUV is a hybrid but the main battery should not be run down to not be able to start the engine after a short time not being started. My brother has a 2014 Ford product hybrid and does not have any battery issues when that hybrid vehicle is not started for a period of time.
