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.

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 grandchild just went from a car seat to a booster seat. The back seatbelt buckle is so recessed that you cannot buckle it without 20 minutes of fighting with it! This is a major problem because a child could not get themselves buckled. And it takes an adult 20 minutes to try and buckle the shoulder belt into The seat buckle because it’s so recessed in the backseat. I looked on the Internet to see if there was a way to loosen the belts or extend them from the back and there is nothing so I went to a Hyundai Tucson forum and I see there have been many complaints About the recessed seat buckle not being accessible. This is a major concern for anyone transporting children and their grand grandchildren. I’ve already complained to Hyundai about the car randomly shutting off. Hyundai needs to put out a fix for this or provide Hyundai owners with some kind of extension for that buckle. I also understand that taking it into the dealership didn’t help, because they couldn’t buckle it either.

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)

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.
