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

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 Tucson is applying Automatic Emergency Break without a reason. It happened to me 3 times in a week with my Tucson Hybrid 2024 NLine, it was scary and I was on freeway at 70+MPH and couldn't capture the warning as it popped out for only 3 sec. I see no cars around when this happened and when I checked few forums I see this as a common problem in Hyundai vehicles in recent times and feeling scared. I was lucky enough last week as there is not vehicle behind me when breaks applied automatically.

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.

I was driving home on Christmas day 2023 in my 4 month old 2024 Hyundai Tucson Hybrid. An hour into my 4 hour drive my car began making a low whump whump sound. No alerts or alarms came on my display to indicate anything was wrong. The noise was off and on for a couple miles. Suddenly my emergency brakes slammed on, my dash went red and the alarms went off. No one was in front of or around me. Had someone been behind me I would have been rear-ended. This was while I was going approximately 75-80. It could have caused a massive wreck had the freeway been congested. The noise went away after that and I made the rest of my trip without incident. The dealer said they couldn't replicate it and the analysis showed nothing was wrong so there is nothing they can do. I have found web forums and a Reddit thread with numerous people complaining about the exact same issue with their newer Hyundais. So far a lemon lawyer seems to be the only recourse.
