This has happened twice now. When going at a low speed, once in traffic, once while performing a U-turn, while braking, the car is trying to accelerate. I have to practically stand on the brake pedal to avoid the car lurching forward. I saw no warning lights on the dashboard. I haven't yet brought the vehicle to a dealer or service center, but it will be.

Center rear buckle fails to latch. Plastic case separated after normal operation of closing/folding down the rear seat. Buckle case separated from buckle latch. Buckle would latch with plastic cover missing, however would be a considerable risk, as a the retaining bar feature is not captive to the buckle and would separate in use, if used. As well as a pinch hazard. The center buckle was only use a handful of times and is free from contamination/debris. A safety buckle shouldn't fail under normal operation of folding a seat as designed. The seat folding action caused the buckle casing to pop off and separate.

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

Subject: Urgent Drivability Concern – 2024 Hyundai Tucson (6/22 Incident) Vehicle: 2024 Hyundai Tucson Date of Incident: XXX Trip Details: [XXX] to [XXX] (~160+ miles) Summary of Issue: During a long-distance drive on XXX, the vehicle experienced severe and consistent drivability issues that created unsafe driving conditions. Symptoms Observed: •Severe loss of acceleration / stalling behavior throughout the entire trip •No check engine light illuminated at any time •When pressing the accelerator: oTachometer increased (RPMs rising) oVehicle speed decreased or failed to increase appropriately •Significant delay in acceleration, especially when: oMerging onto the interstate oPassing other vehicles •Cruise control behavior: oSeemed to manage acceleration more effectively than manual throttle oHowever, still exhibited slow response when additional acceleration was required •Auto Start/Stop system: oSystem automatically disabled itself oWould not allow reactivation during the trip Safety Concern: This condition made it difficult and unsafe to: •Merge into traffic •Maintain appropriate highway speeds •Execute passing maneuvers Dealer Visit (Near [XXX]): •Vehicle was inspected after sitting for a couple of hours •Dealer reported no issues found •However, the problem was persistent and clearly present during operation under driving conditions Took vehicle to a dealership in Raleigh and asked that they look at the fuel injectors. They determined that all 4 injectors were failing and replaced them under warranty. Concerned that Hyundai America has not issued a recall as driving the vehicle with this issue creates a serious safety concern that would lead to injury or loss of life INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Automatic emergency braking stopped the vehicle because another vehicle in front turned right.
