Automatic Emergency Braking problems of the 2024 Hyundai Santa Fe

Vehicle will not brake assist in the front even though all of the settings are selected it to work and assist in the event of needing to brake suddenly.

Vehicle identification number (VIN): [xxx] make: Hyundai model: Santa Fe year: 2024 description of the issue: •component or system that failed: the vehicle’s brake system, including the emergency braking system, failed to slow or stop the vehicle at low speeds. The problem is available for inspection upon request. •safety risk: this failure endangered my safety and others. While driving slowly in traffic, I fully pressed the brake pedal, and the emergency braking system activated, but the vehicle did not slow or stop, causing a minor collision with another vehicle. •reproduction or confirmation: prior to the incident, on two separate occasions, I noticed the brake pedal felt loose or like it “released” at low speeds, forcing me to press harder for the vehicle to slow. These issues were not previously inspected or documented. I was planning to have the brake issue inspected along with a current recall and other concerns, including a stiff seatbelt buckle and a door that was difficult to open, as soon as I had the chance. I have not received any formal recall notice by mail or email. I learned about the recall during routine maintenance at the dealership. •inspections: the vehicle has not yet been inspected by the manufacturer but I plan to take it to an authorized Hyundai dealership ASAP for inspection. The accident has not been reported to the police or insurance yet but it will be first thing tomorrow. •warning lamps or symptoms: no warning lights appeared, but there unusual brake behavior was noted on two occasions about two weeks before the crash. Thought this time was significantly worse, and by worse this I mean the vehicle didn’t brake. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After car is idle, when pressing the gas, the car instantly stops as if you have slammed on the break, feeling like you have driven into a brick wall. The intensity of the stop causes you to jerk aggressively in your seat. This has happened on more than one occasion. Without a seatbelt it would cause injury as well as the possibility of causing an accident with other vehicles. When this happens, there were no warning lights or messages shown to indicate an issue. The vehicle is currently at the dealership as of 9/20/2024, they are trying to replicate the issue however it has been more than 2 weeks, and they have not found a resolution. They have run diagnostics tests and there was nothing that indicated the issue with the vehicle. As of today, 10/9/2024, the issue has not been resolved and the vehicle remains in the dealers possession.

Purchased this car new from crain Hyundai, conway ar, on 4/1/2024. On 4/3 we called dealer because bluelink reported 13 maintenance critical issues needed immediate service. Took the vehicle to dealer on 4/4. They worked on vehicle, said they fixed issue and notices would disappear over night. Issues did not, so 4/5 dealer had vehicle picked up, loaner left, and they would fix in 2 days. Issues still not fixed on 4/8. They have no idea how to fix and they want us to accept vehicle as-is. Was told this morning by dealer staff that there has been multiple occurrence of this issue and not fixed.
