2024 Hyundai Santa Fe Brakes Problems

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.

Bought in Sept 2026 with 30,000 miles. Would not stop when breaking at low speed but would jerk and accelerate, causing me to drive through red lights and stop signs. How to swerve to avoid collisionHappened about 6 times. Returned to dealer. States could not duplicate. Traded car in

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)

The vehicle was purchased brand new and at near 8k miles the brakes became warped. It caused severe shaking on the highway and has continued to get worse. Hyundai confirmed the brakes were bad but refused to replace the rotors. Rotors on a new car should not be warped at 8k miles, cheap materials lead to that

The contact owns a 2024 Hyundai Santa Fe. The contact stated that while pulling into an automatic car wash and depressing the brake pedal, the brake pedal travelled down to the floorboard, and the vehicle failed to respond. The vehicle then drove into the car wash while the car wash conveyor system was not engaged. The contact stated that the failure recurred while driving 2-3 MPH in a parking lot, and the vehicle rear-ended another occupied vehicle. There was no damage or injury sustained. Additionally, the contact stated that while driving 5 MPH and pulling out of a parking lot, the brake pedal was depressed, but travelled down to the floorboard, and the vehicle failed to respond. The contact pumped the brake pedal, but the vehicle failed to respond and rear-ended another occupied vehicle.

When placed in "Park" the vehicle's brakes did not engage, which allowed the vehicle to roll backwards when I exited the vehicle. I was able to reproduce the problem again and I recorded a video showing the problem. When pressing "Park" on the electronic shifter, the dashboard displays that the video is in "Park". However, the brakes are not engaged as evidenced by the vehicle rolling backwards when I take my foot off the brake. After reproducing the issue a couple times (~ 10 minutes later) and documenting the issue with a video, the check engine light eventually came on and the dashboard displayed: "PARK malfunction. Engage parking brake when parking vehicle." Which quickly changed to the warning message: "Shifter system malfunction! Service immediately" The vehicle would no longer let me place it in "park" and it remained on in "accessory mode" and I was unable to turn off "accessory mode" since the vehicle could not be placed in park. However, neither of these error messages appeared the 3-4 times I was able to place the vehicle in "park" and then observe it roll back. The vehicle has been towed to Northwest Hyundai for inspection/repair. >> How was your safety or the safety of others put at risk? The car rolling uncontrolled is a huge safety hazard to anyone that happens to be in the path of the car. It is also a huge safety hazard to any occupants that might remain in the vehicle when the driver exits after placing it in park. >> Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The service error that appeared prevented the car from being placed in "park". However, I was able to capture a video of the problem. >> Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there were no error messages of any kind.

Since buying this vehicle I have had problems with shaking while braking… specifically while going at a higher speed downhills. At 3000 miles I took it in and they shaved down my rotors and stated it would need to be replaced if it didn’t fix it. The problem continued, when I would bring it to the dealership they would deny being able to replicate the problem. Upon searching on Reddit I saw that others are having problems with their rotors on their Santa Fe prematurely needing replacement. This has been a problem since I bought the car and I feel like it’s a significant safety problem that Hyundai will not cover under warranty.
