The contact owns a 2020 Hyundai Santa Fe. The contact stated that while her husband was driving at an undisclosed speed, the vehicle was not able to stop immediately while the brake pedal was depressed, causing his vehicle to rear-end another vehicle. The failure recurred on a separate occasion while the contact's husband was driving, and the brakes failed to stop the vehicle from crashing into their daughter's residence. The air bags did not deploy in either collision. No injuries were sustained and no medical attention was received for either collision. No police report was filed for either collision. The contact's husband was able to drive the vehicle away from both the scenes of the collisions. The vehicle's front end was damaged; however, the vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 28,000.
