2025 Hyundai Santa Fe

Bought this brand new Santa Fe in July 2025 and on day 5 after purchasing this vehicle, car stopped accelerating while driving on highway, which is a serious safety concern. Took the vehicle back to the dealership and turned out the issue is with failed catalytic converter and they had to replace it. Since then, the acceleration has not been that great and had continuous issues with random engine noises etc

Yesterday while I was driving I almost was hit by another car in an intersection. My car did not respond fast enough, the engine did not have any stregth. I found today after I took it for service that it needs a replacement of the oil pump. My car is new it only has 4 months of usage and this type of repairs is done in vehicles with a high mileage. This is very uncommon.

I am reporting a critical safety defect involving my brand-new 2025 Hyundai Santa Fe. While driving on the freeway, the vehicle experienced a complete brake system failure, nearly causing a serious accident. My boyfriend was driving at the time, and when he tried to brake, the vehicle did not stop. He had to take immediate evasive action to avoid crashing, which put both of us — and nearby drivers — in immediate danger. The vehicle was purchased about a month ago and had never been serviced or modified. After the failure, it was towed to Hanlees Auto Mall Hyundai in Richmond, California, where the service department inspected it and confirmed the problem was caused by a missing clamp, which is a critical component of the braking system. This appears to be a manufacturing or dealership oversight. They took photos, documented the issue, and made the repair — but they also told me they cannot guarantee this won’t happen again. There were no warning lights, messages, or symptoms before the failure — the brakes simply stopped working during operation on the freeway. As of now: •The issue has been confirmed by Hanlees Hyundai in Richmond. •I have not yet received a loaner vehicle. •The car is currently in my possession, but I do not feel safe driving it. •I have been in contact with Supervisor Steve at Hyundai of Vacaville, who has offered to pick up the vehicle and provide a loaner, but that has not yet occurred. This is an extremely dangerous failure that occurred on a brand-new vehicle. I am requesting a formal investigation into this issue to determine if it’s isolated or part of a broader manufacturing defect with the 2025 Hyundai Santa Fe. A missing brake component that results in total failure at freeway speeds is a life-threatening safety hazard and should be taken seriously by the manufacturer and federal safety officials.
