2021 Hyundai Santa FE Forward collision avoidance Problems

“The forward collision system is automatically being activated without any car or object near the front of the vehicle. It happened 3 times while on the freeway and highway. The system automatically slams on the brakes, the vehicle swerves a little to left and right due to the sudden application of the brakes, and a large red waring indicator appears on the dash. We were nearly rear ended while travelling about 65 miles/hr because of this. We turned off the system, but every time the car is started, it automatically turns this feature on!! So you always must remember to turn it off. …”

“Was coming off an exit on the interstate and started slowing down. My brakes act like they didn’t want to work. Grinding and the pedal was twitching under my foot. The car stopped thankfully, but then all Linda of lights came on the my dash and will not go off. And 3 warning come up!”

“There were 2 instances where my vehicle stopped. Once I was driving 15mph and it said “Put car in Park”. The 2nd, I was driving 45mph and the vehicle said “Step on the Brake to start car”. I have also had 2 instances where my odometer just keeps going up and down. He 2nd instance, the car was making a ticking noise and hazard along with other lights were flashing.”

“On 1/1/26 while traveling on the highway with no traffic in front of or right of my vehicle the ADAS emergency brakes applied themselves and slowed the vehicle nearly causing my vehicle to be rear ended. Vehicle is available for inspection. Faulty assistance nearly caused a rear end collision along the highway. Not aware of ADAS being tested inspected although multi-point inspection was done 10/2025. No warnings prior to incident.”

“While driving in the fast lane on the freeway at speed limit the car suddenly began to slow/stop, after which a warning flashed on the display that said Danger, collision imminent, or something like that. There was no one close in front of me when that happened. This exact scenario has happened three times now in this car, in the same way! I felt my life was endangered every time by the sudden and unnecessary braking of my car.”
