2023 Hyundai Santa Fe FORWARD COLLISION AVOIDANCE

On two occasions, once at 70mph and once at 45mph vehicle suddenly lost power and displayed warning to check collision system, there were no vehicles close enough to warrant this. I had to limp the car to the side of the road as safely as possible and shut car off, wait a few minutes and restart vehicle to clear error and allow proper power/ acceleration again.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving at various speeds, the Emergency Braking System was erroneously activated, causing the vehicle to abruptly stop in the middle of the road. During the failure, the message "Emergency Braking System Engaged" was displayed. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The manufacturer was not contacted regarding the failure. The failure mileage was unknown.

Emergency brakes engage while driving for no apparent reason. This has happened on several occasions over the last 6 months.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving at various speeds, the Forward Collision Avoidance system erroneously activated, causing the braking system to activate and the vehicle to veer to the left. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer on several occasions due to the failure however, a cause for the failure was not determined. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 1,000.

The front collision warning/assistance system on this vehicle does not appear to be working. The dealer claims that it is working. It seems that the protocol for testing for proper function is flawed and no one is tacking ownership of this issue. They are saying that in order to test the system a near collision must be imminent and to simulate this puts the technician at risk of injury (understandable); Nevertheless, I have been in situations where I should have at least received a warning and there was none. On a test drive by the service manager with me in the vehicle the front collision assistance was verified on and active. The cruise control function was tested and worked to adjust the speed of the vehicle appropriately which tells me that assistance is available. It appears that the either the collision sensor is not recognizing collision danger or the danger message is not getting to the warning trigger and possibly the assistance trigger. This situation should be reported to the appropriate department a Hyundai for review.

When traveling along the front collision warning system is triggered even though nothing is around the vehicle. The car remains running, but there is no response from the gas pedal. I have to coast to the side if possible or stop and turn on flashers (very dangerous on interstate highway). Once safely stopped, turning off the car and then starting again reboots the system and it runs fine until it happens again randomly. The check engine light stays on for a day, but does not light up the next morning. The dealership does diagnostics, but nothing shows up as wrong. It happens so fast there is no way to take a picture or video before the warning disappears. So far I have been lucky as this has happened at least 6 times. It is dangerous and I am terrified someone will not see flashers and run into me at highway speeds.

Forward collision warning system engaged unexpectedly, braked hard to the point of smelling burnt tires. No collision imminent. Normal driving conditions. On a second occasion, stopped at a traffic light, the vehicle suddenly warned of foward parking collision. Front camera engaged and yellow warning showed
