2023 Hyundai Santa Cruz

Sudden Unintended Acceleration: Coming to a stop in a driveway and planning to put vehicle in to reverse, the Santa Cruz suddenly accelerated and kept accelerating ... it would not stop moving, brakes were applied continuously and forcefully, but with no effect. Vehicle crashed through shrubbery and small trees into neighbor's yard, over a retaining wall and finally crashing into neighbors parked classic car, only stopping after it nose-dived downward. We live in Rapid City, this event happened at our daughter's residence in Black Hawk, South Dakota.

The emergency brake system comes on while driving 60 - 70 miles an hour on freeway. It has happened twice. It does not happen every time I drive 60 - 70. The light comes on stating Emergency Braking and my vehicle slows down. It does not last for very long then goes away. I took it to the dealership and it did not do it for them. They kept it 3 days.

The contact owns a 2023 Hyundai Santa Cruz. The contact stated that while driving 60 MPH with the cruise control feature activated, the braking system erroneously activated causing the vehicle to abruptly decelerate. After parking and restarting the vehicle, the vehicle operated normally, and the failure was corrected. The vehicle was later taken to the local dealer who was unable to determine the cause of the failure. There was no repair performed. The contact stated that the failure had reoccurred. The manufacturer was not yet contacted. The failure mileage was 1,000.

On 04/26/23 a lamp assy-rear comb outside Qty: 1 installed 92402-K5000, was replaced due to condensation inside the taillight. On 09/22/23 both taillights, lamp assy-rear comb outside Qty: 1 installed 92401-K5000, was replaced and lamp assy-rear comb outside Qty: 1 installed 92402-K5000, were replaced due to condensation inside the taillights. Should the condensation in the taillights cause the brake and or turn signal lights to fail this could cause a serious accident! I have an appointment at 1:00 PM at my dealership Hyundai of Anderson in Anderson, SC to have both taillights inspected for the third time, tomorrow on 10/10/2023 because of condensation inside them. I might add that the condensation has occurred when there has been no rain on the vehicle and the vehicle has not been washed. My Santa Cruz is also housed in a completely enclosed garage.
