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.
