| The vehicle was purchased on january 26 2006 new with lees than 100 miles on it. while at a complete stop in a parking place with my right foot on the brake pedal and hand on gear shift to place the car in park in front of a nursing home. suddenly the car accelerated forward out of control with enough speed in the short distance to go through a wall into a room of the nursing home. luckily the room in the nursing home was unoccupied. i did suffer an injury to the top and right side of my right foot, when i attempted to pull the accelerator up with my right foot and placing my left foot on the brake pedal. the car did not stop accelerating until the impact into the nursing home. the car was towed to the dealership the same day and the owner of the dealership and service personnel was notified of the possible defect. to this date the dealership has not responded to my concerns. *nm | |||

| This car has a dangerous defect. randomly when in a stationary position, by holding the brakes, the engine and transmission sometimes suddenly accelerates powerfully, making it difficult to hold the car. i notified the dealer about this defect, several times in writing and by phone. dec, 29, 2005 they took it on a drive, and claimed to have found no defect. subsequently, jan, 15, 2006 at approximately 1:00 pm, i was stopped at a red light on grand st. nyc behind an suv, by holding the brakes, all of a sudden it accelerated, and it was impossible to hold the car. it slammed into the suv in front of me, smashing my front. luckily, the suv was not damaged. but even more luckily, we did not get hurt, (i had in the car my wife, an adult daughter, and 2 grand children). in addition, i guess we were extra lucky that we had the suv in front of me, which averted a catastrophic mowing down of pedestrians crossing. the dealers took in the car, and notified me yesterday, jan, 19, 2006, that they ran tests and find nothing wrong with the car. *jb | |||

| Dt: when applying brake pedal pressure the pedal goes past the accelerator to the floor, most often this occurs when starting the vehicle and placing it in gear. when this occurs it is easy to hit the gas pedal as well when trying to apply brake pressure. this causes the tires to squeal and the car to lunge forward. has been to a dealer who said he would have a service manager call the consumer about this problem, but he never returned the call. the service representative noted there was nothing wrong. no repairs or changes have been made. *ak | |||
