Automatic Transmission problems of the 2010 Lexus IS

2008 Lexus Is250 awd had pulled into a parking space on a slight incline and stopped. When the operator tried to put the vehicle into park the engine revved and car moved violently forward climbing an eight inch curb to hit a concrete column on the front of an office building. The driver had their foot off the gas and applied the brake to no effect, when the driver moved the gear shift into neutral the car returned to normal and the driver was able to back off the column in reverse and park the vehicle. Have turned the car over to Lexus and a factory field representative Is scheduled to examine. Car Is at Toyota knoxville body shop.

This 2010 Is250 was purchased new in October 2009 and has approximately 3,300 miles. On Feb 19th, 2010 driver made a u-turn at low speed. After the completion of the turn the car started an uncommanded acceleration, causing it to spin to the right. The car then jumped a curb with the wheel still spinning and the bottom resting on the curb. Pushing and holding the start/stop button in the car finally cut the engine. Significant damage to the underside and left rear wheel of the car. This vehicle Is unsafe to drive as uncommanded acceleration could have led to serious injuries or death. Vehicle Is currently located at south bay Lexus in torrance CA.

Currently have a 2010 Lexus Is250 awd (bought on 2/9/2010) and noted on several occasions that the rpms increase randomly after the car has stopped and Is stationary. The car inches forward and the driver has to apply more pressure on the brake pedal to make sure the car doesn't lurch forward and hit the car in front. The rpms go up almost 1000 rpms from idling. Happens in d and r. When turning on car putting the gear r the car just lurches backwards unless the brake pedal Is heavily depressed. This seems to be a software / ecm Issue as the accelerator pedal Is not being inadvertently being pressed. As this car Is not even one week old, I want to return the car. Can you please help me with this?.
