   I am [XXX] old, have been driving since I was 16, and until this incident, have never been in an accident. On [XXX], I was parallel parking in my friend's quiet suburban neighborhood, as we do yoga together every Sunday morning. I reversed into the space. Then I wanted to pull forward slightly to straighten out my vehicle. As I shifted into drive, I recall hearing the engine rev. My foot was on the brake but the car lurched forward at about 25 mph and rammed into the car parked in front of me, crunching his rear tail light and bumper and damaging the front of the passenger side of my vehicle. As soon as my car hit the car in front of me, it stopped. My foot was on the brake during the entire incident. Lexus is supposed to finish their 45 day investigation soon. But they did not seem concerned that I am still driving this vehicle. I am worried it could happen again and this time could be far worse.

Dealer replaced the car battery for this problem. There were times when the doors do not open for a few minutes. There were a few times that it seemed that the car did not come to a complete stop. There are many times that the car would jerk a bit and come to a sudden stop on its own when the car was driven normally and safely.
