I just bought a 2007 ES on a buyback program. I love the car but I am concerned about the transmission. I started the car annd ran about a 1/4 mile trying to make a light. I did not go 100MPH about 35 at best. I did not make the light and came to a stop. Once the light changed the car would not move. The engine was running but nothing. Finally slowly but surely it responded. What happened? I thought Lexus would be super careful about reselling these cars.
