On 4 separate occasions- 2 times each for 2 different drivers, occurring about every 1200 miles, our Lexus hs250H accelerated during a stopped or braking situation. We brought it to the dealer and contacted Lexus customer service. The response: [there is nothing wrong and the vehicle is operating normally. You are either using the accelerator and brake at same time or just experiencing the gas engine starting up which is giving you the sensation of moving when you actually aren't moving. This sensation is normal for both priuses and Hs 250 models.] I can usually tell when the gas engine fires up and the sensation is definitely different than the scary problem we are having. When asked what to do if this causes an accident the response was: [contact your insurance company]. clearly Lexus has no intention of admitting that there's anything wrong. No salesperson informed us that the normal operation of the car includes sudden acceleration or the "sensation" of it. Two incidents caused my wife to slam on the brake in bumper to bumper traffic to avoid hitting the car`in front and one incident caused me to hit an object in my garage.
