Section 426

Three times since Jan. 19, my 2004 Solara has had an instance of sudden acceleration when I tapped the brake pedal. The last time happened on Feb. 7 when I tried to slow down as I was going over railroad tracks. I had to hit the brakes to stop the acceleration. Has anyone else had this problem, or is aware of this problem? Since it only happens occasionally, I'm afraid that if I take it to the dealer, he won't find anything wrong with the car and will tell me that there is nothing wrong with it. The car has fewer than 32,000 miles on it.
