“I am requesting that DOT NHTSA investigate the electronic acceleration system and/or the ECM causing sudden unintended acceleration of my 2007 Toyota Matrix. On 9/18/2010 my son was driving my 2007 Toyota Matrix. He was pulling into a parking space in front of a store & was almost completely stopped when, even though he had his foot off the accelerator & on the brake, the car began to accelerate on it's own. He then pushed harder on the brake & turned the wheel & the vehicle continued to accelerate. …”
