Toyota’s Work with Exponent


February 24, 2010

In December 2009, Toyota Motor Corporation (TMC) retained Exponent, one of the country’s leading engineering and scientific consulting firms, to help the company evaluate reports of unintended acceleration in Toyota and Lexus vehicles equipped with the Electronic Throttle Control System with Intelligence (“ETCS-i”) system.

Toyota released an interim report from Exponent and provided it to the House Committee on Energy and Commerce. This report summarizes some of the testing that has been performed. Exponent’s testing and analysis is on-going.
