Toyota Motor Corp. has moved to dismiss a complaint in the multidistrict litigation (MDL) involving unintended acceleration defects, claiming that plaintiffs’ lawyers are “seemingly faced with an increasingly uphill battle to define any technical problem” with Toyota’s electronic throttle control system.

Toyota’s reply brief, filed on Monday, addresses new claims asserted in an amended complaint against the company in the MDL, which involves more than 200 economic class actions brought on behalf of consumers and businesses and about 100 personal injury and wrongful death claims. Toyota’s filing and the amended complaint pertain only to the economic damages claims.
