A plaintiffs' attorney says Toyota Motor Corp. has reached a settlement in a case involving hundreds of lawsuits over accelerations problems. Steve Berman said today the settlement, which still needs a federal judge's approval, was worth more than $1 billion and is the largest settlement in US history involving automobile defects. Toyota has recalled more than 14 million vehicles worldwide due to acceleration problems in several models and brake defects with the Prius hybrid. Toyota has blamed driver error, faulty floor mats, and sticky accelerator pedals for the unintended acceleration. (More Toyota stories.)
