State Farm says it saw an uptick in reports of unwanted acceleration in Toyotas from its customer database and warned the National Highway Traffic Safety Administration. For their part, NHTSA officials said the report was reviewed and the agency issued a recall later that month.

NHTSA received complaints about acceleration problems in Toyota vehicles as early as 2003, and congressional investigators are looking into whether the government missed warning signs of the problems. A congressional hearing into the Toyota recalls planned for tomorrow has been postponed because of a snowstorm expected to hit the U.S. capital.

The House Committee on Oversight and Government Reform now plans the Toyota hearing on Feb. 24.
