WASHINGTON - The U.S. government says it has received more than 60 complaints from Toyota drivers who say their cars have sped up by themselves even after being repaired to correct the problem.

The National Highway Traffic Safety Administration says it is contacting every owner to learn more about the complaints. The complaints, which are submitted online or through a NHTSA hot line, have not been verified independently.

The government says NHTSA can order Toyota to provide a different solution if if necessary.

As part of two recalls involving more than 8 million vehicles worldwide, Toyota is installing special metal shims and shortening gas pedals to solve the problem of unintended acceleration. The Japanese automaker blames the problem on gas pedals that can become sticky or be trapped under floor mats.
