Runaway Prius The New 'Balloon Boy?'

Gov't Cannot Explain Runaway Prius Incident

National Highway Traffic Safety Administration says it has not been able to find anything to explain the reported incident of sudden, high-speed acceleration in a Toyota Prius on a San Diego freeway.

WASHINGTON -- The federal government said Monday it cannot explain a reported incident of sudden, high-speed acceleration in a Toyota Prius on a San Diego, Calif., freeway last week.

The National Highway Traffic Safety Administration said in a statement that it continues to investigate but "we may never know exactly what happened with this car."

The agency said its engineers are reviewing data from the Prius owned by James Sikes to try to understand what happened with his hybrid. But so far, NHTSA says it has not been able to find anything to explain the incident that Sikes reported.

Sikes called 911 last Monday to report losing control of his Prius as the hybrid reached speeds of 94 mph. A highway patrol officer helped bring the vehicle to a safe stop.

Inspectors in California tried during a two-hour test drive to duplicate the acceleration, but were unable to do so.
