SAN DIEGO -- Toyota says it has done a thorough inspection of the Toyota Prius that reportedly sped out of control on a San Diego highway last week and have found no evidence that the car malfunctioned.

Toyota says the accelerator pedal was tested and found to be working normally and a backup safety system worked properly. The automaker says the front brakes showed severe wear and damage from overheating but the rear brakes and parking brake were in good condition.

"While a final report is not yet complete, there are strong indications that the driver's account of the event is inconsistent with the findings of the preliminary analysis," according to Toyota.

James Sikes says his car raced to 94 mph on a freeway near San Diego last week. The March 8 incident ended when Sikes stopped the car with help from a California Highway Patrol officer.

The federal government also released a statement Monday saying it cannot explain the incident either.

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 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.

John Gomez, an attorney for Sikes said the failure to repeat the incident is insignificant and not surprising.

"They have never been able to replicate an incident of sudden acceleration. Mr. Sikes never had a problem in the three years he owned this vehicle," he said Sunday.

But Kurt Bardella, a spokesman for Rep. Darrell Issa, R-Calif., said the failure to duplicate the stuck accelerator, along with a vehicle design to prevent such occurrences, raises questions about the driver's story.

"We're not saying Mr. Sikes is wrong or that he lied, we're saying that questions have arisen in the investigation," Bardella said.

NHTSA is looking into claims from more than 60 Toyota owners that their vehicles continue to accelerate unexpectedly despite having their vehicles repaired.

Technicians with the NHTSA and Toyota could not duplicate what Sikes said he experienced March 8 on a mountainous but lightly traveled stretch of Interstate 8 east of San Diego, according to a congressional staffer's memo prepared for the House Committee on Oversight and Government Reform.

"Every time the technician placed the gas pedal to the floor and the brake pedal to the floor the engine shut off and the car immediately started to slow down," the memo read.

According to the memo, a Toyota official who was at the two-day inspection last week in suburban San Diego explained that an electric motor would "completely seize" if a system to shut off the gas when the brake is pressed fails, and there was no evidence to support that happened.

"In this case, knowing that we are able to push the car around the shop, it does not appear to be feasibly possible, both electronically and mechanically that his gas pedal was stuck to the floor and he was slamming on the brake at the same time," according to the memo.

Toyota has recalled millions of cars because of floor mats that can snag gas pedals or accelerators that can sometimes stick. Sikes' car was covered by the floor mat recall but not the one for sticky accelerators. He later told reporters that he tried to pull on the gas pedal during his harrowing ride, but it didn't "move at all."
