Toyota has released its preliminary findings on the Prius that allegedly sped out of control on a California highway last week.
Tests over the weekend found no evidence of a problem with the car, casting doubt on the driver's story.
James Sikes insists his Toyota Prius sped out of control last Monday
and his brakes couldn't stop it.
Toyota says it found "significant inconsistencies" between its tests and Sikes' story.
"At no point did overheating of the brakes prevent it from coming to a stop," says Toyota's Bob Waltz.
Toyota and government experts tested Sikes' car over the weekend, but said when they gunned the accelerator and pressed the brakes together, his car slowed down.
Toyota says its brake override system worked every time.
The National Highway Traffic Safety Administration reports:
"We have not been able to find anything to explain the incident" but admits it's hard to re-create the problem and says they may never know what happened."
Still, one auto safety expert says those tests don't always tell the whole story.
"As an electronic engineer will tell you, you must test around 1,000 vehicles for 30 days before you begin to find the beginnings of the problem," says the Center for Auto Safety's Clarence Ditlow.
Both the Toyota and government investigations are ongoing.
