Toyota's investigation of sudden acceleration in some of its cars is shifting to upstate New York, where a driver said her Prius sped up on its own and slammed into a stone wall.

Technicians from Toyota will join government investigators in Harrison Wednesday to inspect the car. Toyota plans to examine an internal data recorder that documents the moments before and after a crash.

The company will use equipment to determine how many times the driver hit the brakes and gas. It used the same tools earlier this week to cast doubt on a California driver who claimed his Prius sped to 94 mph before a patrol officer helped him stop it.

In the Harrison case, authorities have said there is no indication of driver error. A housekeeper told police the car sped up on its own as she eased forward down her employer's driveway on March 9 and hit a wall across the street. She was not hurt.

Toyota recalled more than 8 million cars because their gas pedals could become stuck or be snagged by floor mats. In addition, the government is looking into complaints from at least 60 Toyota drivers who say they got their cars fixed and still had problems.

The investigations reflect challenges faced by the company and government. Dealers and experts have had trouble recreating episodes of sudden acceleration.
