Toyota is recalling 615,000 Toyota Sienna minivans in the U.S. over problems with a shift lever assembly that could cause a vehicle rollaway, the automaker said this week.

The vehicles were released for the 2004-05 and 2007-09 vehicle years.

Approximately 21 minor accidents and two injuries have been reported in the U.S. related to the defect, according to Cindy Knight, a Toyota spokeswoman, who spoke with Edmunds.

"Because of the potential for damage to the shift lock solenoid installed in the involved vehicles, there is a possibility that the shift lever could be moved out of the 'P' position without the driver depressing the brake pedal," said Toyota in a press statement. "This could result in a vehicle rollaway."

The affected vehicles were produced between January 2003 and August 2005 and between February 2007 and December 2008, Knight said.

The recall is expected to begin in mid-October.

The National Highway Traffic Safety Administration has yet to comment on the recall as of press time.

Toyota dealers will replace the shift lock solenoid in the affected minivans, free of charge.
