Date: April 10, 2009

Victim: Unknown

Location: Unknown; complaint filed from Fort Meade, Md.

Model: 2006 Lexus IS250

Details: After experiencing sudden acceleration up to 90 mph, a 2006 Lexus IS250 owner attempted to remove the floor mat, he said in a complaint filed with the National Highway Traffic Safety Administration in December from Fort Meade, Md.

The vehicle veered off the road, rolled over and landed in a ditch, ejecting one unrestrained passenger who died, the complaint said. Three other occupants experienced bruises and lacerations serious enough to send them to the hospital.

Maryland State Police reported three fatal accidents in the state on that date, but none involving a Lexus.
