NHTSA complaint #10323660, filed 2010-04, 100 miles“My wife was returning home with her 2011 Toyota Sienna van. She pulled into the driveway, took her foot of the gas and put on the brake but the van accelerated right into my 2011 ford fusion, causing a lot of damage.

My wife is now afraid to drive the vehicle and we don't know what to do?”
