NHTSA is beggining an investigation into the 2010 Ford Fusion, after recieving complaints of cracking wheel studs on the popular family sedan.
Over 280,000 vehicles may be affected by the problem. Wheel studs hold the wheel in place on the vehicle, and a failure could be catastrophic. Interestingly, NHTSA claimed that "Three complaint vehicles belong to the same 22-vehicle fleet but were assigned to different drivers who experienced the alleged defect on three separate occasions", meaning the defect could be localized to a specific batch of cars.
NHTSA says that the vehicles in question all have fewer than 10,000 miles on them, and have never had the wheel studs or lug nuts serviced.
