DETROIT (AP) - U.S. safety officials have closed an investigation into allegations that three Ford SUVs can roll away when the transmissions are in park.
The National Highway Traffic Safety Administration says the probe involved about 1.5 million Ford Explorer, Mercury Mountaineer and Lincoln Aviator SUVS from the 2002 to 2005 model years.
The agency determined that failure rates weren't high enough to order a recall. The probe began in April 2009 and was closed last month. The safety agency found 36 complaints including 14 crashes and six injuries.
Investigators found that the park gear in the transmission failed only 4.4 times per 100,000 vehicles. A system that prevents the car from being shifted into gear unless the driver's foot is on the brake failed only 3.4 times per 100,000 SUVs.
General Motors is recalling more than 6,000 big vans and SUVs because their steering can fail. The recall affects certain 2012 Chevrolet Express and GMC Savana vans, and Chevrolet Suburban and GMC Yukon XL SUVs.
The National Highway Traffic Safety Administration said on its website Saturday that a gear shaft can break, causing a loss of steering. GM says no crashes or injuries have been reported.
