DETROIT (AP) — U.S. safety regulators are investigating coolant leaks in Porsche 911 sports cars that could cause drivers to lose control of the cars.
The probe affects about 10,000 models with the GT1 engine from the 2001 through 2007 model years.
The National Highway Traffic Safety Administration says a hose fitting can fail and cause rapid coolant leaks without warning. The coolant can cover the road and cause drivers to lose control of their cars.
The agency says it has 10 complaints of coolant leaks. One driver said a 911 lost rear tire traction because a leak, sending the car into a spin and off the road.
Investigators will determine if the problem has caused any injuries and if it's bad enough to cause a recall.
Porsche says it is cooperating in the investigation.
