MSNBC.COM - U.S. safety regulators have opened defect investigations into Chrysler Group LLC's 2012 Jeep Grand Cherokee and 2009-2010 Dodge Ram 1500.
The National Highway Traffic Safety Administration said it is investigating potential power steering hose failures that could lead to under-hood fires in about 106,800 2012 Grand Cherokees.
NHTSA also is investing potential rear differential failures that could lead to rear wheel lock-up and loss of vehicle control in about 230,000 2009-2010 Dodge Ram 1500 pickups.
A NHTSA defect investigation is often a prelude to a vehicle safety recall.
NHTSA's Office of Defect Investigation said the power steering hose
on the 2012 Grand Cherokee could fail, resulting in power steering fluid
leakage in the engine compartment. It said the fluid "may be ignited by
hot surfaces in the engine compartment." click here to read more
