The National Highway Traffic Safety Administration (NHTSA) has opened defect investigations into two SUVs: the 2002 Jeep Grand Cherokee and the 2001 Acura MDX.
NHTSA is looking into alleged problems with the cooling fan in the Grand Cherokee after four owners claim that pieces of the broken fan blade cut through a plastic casing around it. The investigation involves approximately 132,000 Grand Cherokees with 4.0-liter engines.
NHTSA reported it is also looking into complaints of front coil springs breaking in the Acura MDX and contacting the tire. There have been no injuries or crashes reported from the alleged defects.
