ORLANDO, Fla. -

Government safety regulators are investigating complaints that Jeep Patriot SUVs are stalling without warning at highway speeds.

The probe by the National Highway Traffic Safety Administration affects about 112,000 Jeep Patriot SUVs from the 2011-2012 model years. 

The Office of Defects Investigation has received 12 complaints alleging incidents of engine stall.  Approximately 10 of those incidents occurred at speeds of 65 miles per hour or more. All complaints reported that the vehicle could not be immediately restarted. 

"The complaints show an apparent increasing trend, with all but three received within the past six months," NHSTA stated.

One complaint alleged that the high-speed engine stall resulted in a crash and injury.

NHTSA says the probe is an preliminary evaluation to assess the scope, frequency and potential safety consequences associated with the alleged defect.
