2011 Jeep Patriot

After receiving a dozen complaints about stalling Jeep Patriots, the National Highway Traffic Safety Administration has decided to launch a formal investigation. The probe will look at about 112,000 Patriots from the 2011 and 2012 model years.

NHTSA says some owners report their vehicles' engines are completely shutting off at speeds above 65 mph. In at least eight cases, the drivers could not restart the vehicle, and in at least one incident, the stall involved a crash that injured two people.

If the investigation turns up enough cases, the agency will issue a recall of the vehicles. A Jeep spokesman said the company is looking into the issue.
