The National Highway Traffic Safety Administration opened an investigation into the matter last summer that could have led to the recall of 1.86 million Dodge Caravan, Dodge Grand Caravan, Chrysler Town & County and Chrysler Voyager minivans from the 2003-07 model years.

No crashes or injuries related to this issue have been reported, the safety agency said in a report on its website.

"The stalls occurring in these vehicles only occur immediately after filling up the fuel tank and happen at low engine speeds," NHTSA said. "The failure rate is low."
