Safety regulators in the U.S. have opened an investigation into 160,000 Dodge Caravan minivans after receiving reports of engine stalling.

The National Highway Traffic Safety Administration said on Tuesday that its Office of Defects Investigation is assessing "the scope, frequency and safety consequences" of alleged engine stalling after refueling in select Chrysler vans.

"(We) will actively support NHTSA's efforts to investigate" the claims, adding that the agency's investigation notice "cites no injuries or accidents related to this reported condition," said a spokesman for Chrysler Group, a unit of Fiat SpA in a statement to Reuters.

NHTSA has received eight complaints from consumers related to the problem so far.

One complaint posted on the agency's website in July referred to an incident back in June where "my wife (with kids in car) stalled on the highway" while driving in a 2007 Grand Caravan. "She was on a turn and the steering wheel became impossible for her to turn," the complaint said.

Another complaint posted in February reads "vehicle stalls immediately after filling gas tank" and that the stalling "has happened repeatedly in traffic.

NHTSA has received a number of complaints about the same issue on its Chrysler Town & Country, a companion model to the Grand Caravan.

At least 20 complaints have been sent about the 2004 Town & Country, and 25 complaints on the 2005 Town & Country, according to Reuters.

Chrysler engineers will work with NHTSA on the probe, the company said in a statement to the Associated Press.
