An Elkhart maker of electric cars has issued its third recall in six weeks.

The Elkhart Truth reported Wednesday that Think North America has filed documents with the National Highway Traffic Safety Administration recalling 23 of its City electric cars produced late last year after one dealer and two owners reported the vehicles had rolled forward when the gearshift was in the park position.

The cars, assembled in Elkhart from Dec. 8 to Dec. 22, were found to have improperly adjusted gear-shift levers, the company said.

Company spokesman Brendan Prebo said all of the affected cars have been inspected and serviced.

Two previous recalls on the same 23 vehicles addressed seat belt and defroster problems.

Think began producing its very first vehicles in December. The Norwegian company sent 15 cars to Indianapolis, where they're being used primarily by the Indiana Department of Natural Resources as part of its fleet of vehicles.

The company plans for the new factory to produce 2,500 autos per year initially and employ 415 people by 2013.

The Think City is made with recyclable plastic body panels and can travel more than 100 miles per charge.
