Chrysler Group is expanding a previous safety recall “out of an abundance of caution” to correct ignition switches in minivans and SUVs.

The automaker said today that it wants to install a more robust WIN module detent ring.

A previous recall in 2010 included 196,000 Chrysler Town & Country, Dodge Grand Caravan and Dodge Journey vehicles built Aug. 2, 2009 through June 17, 2010.

Today’s expansion includes an additional 695,957 vehicles manufactured on Jan. 29, 2007 through Aug. 1, 2009.

Chrysler indicated vehicles equipped with a FOB key may experience inadvertent ignition switch displacement from the “run” to “accessory” position while driving.

“If the switch is not fully engaged in the ‘on’ position of the detent ring inside the module, the spring-loaded switch may allow the key to spring past the ‘on’ position and into the ‘accessory’ position,” OEM officials said.

“This action will shut off the engine and passive restraint systems, including air bags,” they continued.

Chrysler noted the issue was originally identified through the company’s internal quality control research and customer input.

“Chrysler Group is unaware of any injuries related to the expansion,” the automaker said.

The OEM said its franchised dealers will, at no cost to customers, install the new WIN detent ring in affected vehicles.

Chrysler added that it will contact affected customers and advise them when service is available.

An estimated 525,206 vehicles are located in the U.S. while another 102,892 units are in Canada. The company said 25,591 units are in Mexico and 42,268 are outside the NAFTA region.
