Chrysler's uncooperative stance over a National Highway Traffic Safety Administration (NHTSA) request to recall around 2.7m 1993-2004 model year Jeep Grand Cherokees and 2002-2007 model year Liberty vehicles is unusual and leaves owners in "limbo", according to Edmunds.com.

Senior analyst Michelle Krebs said: "Chrysler must feel like it has a compelling reason to take such a bold stand. Since Toyota was publicly humiliated for dragging its feet on recalls just a few years ago, automakers have been quick to recall vehicles at NHTSA's request.

"Unfortunately, consumers with problematic Jeeps are in limbo. They will have to wait for the process to play out."
