Model Years Affected: 2006, 2007, 2008, 2009, 2010

Average Mileage: 70,283 mi (16,000 mi - 120,591 mi)

Verified

If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.

  • this is known problem ,you must use the spare chiped key, alternate use, the chip loses memory. dodge does not know why this is happenning.

    Same problem here! It's happened three times so far latest one yesterday 3/1/2011. After owning 4 Dodge trucks and our local Dodge dealer closing down this is the last one I'll ever own. Closest dealer is 122 miles away, truck went for repairs to this dealer last week for a different problem; coil igniter failed causing missfire to cylinder# 6, messed up two spark plugs, had to go get it at my own expense. Sorry Dodge!

    They've replace the wcm 3 time and still have to remove battery cable and reset. All I get is clicks when trying to start, the red light flashing no dome light. I know it won't start if there is no dome lights come on.

    Stopped at the Post Office. Got back in and turned the key....nothing. Radio and lights worked. Came home and read this thread, went back and disconnected the negative battery terminal. Waited a minute and hooked it back up, turned the key and Wahoo! It started up again. Thanks so much for the solution here!! :)
