Jeep Grand Cherokee Problem Report
Jeep Grand Cherokee Engine Will not Start Due to Wireless Control Module Fault
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.
My car wouldn't turn on at certain times. When I took it to Jeep they told me that:
"the reason for your intermittent starting problem is because the WCM (Wireless Control Module) for the vehicle is internally shorted out causing the vehicle to shut down the computers. To fix this problem you would have to replace the WCM. This repair would cost $842 + Tax."
I've come to realize that this is more of a common problem that I anticipating- taking consideration other posts and that my jeep dealership told me the parts were on back order as well. My question, why isn't there a recall?

Intermittent shut down of complete electrical supply - Visitor
My 06 Jeep Commander would not unlock using the wireless key remote...I manually unlocked the car and started it. After driving to the store, I started the car and after 2 seconds, the car shut down automatically. A red dot for the security system alert blinked a couple times on the dash when the key was in the ignition which led me to believe that the problem was the WCM or wireless control module. First get new batteries for your keys; there might be a little screw. After trying new batteries for the keys, DISCONNECT THE BATTERY AND WAIT ABOUT TEN MINUTES; RECONNECT BATTERY AND START CAR. This should at least get you to where you need to go. After disconnecting the battery twice, I tried my keys with the new batteries and everything seems to working properly...Dealers are no fun. - Visitor

No Crank condition, alarms at manual door open - Visitor
This happened to me 2 months ago, so we had the WCM replaced and the key reprogrammed. Well, it just happened again 2 days ago, and they had to reprogram the key AGAIN. We will see if it happens again! - Visitor
I had previous non start issues that the dealer fixed while I wait for the parts from the fuel pump relay recall. A few weeks after the fix the car stalled while I was reversing. This time they are telling me it is the wireless control module and I have to pay $360.00 to replace it. - Visitor
I experienced the exact same problem just two days ago. I was hoping to just get my starter replaced, but unfortunately they diagnosed the problem was more than just that. The wireless control module replacement part plus a new programmed key is going to cost $800. - Visitor
I had all of the same problems and the blower motor fuse was the problem!!! ITs because of the grounding it has - Visitor
When the key is turned to start the car you hear a click and a sound as if the starter would try to engage but the engine will not turn, changed the starter relay and nothing happened, still clicking. After a few tries the GC would start and continue normally. Took it to a repair shop, battery , charging system and starter checks fine. Will continue monitoring. - Formula2
module transmitter failed--exchange part = $392 plus $191 labor--can't even give me a date on when exchange parts come in--could be without vehicle for a week. I I think I am going to trade it in. - Visitor
I could not start my car and through it was a bad battery, I replaced the battery and could still not start my 2008 Jeep Grand Cherokee. I then had the Jeep towed to the Dealership thinking the Key Fob needed to be reset. Nope.....it was the WIN module that needs to be replaced. This is not the first time hearing this could be a problem. I am very angry that I am now paying 800.00 to have the part replace. - MAD2008Jeep
