Engine Will not Start Due to Wireless Control Module Fault on Jeep Grand Cherokee

Problem Description and Possible Solution

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?

Very much annoyed
Lights windows dash lights key remote works but engine wont start
CHANGED THE MULTIFUNCTION SWITCH-STARTED THE JEEP TO MAKE SURE THAT IT WORKED PROPERLY-TURNED IT OFF-GOT OUT & LOCKED THE JEEP USING THE REMOTE--NEXT DAY-THE REMOTE WOULD NOT UNLOCK THE DOORS SO I USED THE KEY-PUT THE KEY IN SWITCH & NOTHING-NO HORN-NO LIGHTS-NO START-NO NOTHING--FULL CHARGE ON BATTERY-CHECKED EVERY FUSE IN DASH & UNDER THE HOOD-ALL GOOD..CAN ANYONE HELP??? BY THE WAY-THE KEY IN THE DOOR THING DOES NOT WORK EITHER!!!
Four times my 2010 Jeep Grand Cherokee LTD has failed to start. When the key is engaged all of the lights "light", but it won't start. I've had AAA tow it to the same shop 4x since December of 2014. We've replaced the starter because the mechanic thought it might have a "dead" spot. It happened again.. When it got to the shop - it started every time, no problem. On January 9th it happened again and it was towed to the mechanic - it started while at the shop.. every time and they drove if for the weekend w/o a problem.. again a month later it was back in the shop.. where I had the key's re-flashed. It wouldn't start last Tuesday, towed again. Now its at the dealer's being evaluated for a faulty ignition module.
The remote functions of my key fobs work intermittently .
changed the batteries but that made no difference.
I had this happen to me 2 times in 7 months my jeep would not start at all we come to fine out in in the wireless control module (WCM) so i now it is starting but well need to get it fix my boyfriend it the dash below the key and it it started I hope this helps
I had all of the same problems and the blower motor fuse was the problem!!! ITs because of the grounding it has
No Crank condition, alarms at manual door open
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.
Jeep replaced the key fob and ignition under P57 recall. Now I cannot use remote start....augh!
Same as others have written. First started about a month ago when I turned off the ignition & pulled out the fob, but jeep kept running!!! Then got it shut down & wouldn't start, message "damaged key". At dealers for fix "out of warrant of course". Initial estimate $700 + another $280 for fancy glass filled battery!!! asked if battery was dead, or if it could be charged....apparently it's not that the battery is dead, just gives the code that it's dead! Dealer is gonna put old battery in & see if it still cranks!!! German engineering folks!!!
Never know when it will start...usually does not...two different garages say there is nothing wrong...neighbor said it might be the WCM...this site is informative in that I now own a very expensive lawn ornament!
I have had my 2005 Jeep in for this 3 times. The key works sometimes and other times it doesn't and when I use my key in the door, the alarm goes off. I wish the dealership could correctly diagnose my problem, so I don't have to take off from work and go back and forth. I did have another key made and it was 235.00 to get it cut and programed, but it still doesn't work right now. Every time this happens I crank it up, then the alarm is going off and lights are flashing, people are staring and pointing at me as if I am a thief and stealing a car.
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.
At any random time my 2008 Jeep Grand Cherokee Laredo will not start. The battery is new. Lights come on, radio comes on, lights do not dim, but jeep will not start. After waiting and trying again it starts up fine. It happened twice within a month. Had it checked, issue couldn't be found. Happened again and was almost stranded in the snow so got new starter. Issue still happens and is happening more frequently.
This is the 3rd time this has happened since I purchased the car new. It is very frustrating!
Runs fine and then I will get in and it won't turn over. Let it set and normally it will work next day. Have had it in the shop twice now. 1st time they couldn't get it to do it at all so they replaced a recalled part from before. Had it towed to them the next time so they could see the problem - still didn't see it - replaced the batteries in my key fobs. Today won't start again!!!!
Intermittent shut down of complete electrical supply
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!
Intermittent no start. GC would start using remote but then the key would not be recognized by ignition. Dealer says WCM. Estimate is $800.
