#141 of 159 PCM Module Out of Stock by talkjeep

One month ago, my 2005 Jeep Grand Cherokee would not turnover to start. Had it towed to local jeep dealership. Diagnosed as a bad Power Train Control Module, to be replaced under warranty. Part has been on backorder for one month without any restocking date from "their vendor." Told by their Parts Dept that there are 43 other customers nationwide awaiting this after market part. They have no idea when it will be restocked. Fought for 2 weeks to get them to pay for a loaner/rental car. They OK'd and are paying for a stripped down Dodge Nitro that is a back killer to drive. Every week I call - they say there is NO RESTOCK DATE. I offered to let them keep my jeep as a trade in at Kelly Blue Book trade in value, plus the cash difference that I could afford to buy a new 2011 JGC with the comparable upgrades. They wouldn't accept my offer (a few thousand shy of their bottom line). My two questions:
 
1. What are my rights (their obligations) since they are not honoring their warranty; they can't tell me when, if ever, they will be able to get the PCM Module to replace it; and I can't use the car in its inoperable condition as a trade-in on any other makes if I choose not to buy another jeep???? Note: the Jeep District Manager refuses to meet with me to discuss the situation.
2. At this point, if they can't get the part, and since no one at Chrysler corporate will help, how can I get them to buy me out at the Kelly Blue Book trade in value so I can shop for another vehicle make?

talkjeep....I hear you...I am so frustrated with my Jeep GC 94. I am on my 4th PCM. I love my Jeep and have from the minute i saw and bought it used 10 yrs ago....I cant begin to explain how angry I have been when ever the PCM has failed. Im not positive but it seems alot of the issues have been caused by an electrical short somewhere. In my case it apparently was the wiring harness in the drivers front door and it doesnt take much of a short to cause the PCMs to get fried. I too would like to be rid of the problems, but finances wont allow so I have to gamble on yet another PCM. I wish there was some legal way to have Chrysler go good for all this mayhem....As you know by the apparent runaround that you have been through, the dealers(or most of them) are terrible at looking after honest customers. I wonder how many of us there are.??!! to all of us going or gone through this...good luck!!

My 2003 JGC power windows and locks will not work only when it is below freezing. After the vehicle warms up they work fine. When you work the switch there is not even any sound from a motor. Nothing. Anybody have this problem or know what to check or how to fix it?

Hi Jeff,
 
Hopefully you are still on this site. I have major problems with my 2001 JEEP Grand Cherokee. It first started a few months ago while driving, the JEEP would jolt as though it was trying to cut off. After a month of that it did start cutting off while driving and at stop signs/lights. I would have to put the car into neutral and restart- while driving!!! After about 2 months of this it would not start easily, or it would start and cut off within 10 seconds. After this it totally died and I had to replace the battery. So, after I replaced the battery the JEEP started, but still with the same problems listed above. Additionally, there are other things going on that I believe are related: the speedometer fluctuates up and down, the digital gas reading fluctuates- it will say 100 miles to empty then 0 miles to empty then 24 miles to empty and so on. Not sure if these are all related. Additionally, I had the altinator tested and it was 13.5 (kind of low).
 
The dealership ran diagnostics, but couldn't get a reading because they said "it would fix itself and no codes would come up."
 
Now they are telling me to replace the PCM. They want $900 total! I have already put so much into this JEEP to no avail. After reading some of these posts I am wondering if it may just be a coil? Please help. I need to know what questions to ask these jokers- like did they test for spark??? Please give me some ideas and maybe a list of questions to ask the dealer to see what they did to determine that it is the PCM.
 
Thanks!!!

I'm here. But fortunately for you, lots of people with experience fixing Jeeps are here too.
 
Checking the battery connections everywhere, including the firewall or wherever they terminate may help. But I'm no mechanic.

#149 of 159 First and last for me...unfortunate by grizz4

Jul 11, 2011 (5:51 pm)

Bought a used ( around 53,000K) 2005 Jeep Grand Cherokeeoff at a lot, have just over a 100k on it now and had nothing but problems. Everything from hard downshift at around 40kmh (have had transmission flashed twice now), wiring failing to rear passenger side window, rear seal on driver side leaking and now the lights, dash and (rear included as are trailer plug) are flickering and acting "possesed". Very obvious this vehicle has many flaws that are common to all of this year and more...yet the buyer of them has to foot the bill instead of a "Great" north american vehicle manufacturer stepping up and admitting problems and fixing them as a responsible manufacturer should....warranty or not. For the money this vehicle was brand new on lot ( just over $45k) and only being 6 years old I am blown away by the "North American Heep" it is...is it any wonder why people buy import?? And I have spent thousands more on this vehicle then I did on my Mazda MPV (2003) which I retired only because I had put over 200k on it and the only thing other than regular maintenance (brakes, engine oil and transmission oil service) that needed done in that time was a repack of a front wheel hub! Sorry Chrysler/Jeep I will never buy another and I love telling people about my 2005 "Heep"!! If I detour one purchase of this vehicle I will be a much happier man...but honestly I think it may be more
