HI PLEASE DID YOU EVER FIND OUT WHAT WAS WRONG WITH YOUR JEEP??? I NEED HELP!!!
 
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!!!

My jeep does the same thing and I can't get my factory wired trailer hitch to work on the running lights. If I turn on my fog lamps my headlights go out and when I turn on my headlights they flash and people think I am flashing at them even in the daytime. HELP

Did you ever find someone that knew what to fix with your headlights? Mine did the same thing last week while driving 80 passing a semi at night. The dealership doesn't know what to do....

Sounds like we had a different problem. We never had a problem with our head lights our jeep was cutting off completely while driving. We had to replace the power control module it cost almost 900. Have they checked your batter and altinator? Sorry i cant be more of a help.

I have not been able to find out the issue and it sounds like there's no clear solution. I agree w/ busymom - it's terrifying when this happens at night!

Hi back again! The problem still is going. I took the Jeep to a dealership. First I spent 338.00 and drove the Jeep 10 miles. It quit working. The engine will start then die. So this is what I'm being told. I replaced the BCM with one from a wrecking yard. New wasn't available. The dealership says that the BCM that we put in is shutting down the PCM and the only way to clear the problem is to buy new BCM and PCM and have them installed. I have all ready put 1100.00 into the Jeep. Now with the new amount with tax it will be up to 2700.00. I am at a loss. Why can't they clear the PCM and the BCM and start over? Program them to my car? Why do I have to buy new ones? Please someone technical HELP!!
