#392 of 731 Re: Grand Cherokee drove into cement wall - help [jgc5]
Jun 11, 2008 (5:11 pm)
Sorry. One more time: I have a 2001 JGC with 93000 well cared for miles on it.
The other day I was parking in a parking structure & easing forward into the space, when the throttle opened wide. The jeep jumped forward and crashed into the cement support pillar in front of me before I could do anything. Damage is about $5K.
This has happened twice before (same conditions..easing forward into a parking space) but the first two times I was able to stop. I couldn't track it down because it didn't happen again. This time was worse. Had I been in either parking space adjacent to me I'm sure I would have bolted through the retaining wall and hit the street below. If someone were in front of me, they'd still be scraping them off the wall. I found all sorts of references to this on the web but the local dealer says they aren't aware of a fix (though they were of the problem). No recalls listed either.
The only thing I can figure is the throttle position sensor - or the computer - someone is sending the signal to race when I am parking. Anyone know of this??
#393 of 731 2001 JGC stalling and OBDII light on
Jun 28, 2008 (12:21 pm)
I also have a 2001 JGC V8 and for the past 3 weeks the OBDII light (I think thats what its called) has lit up on and off, and the car has stalled about 10 times while at stopped or going very slow. It goes right back on when I start it up again. It has also shaked violently back and forth while accelerating. The manual says it might have something to do with a loose gas cap or bad gas, but it has been through several tanks of gas now and the fuel cap is not loose. I do notice that when I open the gas cap I used to hear air escaping, but I don't anymore.
So I got an oil change, they check all the fluids, I replaced the air filter, and then had the Auto Zone guy plug in his computer and it said I had 4 issues, all relating to the crank sensor. Just today I bought a $45 crank sensor but haven't had it put in yet.
If anyone else has had this problem or thinks they know what it is let me know please! thanks
#394 of 731 '07 Grand Cherokee - EMC/vehicle computer issues??
Jun 30, 2008 (7:12 am)
Has anyone else had this problem?? Traveling at 65 mph, lightly took my foot off of the accelerator and the car totally shut down, leaving me no control - happened to me 3 times on an 8 hr. drive 2 weeks ago (car has 20,000 miles - all service performed by dealer) - immediately brought the car to a dealer & was told that the dealers had received a service bulletin describing this issue, but no recall was going out - I was told it was a malfunction of the on board computer program and I needed to have the program updated and reloaded - once completed should have no further problems - EXCEPT, the same darn thing happened to me yesterday - traveling back home on a major road (50 mph this time) and same thing occurred twice - slightly took my foot off the gas and the car completely shut down - Does anyone have a copy of the Dealer Bulletin about this? I've reported this to safercars.gov - anyplace else I can go? Just want to get rid of this hunk of junk pronto!!! Thanks for comments!
#395 of 731 01 JGC dies after starting & backing out of driveway
Jun 30, 2008 (10:44 am)
After being parked for 4-6 hrs it will start just fine, but as soon as I hit reverse, & drive out it will die- I have to put it in park and re-start it again. The dealer has kept it for days and tells me it never happened to them, and they cannot determine what it could be. It has also started making a loud "Cracking" noise, when I turn, go in reverse, I am so frustrated... HELP PLEASE.

after my episode with sudden accleration and the concrete wall, I'm in the mode for another vehicle. I went and looked at an 05 GCJ and really like it but am afraid I can't buy another jeep after all I continue to read. It could have ended differently for me with my collision....I don't want to take the chance with my family, or letting one of my family drive.
a real shame

Ok this is very strange I have a 4.7 V8 I can start my Jeep it will run perfect for 1 hour to 2 days then it will miss, back fire I let it sit for 3 hours and it will run perfect for about 1/2 to 3/4 of hour perfect then start missing and back firing again If I let it sit over night then it will run perfect 1 hour to 2 days????? I had the timing belts changed which as you know requires removing the whole front clip I'm not exaggerating by much replaced every sensor on the engine, catalytic converter, all of the coil packs, plugs, fuel filter which cost 90 bucks. Has anybody had to deal with this same problem?

UPDATE: Car is running perfect now for a week. Bought a $45 crank sensor at AutoZone, local garage put it in for $75. No more warning light, no more stalling.
#400 of 731 Engine miss at high 70mph under load.
Jul 16, 2008 (9:54 pm)
I recently changed my spark plugs on my 1999 Jeep Grand Cherokee 4x4, 4.7v8. I have started to get a miss at high speeds. Gas mileage has gotten poor. Local mechanic says transfer case. I think bad coil plug. No codes shown when tested twice though. Any ideas?
