#642 of 731 some jeeps sluggish and some not.
Feb 08, 2011 (3:20 am)
Hello, I recently purchased a 2008 grand Cherokee 4x4 Laredo. I noticed that it is very sluggish. It takes a lot of effort to accelerate the vehicle. About a week later I had to drive a loaner car while I had something fixed. The loaner car was the exact same model just 2 years older. It was 2 identical cars but the loaner car was not sluggish at all. If you step lightly on the has the car would move fast. Why the difference?

Sorry for the delayed update.. I finally met with Chrysler west coast dealer rep and engineer who went for several rides and recorded data on the engine performance. Bottom line is that the hesitation / fluttering is not the engine according to the test results. Instead, they "believe" it may be a bad torque converter that is causing the problem. I'm scheduled to have that part replaced later this week. The saga continues....

i have had the same problem. I bought my jeep in august, had about 30000 miles i got extended warranty i had it three months when it started to act up. it would not start and had the trans over temp message. then it worked fine. one day it would not. had it towed and dealer said it was starter. worked fine for 3 more months. it did it again on thursday but started. worked fine sunday and would not start sunday night. had it towed again, the dealer now said it is a module that will cost me $650 because it is not covered under the warranty i purchased. i now have 35500 miles on it.

I also have a terrible "hesitation" in my 2011 GJC. Its was manufactured 8/10, and I've now taken it in twice and the dealer insures me they have updated it for the flash update. It still does the exact same thing... low speed hesitation and then a quick surge. Pretty sad, especially in snow or wet conditions. Has anyone had any luck with a fix?
#647 of 731 Re: Jeep white smoke from tailpipe [bill202]

Did you ever see any smoke/steam from the tailpipe, or signs of oil leaking from underneath the engine area? I've read that smoke/steam is a sure sign of a headgasket problem. However, I haven't seen any smoke/steam from my tailpipe, but there is some oil coming from somewhere. I also found a crack in my radiator.
#648 of 731 Delay in oil pressure
Mar 16, 2011 (9:29 pm)
2001 Grand Cherokee 67,000 miles. Florida so really cold weather not an issue. Oil and filter always changed on time
If parked on a slight hill with engine end of the vehicle down-hill there is a with 20-30 second delay in rise of oil pressure after starting the vehicle. Guage sits on ZERO and check engine guage lite comes on--no engine noises. Then guage goes up to proper level but sometimes all the way to the highest measurement of the guage (80). Jeep has never done this before. I am concerned about the relatively ling time the engine runs with no oil pressure registering on guage. OIL dipstick after last oil change slightly above full level on level ground with engine cold--Oil change place say this slight over fill is not a problem
Does not do this when parked on level ground
#649 of 731 98 Cherokee Sport bucks and lurches
Apr 01, 2011 (7:51 am)
Hi Guys. I've got a question for the mechanical geniuses.
My 98 Cherokee Sport hesitates when I back it up. It also starts lurching and bucking on the highway after it's been running for a while. Lastly, it backfires internally if you try to start it up but don't turn the key to the on position for about 30 seconds ahead of time.
Any ideas what could be going on? I'm planning a trip cross-country in May and obviously can't take it running like this. I live in a small town and the only "mechanic" within a reasonable drive is a backyard guy.
Thanks a lot.
#650 of 731 #7 Cylinder Code Miss
Apr 05, 2011 (7:38 pm)
Having problems with my daughters 03 Grand Cherokee 4.7 HO. A few months ago, it would just stop running. Ended up replacing the cam and crank sensor. The engine continued to run rough. Ended up having a #7 cylinder miss fire. Replaced the spark plugs and all was good. Now it came back on the #7 cylinder. Switched coils around and still continued to run bad. The #7 spark plug didn't look bad or smell bad like it wasn't firing cause of spark, but maybe no gas???????
