Vehicle loses power to accelerator at random, unpredictable times (could be at a stop sign, could be while traveling on a highway, and does not matter if car is hot or cold). Warning light (lightning bolt) flashes on the dashboard, and accelerator is sluggish to respond or unresponsive altogether. I have nearly been in two accidents while pulling into traffic because cars starts to go, but then loses power and the accelerator takes about 3-4 seconds to recognize I am stepping on it. I have had it into Chrysler dealership three times now, and they are unable to diagnose the issue. First time the accelerator pedal assembly was replaced. The second time, the pcm module (drivetrain computer/module) was replaced in its entirety. Problem started occurring around 30,000 miles, and has continued since (now at 41,500). Has nearly caused me to be in two bad accidents, which caused other cars to swerve/skid around me because I was stopped broadside in roadway. They would not acknowledge problem until they made me drive them around our city, and prove to them what happens. Luckily it happened while he was in the car with me, but the service techs are unable to diagnose the problem and continue to work with Chrysler engineers to no avail. Other instances include being stopped at a red light on a hill, and not being able to go forward in time, and nearly drifting backwards into vehicles behind me. This requires use of heavy foot on gas and emergency brake. Additionally, vehicle is a 6 speed manual, and sometimes 'pops' out of first gear while starting from a stop position. This issue has happened for the last 5,000 miles approximately but is becoming more common (nearly daily). I believe they will be able to diagnose this issue and correct it (common problem according to my internet research), however it does not appear they have a handle on the first issue. I have been told to leave my vehicle at the dealership until they can diagnose and fix the problem, it's not safe.

I was driving at 55mph and ran over a badly maintained road bump (a 3ft section of pavement spanning both lanes of a 2 lane rd. That had no stone in it to level it off) and my 2007 Jeep 4dr Wrangler unlimited sahara lost engine power. All power options in turn lost power. I managed to pull the Jeep to the side of the road. I turned the key off and attempted to restart it. It started back up with no further incident. This same power loss occurred once before after driving on a wet road on a rainy day. That 2nd occurrence lasted about 1second and then re-powered.

Luckily , there was no other traffic in the area or obstacles in front of me, and I was able to bring the Jeep to a stop in 50 yards or so on a steep down-hill section of road. After bring the Jeep to a stop it started up again without problem. The Jeep dealer said they have not heard of this problem although I have found other's on the web, indicating situations where the engine randomly turned off. This was a major safety issue.

I bought my 2005 Jeep unlimited with 6,000 miles on it. I have been to the dealership seven times to have it fixed. My major complaint is it surges out of control when taking my foot off the brakes from a stopped position. It does it in drive and in reverse without warning. The dealership has no solution. I also have a problem with the steering wheel shaking once I hit a small bump in the road,as small as the reflectors that line the middle of streets. There are times the steering wheel shakes so hard that I have to let go of the steering wheel. They have replaced my steering stabilizer arm,I've had the rotors turned I've replaced the brakes. Replacing the stabilizer arm seemed to help for a short time. My other issue with this lovley death trap of mine is when I run the a/c the whole thing bogs down like I'm pulling an eighteen wheeler out of a ditch. The dealership solution was to come in and test drive another Jeep to see if I "actually have a problem". When I take my car to the dealership they keep it for at least two weeks and the problems are still there. My advice to other Jeep owners with these problems is to always take the back roads and always leave a car length of space all the way around your Jeep, and never use the a/c!these problems began at about 10,000 miles and my Jeep just rolled over32,000 miles.

1998 Jeep Wrangler, 4. 0l. These two issues are on service bulletins, but should be recalls. The first issue occurred as my wife was driving when the valve springs snapped, stopping the car in the middle of the interstate. Discussed in detail on service bulletin 182298, initially issued before I even purchased my car. It was very frustrating to find out that Jeep was aware of such a dangerous issue and did nothing to prevent such failures from occurring. The second is a very widespread and documented problem when the main instrument cluster spontaneously stops working, including the speedometer, odometer, air bag indicator, fuel gage, oil gage, etc. . . Discussed on service bulletins, 081599 I believe. You cannot tell your speed, how much gas you have, etc. . . Another implication is that the odometer is incorrect on many Jeeps.
