jeep liberty 2002 limited
Usually starts fine when left sitting for a while. If restarted after a short trip, it is more difficult to start. More short trips lead to more difficultly starting. Eventually I start it with the gas petal down and white smoke out the exaust. Last night it didn't start then 30 min later started with no problem. Just did an oil change. Didn't replace fuel filter. Haven't checked battery. Any ideas?

I've had the same sort of problem. Every once in a while , regardless if driven everyday or periodically, my Liberty CRD goes into "limp mode". Sometime the engine will just die. The only error code is P0093, which is a "major fuel leak". The thing is, I see no leaks anywhere. My suspicion is that the fuel filter is clogged, but wanted to first see if anyone else had this issue. I have had the fuel line apart, but have always purged the air out very well. Further, I have never had a problem starting or running the car immediately after having the fuel line apart.
 
Interestingly, if the problem occurs, I can resolve by turning off the engine and restarting. I have tried primimg the pump on the filter housing with engine running when the problem occurrs, but it does not resolve the issue.

Finally my husband fixed the problem. We got some info from a member of this forum. He replaced the speed control sensor which he said screws into the passenger side of the engine block. It senses the speed of the engine from a small magnet imbedded in a fly wheel gear. The part was ordered by our mechanic from NAPA auto parts and cost about $25. Have not had a problem since he replaced that part last sept. or oct. Good Luck. Hope this helps anyone else having the same problem.

Stalling Jeeps by slyt1

My 2003 Jeep stalled out several times at stop signs and slow speeds. I replaced a sensor and it worked fine for about a year when it shut off again this time on the HIGHWAY. The RPM dial goes crazy, the steering wheel locks, and it totally dies. Of course, this is a HUGE safety issue. I had the crank sensor replaced after this episode and it worked fine for only 2 weeks, when it again stalled (at about 40 MPH on a city road) and had tons of smoke coming from the exhaust. How is this not a recall? Any suggestions on how to fix it? At this point I would love to sell it and get a different car....none of this was under warranty either.

How is this not a recall?
 
It would be a recall only if there were some real defect. Parts wear out, vehicles need maintenance and some mechanics misdiagnose problems but those are hardly reasons for a recall. I think it's best to find out exactly what the problem is before making an indictment.
 
Perhaps some of the experts would jump in and offer some guidance. Anyone?

from the NHTSA website:
 
NHTSA is authorized to order manufacturers to recall and repair vehicles or items of motor vehicle equipment when ODI investigations indicate that they contain serious safety defects in their design, construction, or performance. ODI also monitors the adequacy of manufacturers' recall campaigns. Before initiating an investigation, ODI carefully reviews the body of consumer complaints and other available data to determine whether a defect trend may exist.
 
so in other words, a breakdown of one car one time, or even one car multiple times, doesn't mean that all or most of that make model have a provable design defect.
 
BTW, the automaker may also voluntarily issue a recall.

Recall issue aside, any advice? by slyt1

The issue is not if it should be a recall or not, regardless it is a huge safety issue. Its now been in the shop 3 days and they cannot figure out what caused this problem. They investigated all the codes and reset them and drove the car to see if it will stall and it runs fine now. I just have to drive it until it stalls again...hopefully not on the highway again.

Intermittent problems are the devil, because you often can't fix it until it happens, but when it happens there's no one around to fix it.
 
it could also be that their scanning equipment isn't sophisticated enough---not all are created equal. Or it could be a computer glitch, which is a real pain to track down.
 
No easy answers with an intermittent problem, sometimes you just have to take your best guess or find someone with the patience of a saint and the genius of Sherlock Holmes to track it down inch by inch, component by component, testing each one for proper values---which isn't cheap.
 
I spent 6 months off and on on a Jeep once before I found the problem.
