Jeep Liberty Starting and Stalling Problems



  • kim22kim22 Posts: 4
    It is disturbing that so many other people are having this problem because it makes me think that there is some larger issue with the Jeep Liberty. Oh well, I guess time will tell. For now, my Jeep is working. It has been about a week since they replaced the battery and belt tensioner and so far, so good. However, my dealer used the same logic as your dealer. They were not sure that this was the problem, but thought that it might be. If anything else happens I’ll send an update. I hope others do the same and maybe we’ll get to the bottom of this.
  • Dear All,

    Wife came home this evening and Liberty will not start. There is a "strange" sound coming from the locking mechanism for the rear gate and window. It has a continous "click click click" like it is trying to unlock. Also, the rear light in the beack of the car on the inside goes on and of repeatedly. Nothing on the keyfob works - no door lock, unlock, security etc. When the doors are open, nothing works, it appears that there is no power at all.

    Any thoughts or suggestions would be appreciated.

    You could check the battery connections first, then turn on the headlights and see how they glow. This will tell you the condition of the battery. If you still have the clicking sound disconnect the battery for a few minutes, reconnect and try again. This will check your ECU. Next step is to call a cab :sick:
  • Hey Everyone,I am a mechanic at Cino Auto Repair in Stoney Creek. I had quite a time figuring out this p0320. I went through the diagnostics and it told me to change the Crank Sensor. I did that The Jeep ran great for about 20 Minutes and began to stall again. The Jeep also ran like a bag.. I then proceeded to change the cam sensor no change... I tried rewiring the sensors... nothing I then tried dropping the exhaust behind the y-pipe no luck... I thought for sure it had to be the computer but before that I thought I would try one more thing. I dropped the front two cats off the manifold sure enough that was the problem... The front two cats were plugged. Nicely they are still under warranty

  • Please see original post #57...try cleaning the throttle body first before you do anything. I know it seems like a rudimentary fix, but instead of throwing hundreds of $'s at this problem (which is not all that uncommon based upon other forums where people have gone to extremes to fix this problem - see links on #57) I would opt to try the $7 fix first. ALthough we no longer have the Jeep (royally frustrated, had to sell), the next few weeks we had it, it never stalled after cleaning the throttle body.
    You see, every time your vehicle stalls in this new age of computerized vehicles, it throws all of these "fault codes". The engine stops prematurely, and the CAM/Crank sensors fire because this is not natural for an engine to do this. You take it to a dealer, they hook it up to a machine and say, "well, we see that error code p0320 has registered, must be your Cam/Crank/etc sensor." Then, you start throwing money into replacing things that don't fix the problem. Next time it stalls you'll get the same or another error code all because your throttle body is dirty, less air gets through and your Jeep stalls. This is partly due to higher emissions standards since some of the exhaust, full of carbon deposits, is directing back through your throttle body to be reburned. These deposits build up, limiting air flow, and the Jeep stalls out. If it was a Cam/Crank/etc sensor, how come this only happens when you are stopped/idling? I think that if the sensor was bad, this would happen while driving at higher speeds (although in other forums this has happened as well). It also makes sense that this does not typically happen at higher speeds because more air if flowing around the engine thru the air filter and into your intake. This was something that a high school auto tech program was able to diagnose/fix. The teacher was a former Ford master-tech, and was willing to replace the $75-100ish sensors at cost (i.e. no labor - since my wife taught there), but first opted to do the minimal/cheapest fix first (clean out the throttle body), which ultimately worked, at least for the next few weeks we owned it.
    Dealers and garages get paid more to fix the more complicated items based on a standardized chart. Cam sensor = 2 hours labor (probably takes them 20 minutes + 10 minute test drive) which = more money, let alone the mark-up on the parts. The guy we went to gets paid a flat salary to teach high school students in their auto-tech program. Cleaning the throttle body is probably less than 1 hour and something that, if you have the tools and have minimal auto repair skills, you could probably do on your own. Disconnect the air intake, remove the throttle body, spray with cleaner from Autozone/NAPA/Advance Auto Part or wherever ($7) and put back together. This mechanic said that our throttle body was filthy @ 50K miles.
    I must admit though, we did sell the Jeep after only a few more weeks/months of this fix, but it never stalled after that (prior to this it was almost a daily occurance). Replacing sensors, computers, wiring, other major components will make NO difference if the vehicle is not getting the air it needs. The only thing I found wierd about this was that I drove a truck 107K miles and never had this problem, but that it does seem to be a common theme amongst Jeeps, particularly the Liberty. Perhaps poor design on Jeeps part in the older Liberty's. Don't know how the new ones drive, and probably never will, but maybe they fixed the problem now that they have a new "Unlimited" powertrain warranty (that I'm sure is not transferrablee after 3y/36k is up, and even more likely will be denied if on one occassion you went >3K miles before an oil change, or can't provide "documentation" of maintainnance) - should be on them to fix this now instead of the consumer. Hope this helps
  • HEY! We just had this problem yesterday. EXACT problem. Did you ever figure out what it was from?
  • I am having the SAME problem! (2006 Jeep Liberty Diesel <23K miles)

    I am a single mom and this is the LAST thing I need! :(

    I just ran to the store (a little more than across the street from where I live) and it stalled once going over there and about 3 or 4 times coming back. It acted like it was getting no fuel whatsoever. When it would start back up, it would NOT move. I took it to the dealer a couple weeks ago because I had another recall on it. When I got there, they said there were actually THREE more recalls. They said (one of them) should fix my "problem". Well, obviously it didn't.

  • Hey, man...I got the stalling problem. It's been in the shop for three weeks. They wanna replace all three Catalytic converters. I'm thinkin I can do that myself. Did replacing the cats work out for you in the end? They already replaced the p0320 thingy....speed sensor. Nothing, I havn't even had it three months.(03' 85,000)

    Hrlp a brotha out!

    I had the same problem a couple of months ago and I believe it turned out to be the solenoid that releases the real glass. Apparently its either damaged or just worn out to the point that it was causing a constant 12 volt draw which ravaged the battery to the point of no recovery, on top of that I think my radio got damaged because it power cycles just about every 30 secods, I don't loose any settings or the clock but if I am playing a cd the whole cd will start over from the beginning. That problem actually happened to me twice I have an 02 liberty sport.
  • I had the same problem, the dign test came back and said it was the speed sensor so I replaced it and the problem still there. My check engine, ebrake, and anti-lock brake lights are on. Has anybody solved this problem yet?
  • xtecxtec Posts: 354
    If you already had the code read and it said to replace the sensor,you either have to clear the code,or after so many starts or miles your light should go out.
  • Hi rich14. Did you every find out what was wrong with your Liberty? re: I'm having the same exact problem.

  • rich14: Any answers yet. I have a jeep liberty did the same thing to me stalled going down the road and the tach went crazy. I didn't have the smoke or gas smell. but had the other symptoms. :confuse:
  • I bought a 2007 Liberty, just had it less than 2 weeks, it was a 3 month corporate lease. So I did buy it used, about 5K miles on it now. Been running ok so far, except for below issues. Any suggestions.
    1. Today, backing into my parking space it stalled? Started up fine and ran fine, so I shut it down and came into work.

    2. At times I feel a slip, especially when I decend on a road with a slow grade, wasn't sure if it was just the automatic, I don't normally drive automatics, and its been long time since I drove a 4wheel/Rear wheel car. Feels like the tranny or rear end is in spin up, then grabs slightly, kind like when you coast down a hill in a manual shift then let the clutch pedal out.

    The deal said it's still under the 3/36K warranty, and I was actually thinking of buy the extended before I hit the 12K to avoid additional charges.

    Any ideas on this transmission feel, or the stalling out when backing up?

    Any help would be greatly appreciated.
  • I own a 2003 Jeep Liberty that has recently began stalling when I stop. The check engine light does not come on. Did anyone ever figure out why this is happening?
  • scp301scp301 Posts: 2
    I own a 2003 Jeep Liberty Renegade with 78000 miles. I recently encountered the same stalling problem that most people seem to be having in here. After about 10-20 minutes of running the engine would stall out. This would happen whenever I slowed to a stop or the engine idled. The engine light turned on and I got the code p0320. After reviewing all of the posts in this forum I decided to try a couple things before taking it in. I cleaned out the throttle body with a carb cleaner. It was really easy to do. I just took off the air duct to the throttle intake, opened up the throttle and sprayed down the inside walls of the body with the cleaner a few times. I also replaced both the cam and crank position sensors. They're pretty easy to replace if you know where they are and only cost about $20 a piece at autozone. Although, it took me a while to get the old crank sensor out. It was a bit corroded, which caused it to seize up. In any case, I'm on day two and the jeep seems to be running fine. I live in chicago and have about a 35 mile commute with plenty of stops every day, so if the problem still existed I'm sure I would have encountered it by now. Oh and the check engine light turned off after the first day of driving. Unfortunately, I did a couple of things at once, so I can't tell you which one actually fixed the stalling. I would definitely recommend cleaning out the throttle body first before replacing the sensors. Mine was filthy. To make a long story short, by trying a couple fixes on my own I saved myself at least a couple hundred dollars the dealer would have charged me for the same work. Hope this helps anyone else with this frustrating problem.

    My advice to anyone owning a Jeep Liberty - get rid of it - just take the loss and trade it in for anything but a Jeep. I did. I had purchased a brand new 2006 Jeep Liberty (which I had wanted for some time) and it was a 2 year nightmare. Every month something went wrong with it in addition to the starting/stalling or just not starting at all issue.
  • nikjeepnikjeep Posts: 1
    Im having trouble with finding the crankshaft sensor can any of you tell me where its located on the jeep liberty?
  • scp301scp301 Posts: 2
    It's on the bottom side of the engine. You can't see it from the top side when you open the hood. You have to get below the car to access it. I reached it by sliding under the car from behind the right front tire. Facing front, it's on the bottom right side towards the rear of the engine.
  • ervinoervino Posts: 1
    I had a similar problem on my 03 Liberty. It just died and would not start. After many days, they determined a faulty crank sensor burned out all coils. They replaced the sensor and six coils and seems to be fine.
  • ghardy19ghardy19 Posts: 2
    I use my Jeep to deliver News paper where I live every day for the last two years (about 115 miles a day) and never had a problem until the 12th of this month then halfway through the route the Jeep just died. The first couple of times it started right up and I was able to drive a few miles but after a while it would stall and it was harder to start and I could drive only a few hundred feet and stop. I noticed the tach would do it's little dance. One time it went to 7grand and I had no power. It took me about 3hours to drive 20 miles home. I let it sit for about a hour and it started right up but ran rough, black smoke was comming out of the tail pipe and you could smell gas.. Used a hand scanner on it and found a code p0725. (Engine speed sensor malfunction) Monday I brought it to a Dealership and they told me I needed a PCM and Cam & Crackshaft sensor. The cost almost $1800.00. I read this forum the night before and knew most likely the PCM was good and they justed wanted to make money off me. I told them to get bent and brought to a local garage and ask them to replace my cam and crankshaft sensor. It took them 30 min. and it was running like a champ. They were not sure if it was going to work but after a week and almost 1000 miles I have not had a problem. I almost forgot I have 128,000 on my jeep and still going strong. :shades:

    hi my name is shonn and i have a question for you.i have a 99 jeep cherokee.a code came up,p1391.its getting spark,and its getting fuel too.i need to know do the tone wheel have anything to do with it? :mad:
  • rashawrashaw Posts: 2
    We recently had similar behavior. There is another post on this site that explains the issue and the fix. That post stated he replaced the cam shaft position sensor and the crank shaft position sensor and cleaned the throttle body. That trio cured the problem but he wasn't sure which one. I replaced the cam shaft position sensor today on ours and that did NOT cure the problem. I therefore believe that it is most probably the crank shaft sensor that needs to be replaced. That is my next move once the stores are open again after Memorial Day. So, have someone change that sensor, it's a key input to the "computer" that controls the engine and much else. I replaced the cam shaft sensor myself, $38 for the sensor. Not sure but should be about the same for the crank shaft sensor. Good luck.

    That code (p1391) was discussed here:

    You can replace the cam sensor, crank sensor and every other sensor on the jeep and it will probably still stall. Clean the throttle body, a $7 can of cleaner beats paying $38 for sensors that will (as you mentioned) NOT fix the problem. When the engine stalls unexpectantly (i.e. from not getting enough air/fuel through the throttle body) the sensors involved in the engine turning (i.e. cam/crank) enter an error code. That is what is showing up on your p-whatever code. You can continue to replace sensors until you are blue in the face or you have invested more money than the jeep is worth and chances are it will still not run. Less is more, try the $7 option before you dump another $38 and an equal amount of frustration into it.
  • rashawrashaw Posts: 2
    After replacing cam shaft sensor, which did not fix the stalling issue, I replaced the crankshaft sensor (just above the passenger side CV joint) for $28 and that one did correct the problem. As long as you can get under the vehicle, safely, it's one cap screw that can be pulled with a ratchet and a 12 mm socket, one electrical connector. Haven't gotten to spraying the throttle body yet, does not appear to be an issue based on how it's running.

    my 02 jeep liberty is having a huge problem the mechanic after two days has determined that he CANT FIND THE PROBLEM!! but he does see the problem, the problem with my liberty is...

    after around 20 minutes of driving it wont drive anymore when you press the gas it just wont go!, the power stays on it jerks then shuts down.. when you watch the RPM the do a dance back and fourth.. I can restart it only one time : buy raving the gas then it will only go about another 2 minutes before it wont even click to start.. i know its not the battery b/c all the power stays on but the engine wont start.. i replaced the crank sensor like most have and it still does not fix it... can someone please tell me anything else i should try that will not cost me thousands my liberty has 182,000 so its not worth it to spend thousands to fix the problem if that the case... my boyfriend is all over me about figuring out the problem so i need to so it ASAP>> PLEASE HELP WITH INFO AND IDEAS
  • jkelly2jkelly2 Posts: 1
    I have a 2002 liberty that won't start. It started just once about a month ago, after messing around with the gear shift, I got it going. Last week after filling it up with gas, it wouldn't start at all. We tried over and over. It ended up getting towed. It still wouldn't start at the shop. However, they now cannot determine what is wrong with it because sometimes it will start and sometimes it won't. It is still there, and I am looking for any clues as to what may be wrong with it! PLEASE HELP! Thanks
  • rich14rich14 Posts: 15
    it was the cap position sensor
