I got a new-to-me Jeep Liberty 2005 in February. The check engine light came on after a few weeks. Our mechanic replaced the catalytic converter twice. After the second replacement it went out after we drove for a while, but after the second one it never went out. We are now using high-test gas (to prevent carbon buildup?), but that hasn't worked either. I need to pass the emission test soon.
View 6 RepliesI have a 2005 jeep liberty 3.7L with 60,000 miles on it. The engine light when on 2 weeks ago and gave a p300 code. the dealership replaced coil and plugs, I believe. Then would start rough when cold, the engine light would blink for about 10 seconds then remain on. the car runs just fine except when cold....first minute of starting it. they checked for head gasket problem, and cant seem to find the problem. They told me that this could just be something that happens. I don't believe that. I have no loss of power, no hesitation. Runs fine 99% of the time
View 19 RepliesI have a 2006 Jeep Liberty 2.8 Diesel. It has about 57000 miles on it and when I took it to be inspected, a Code PO 299 came up. The dealer has done quite a bit of work to it and cannot find a way to get this light to stay off. When something is done, it goes off until it is driven, then it comes on again. So far the jeep runs great, but it's hard to pass inspection unless the light goes out.
View 7 RepliesI have a 2005 Jeep Liberty with about 129K. The car overheated and resulted in changing the head gasket and piston rings. Now the car will not start with all six spark plugs installed. It will only start and run for a short period time with three spark plugs on the driver side installed.
View 19 RepliesOver the past month or so I've noticed that my 2005 Jeep Liberty Limited has started to make a creaking noise when it's a little off balance, such as driving down and uneven drive-way. I believe it's coming from the back?
View 4 RepliesI have a 2005 Jeep Liberty. It recently started making a noise that I think is most accurately described as a groan/squeal. It only happens at low speed, < 20MPH, and happens more often the lower the speed. It also seems more likely to happen when the vehicle is turning. I haven't noticed any other problems with the car. The brakes and serpentine belt were recently replaced.
The brakes were replaced because they were starting to get old, looked corroded, and were starting to squeal when braking. The serpentine belt was replaced because it had a crack in it and was under warranty after being replaced for the same reason only 10 months ago. I don't believe that the noise is related to the brakes as the noise has occurred many times when the brakes were not being applied and it does not appear to occur any more or less frequently when they are applied
So recently i knowingly purchased a car with a blown head gasket. Got it fixed at the mechanics and also changed the timing belt / serviced the car. The car also had intermittent check engine light however the mechanic said it was just the O2 sensor or something and it wasn't worth fixing ($300 to replace it).
Now the car (automatic subaru liberty) drove fine for the last two weeks but my brother took it out to go to the snow and on the return trip the car starting to emit loud clunking sounds from the engine, the brake system warning light also came on and power was reduced and my brother pulled over, and checked it out. The car starts, but its only limited to around 15km even when flooring the car. The car free revs in neutral but emits a cracking sound.
Do you think the transmission shit itself? On cold mornings the car would take about 1-2 seconds to change engage drive / reverse.
Okay, so I've been hearing this strange sloshing noise in my Jeep Liberty 2005. It happens when I start off from a stop and usually around 15mph. It seems to be coming from the front of the vehicle (engine). And I'm not the only one that has heard it so I'm not crazy.
View 3 Replieswe have a 2005 Jeep Liberty. It has about 150000 miles and every few days it makes a sound like a guitar string breaking. sometimes, while we are driving, other times as we wait on a red light and sometimes after the car is turned off. What could be causing this?
View 7 Replies2003 Jeep Liberty Sport, 156 K miles, Check engine light has been on for months now. First occurrence was when driving, and car started to knock as though I was shooting 50 cal machine guns. Stopped vehicle, shut off, and upon restart, engine ran smooth. Now, almost every time after engine has been running a while, and I am going on a down slope, the check engine light starts to blink, and engine starts to miss. Took to my mechanic, and so far, I have been told and have replaced, Fuel pump, Spark plugs, coils, and wires, cam sensor. Latest and most recent with promise that this has to be it, I replaced engine computer.
View 16 RepliesMy engine seems to misfire when I first start out and then runs smoothly. The first mechanic got a random misfire from the diagnostic and replaced all the cylinder coils which worked for about a week. The second mechanic ran a diagnostic which said random misfire and he said it was a loose spark plug. This worked for 4 days then it started misfiring again. There's no violent shaking or backfiring. I don't know much about cars but it seems odd that it doesn't keep misfiring. It's a 2006 jeep Liberty with 87,000 miles...
View 9 RepliesMy '03 Jeep Liberty developed a quite audible hole in the exhaust system overnight (sound is coming from engine compartment) and at the same time has begun missing. The missing occurs most often in the low end of gears - once through the gears (in 4th or 5th) and at highway speeds it smooths out again. My question is are these two problems related?
View 1 RepliesI was driving home from a backpacking trip when I noticed a knocking coming from my engine. It got worse as I drove up a large hill and suddenly became very loud, and I lost the ability to accelerate, power steering and brakes.
I managed to pull off the road and checked all my fluids, everything was good. No smoke from the engine and it was not over heating. I was unable to start the car, it wouldn't even make a noise, just dead.
Check engine light is broken and remains on. No other warning lights came on while I was driving.
I own a 2010 Jeep Liberty and this is my first RWD vehicle (when set in the normal 2WD mode of course). I notice that whenever I accelerate from a stop, on even a slightly wet road, the rear wheels spin and I get the traction light on my dashboard. I then need to take my foot of the gas and accelerate ohhhh soooo slowly. I've never had this kind of wheel spin on my previous AWD or FWD vehicles. Is this a known "feature" or RWD vehicles? Or maybe my one year old tires are inadequate? With my Liberty I could try switching to 4WD LOCK mode before attempting the acceleration to see if this works.
View 19 RepliesI own a 2001 Jeep Cherokee with 104,000+ miles. It runs great and doesn't have any issues. However, i started it up this morning and the check engine light came on. Should this be concerning? I haven't done any real maintenance on it since it runs so well. And i guess that's my other question - what should i do to the Jeep to keep it running for another 100,000+ miles? Spark plugs? Timing belt??

View 2 Replies1999 Jeep Grand Cherokee 4.0. Check engine light will not go out. Took to Autozone , Orileys ,and Jeep Dealer. No codes found. Replaced cooling fan relay, when light first came on. Everything works fine now. Have tried myself to shut light off, disconnect batt. cables 10 min, 30 min. and other methods, no luck , still, on ? I have even traced the cooling fan relay wire to PCM, all OK.
View 3 RepliesSo this little gem of an SUV has been good enough to me over the year that I have had it, but it is one of those used vehicles that has me scared to look underneath cause there is always something a miss.
I have been having some power problems and the OBD check engine light has been coming on. The engine like to putter like if it's not getting enough fuel from a clogged fuel filter when it gets going, hot or cold. Have confirmed that the fuel pump is with proper voltage and pressure. Though haven't noticed a big difference with the new filter. The check engine light cycles a code of 21, which is refinanced to the O2 sensor, both upstream and down stream. That tells me that there are TWO O2 sensors for this model. And research has confirmed this. One ahead of the cat and one behind the cat.
Here's the kicker, I only have one O2 sensor at the head of the cat and the location of where the second one would be located is only a solid section of pipe from cat to muffler. I haven't been able to track down the plug connection for the second sensor and these codes and problem only came after I gave the Jeep a tune up.
1994 Jeep Grand Cherokee Limited V8
I have a 2000, Jeep Cherokee 4.0L. The check engine light, keeps coming on, and the scan tool, shows P0300, P0301, P0302, P0303. Misfires in #1, 2 & 3 cylinder.
I replaced the Coil Pack & all spark plugs with genuine jeep parts from the dealer. What might be wrong or other things to check?
I have a 1999 Jeep Cherokee Sport with 140K + and recently had an oil change. I went on a 8 hr road trip split up between 2 days (there and back). On the way home I noticed my oil pressure gauge acting funny, going up and down but not past 40. Today, I drove home from work (10 miles or so) and the check engine light came on and the oil pressure gauge was very low, almost 0. I made it home but was very nervous and noticed both today and this weekend there was smell, burning or burned type smell. What should I do? I don't really trust the garage that changed the oil and was skeptical taking it there but was in a pinch.
View 12 RepliesI am having a “Check Engine” light problem on a stock 06, 4 cylinder Jeep Wrangler with manual transmission. A local highly regarded independent mechanic has had it in his shop 3 or 4 times for more than a day each time. On the first visit he replaced a purge solenoid valve and reset the light. It stayed off for more than 400 miles and then relit. He went over it and checked the wires and connections and reset the light. Again it stayed off for some time and then relit. He has checked the Jeep site.
After the last visit he suggested I drive it and see if it would reset itself as it had been doing in the past. It did reset itself twice but it only stayed off for 10 miles the first time and 2 the second. The code indicates an electrical problem and he is now planning to drop the fuel tank and check the wires and sensors there. The next step may be an ECM transplant. This is only an emission system problem and the mechanic says it is OK to drive. We do not have emission inspections here. How important is it to fix the problem?
