#142 of 207 02 Liberty Warning Light/Speedometer Issue by npearl88

Jun 22, 2011 (1:55 pm)

Hi,
  We have a 2002 Jeep Liberty Limited Edition 4WD (3.7L V6). It has about 125k on it. Recently, the Check Engine, ABS, Brake, and Part Time light have all come on. Brought it to our mechanic and he replaced some sensors with no success. Also, the Speedometer no longer works, just stays on 0mph all the time.
About 5 minutes into the drive, the power locks will re-lock, and the speedometer will shoot up to 70 then back down, then shoot to 30, and back down, then stops working. I feel as if it has to be some sort of electrical issue, but our mechanic "doesn't have the proper tools" for such a task. Any ideas on what could be the issue? Any help is appreciated.

I've not taken my 05 Liberty CRD to the dealer for the vibration. I took it to a local mechanic - no improvement. The issue remains, when travelling for the first 1/2 mile in the morning, there is a stop sign. While approaching the stop sign it appears the transmission is still in one of the higher gears; because as I come to a stop the transmission will vibrate and the engine will shut off. It appears the transmission is still in third or fourth gears where it should be down shifting to first gear - thus resulting in the engine shutting down.

Take this for whatever it's worth but I have a 2008 4X4 Liberty and I was reading the manual pertaining to the fuel, The manuel is probably the same one you have but as far as the gas recommended is 87 octane. according to the manufacturer the computer was specifically designed for that grade of fuel. according to them if you use higher octane or additives the engine may not run as well but using a quality gasoline will and will need to be serviced more often. The same applies with any gasoline with a mixture with methanol blend.
I aquired my Liberty 3 year ago from someone who bought it but couldn't afford it, I wasn't looking for a Liberty but I like it a lot. The reason I was reading about the fuel was because at a idle I noticed a very slight tapping noise and I found out that it is normal so long as when you excellerate it goes away. I seem to be the only one that can hear it maybe it's just because it's my vehicle. It's a second car for me and I don't drive it much, it spends most of it's life in the garage. It has 6,700 mles on it. well I hope this info helped you a bit and I do realize I could be wrong but I'm only letting you know what I read. It was on page 273 if you're interested. Brian, San Diego

My 03 only has 32k miles and there has been no tapping issues. All gas in the area has ethanol. My manual recommends premium when towing a trailer or driving in high elevations.

My book says an octane rating of at least 87. My engine would rattle and misfire light would come on regularly. It also used a court of oil every 1000-2000 miles which signified ring wear.. I have gotten rid of it.

Hi,
I bought my Liberty 2011 in mid April of this year. Same problem from day one. I happened to have a steep driveway into my garage. I really have to stop and then back into my garage really slow. So at that point Jeep starts to shudder and jerk as I am backing up.
 
Also, same problem with the speeds around 55 miles per hour. Has a feel as though it is "hanging up" or I call it" feels it dives in the hole" before accelerating. I thought that it was a break in time just like most of you, but then took it in the dealership. After having it in there for a week, they swapped a torque converter, which I mentioned to begin with.
 
Well, it didn't go away. I am going to call them tomorrow and see what can be done. I will try to drive another vehicle and see if it does same thing.
 
We'll see what happens. Was so excited to own a Jeep and there you have it.
 
Dang it! Let me know Ya'll if anyone discovers what the problem might be.
 
Many thanks.
Serge.

Bought a new 2011 jeep liberty and it has the problem just as you have described. Sometimes I can even hear and feel in shift hard into a certain gear. The transmission seems to shudder and there is considerable jerkyness when driving the vehicle within the transmission. I took it the dealer, they had it for a day and said that they could not find anything wrong with it. I would think any mechanic worth their training would be able to just feel how it drives and know that something was wrong. Now I don't know what to do. I am glad some others are having the same issues and I'm not just imagining this issue. Anyone know of a solution?

Do you have any warning lights coming on? Our jeep had a misfire in the engine. It turned out to be poor fuel quality. Check your transmission fluid level. If it shutters and jerks, It could be the fluid is low. Also take it to an Advance or Autozone auto parts when it is acting up. DO NOT TURN the vehicle off. Ask them to check your computer for codes. Good luck.

I am having the same issue. I have driven a wrangler for 16 yrs and I am used to the way it drives. I purchased a new 2011 Jeep Liberty Sport in July this year and was surprised to find that when I take my foot off the gas and "coast" at a constant rpm (mostly at 1500), that the engine feels like it's hesitating when switching gears and I also feel a jerking when it kicks into gear and when I accelerate quickly from a complete stop. I took it to an authorized Jeep dealer a few weeks ago and test drove it w/the tech and of course couldnt really get the car to repeat the behavior. The tech allowed me to test drive a different brand new liberty from the lot which did the same thing but worse. HERE'S WHAT IT IS.......OR AT LEAST WHAT THE TECH TOLD ME......these new cars have an "ECO" mode which is a lighted setting on the dashboard - you will notice when you take your foot off the gas, the light says "eco on" which means the engine is switching into a more fuel? efficient mode. The tech explained what the engine is actually doing, something along the lines of using less cylinders which are not equally balanced?? Basically there were no codes so they told me this is just how the car is and there's nothing they can fix. I'm curious as to whether this is actually something we all just have to deal with or if there is a solution..............

Serge & others,
 
I have an 05 Jeep Liberty CRD. Approximetly six months ago I notice an issue with the drive train only when the engine/transmission is cold. We live a 1/2 mile from the first stop sign. As we approach the stop sign it "feels" like the transmission is in one of the higher gears - as a result there is a vibration comming from the drive train and the engine stalls. I suspect if the transmission down shifted as it is designed to do, the engine would not stall. I've call a dealer and he states there is no recall on the transmission. After that initial stalling at the first stop sign, there are no more issues as I approach any other stop sign. The transmission down shifts to the lower gears and the engine continues to run.
 
I don't know the fix.
 
Thanks,
Edgar
