My hate & Love of Jeep Liberty 2004 |Top 6 common problems for Liberty 42RLE

Posted by HJL_ADMIN 1 on

Before Fiat took over the company, Jeep used to have great reputation for its engine stability and power performance.

Before Fiat, Jeep was owned by Chrysler after 1999 and in which, the Jeep Liberty 2004 is the 1st generation of this series which still have solid strong engine from Chrysler breeds.

Jeep Liberty is well known as the pioneer of off-road SUV vehicles.

Yes, that kind of muddy, exciting, rocky off-road as you picture.

So for the 1st generation liberty 2004-2007, the overall performance is contrarily stable than other years models because it still came from the Jeep pedigree originally.
In today’s video, we’re going thru common problems of Jeep liberty 1st generation and
jeep liberty years to avoid.

Yes, let’s see the why people love & hate about this legend car.


Top 6 Problems of Jeep Liberty 1st Generation & 42RLE

We talked about lots about Jeep liberty used transmission 42RLE in our last video. 

This 42RLE is the transmission for Jeep 2005, Jeep 2007 and also other well-known car models like wrangler and 300S.

There are some common problems with this off-road iconic model and here let’s talk about them.


#1 EGR Removal

This EGR, the exhaust gas recirculation, plays an important role to recirculate the exhaust gas back into the engine combustion chamber.

The diesel engine tends to emit heavier Nitrogen Oxide, so called the NOx, which is harmful to humans.

So with the function of EGR, we can control and decrease NOx emissions in engines.

If the EGR are stuck or polluted like the photo shows, it will affect its function and let air-fuel-mixture get back to combustion chamber.

Our suggestion is to clean the electronic EGR Valve and use carburetor cleaner to clean the hose and valve periodically.


#2 Transmission Trany Problem

Once again, we’d like to mention the transmission problem which in jeep case, is commonly known as the gear not shift out of 2nd.
For Jeep case, this is especially happened because of the 4WD mode button got stuck.

So, here we got a handy hack to quick repair this situation especially when you see this light on your dashboard or when you feel the gears work not smoothly.

1st, switch the gear and stop it at the Neutral. 

2nd, push the 4wd driver mode and make sure it stop at the exact 4wd mode.

3rd, shut it off the engine.

4th, re start the engine.

5th, push the gear back to Park and push back the 4WD mode with the engine is on.

6th, shut the engine off again and re-start it.
The light shall go off now.

This is an easy method for you to repair the situation when 4wd mode button got stuck and influence the gear function.

42RLE transmission has some common problems which you can see in our last video. 


#3 The Valve Block

Simply replace the transmission valve body for 42RLE may sometimes save you fortune.

Very often the transmission problems come from the valve block failure. 

If you can sort it out at the early stage, for this solenoid block pack it may cost only $100 for the rebuilt one.

And it can save you hundred thousand bucks to overhaul the whole transmission.


#4 The lock of Power Door

The electronic components age over time.

The reason to cause this electronic power door lock problem is the actuator which controls the door lock function.

This can be happening in any of Jeep Liberty used doors.

Also the binding or latches may be problem causes.

If you heard any squeaking or grinding noise when you try to lock or unlock the door, this is the sign that something goes wrong with the door locks.


#5 Motor of Power Window

I know this is a very obvious problem to sense when we use the window switch but it fails to function properly.

Very typical situation is the motor burnt out with the power sent down there but the regulator couldn’t move because of some reasons.

Ex, the window glass gets frozen and stuck in the up position in the snowy day when you start the engine in the early morning.

In this situation, the motor tries his hard as possible but the windows still doesn’t move and then the motor burnt out.

If so, the solution will be replacing the regulator motor or even whole assembly.


#6 Internal Engine Valve

There will be the engine light coming on or flashing on the dashboard when the engine valve goes wrong.

Sometimes you may also feel the engine power is loosing.

These intake valves require replacement when you sense the above symptoms


So these are the common problems for the 1st generation Jeep Liberty.

When you’re considering of the Jeep Liberty used cars, remember to put these problems into your must check list.

Next, let’s see the charming features of Liberty.

#1 Parts cost and availability
There are lots of common parts for both Liberty 3.0 and 2.0 gasoline version.

The parts are not expensive and the availability is plenty.

From exterior fender hood mirror to the engine mechanism parts inside the engine even the transmission, you get what you need.

This makes the maintenance and repairing super affordable and cool.


#2 Diesel Longevity  

Truth is the Diesel runs much longer than gasoline.

This is definitely good for miles per gallon when you consider of any car purchase.

Especially for the diesel fans, this is a feature beats many other cars.

Meanwhile, you’ll be surprised this 4-cylider 2.8 diesel engine has the excellent economic performance which is around 30 miles per gallon. 


#3 Super Jeep Community
Hey you have to admit that the car owners of Jeep are super friendly and helpful.

Many useful information and knowledgeable /people are in the community and ready to support each other anytime.

No matter what problems you get, you can just go on facebook to look for suggestions and solutions.

Definitely a great bonus!

No more worries for the maintenance service and car repairing.


#4 The cargo space & 12V power charging in back

There is an adapter just right in the trunk to make the charging super easy especially when you do the off-road trip. No matter you go camping or hiking, this adapter is truly cool for power charging.

And speaking of the storage space, it has nearly 69 cubic feet with seats down and 29 cubit feet when seats are up; which is awesome and practical to fit to our outdoor journey demands.

#5 4X4 Wheel Drive Capability

Apart from her off road ability, this 4X4 wheel drive also enables our Liberty can run great even in the nasty snowy weather.

The most reliable and capable vehicle you can trust under such awful weather.


#6 Towing Capability

You will be surprised that how big the towing power this 4 cylinders SUV has.

This high towing capacity makes it more easy to move when it comes to off road trip.

Couple years ago when I visited Brisbane, I saw many families have their vehicles towing the boat to the seashore when Friday coming.
So pity the Jeep didn’t export their Liberty to Southern Hemisphere; I’m sure the Aussie people will love its towing capability for sure.



Overall speaking, I’ll still put Jeep in my 1st choice when consider of an off-road vehicle as its features still make itself outstanding from the others.

Just pay more attention on the symptoms and problems we mentioned earlier and our jeep can accompany us all the way.
