2008 Jeep Liberty-Dead battery issues w/ a new battery

My 2008 has approx 26,000 miles and is on battery #3. The most recent is a month old and it continues to go dead. Usually it is so drained there is NO power, not even to open the doors (they have to be opened using the key in the door). Once it is jump started, it will run fine for a day or even a few weeks and then do it again. The dearship has changed the battery twice and replaced the radio/nav system. I wonder if it has something to do with the auto start feature. This started 2 months after I bought the car brand new.

I found once I removed the fuse for my radio/navigatin system, I had no problem with my battery being drained again. Apparently there is a problem with Chrysler radio's still using power even after the car is shut off.

Unit has a draw somewhere that needs to be addressed. I have found the auto starts sometimes can cause this. But if the draw is through the negative side it could be tough. You should take it to the dealer and have them perform a draw test on the entire vehicle.

2008 Jeep Liberty error code gate on dash and interior light will not turn off got new battery and still doing it

can i buy a comma? says vanna white?? LOL !
ok, the battery drains, so you got a DRAIN, called phantom drain.
or dark current.!!
we use a thing called an AMMETER (DMM) to find all drains, easy

do you have one, want to learn or just wanting wild guessing.

on any 08 liberty, we check the scan tool data.
oops it shows battery low, wow even the PCM sees that.

new batteries do not fix drain.
nor dead alternators.

get it serviced, by a pro. ?

1: charge battery (rested its 12.6vdc )
2: start engine, scan tool shows, what DTC errors (post em')
3: battery voltage is , 13.3, to 15vdc running, if not charge system is faulting.
4: ok all that is ok, i then key off and measure bettery cable neg lug drain current, if 0.010a to 0.040a its ok, if over 0.1 amps its a drain.
we then find the drain cause, ASK? its not hard with a meter.
but i bet all you wanted is a wild guess.

Jeep liberty battery drain

look online but i have found a few were the clock was the issue. Pull the fuse to check his. if not the clock, look at all the grounds should be 3, or pull off neg cable use a test light clip to battery touch the cable & if it light there is a draw. You can pull each fuse 1 at a time to also help find the issue.

Possible solution - This happened to me and my battery was dead in my key fob and also I needed an ignition switch because a piece on it was broken which therefore wouldn't turn to start the engine.

2008 jeep liberty mileage error

You need to take it in to the dealer and have the code that is stored when it says error read with a scan tool. No the cluster will not need to be replaced, repaired maybe, but wait until the testing is done.

Jeep liberty 2008 radio went dead changed fuse but still does not work

A lot of vehicles have two fuses for the radio, one for the battery side and one for the ignition side, I would get a test light and check all the fuses because it may be shared with another circuit and not be listed

Dead battery

I have a recall notice for your Jeep. It states that the radio is not powering down correctly and that the radio should be replaced by the dealership.

Email me at because it is too big to post here.

Engine dies, starts rough

Most large parts stores read codes free. Most common cause is crank sensor, but I'd have code checked before buying anything.

Jeep liberty gas mileage

to increase gas mileage make sure you keep on top of tire air pressure you can also have your tires filled with nitrogen instead of air also a K&N air filter does wonders and is good for lifetime worth every penny. another smart move is to use a fuel system cleaner regularly Lucas makes great products for this try local parts store.
