I'm stunned at the number of people who don't understand gas mileage, and how it relates to driving style.
First off, THE GAS MILEAGE ON THE STICKER IS NOT A REPRESENTATION OF JEEP, CHRYSLER, OR ANY CAR MANUFACTURER. The sticker mileages come DIRECTLY FROM THE EPA (Environmental Protection Agency).
I have owned my Liberty for over six months, and put over 8000 miles on it. My gas mileage has been consistently between 17 and 21. Usually towards the lower end - but 95% of my driving is city driving - including long traffic jams. I have on occasion seen my gas mileage drop to 15.5. I have driven with many different people and seen a wide variety driving styles. I'm always amazed at the number of people that FLOOR the gas pedal in absolutely normal, in-city driving. On top of that, they JAM the brakes on nine feet before any stop.
See http://www.fueleconomy.gov/feg/driveHabits.shtml for tips on getting better mileage. I would strongly suggest checking your driving style if you're not getting anywhere near EPA numbers with your gas mileage.

I was previously unaware that all you have to do is RESET the average miles per gallon display. Lo and behold my average is reading correctly now. I'm getting between 18 and 22 MPG depending on whether I'm in neighborhood driving or highway. I suggest periodically resetting the average to get a more accurate current reading so that factors in the past aren't influencing the average.

I just bought a 2003 jeep renegade, leather, 4x4, skid plates, step rails.. its got everything except the ABS option... doh!!!.. I bought it used so that is not my fault. anyways I'm going to put my 2 cents in on the gas thing. driving style does count. at 65mph I average 22mpg, at 70mph I average 19.5mpg, at 73mph to 75mph I average 17mpg to 18mpg. I find myself doing the speed limit more often. so next ill try all synthetics everywhere the jeep takes oil, and for the hell of it ill install the tornado fuel saver gizmo that has proved to do nothing by independent companies. Laterz.

I have an 05 Renegade, mileage averages 13-14 mpg. I love this vehicle, but consider this is unacceptable and I will soon be selling it. I was expecting the advertised 17-22. I am one of those folks who also purchased a Camry Hybrid and love the 35 mpg city mileage. I just can't justify a gas guzzler like the Liberty.

My wife just gave up her 2004 Toyota Matrix (31 mpg) for a 2006 Jeep Liberty (13 mpg). She thought she would feel more secure in the winter with a 4x4, but never thought of a mistake of 4 mpg in the window sticker. No wonder there was a $2k rebate, Now $3k.
Is there any recourse?

Press the reset on the readout then check your mpg. If still bad, tell your wife not to have a lead foot. I'm an 18 year old teenager who drives a little faster than most, and I get 25mpg on the highway and 18-20 in the city with a loaded Renegade.

I recently bought a 2004 Jeep Liberty and very happy with the way it rides, but unsatisfied with the gas mileage. I filled up the tank and have only driven 50 miles and I am already on 3/4 tank of gas. This makes me regret buying the car because I will have to spend so much money on gas every month and that was totally unexpected.

I own a 2004 Jeep Liberty Limited and have consistently been averaging just over 22mpg; granted most of my commute is highway miles (I've put almost 95,000 miles on the vehicle), a lot also has to do with your driving style. If you drive at 70mph you will get lower mileage than if you drive 65mph.

The carb air sensor is actually called the air intake sensor. It lets the computer know the outside air temp to help determine air/fuel ratio. If it is bad and thinks it is -40 outside, it would cause the truck to run richer. Would be best to have it scanned by a tech to see an actual temp reading.

Well I purchased a 2004 Jeep Liberty. Do I like the vehicle? Yes. Do I like the gas mileage?..."cue dramatic music"...NO!...My God the thing is an absolute pig on gas. I'm sure an Arabian chorus line belts out party tunes every time one of these things are sold. I love the look and feel of the vehicle. But I'm afraid I'm going to have to kiss it goodbye. Anyway, that's my 2 cents... or actually 80 cents if you factor in the rising fuel costs...

I've had a 2002 Jeep Liberty Sport for 7 years (purchased May 2001), and love this vehicle. It drives great, only one problem in 7 years. The a/c compressor gave out last year and had it replaced. I just put some nice new wheels and tires, with a new alignment. With 96k miles, the Jeep drives almost like new. People don't believe the car is 7 years old. Regular oil changes and a tune up have gone a long way!
The biggest complaint it gas mileage, I get between 15-18mpgs, the tank gets around 260 miles per tank.
Would I buy it again, YES! This has been the most reliable vehicle I have ever owned.

Own a Liberty in Mexico on the coast, bought it new in 03 and driven 72,000 miles. The car and warranty along with it's reliability are excellent and it has stayed corrosion free despite being parked in the open 75 yards from the Ocean no mean feat!! Alas the gas consumption at 15L / 100km is appalling. The engine has great torque but is coarse and hates reving. The gas consumption is worse than my Chevrolet Avalanche 5.3LV V8 Vortec for the same driving. With the platicy interiors of the new Liberty let alone the Patriot and Compass, this will be my last Jeep. I will enjoy this one and it's funky look until it expires.

My fourth Jeep is a 2004 Liberty - I thought the 3.7L engine would get better mileage than the long time reliable 4 Liter it replaced. Saying it is a gas hog is being kind - even when driven conservatively. The Grand Cherokee V8 will actually get better mileage. Sorry but Jeep missed the boat on this engine design.

I'm a Canadian that bought a new 2004 Liberty in Georgia while I was working there, and kept it when I returned to Canada in 2005. I, too, was unhappy with my average mpg with the Jeep.
Last week, I filled my tank and reset the trip odometer to zero. I tried not to change my normal driving habits (mixture of city and highway driving). By the time the fuel warning light came on, I had traveled 290 miles. So I went and refilled the Jeep. It took 54.8 litres, or 14.5 US gallons. So, dividing 290 miles by 14.5 gals, I got 20mpg for my last tank of gas.
I was a little surprised that the Jeep took so little fuel to fill it. The vehicle spec says that the fuel tank capacity is 19.5 gallons. If I take 290 miles and divide it by 19.5, now I only get 14.9 mpg. How can there be such a discrepancy in how much gas I can put into my vehicle versus what is stated on the vehicle spec sheet?
So, I'm running the "test" over again this week. I'll see how many miles I can drive until the fuel light comes on again, then fill up my Jeep to see how many litres (gallons) it takes. If I get anything different, I will post an update.
