anyone else having problems with poor gas mileage?

one of the reasons why I bought a Jeep Cherokee was a good gas mileage but it seems that my first tank of gas was 15.7 miles per gallon The dealership says that I had a heavy foot since I used to own a Mini Cooper and you have to wait until 300 miles for the computer to calculate your driving style. Now I am driving using the fuel economy screen and I'm driving sometimes under the speed limit and I'm only getting 21.8 miles per gallon and I'm on my second take a gas that I am using midgrade fuel thinking that it might help on gas mileage

I am driving a four cylinder 4x4 limited Cherokee with the cover package and sunroof I don't know if it could be the extra weight what could be giving me the poor gas mileage

I'm very surprised to hear that. I have the V6 and I'm getting averaging around 20. Maybe you just need to break in the motor a little more

The mpg leader will always be the fwd I4 latitude or sport. There have been posts here with those KL's running 28+ mpg. I'm fairly happy with my decked out Trailhawk's 21-22 mixed mpg.

Stop using mid grade. The 2.4 is designed to run on regular 87 octane. You will see no benefit to running higher octane (other than draining your wallet faster)

Check your tire pressures. If they are low it will rob mpgs.

Are you in a cold climate? If so, winter blend gas is being used and could account for reduced mpgs. Also are you idling the engine for long periods?

What type of driving have you been doing? Stop and go? Highway? Both affect mpgs.

I'd advise anyone who doesn't feather the gas pedal like an 85 year old driving to church on sunday to buy the V6 version.

I drove both versions before I bought my V6 TH, and the V6, on the same course with the same driving habits, performed better than the 4 in both handling and fuel economy.

21 mpg doesn't sound bad. What were you expecting to get out of your Cherokee? If it kept at the 15 mpg you were getting at first, then I would be worried.

Just finished a ~1,500 mile Thanksgiving vacation road trip. Went from Cincy to Tuscaloosa and back then Cincy to Marietta, OH and back. Computer calculated 21 average mpg. I have a V6 Trailhawk with tow package using 89 octane. Most of it was highway, of course, and on overinflated tires before I read the tire pressure thread on here (thanks guys!). I swear the Jeep was getting 21-22 mpg on the highway during the first half of each tank then would jump up to an average of 24-25 before needing to refill. Probably just the topography of the trip and not some weird mileage efficiencies found on the back half of the gas tank.

Unhappy fuel economy

I am having the same problem... Does anyone else notice it not shifting into 9th gear? Sure, if you move the stick over and manually put it in 9th it SAYS 9, but doesn't change. Flip it back over to D, then back to M, and it will be on 8 or 7 again. Irritating. I love my Cherokee but it is not getting anything close to the 26+ highway promised.

Unhappy

I am having the same problem with my V4 4X4 Cherokee. I have driven over 3500 miles and the best I can get on gas mileage is around 19 to 20 mpg. At first I was only getting 14 to 16 miles per gallon. I had the dealer take a look and they did a software upgrade, which only improved the mileage a little. I wanted the V4 for better mpg and was expecting around 25 to 27 mpg based on combined local and highway driving.
