I feel cheated
 

i bought a 01 grand cherokee, took it for a nice long test drive and promised me 22-24 mpg on the highway, as high as 26-27 at 55, and decent even in the city.

picked it up and I'm averaging aboy 30%less all from before, 12.5 according to the gauge. the brakes were sticking, fixing that picked it up a little, but still crap. They installed 4 new balljoints, i think maybe the alignment is way off, must have gotten an alignment with bad parts. I upped the tires to 38 psi, 5 above stock, that fixed it a little, but still not as good as the tet drive

even takes more gas pedal to make it go, something is deinately up. My scangauge 2 is on the way, i hope that will shine a light on the subject.

It's a GRAND CHEROKEE, come on! You seriously can't be shocked by this.

if this is what the computer told me i would have walked away, the readings are worse and takes more throttle to maintain speed

something is up

First, onboard computers are not good for getting an accurate MPG rating. Go by what you actually fill the tank with and how many miles you drove. The scangauge will also give a better reading than the onboard computer. Also, I don't know how long you've had it, but you should be comparing your MPG tank to tank, not day to day, because there are a lot of factors that can affect it.

Here's the EPA's website, click on 2001 Jeeps- Search by Manufacturer

Depending on your model, you're looking at 13-14 city, 19-20 highway. Maybe you were going downhill with the wind or something for the 26-27MPG that you saw.

If you bought a Jeep Grand Cherokee expecting good gas mileage, then you made a foolish purchase.

Here is your EPA MPG :

I've driven both the classic jeep straight 6 version, and the V8 4.7 chrysler.

They both get about the same mileage. Right about the 20 range on the highway and that's if you're being a very good boy. Most of the time my friends reported mileage in the single digits while in the city. The on board mpg gauge is full of crap, as well. It would over report by 3 or 4 at a time.

Could you explain this sentence:
"i bought a 01 grand cherokee, took it for a nice long test drive and promised me 22-24 mpg on the highway, as high as 26-27 at 55, and decent even in the city.

Who?
Who promised you?
you have over 50 posts. so you have read over 200 posted comments from various threads.

WTF are you complaining about!!!!!
Where is the surprise?

How, in anybody's right mind, can you possible make the statement that you were cheated?

If I sound a little rude, good, that's the message.
You buy a car that was designed and built 10yrs ago. DO you realize that in the world of effecient mpg that was the stone age?
And like Frank Lee said......"it's the GRAND Cherokee" THe Heavest most loaded one they make.

the display showed as 23- 24mpg instant on the highway on the test drive. thats what IT, the car itself promised. Now that I picked it up it's barely shows 20 instant on the highway. For whatever reason it was indicating much better MPG on the test drive then after I got it. THAT IS WHY I FEEL CHEATED, THE BEFORE AND AFTER TEST DRIVE NUMBERS DO NOT MATCH, no matter how I drive i cannot get more than 20. I have no idea what it actually is as I have not filled up for the forst time yet, but if you take a prius for a test drive and it shows 70mpg with your driving style and you buy it, then cannnot get more than 55 mpg after yiu take it home, would you not feel cheated? same thing.
I know a jeep is a pig, had the display said 20 on the test drive all would have been well. It's like a woman being the perfect little lady, you marry her and turns into a *****. Thats what this jeep did. promised better mog one day then it could deliver in the days since.

How many of you guys get more than the EPA estimate? could you with a jeep? I'm sure you could, and why could I before and not now.

Instantaneous MPG is different than average.

ok, you need serious counseling. IT didn't PROMISE SHXX. IT is an inanimate object.
The word 'promise' implies a covanet or agreement. IT can not do that.

Maybe you would seem more reasonable if you said "displayed"........
