Replace air filter .change spark plugs and wires.transmission slipping .check tranny fluid.if you got manual transmission.clutch could be slipping.low tire pressure.brake could be dragging.high speed driving and a lot short runs.stopping and going burn a lot of gas.scan it to check oxygen will cause fuel consumption.

2010 5.7 liter. Does the dealer have to adjust anything to improve gas mileage?

to get an an out of paramaters setting for the air fuel mixture in the ECM I would consider a change in altitude of around 3000 feet would be necessary before the ECM would need re- programming
I would suggest that you run the fault codes as the MAP/BARO sensors may be faulty
also if the driving conditions have change ( flat to hilly) will account for lower fuel economy

Buick regal 92 3.8L Horrible fuel mileage

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.

Just moved from New Mexico to Florida and the gas mileage in my 2000 Grand Prix and dropped to about 10 to 12 mpg. Is it the change in elevation?

I just dealt with a similar issue.I moved from Florida to Missouri and yes there is a difference from elevation and the humidity in the air and gas mileage.

Gas mileage has tanked on 2000 Grand Cherokee Laredo w/V8

I'm not sure I have a solution to this but the change in altitude should cause a change in mpg. However, the car was not put in a box and shipped there, it was driven...and should have adjusted gradually to the change. (computer should re-calibrate). The only item that may be affected would be the map sensor. Possibly, since it has always worked at one altitude, it may have worn in that area and is hanging up and unable to adjust.
If the trip was made quickly, the computer may not have re-calibrated itself yet (depending upon how long it's been in Alaska) You may want to try disconnecting the battery and then re-connecting it, or it may need to be manually re-calibrated using a scan tool. The computer likely is working properly though otherwise with that kind of mpg you should be blowing a bit of black smoke out the back. Only other thing I can think of is to check the air filter to make sure it's clean and not restricted.
as far as the brake thing goes, after that, I would shy away from the dealer unless it's for free warranty work...I could replace the entire system three times for that price (gold plated parts?)
Well, like I said, not a solution, but my thinking on paper!!
Good luck!!!

Poor acceleration, poor gas mileage

I have the same problem as talked about above. 2002 Hyundai accent gsi. HORRIBLE gas mileage. I only get about 320 km per full tank. My driving habits are good. i took it to the garage and they put it on the computer and no error codes showed up. Question: Can a MAP sensor be faulty but NOT show up on the computer diagnostic? I had my O2 sensor checked out and my exhaust, and changed the flex pipe. Car runs pretty good just horrible gas mileage and kinda crappy power. Changed fuel and air filter. Cleaned the fuel system entirely ($80 at garage not $4 bottle).

Anyone ever use a resistor in the MAP sensor?
