Jeep Grand Cherokee



  • I am debating on buying a '98 Grand Cherokee Limited with it being 4wd all the time. What experience does anyone have with the gas mileage that they do? Any other problems that I should know about? Thanks for any information that anyone can give!

    It sounds to me like you are definitely overheating.
    I have replaced both the water pump and the radiator on my '98 so it is most likely one of those two components.

    What mileage are 05 owners seeing on the highway with the 4.7l or the Hemi? Is there much difference between the two engines cruising at 85mph or so? I know city mileage will be terrible and favor the 4.7, but I'm more concerned with range between fillups on the interstate.

    Diverging for a moment here, I don't understand why manufacturers build SUVs with such small tanks. 300+ hp gas sucking V8, barely any more gas than a Camry, I just don't get it.

    It is kinda like an oxymoron...if they put in 30 or 35 gallon tanks, you will certainly gain in "miles per tankful"...but the weight of 35 gallons of gas when the tank is full would probably drop the city mpg by 2-3 mpg by adding much weight...then, the EPA city mileage would be so poor that few might buy the gas hogs...tradeoff, I think...

    Pickup trucks, OTOH, are designed for folks other than soccer Moms, and so they can come equipped with 35 gallong tanks, or a second fuel tank, because they are designed for working...IMHO, and YMMV...

    This time around my other half is making the vehicle choice. Now that Chrysler has matched the employees pricing and additional discounts, it might be possible for us to buy another car. I'm thinking that the Hemi might make more sense - we do mostly highway driving and I wonder if we would have the extra power without sacrificing too much gas mileage (he's also thinking about a full sized pick-up). Am I just dreaming? We both drove it and liked it (I especially liked it better than the Chevy pick-up, who's seats are way too big for me). Is there anything I should be bringing up to him one way or the other about it?

    I don't think its the weight. An extra 10 gallons of gas only weighs about 63 pounds. Jeep didn't blink at adding 500 pounds in this redesign, and neither have most other manufacturers.

    I'd like a fullsize truck with a 600 mile tank some of the time, but I have to drive and park in the city too. Always a compromise.

    Do I stand corrected???
  • paulepaule Posts: 382
    Well, I'll throw my two cents in being an engineer.
    My guess is that it is a space constraint issue. 20 gallons is a pretty decent size giving adequate range but is still a pretty large tank to package in a midsize SUV.
    Pickup trucks tend to have longer wheelbases allowing larger tanks.

    I'm thinking about trading my 2001 Chevrolet Tahoe (5.3L V8) for a 2004 JGC with the 4.7L V8. Any known problems/issues with this Jeep? What is the average gas mileage you guys get? How is the ride?
  • marsha7marsha7 Posts: 3,703
    I do not own either, but from what I have read on numerous posts, and which will be confirmed by those who own, you may be downsizing your vehicle in size, but your mpg will be equal to, or worse than, your Tahoe...for some reason, even those who love their Jeeps seem to comment on the poor mileage they get on their vehicles, whether 4.7 or 5.7 engines...give it about 10 posts, and you will probably have your answer... :shades: :shades:

    in a 2000 grand cherokee laredo i seem to have a water leak coming from somewhere under/around the serpentine belt. ive just recently purchased the jeep and did so before finding this forum. now im worried. i must say i love the jeep. hopefully this isnt a big problem any suggestions? thanks
  • cwcwtfcwcwtf Posts: 3
    upon further investigation this seems to be a coolant leak. i havent much here about problems of this nature. anybody else or maybe its just normal maint. problem. thanks
  • paulepaule Posts: 382
    If it is coming from around the serpentine belt, it is most likely a water pump issue.

    You'll need to get under the van with a drop light and look around until you can pinpoint where it is coming from.
  • Hi there aspade,
    My name is Keerit and I am a Marketing Representative with the Jeep Information Center. I’m glad to see that you are doing your research on the 2005 Jeep Grand Cherokee. It’s always refreshing to see consumers taking the effort to make an informed decision on a vehicle. I noticed that you had a couple of questions regarding the fuel efficiency on the 4.7L V8 and the 5.7L HEMI V8 engines available on the 2005 Jeep Grand Cherokee. I can provide you with the EPA’s estimated fuel efficiency ratings for both of these engines. Hopefully this will provide you with a good outlook for what to expect out of the two.

    Would it be okay with you if I joined the conversation?

    Thanks in advance,

    Keerit T.

    I have an 02 GC Laredo 4.7L Selec-Trac 4x4. I have been getting around 16 mpg lately. When new it produced an average of 19-20 mpg on the highway if there was a tail wind the whole way. Ride quality is nice, although I have noticed a tendency for the thing to wander around the asphalt quite a bit. Sometimes it can be a downright handfull and pain in the [non-permissible content removed]. But it absolutely thrives when you leave the pavement. When it hits the back country dirt and gravel roads it feels extremely sure-footed. I have little experience with this vehicle and heavy snow, and I quite honestly haven't thrilled it in a full, off-road experience, so I can't help in either of those areas.

    I have had one issue with this vehicle, but it was a biggie (and covered by warranty). I had to replace the entire rear end last year after 35k miles, including the limited-slip differential. No clear reason why this occurred, but basically all of the bearings wore out and the axles were grinding away into oblivion. Hopefully this is not something that will occur every 35k. I have heard other people describing the same symptoms in the "Problems" forum.
  • Hello there mtngal,

    It’s great to see that you are interested in possibly purchasing a new 2005 Jeep Grand Cherokee! I would like to provide you with information regarding the fuel efficiency for the HEMI engine and any other concern(s) that you may have. The 5.7L HEMI V8 engine has an EPA estimated fuel efficiency rating of 14mpg in the city and 21mpg on the highway. A very respectable figure considering the amount of power that this particular engine outputs (330hp @ 5,000rpm). If you happen to have any other questions, I would be more than happy to help.

    Is the 21 mpg highway likely, especially with a 4WD model? Many years ago I had a vehicle that easily beat the EPA numbers, but my most recent experience has been with the Jeep 4.0L engine. The EPA for highway was 19 for my vehicle, but the only time I ever get close to that is when I'm driving downhill with a tail wind. Otherwise, my all highway mileage runs between 17 and 18, and from the sounds of it, I'm getting better mileage than most. So how realistic is that 21? I sure wouldn't mind getting better mileage while maintaining 4x4 capabilities.
