General Comments:

This Jeep is extremely powerful and quick.

Very comfortable to drive.

Never needed any major work, just routine work for the most part.

Parts are reasonably priced.

I have been able to average 20MPGs at 70-75MPH highway driving.

It does require high octane fuel, but it's worth it.

Faults:

Engine stalls or cuts off for a moment randomly. Removed ECU, and cut 1/8 inch off of cover screws. Hasn't stalled since.

Headlight cells coming loose. Disassembled, cleaned grooves, re-glued with RTV and reassembled.

Gas springs for rear door and window need replacing.

Electric locks intermittently fail to lock.

A/C condensate on passenger floor.

General Comments:

Good gas economy (22-24 MPG on highway).

Wind noise (aftermarket moonroof mostly to blame.)

Good handling.

Faults:

Radiator at about 130,000.

Water pump shortly after.

Starter at 140,000.

Driver seat spring collapsed. Found another at auto wreckers.

A/C compressor bearing went at 145,000.

Wheel bearing worn out on drivers time also around 145,000.

IAC, TPS, and MAP at 164,000.

Alternator at 169,000.

General Comments:

I can't complain about this Jeep. The things that have went bad on it are normal wear and tear parts (for the most part). I tend to go through brakes almost every 18 months, which is fine, and tires almost every year. But that is from constant highway driving. This Jeep performs amazingly off-road in the mud, gravel, and rocky terrains. The snow and ice are also no competition for the Jeep as well. Even when I have to stop in the slick snow, the ABS rarely kicks it.

I added some extras to my Jeep, including a K&N cold air intake system, 62mm throttle body, Gibson exhaust manifold, Magnaflow catalytic converter, Flowmaster Delta 40 Series Muffler, and 3 inch exhaust piping. It definitely helped give the I6 a lot of extra torque.

All in all, the Grand Cherokee runs great. No leaks, doesn't burn oil, nothing out of the ordinary. I am hesitant to buy another Grand Cherokee since the I6 is not made anymore. These engines are bulletproof and so easy to work on. And the parts aren't too expensive as well. At the same time, I don't beat my Jeep either. I take good care of it. And besides routine maintenance and normal wear and tear, the Grand Cherokee doesn't owe me a dime.

I haven't owned my Limited 5.2 for long, but bought it with a few minor issues that were unknown at time of purchase.

Once it gets to about the half tank area the gas gage goes out of whack, shooting from empty to half to full, turning the fuel indicator on and off, until it gets to just a little below the half tank range and then it works again. I'm thinking it's a float switch, but hoping it's electrical or something with the gage.

Within the past day I got in my jeep to go to work and it started beeping at me and telling me my coolant was low. When I went to fill it however it was anything but low. But once I got it again and started the vehicle the warning message and beeping had gone away, which makes me think there's some sort of electrical problem with my gages or something.

Another annoyance is the leaking sunroof. When I first bought my jeep it was sunny out so I couldn't tell if there was any issues with it. But after a day of heavy ran I got into my vehicle only to sit in a small puddle of water, only on the drivers side seat too! If it rains enough for a long enough period of time it begins to soak the entire surrounding area of the sunroof and begins dripping on other places of the vehicle as well. I'm hoping replaces the weather stripping will help.

General Comments:

I enjoy my limited.

I love the leather seats and the heated seat options.

The stock stereo in it is surprisingly decent, and I especially love the dashboard equalizer and skip and volume features on the steering wheel.

Cruise Control Feature is great!

Heater works great, with an awesome temperature setting feature.

It has great handling, except sharp corners because of its all time 4wd feature.

Surprisingly for a V8 it seems to handle gas relatively well. Although with it's faulty gas gage I try not to let it get low.

It has a lot of get up and go!
