The only fault I can truly find with my Jeep is the fact that the gas mileage is not that great. I am only averaging around 15 miles per gallon.
I have been truly happy with my Jeep Grand Cherokee. Other than having a flat tire and taking it in for service (for recalls), I have never had a problem with it and I've owned it almost four years.
It is wonderful in the snow and for hauling items to and from our homes.
It is a reliable car, with a nice ride and good acceleration on the highway.
I used to run regular gas in my 1998 Jeep 4.0L, but then heard that it was a high compression engine. I switched to mid-grade gas (89 octane) and have gotten another 2mpg out of it. The extra miles pay the difference in gas price and this has been proven on multiple tanks of gas. It also quiets the valve tapping. Anyone using super for gas? I guess I'll try that next. Other than that, it's a superb vehicle.
