I have had no major mechanical problems with the Jeep.
Make no mistake, if you are buying a Liberty you are buying a truck-like ride. The Liberty does not "ride like a car" as advertised. There is a lot of wind noise while driving over 70mph on the highway.
I have taken the Jeep off road on several occasions in northern Michigan and it handles beautifully. It is amazing the size of hills and bumps that the Jeep can handle effortlessly.
The interior of the Liberty is nice with the leather and sunroof. The only factor I do not enjoy is the lack of leg support on the seats, they are very small and do not support your entire legs.
Overall, the Liberty does everything it is supposed to do. It is adequate on the road, and excellent off of the road. I however, will probably not buy another Jeep because I hardly ever go off the road and want to find something that rides more like a car on the highway such as the Honda Pilot, Chevy Equinox, or Toyota Highlander.
The Liberty is thirsty for gas, I'm not complaining, you have to expect that when you buy a V6 4WD SUV. Also, I once hit a deer with the Liberty and the Jeep handled like a tank. I have felt very safe in this car as far as impacting other objects is concerned.
However, one time I did end up off of the road and in the ditch when I was on a sheet of ice, even with 4WD engaged.
Overall, it's a good vehicle, but not great.
Thank you! I was beginning to think I was crazy, complaining about the wind noise and the leg support and the lack of foot space for the driver's right leg. I bought mine yesterday and was so excited--it's such a nice car with lots of goodies, but I'm returning it tomorrow. I think driving it 500 miles a week and only the occasional off road trip will be really trying...
