2002 Jeep Liberty

I have read several messages reguarding the gas mileage of the Liberty.
I have 110,000 on my Liberty and am still getting between 14 and 16
miles per gallon. Never did get better gas mileage. I use fully
synthetic oil and that still did not help.
I have had a problem with this vehicle since about one month after I
purchased it. The transmission would, at will, down shift into second
gear. Try travelling 70 miles per hour and have that happen. It feels
like someone is slamming on the breaks. It took the dealership 8 months
to find the problem. Since this was fixed, or so they say, the vehicle
hick-ups when moving. It also slams into first gear seconds after you
come to a stop. I was told that unless the problem throws up a default
code, they have no way of diagnosing the problem. :shakehead So I have
had to put up with this. Also I had to have the brakes done shortly
after I had 12,000 miles on the vehicle. I was told at the dealership
they are a normally replacable item and they were not covered under
warrenty. I had to pay over $400.00 for that repair. Now the vehicle is
paid off and every week I have a different problem. Last week it would
not shift up from second gear when excellerating from a stop. And this
week it will not run. You can start the vehicle, but as soon as it
starts warming up, the engine shuts off and you cannot re-start the
vehicle. I tell you, with all the problems I have had with this vehicle
and all the run around I have had to put up with from Chrysler
dealerships, I will never purchase another Chrysler product. As soon as
I get this new problem repaired, I am trading in this vehicle and good
riddence to Chrysler. :banghead:

 

As the owner of several Chrysler vehicles over the last 25 years, I can
assure you I've had very good success with their vehicles, particularly
since '86.

All I can suggest is to not buy a new mechanical design in the first two
model years. Was 2002 the first year or second of your Liberty?
