2007 Jeep Liberty Limited 4dr SUV 4WD (3.7L 6cyl 4A)
Well, we now have had problems with a window regulator. Luckily, the dealership replaced one with the new updated model that corrects the defect. Although the dealership would not use the word defective. Our mileage continues to be great after the syn lubes, PI in the tank, Costco Michelin tires with nitrogen. 25 mpg not too bad for 4x4. We cannot thank our Master mechanic enough for recreating our Jeep with great parts like Bosch Platinum+4 100,000 mile spark plugs and Amsoil synthetic lubes. We change oil only once a year now, we like that. And under the Magnuson-Moss act of 1974 syn. extended oil changes cannot void warranties. If the dealership says otherwise they are lying.
Handling is superb! By throwing crap Chrysler parts and petroleum oils and using good ones the mileage is much better from 16 to 25mpg, and a lot of extra power. Much more fun to drive. Quick, nimble and a real keeper.
The window regulators are defective, Chrysler knows they are defective and has improved ones that last forever now. Chrysler should be honest enough to replace the defective ones at no charge to customers.
