2004 Jeep Grand Cherokee Limited Rwd 4dr SUV (4.0L 6cyl 4A)


This will be my 4th Jeep and last. Purchased new and ran great for first 10,000 miles. Started to have rough idle problem when in drive. Had 4 different dealers work on it with no luck. They just say V8's idle rough in this vehicle because idle RPM is set too low for lower emissions. Can't change computer settings. What bull! If buying this vehicle used, look for one with at least 15,000 miles. This idle problem does not set in until later. Very smooth running V8 but idle at red lights or traffic a joke. Passengers will ask you whats wrong with your car? Brakes also need frequent work. Only buy this vehicle with a power driver seat.

Best Features

Flat fold down rear seats. 10 disk CD changer. Leather power seats very comfortable.

Worst Features

Engine idle speed at stop needs to be higher RPM. Better brakes. Better city fuel mileage. Really drops from highway mileage. Drops 30%.
