"I purhcased this vechicle with the 3.7L and it is a complete dog, has trouble getting out of its own way. Gas milage is not that great. 14 around town 20 on highmway. Engine and transmission combo is not the greatest the transmission shifts oddly slamming into gears from time to time. If I had to do it ove again I would have purchased the 4.7l v/8."
"I have the 05 Limited 4.7. This is my second Grand Cherokee, it is smaller than my 00 was. I run up a lot of miles and this is a "very" comfortable Jeep. I have had no issues what so ever. With the current gas prices I do wish it got a little better mileage, however for the type vehicle it is...21.5 constant avg. is not bad. it has always responded when I need it to, excellent pick up power. I will be another one down the road!"
"I had an '02 Grand Cherokee before this and had nothing but problems - steering and transmission issues - and was glad to get rid of it. I decided to give the '05 a try anyway because I liked the new style. I love the way it looks and the features inside are awesome. I have the Boston Acoustics radio upgrade with Sirius Satellite radio and 6-disc changer, sunroof, running boards, and tire pressure monitor (which is a really good thing to have). BUT, the reliability of the vehicle itself has not been great. The air-conditioning makes a whining noise at about 55 mph when on the second setting (we have the manual air). The dealer says this is a known problem that Jeep had no fix for yet (as of last time we talked to them) and this has been ongoing since the month we bought the car (early '05). This problem definitely impedes the enjoyment of the car. Also, the gear shifter has been replaced twice and the original tires have all been replaced due to several safety issues we had over the time we had the vehicle (inexplicably losing tire pressure - this is where the tire pressure monitor really came in handy). Although I love the car itself, again for the style and features, I wish the realiability was better. I probably will not buy another due to the issues that don't seem to get addressed by the manufacturer."
