2003 Jeep Grand Cherokee Laredo 4WD 4dr SUV (4.0L 6cyl 4A)
Our Jeep started bucking and becoming undriveable at 5000 miles. This is intermittent and has caused several delays on family trips. The manufacturer just says, "bad gas". They did extend our warranty to 70,000 miles, free. Big deal, the car is not reliable. They have yet to find the problem. We are going on three years of this. Tomorrow we go to "Lemon Law" court with the manufacturer. Wish us luck.
When the car bucks violently, it feels like a tire going flat or out of round. When you pull off the highway in a bad part to town, RELIEF! The tires are fine it's the engine that's causing the problem.
To retain the Trail Rating, make sure there's a service center at the end of each trail.
