I've read all the reviews and I did have to replace the fuel sensor at about 35000 miles ($450).
The ride is rough without a couple bags of sand in the rear.
I've had virtually NO problems with this car.
The Check Engine light started coming on.
Removed the EGR Valve (in a very easy location) and cleaned out the carbon to good results.
Would I buy it again?
My friend's Mazda Tribute was the same year, got better gas mileage, rode much better and had no problems at all.
Nothing you can do.
The ride was way punishing and replacing a defective part with the same part isn't going to solve anything.
