No matter what car you buy, it's going to have it's share of issues. Honda's vtech solenoids like to go out, bmw's window regulators, Toyota's can have issues with the computer that ends up affecting the cooling fan so the car overheats, buick transmissions love to **** the bed, ford Taurus transmissions like to fail right after the warranty expires. Sometimes these issues happen no matter what type of maintenance you do, even strictly by book. Much of what you've replaced are considered wear items. You've already invested many dollars to get your jeep running correctly, I've been down your road and I'm still going down it every once and awhile. Cars break. Think about your decision before buying another car or truck, because you may end up spending just as much on another vehicle.
Some say a comet will fall from the sky.
Followed by meteor showers and tidal waves.
Followed by faultlines that cannot sit still.
Followed by millions of dumbfounded dip****s.
