The rear coil springs broke at 21,000 miles. One of the broken springs cut into the tire.
The trunk has developed a leak in which water accumulates in the spare tire well.
The left rear quarter panel has started to rust along the edge of the rear passenger door.
At 20,000 miles, the front end developed a rattle in the suspension components (this problem was not corrected even after Ford replaced the front coil springs under a recall).
At 21,000 miles, the rear stabilizer bar had to be tightened down, but there is still a knocking noise in the rear suspension area.
This vehicle was purchased new in 2001 and has not been wrecked or abused.
Nothing has happen to my car like that and it has about 90,000 miles on it now. Driving on Michigan roads 60 miles a day puts a lot of wear and tear on a car. I've had to only do regular maintenance like oil changes.
I have the EXACT same thing on my 2001 Taurus, both rear coil springs broken, found when checking brakes at 55,000 miles, also noticed rust - left rear door and rocker.
