More like what hasn't gone wrong with it!
-Oil pressure warning light works intermittently
-Interior lighting (centre console/heating controls) does not work, main beams come on every time you indicate (until the switch burned out 2 weeks ago).
-Rear foglights do not work
-Heated windscreen has stopped working
-Burns a lot of oil
-Engine never seems to warm up properly
-Tracking always needs adjusting
-Wishbones (?) on front suspension wear out quickly
-Rear shock absorbers wear out quickly
-Drivers seat subframe snapped
-Gearbox problems, difficulty engaging 3rd gear and noisy when in neutral and engine at idle speed
Very poor fuel economy (23mpg on long runs), acceleration is poor too (due to poorly-suited gear ratios).
The seats are very uncomfortable, there is a distinct lack of headroom (I think due to the poor design of the tilt & slide sunroof housing in the roof). The heater blower is very weak (I would be lost without an electrically heated windscreen!) and the air direction controls are poorly designed so that it is impossible to direct the air exactly where you want it to go.
Basically a very poorly designed car, not a patch on my previous Escort, a 1988 1.4LX.
