Let me see . . .
2002 Focus ZX3
117,000 miles
Other than normal wear items some of the problems I've had include:
Alternator
Clutch master cylinder, twice
Six rear-wheel bearings (three per side)
Thermostat
T-stat housing
Everything else I've done to the car has been due to normal wear and tear, like brakes and motor mounts. The rear bearings are an anomaly though. I blame it on auto crossing and spirited driving. Also, I've installed a list of performance parts including a cylinder head and camshafts, performance suspension and lots of other junk. Still, the 2.0-liter Zetec burns ZERO oil between 7,000 - 10,000 changes and I AVERAGE around 30 miles per gallon in the two and a half years I've been keeping track. She sees redline (7,200 RPM) every day.
