EGR (exhaust gas recirculation) valves needed to be replaced roughly every 80,000 miles.
Manual crank window on the driver's side stopped rolling all the way to the top at 96,000 miles. I never fixed it. (I just push the glass to the top with my hand.)
Alternator went out at 172,000 miles.
Replaced valve cover and oil pan gaskets at 246,000 miles. Car doesn't lose oil any more!
Drivers seat springs broke at about 250,000 miles. Haven't replaced it yet; I sit on a pillow instead.
Original upper radiator hose blew at 256,000 miles. (My fault; I should have replaced it sooner!)
Second belt tensioner pulley failed completely at 261,000 miles, as did the odometer. I now have to use gallons of gas to estimate the mileage.
Consumer Reports says old Saturns have terrible maintenance reliability. My car is proof that if you maintain it well from the start, you can get great life out of it (262,000 miles and counting). Is it possible that American vehicles are rated below the Japanese because those people who punish their cars are far more likely to buy American?
I still gets 28 miles/gallon in the city, and almost 40 miles/gallon on the highway. The single cam engine with throttle-body fuel injection isn't real peppy, but with gas at $3/gallon, who cares? I've since gotten a Toyota Tacoma truck, so the Saturn is now the perfect backup/commuting vehicle.
