In Feb. 2004, the AC condenser went bad at 148,000 miles. This was a $625 fix, and was retrofitted. The retrofitted unit blows 38 degrees. It can pull a lot of power on the lowest setting, cycling on and off, so I run it for shorter times on a higher setting.
The crank seal, cam seal, and timing belt were replaced at the same time as the AC unit because the car was smoking. $250 for mostly labor. No more smoking. Also, the hood latch became impossible. New parts and labor were only only $10 (done at the same time that the AC condenser). At the same time, I replaced a headlight and turn signal light myself because the lense had suffered considerable sun damage. $170 for parts. The handle for the driver's door had come loose. I fixed it myself for free. Also, oiled the door hinges, which had become sticky. Now very smooth.
At 130,622 miles I had to replace a lug nut. $26.00 The original hub caps kept flying off, so I got aftermarket ones, for $60 and have had no problems ever since.
I also have replaced the timing belt at 116,831, and I had a tuneup at 108,617 miles. $142.
I live two blocks from the ocean and have some rust issues. Especially the windshield seal on the driver's side. I keep this maintained with putty and paint. It's right above many electrical parts. I've had four volvos, and they all rusted in the same spot!
I had brake rotors and calipers replaced at 121713 miles. No problems ever since. $524.
Electrical issues that are more annoying than expensive. The overdrive began to stick on at $145,000 miles. The repair was $60.
