Previous owner's records indicate electronic issues with the transmission and brake calipers, and that the car was maintained regularly until I bought it for $1,600.
The alarm does not engage.
The remote does not work. This is likely a problem with the car.
The AC does not work. The car holds a charge, but the compressor disengages after a few minutes.
The climate control is inconsistent and quirky, occasionally fails completely.
The driver's side power seat does not move forward/back, and the back rest does not recline up or down. The seat is stuck all the way back and the recline is also stuck, and cannot be forced by hand to new positions. I can deal with it because I'm tall, but other people have trouble driving it as a result.
The power antenna was broken. I bought a new antenna/mast for $17 and installed it myself in 20 minutes (the plastic piece that hoists the antenna up had broken off inside the motor).
The ABS light is on, and the ABS/traction does not work except when it is very humid out. This caused the speedometer to occasionally fail as well. I removed the unit and sent it to one of the many services that repairs them.
The front left brake caliper seized the same day I bought it, and cost $120 to replace.
The brakes vibrate very badly (a problem noted in the P.O.'s records at 100k as well). I should have replaced the brake shims, but the problem went away on it's own after a few thousand miles.
At 165k the welds on the driver's side door hinge broke and the door made a loud cracking sound when moved. I do not know if it was a critical repair, but it cost $400 to have a professional mechanic and welder repair it.
