EGR valve doesn't work (doesn't affect performance of the car).
Rear brakes lock up when it's damp out e.g. raining.
I'm very pleased with my car. It's pretty stylish for a Cutlass Ciera and it's in peak condition, both mechanically and cosmetically.
The 3.8L V6 comes in handy when accelerating or passing on the highway, it really feels and drives like a V8... and it gets good mpg. However, it's a bit sluggish when accelerating from a dead stop.
A great car to drive and own.
Just bought an 88 Ciera 2 months ago and problems aside it's a great car. The alternator has just gone bad (bearings) and I just decided to let the leaking "heater core" go until the weather warms up... our rear breaks also lock up on the passenger side when it rains... can freak you out if you're not careful.
