Rear seat belts replaced twice because they either didn't retract or release.
Fuel filler door solenoid replaced because it decided to stay shut one day.
On third set of tires, but learned to buy non-Goodyear tires for better wear and performance.
The front doors "breathe" when windows are raised or lowered. I have been told by three dealers that this is normal, although I've never seen another car do this.
Traction control system only seems to tell me when I've lost traction, but not assist me in regaining it.
Left outside mirror was replaced four times by three dealerships due to severe vibrations at speeds as low as 30mph. Fourth vibrates too, but at least I can see the images in the mirror.
The headlights "blink" when turn indicator is used or brakes are applied. Current dealership is clueless as to why this occurs.
Climate control system doesn't like cold weather and doesn't work until the car warms up, then the display mysteriously lights up and the system comes to life.
Car drinks coolant/antifreeze. No leaks can be found, under any circumstances, ever. Replacing 1-2 quarts every two months, no matter what time of year it is.
I get great gas mileage, city and highway, averaging 22mpg.
Great handling and performance.
Seat ergonomics are terrible.
Oldsmobile could have had a great car if they had paid more attention to detail and customer service.
Haven't found a dealership/service department that I'm confident is competent, or that understands the car.
As I have read other reviews about intrigues, try to look at the HVAC central unit's ground wire. check if the screw ground it to the body is loose or detached, that may cause the headlight and thermostat problems.
Your coolant loss problem is most likely a leaking intake manifold gasket. This is problem all GM push-rod V-6's (3.1, 3.4, and 3.8) will face around the 100,000 mile mark. Once you take care of that, these motors are an easy 200,000 mile motor.
