Faults:

Transmission noise at 8k, 20k and 36k when car was in 4th gear and climbing a hill, just before it downshifted.

Lower intake manifold gasket replaced by dealer and was leaking within 1yr, but dealer and GM refused to cover under warranty because it was reported at 11 months, but had to wait a month to get it replaced on a Saturday. By then, it was 5 days past the 1 yr. mark and said it was out of warranty. By the way, this is where GM lost a customer forever.

Oil pan gasket leaking and since the mechanical engineers designed the engine around it, it'll cost $450 to replace the gasket, since they have to lift the engine to get the pan out.

Water pump replaced.

Battery replaced twice.

Idler pulley assy. seized, broke belt and had to replaced.

Right rear window was intermittent up/down. They pulley assembly in the door was assembled poorly, resulting in cross threading of the pulley wire around the pulley. This was reported twice while under warranty, but each time the dealer said there's nothing wrong with it and it works for us now. Eventually, around 40k miles it stopped working. Just a few months ago I found an assembly at a junk yard that I got for $20, rather than the $265 the dealer wanted.

Faults:

Windshield wipers would not park.

Air-conditioning stopped working.

General Comments:

I really like the car to drive. It has a lot of comfort and is ideal for a long road trip.

Faults:

Had the original power steering pump go out when driving off road 193000mi.

The oil pan gasket just started to leak recently.

General Comments:

This is one of the best vehicles I have owned. It gets excellent mileage at 24 to 30 miles to the gallon.

It is a extremely comfortable ride everything power and still working perfectly.

It accelerates very quickly and has a decent top end speed. The handling is amazing to the touch.

Faults:

Replaced gas tank at 167000 (rust out - NE road salt)

Driver's door and trunk lock cylinders seized up - but remote locks still work.

Slight oil leak gives odor once in a while when it hits exhaust manifold (sounds like this may be common)

Starting to get occasional shutter when shifting.

Replaced A/C compressor with a used one at 170000 (may have been mechanic induced) - coincided with serpentine replacement. Wasn't making noise before belt changed at garage.

General Comments:

Bought car cheap with high miles, but still extremely solid (no rattles)

It has been very reliable - not afraid to drive long distance. Just got back from 750 mile round-trip to Canada.

I have had other cars with the 3.8 motor and highly recommend them. Leaning toward replacing with lower mileage Bonneville (has 3.8) when this car goes.

Faults:

Engine overheated and locked up at 90,000 miles without warning, found to be a cracked intake that I later found out was plastic.

Gasket in rebuilt engine leaked, spewing coolant everywhere.

Knobs on radio cracked and fell off.

Center Console Cup-holder has been fixed several times, but keeps breaking.

Chrome rims started flaking badly at 90,000 and have had to be replaced.

All sorts of electrical problems

--Sunroof/moon-roof no longer works properly

--Cruise control no longer works

--Dual climate control no longer works.

Air conditioning stopped working.

Blower motor went out completely at 100,000 miles (of course in the dead of winter)

Power windows work very slowly and sometimes stick or just decide to go down on their own.

Car pulls to the left.

Spark plug wires went haywire and had to be replaced (they were out of order and caused the car to shudder badly)

General Comments:

This car has plenty of power, but I will never own another Oldsmobile as long as I live.

This car is the reason that I will probably never own another American brand car.
