Faults:

The plastic intake manifold broke at 46,000 miles and at 101,000 miles. The 4 struts and rear springs had to be replaced at 48,000 miles because the car bounced so bad. The transmission developed a slip or shutter under any hard acceleration. Didn't fix it, I lived with it because it was too expensive to repair. The list goes on and on. I threw more money into the car than what I payed for it.

General Comments:

This car was babied and still looks brand new, but is ready for the junk yard because of GM's poor mechanical design.

Stay away from this money taker-Worst repair record of any car I've owned-Junk!!!

Faults:

Engine manifold gasket developed a leak into the engine, and the engine seized due to the leak. This is a manufacturer defect due to installing a plastic manifold, causing it to melt and develop a leak, blowing my head gasket at 135000. In all, the only problem was the leak.

I'm now installing a 2000 Impala LS engine in it; it is cheaper than an actual repair.

General Comments:

I would try this solution to problems with the plastic intake manifold.

It appears they do not sell direct, but can direct you to a distributor.

Faults:

Air Conditioner Compressor failed at 120,000 kilometers.

Driver side power window motor failed and had to be replaced at 110,000 kilometers.

When hot the car vibrates when accelerated if transmission is hot. Service Technicians have been unable to determine the problem.

Traction control kicks in rather early and is quite loud.

This is a great highway car and would buy another just for the ride.

Wind noise is rather high and if windows are opened at highway speed, don't fully seal when closed.

Faults:

The only problem I have had is in the automatic temperature control for the heat and air conditioning. It is slow to respond to temperature changes. However, this could have been caused when my son connected a CD changer to the radio.

With the Gran Touring Suspension, this is a great car for around town as well as on a trip. It is very comfortable, yet also responsive.

I filled the tank today and got 26+ miles per gallon, mostly local driving with not much use of the air conditioner required. Using the air conditioner more, it usually gets about 25 locally. (The better the brand of gasoline, the better the miles.) I have gotten as much as 36 on a trip and usually average about 31 doing around the speed limit and using the air conditioner. For a large, comfortable car, I am well pleased with the mileage.

An older mechanic friend told me I could expect this kind of mileage and that this is pretty much normal for this car.

I'm not enthused about the intake manifold being plastic. However, many cars are now using plastic intakes. Just keep an eye on the coolant, which one should do anyway.
