Faults:

Water pump failed around 100,000 miles. Replaced pump and flushed cooling system.

Supercharger bearings worn out at 170,000 miles. Will need to be replaced.

Oil leak from oil pressure sender. Replaced oil pressure sender.

Oil leak from valve cover. Replaced under service recall at GM's expense.

Replaced muffler and resonator due to exhaust leak around 160,000 miles.

General Comments:

The most comfortable and best performing sedan I've ever had the pleasure to own and drive. I can't wait till Buick brings out the next model Regal, if it's anything like this one.

Faults:

Battery at 75,000.

Rear running lights at 75,000.

Alternator around 82,000.

Windshield arms separated from drive motor 85,000.

Valve cover gaskets replaced around 88,000.

Idler pulley for serpentine belt tensioner at about 102,000 replaced due to bearing failure.

Replaced left from hub bearing due to ABS sensor not working around 105,000.

Blower motor bearing noise replaced at 198,000.

General Comments:

Good car for GM. I've been a Toyota man most of my life. Lots of power, room and very comfortable. 29-30MPG highway and 24MPG all around. Car made for assembly line in Canada though and at 203,350 miles interior pieces are falling apart.

No major engine problems yet. I've done a lot of routine work like plugs/wires twice, Serpentine belt and tensioner twice, Replaced all hoses, transmission fluid at 150,000, etc.

Experienced typical problems like upper door moldings on front doors, wiper motor problem, right door sticking, stabilizer noise from rear of car, etc. Car still runs great with lots of power, and I've always used premium. Transmission starting to make a little noise and causing some concern. Will car last to 300,000? I don't think so, but so far it's been a good car. Leaks a little oil out timing chain cover.

Faults:

Minor oil leak when parked on inclines.

Air conditioning shot after about 5 hours straight or so on its MAX re-circ setting, probably my fault.

General Comments:

This car is beautiful with the most comfortable seats available with four wheels underneath. I sat in every car at last year's auto show, and only an Infiniti and a Lexus could compare in the seating department. Room for rear passengers is limited, but the seat comfort compensates. All the controls are well laid out, my only complaint is that the climate control buttons aren't back-lit at night.

In the performance department this car just sings. The motor pulls past most vehicles with barely any throttle. The supercharger is a godsend with the high altitude here in Denver. The ride and handling are generally well composed with longer turns resulting in noticeable lean. The brakes can bring this car to a stop on a dime, and trust me, the ABS works wonders in the snow.

While the interior assembly quality was a little lacking, no major problems build-wise or mechanical have reared their ugly heads.

Faults:

Door trim at top of drivers door continually slides out and drags against rear door. Tapping back with rubber mallet fixes for a few months.

Heater display replaced at 40,000 miles due to being very dim.

Rack and pinion replaced at 55,000 miles. (I had this same problem with a 1987 Buick Riviera at about 60,000 miles.)

Constant oil leak since about 40,000 miles. Have had pan gasket replaced twice, valve cover gaskets, and the manifold gasket replaced. Determined that the leak is now coming from the head gasket, but have not repaired it yet.

Oil level sensor in pan also replaced, although I think it was damaged during the second replacement of the pan gasket.

Water pump replaced and cooling system flushed at 60,000 miles.

The bearing in one of the supercharger idler pulleys froze and blew apart at 65,000. Replaced both idlers and the tensioner on the supercharger belt system.

There is a clunking noise coming from the rear end that I understand is from some worn-out Teflon bushings. Have not repaired yet.

Extended warranty has paid for fixing almost everything. They are refusing to replace the head gasket for now. Warranty company now says that 1qt/2000 miles is not excessive. They now require 1qt/500 miles before paying for repair. Head gasket replacement will be over $700.

General Comments:

Except for the excessive mechanical problems, I would absolutely love this car. It has great acceleration and is a dream on the interstate. Very comfortable leather seats and plenty of leg room in the back seats.

Due to warranty, oil has been changed every 3000 miles or less.

The CD/Cassette sound system is great.

Will probably trade this car off for a newer Regal just before the extended warranty expires at 90,000 miles.
