“I own a 2000 Buick Century with an automatic transmission. It has been repaired three times and is starting to do the same thing it has done the other three times. It was repaired all three times at the GM dealer where I purchased it. Each time it has cost over $600 to repair it. The transmission shifts hard between gears and sometimes the vehicle almost stops moving in traffic.”
NHTSA complaint #10175710, filed 2006-12, 34,000 miles“My car was experiencing an erratic, and harsh upshift when shifting from first, to second, and then to third gear.this problem was due to a faulty pressure control solenoid valve assembly. After investigating I found out that 17 different vehicles have this transmission with the same valve in it, that could have the same trouble.GM has a file on this problem, shtml file=901351”
NHTSA complaint #10070962, filed 2004-01, 54,000 miles“Bought 2000 Buick Century and like many other complaints on the list I have repaired the manifold, water pump, fuel filter at 83,000. I have experienced the whinning and hard shifting the entire time I owned the car. I had intermittent dash light failure which is real dangerous since you can't see the speedometer or anything on the dash. My brakes have failed to brake and I went out into traffic - luckily no accident and there was a median I could steer into! I haven't had a working gas gauge for years. Last night going 70 MPH I felt 3 chugs and lost power. …”

Brought the car brand new and maintained it religiously. Shifting was extremely harsh. Did ok going 55 - 65 miles an hour on the freeway. Non freeway driving it went back to harsh shifting, whining engine, slow acceleration. Took it in to the dealer next am.

After talking with the assistant service manager, they agreed to a 50-50 split. …”
