Tl*the contact owns a 2001 pontiac bonneville. While driving 15 MPH, the steering column began making a grinding noise at 52,000 miles. The contact took the vehicle to the dealer and they pulled out and lubricated the steering column, which temporarily corrected the failure. At 67,000 miles, the grinding noise recurred. The dealer replaced the steering column. At 78,000 miles, the failure recurred. Currently, the dealer is refusing to make any more repairs to the vehicle. The current mileage was 78,000 and current mileage was 52,000.

Dt*: the contact stated two years ago the steering began to make a grinding noise while driving. The vehicle was taken to an independent mechanic who determined the intermediate shaft had failed which interfered with the steering. The mechanic replaced the shaft, and explained it was unusual for this part to fail. The manufacturer was contacted, and a complaint was filed. Two years after the replacement the same part needed to be replaced again. Updated 05/30/2006.

Dt: the consumer was driving home from work and the back driver's side window fell down in it's window slot halfway without any indication. The driver heard air and wind coming into vehicle and discovered that the power window had opened halfway by itself. The consumer took the vehicle to the dealer who replaced the window regulator which failed. Afterwards, the front driver's side power window has failed and the window will not go up by itself without manually helping to maneuver it back up. There is a grinding noise. The second failure has not been repaired or taken back to the dealer as of yet.

During "cold" acceleration and deceleration, the transmission in the 3.8l v-6 engine in the 2000 pontiac bonneville runs so smoothly that it is almost impossible to feel or hear the transmission shift between gears. However, during "hot" acceleration and deceleration, the transmission shifts so roughly and violently that it is startling to the driver and it seems that the transmission is failing. The shift is very harsh. It bangs, bumps, shudders, slips, and grinds its way up and down through the gears. It is not healthy for the transmission or the rest of the engine. I have seen and heard many similar complaints about this happenstance and wholeheartedly believe that it is the sole responsibility of the manufacturer to recall and repair any and all transmissions that are experiencing this possibly life threatening design flaw and manufacturing failure. (because, in many cases, drivers have actually had their vehicle stop due to the defect in the transmission.) a remedy has been released...fix the pressure control solenoid...which is a manufacturer defect. However, the consumer is billed for this repair and it can cost above $400.00. A manufacturer defect should be recalled, repaired, and paid for by the manufacturer. Don't let the manufacturer get away with charging consumers to fix a flaw and defect that most likely occurred in the factory while the vehicle was in production. My vehicle was "checked" twice by service center at the dealer where it was purchased. I was told "nothing is wrong with it...this transmission is a sport transmission...it was built to shift with a "punch." however sporty a vehicle or transmission, a driver should not feel as if the transmission will fall out as it shifts.*note* in the "vehicle information" section, you will notice that I noted the failure occurred at 10 MPH and at 40,000 miles. The failure occurs at any speed. It was occurring when I purchased the car, so I imagine it was occurring before I purchased the car.

Tie rod ends had to be replaced at about 15k miles, again at about 25k miles. Car now has 64k miles and needs to be replaced again. Also, I have had to have the steering shaft lubricated and/or replaced 4 times due to the clicking/grinding noise caused by defective shafts.
