Front Seat Power Adjust problems of the 2000 Chevrolet Express

Driver's side power seat continued to fail. The part was replaced three times. However the problem recurred.

Failure of driver seat power adjustable seat mechanism. Two rear pivots are failing. The steel of the upper pivot link is fatiguing until complete failure. Seat can move during rapid turning or hard bteaking. Seat rotates about front pivit points. We have had vehicle about 2 1/2 years and have had to replace the seat adjust mechanism twice.

The rear brackets on the driver's power seat adjuster assembly completely broke. The whole seat now pivots forward on the front brackets. We brought it to the attention of our local gm service center and were told it would cost nearly $900 to repair. We feel this is a safety issue and would like your help in identifying the history of this type of failure. What steps should be taken with the manufacturer to have them repair this at their expense?.

My wife was sitting in the driver seat of the van. The van was parked. Her leg made contact with the power seat control moving the seat forward and trapping her in the vehicle with her knee stuck under the dashboard. The seat would not return to it's original position and there is no release mechanism other than the power control knob. The seat was installed by mark iii conversion vans and sold as new by the d & c Chevrolet gm dealer.

While driving track bolts broke for the second time. Contacted dealer, and the dealer cannot find a remedy. The power seat anchor broke and detached from the seat track while driving almost causing loss of control.
