Door Latch problems of the 2000 GMC Sierra

Stopping to run an errand on the way home from work I attempted to open the driver door of my 2000 GMC pickup. The door which has a power lock would not open. The electric door lock has apparently failed rendering the door inoperative. After a short panic attack, I had to exit my vehicle from the passenger door. The door could not be unlocked from the outside with a key or from inside the vehicle using the manual door lock slider bar. This is a severe safety hazard and should demand an immediate recall to ensure a failure of the power lock fails safe. As a safety engineer, I believe this could result in a fatality by someone not being able to exit the vehicle.

During a rain and then freeze in michigan, the driver side door latch fails to operate properly. By failing to operate, once open it will not latch until it thaws out. It has happened to me twice so far this 2004-2005 winter. GMC customer service has been contacted as well.

Passenger side door lock would not open with the remote or manual inside or outside door handles @37000 miles had to put key in door lock and hold key to extreme left and pull handle at same time to get passenger out. I think this is a safety issue. It is still broke.

While coming down a hill put foot on brakes, and it felt like pushing on a brick wall. Consumer proceeded through a stop sign. Consumer has to press brake down twick before vehicle will stop. The brakes failed twice. The steering column makes a grinding noise when turning. Horn failed. Keyless entery failed. Door locks failed. Interior lights failed. The fan in the front end is very loud. The speedometer is inaccurate. The power steering pump shaft broke.
