2000 Chevrolet Silverado complaints

I WENT TO EXIT MY VEHICLE, IN PARK, WHEN I BUMPED THE #2 MEMORY SEAT SETTING ON DOOR. THE SEAT WENT ALL THE WAY FORWARD. I WAS UNSUCCESSFUL AT GETTING IT TO STOP OR GO IN REVERSE WHILE IT WAS MOVING FORWARD. IT WAS HARD TO GET OUT OF THE SEAT. MY RIBS WERE SORE FOR 1 DAY. THE SEAT WAS NEVER PROGRAMMED BEFORE THIS. I BELIEVE THIS IS A DANGEROUS FACTORY SETTING. I CALLED CHEVROLET CUSTOMER ASSISTANCE AND THEY WERE USELESS.

SEAT BELT WON'T ENGAGE EVEN WHEN BRAKES HAVE BEEN APPLIED AND THE REAR WHEELS HAVE LOCKED UP. *AK

CHEVROLET HAS DENIED THAT THEIR 99 AND 00 CHEVROLET SILVERADOS DO NOT HAVE A PROBLEM WITH THIER NEW ENGINES. I KNOW OF NUMEROUS OTHER OWNERS WHO HAVE THIS PROBLEM WHICH CHEVROLET ACKNOWLEDGES AS A NORMAL SOUND. I HAVE BEEN TOLD BY THE DEALER THAT THE TRUCK CAN NOT BE FIXED BECAUSE THE NEW ONES MAKE THE SAME NOISE. I HAVE DRIVEN OTHER COMPRIABLE TRUCKS AND THEY DO NOT HAVE THE ENGINE PING/KNOCK. THE DEALER ALSO SAID THAT THE NOISE WILL EVENTUALLY GO AWAY, BUT I HAVE SEEN TRUCKS WITH 19000 WITH THE NOISE CONTINUING. THIS PROBLEM COULD INCREASE EMMISIONS IF IT IS INDEED A PING/KNOCK. IF THIS PROBLEM PERSISTS WITH NO FIX FROM CHEVROLET, I COULD HAVE ENGINGE DAMAGE CAUSED BY THE PING/KNOCK THAT WILL NOT BE COVERED BY THE WARRANTY. THANK YOU FOR YOUR TIME.

DEALER HAS WORKED TO GET THE TRUCK REPAIRED BY REPLACING FRONT TIRES TWICE, ALIGNING THE FRONT END. THEY HAVE PROVIDED GREAT SERVICE. THE TRUCK WAS DELIVERED IN DISREPAIR FROM THE FACTORY.

BRAKE PEDAL WENT TO FLOOR, ANTILOCK BRAKES ENGAGED, ON DRY PAVEMENT AT 30 MILES PER HOUR. HAS HAPPENED FOUR TIMES. THREE TIMES ON ROUGH PAVEMENT, ONCE ON DRY. DEALER REPLACED EBCM AND BRAKE PRESSURE MODULATOR. AT NEXT INCIDENT DEALER REPLACED BRAKE MASTER CYLINDER. NOW BRAKE PEDAL SLOWLY GOES TO FLOOR AFTER STOPPED IN DRIVE POSITION.
