NHTSA Complaint #11101732 — 2013 CHEVROLET AVALANCHE 1500

THE ADHESIVE SECURING THE 4 PIECES OF DOOR TRIM IS BREAKING DOWN AND THE TRIM PIECES WILL EVENTUALLY FALL OFF ON THEIR OWN, A POTENTIAL HAZARD TO OTHER MOTORISTS DEPENDING ON WHEN AND WHERE IT HAPPENS. THESE ARE SUPPOSED TO BE A NO MAINTENANCE ITEM. REPORTED TO CHEVROLET, CASE # 8-4199057982, AND THEY DO NOT SEEM TO BE CONCERNED THAT THIS "LIFE OF THE VEHICLE" INSTALLATION IS DEFECTIVE AS THE 3 YEAR BUMPER-TO-BUMPER WARRANTY IS EXPIRED. AS A PRINCIPLE ENGINEER IN BOEING'S RESEARCH AND TECHNOLOGY DIVISION (WE TEST STUFF TO MAKE SURE IT'S SAFE), MY INFORMED OPINION IS THE DEFECT IS CAUSED BY POOR SURFACE PREPARATION PRIOR TO BONDING, ADHESIVE MATERIAL USED PAST IT'S WORKING LIFE, ADHESIVE MATERIAL PAST ITS SHELF LIFE, OR USE OF AN ADHESIVE MATERIAL WHICH IS NOT DESIGNED FOR THE INTENDED ENVIRONMENT. AS THIS SAME TRIM IS INSTALLED ON NUMEROUS CHEVY, GMC AND CADILLAC TRUCKS AND SUV MODELS ANY CAUSE OTHER THAN THE FIRST TWO I LISTED WOULD INDICATE A PROBLEM WITH NUMEROUS VEHICLES.
