CAMPAIGN:DOOR LOCK CYLINDER FREEZE UP. GMC Truck GMC Suburban

SUBJECT: DOOR LOCK CYLINDER FREEZE UP

MODELS: 1992-93 C/K MODELS

GENERAL MOTORS HAS DETERMINED THAT CERTAIN 1992-93 C/K MODELS WERE PRODUCED WITH DOOR LOCK CYLINDERS MANUFACTURED WITH INADEQUATE TUMBLER LUBRICATION. THIS CONDITION HAS RESULTED IN AN INCREASE OF LOCK CYLINDER FREEZE UP AND CORROSION.

TO PREVENT THIS CONDITION FROM OCCURRING, LOCK CYLINDER LUBRICANT AND INSTRUCTIONS WILL BE SENT TO ALL OWNERS OF RECORD. OWNERS MAY LUBRICATE THEIR DOOR LOCKS OR THEY MAY ASK A DEALER TO PERFORM THE SERVICE.

THEY ARE WRITTEN TO INFORM THESE TECHNICIANS OF CONDITIONS THAT MAY OCCUR ON SOME VEHICLES, OR TO PROVIDE INFORMATION THAT COULD ASSIST IN THE PROPER SERVICE OF A VEHICLE. PROPERLY TRAINED TECHNICIANS HAVE THE EQUIPMENT, TOOLS, SAFETY INSTRUCTIONS, AND KNOW-HOW TO DO A JOB PROPERLY AND SAFELY.

DEAR <DIVISION> TRUCK OWNER:

AS A VALUED CUSTOMER, YOUR COMPLETE SATISFACTION WITH YOUR GM TRUCK IS OUR GOAL. IN KEEPING WITH THIS GOAL, WE WANT TO LET YOU KNOW THAT WE HAVE DISCOVERED A PROBLEM THAT COULD AFFECT YOUR VEHICLE AND WE WANT TO TAKE CARE OF IT AT NO CHARGE TO YOU.

ON CERTAIN 1992-93 C/K MODELS, SUCH AS YOURS, THE DOOR LOCK CYLINDERS WERE MANUFACTURED WITH INADEQUATE TUMBLER LUBRICATION. THIS CONDITION COULD RESULT IN DOOR LOCK CYLINDER FREEZE UP AND CORROSION.

TO BE ABSOLUTELY SURE THAT YOUR VEHICLE IS TO SPECIFICATIONS, WE HAVE ENCLOSED THE LOCK CYLINDER LUBRICANT WITH THE INSTRUCTIONS TO LUBRICATE YOUR LOCK. THE INSTRUCTIONS ARE LOCATED ON THE BOTTLE OF LUBRICANT AND ON THE REVERSE SIDE OF THIS LETTER. HOWEVER, IF YOU PREFER, YOU MAY CONTACT YOUR DEALER TO SCHEDULE A SERVICE DATE TO HAVE THIS SERVICE PERFORMED FOR YOU AT NO CHARGE. THIS PROCEDURE WILL TAKE ABOUT 10 MINUTES TO COMPLETE, BUT YOU SHOULD ASK HOW MUCH ADDITIONAL TIME YOUR DEALER WILL NEED TO SCHEDULE AND PROCESS YOUR VEHICLE.

THE ENCLOSED POSTAGE PAID OWNER REPLY CARD IDENTIFIES YOUR VEHICLE. PRESENTATION OF THIS CARD TO YOUR DEALER WILL ASSIST IN MAKING THE NECESSARY CORRECTION TO YOUR VEHICLE IN THE SHORTEST POSSIBLE TIME. IF YOU HAVE SOLD OR TRADED YOUR VEHICLE, PLEASE FURNISH US THE COMPLETE NAME AND ADDRESS OF THE PERSON YOU SOLD OR TRADED YOUR VEHICLE TO AND RETURN THE CARD TO US.

WE ARE SORRY TO CAUSE YOU THIS INCONVENIENCE; HOWEVER, WE HAVE TAKEN THIS ACTION IN THE INTEREST OF YOUR CONTINUED SATISFACTION WITH OUR PRODUCT.
