2019 GMC SIERRA DENALI Engine Problems

I RECEIVED A RECALL NOTICE MAY 2019 FROM MARYANN L. COMBS, VICE PRESIDENT GLOBAL VEHICLE SAFETY. THE LOCAL DEALERSHIP SAID PARTS WERE NOT AVAILABLE AT THAT TIME. A FEW MONTHS LATER, STILL NOT AVAILABLE AND TODAY, FEBRUARY 25,2020 THEY ARE STILL NOT AVAILABLE AND IT SEEMS THEY MAY NEVER BE AVAILABLE TO VEHICLES IN THE "SOUTHERN" STATES. MY TRUCK TRAVELS TO MN, MT, ND ON A REGULAR BASIS AND THE PROBLEM IN QUESTION NEEDS TO BE FIXED TO KEEP THE ENGINE WARM AT BELOW ZERO TEMPERATURES. NHTSA CAMPAIGN ID NUMBER IS 19V328 AND RECALL NUMBER WAS N182206311. PER THE LETTER FROM MS. COMBS USE OF THE CURRENT ENGINE BLOCK HEATER CABLE COULD RESULT IN AN ENGINE FIRE.

WHEN I PURCHASED MY TRUCK ON 08/17/2019. THE WINDOW STICKER SAID MY HEATER BLOCK WAS DISABLE. THE SERVICE DEPT. SAID THERE IS A RECALL ON THIS. I CANNOT GO IN COLD WEATHER UNTIL THIS IS RESOLVED. CAN YOU TELL ME WHEN IT WILL BE RESOLVED.
