I recently began getting “service trailer brakes” on my screen. This only occurs when towing trailers and not a single trailer. These trailer do not cause the alarm on similar vehicles either. I took it to the shop who didn’t look at my vehicle for a week. During this time my cell booster was plugged in the whole time, which drained the battery. The tech called and said it was a low voltage issue. I told him to disconnect the cell booster and charge the battery. He did and no more low voltage. Then he stated that there was no problem with the trailer brakes. I asked how that system was tested and he said they didn’t ave a way to test it. Hmmm. There are number of these complaints all over the internet with the same “code” and GM is not able to, and unwilling to diagnose it and correct it.

I RECEIVED A RECALL NOTICE #N182206311-04: SAFETY RECALL - DIESEL ENGINE BLOCK HEATER CORD. THE NOTICE SAYS THAT I NEED TO GET THE CORD AND HEATER REPLACED WITH PART NUMBER 19419326 AS I RISK AN ELECTRICAL SHORT DAMAGING ENGINE COMPONENTS OR AN ENGINE COMPARTMENT FIRE. I DO NOT WANT TO RISK THAT. I FIRST RECEIVED THE NOTICE IN JANUARY, 2020. I WAS TOLD THEN THAT THE PARTS ARE ON BACK ORDER AND THAT THEY WOULD CALL ME WHEN THEY GET THE PART IN. NO RETURN CALL. I HAD ANOTHER RECALL NOTICE SINCE AND TOOK IT IN TO THE CHEVY DEALER TODAY AND WAS REMINDED OF THE PRIOR RECALL NOTICE REGARDING THE BLOCK HEATER. I ASKED TO HAVE IT REPLACED PER RECALL NOTICE. THE DEALERSHIP IN HENDERSON, NV CAN'T GET THE PART BECAUSE GM WILL NOT SHIP IT TO NEVADA. I CALLED GM TODAY, 4/16/20, AND SPOKE TO [XXX], AND THEN TO HER SUPERVISOR, [XXX]. I EXPLAINED THAT MY WIFE AND I ARE RETIRED AND DRIVE THIS VEHICLE IN STATES AND AREAS THAT ARE EXTREMELY COLD, I.E., WE HAVE A CABIN AT PANGUITCH LAKE, UT (MOUNTAIN LAKE) WHERE WINTER TEMPS. GET BELOW ZERO. WE GO THERE EVERY MONTH, YEAR ROUND. WE GO TO IDAHO TO VISIT CHILDREN WHERE TEMPS APPROACH SINGLE DIGITS. I GO HUNTING IN NEVADA AND COLORADO MOUNTAINS WHERE TEMPS. GET BELOW ZERO (I USE A GENERATOR TO PROVIDE THE POWER TO HEAT THE ENGINE BLOCK). I NEED TO HAVE THIS RECALL PROBLEM TAKEN CARE OF FOR THE SAFETY OF MY TRUCK, MYSELF AND FAMILY, AND OTHERS WHO MAY BE IN CLOSE PROXIMITY TO ME SHOULD A PROBLEM FLARE UP WHILE DRIVING. [XXX], A SUPERVISOR AT GM, IS ADAMANT THAT I WILL NOT BE ABLE TO GET A NEW ENGINE HEATER CORD AND HEATER. I WAS TOLD IT'S THEIR POLICY TO ONLY SEND UNITS/PARTS TO COLD WEATHER STATES. SO IF I LIVED IN RENO, NV WHERE WINTERTIME TEMPS. ARE CONSISTENTLY BELOW 20 DEGREES, I WOULD NOT GET AN ENGINE BLOCK REPLACEMENT HEATER AND CORD. I PAID TO HAVE A WORKING ENGINE BLOCK HEATER AND CORD WHEN I BOUGHT THE TRUCK. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
