Consumer Description

THE NEW GM 2021 TRAILER LIGHTING MODULE AND/OR SYSTEM IS DEFECTIVE. IT FAILS A PRE-CONNECTION TEST WITH TESTER, GIVES "CHECK TRAILER WIRING" WARNING ON DASH WITHOUT A TRAILER CONNECTED AND TURNS OFF ANY TRAILER LIGHTING CONNECTED WITHOUT WARNING ON THE ROAD, WITHOUT BLOWING A FUSE. THIS PROBLEM IS MUCH LIKE THE TSB REPORT #20-NA-198 FOR EARLIER MODELS. THIS ISSUE WAS ADDRESSED BY THE DEALER BY REPLACING THE MODULE, BUT THE PROBLEM HAS RE-OCCURRED WHILE ON THE ROAD CAUSING A ROAD SAFETY ISSUE (NO TRAILER LIGHTING), SOME TIMES WITHOUT WARNING. THE DEALER DOESN'T KNOW WHAT ELSE TO DO AT THIS POINT.
