2016 DENALI/Battery drain/SERVICE Trailer Brake System
2016 Yukon Denali. Vehicle got stuck in the snow. A ball was used in the hitch to pull it out. Next day the battery was dead. After jumping, it had the Service Trailer Brake System message. Didnt think anything of it except now the battery won't hold a charge. It will jump and run fine but left...- Eelimak
