dead battery

  1. Terrain General Discussion
    Hello All, I just had to replace the battery on my 2016 Terrain Denali. The previous owner replaced it less than 3 years ago. Is 2-3 years the average battery life? Also, I have a short 10 minute commute and run the radio while on my lunch break in my car. Could this be the cause of the battery...

    The lights on my (2018 GMC Terrain SL) AWD toggle switch won’t shut off when the car is completely shut off and it’s draining my battery. Anyone else experienced this? Any suggestions on how to fix it?
