the most common issue encountered with a GMC Acadia is often a drained battery, which is considered a replaceable component that may need to be changed occasionally. If you find yourself frequently dealing with dead batteries or if replacing them doesn't fix the issue, it might signify a larger underlying problem. Should the alternator fail, it may result in the battery not getting charged. This could be due to issues with the rotor/stator assembly or the voltage regulator. The most effective method to diagnose whether the problem lies with the battery or alternator is to conduct respective tests on the vehicle.

Water leaking from a roof or window can lead to corrosion in your fuse box or BCM. I am currently experiencing this issue, as my alternator's L terminal is no longer functioning. Additionally, I am receiving error codes related to the door lights and the bus A not responding. I am planning to remove and repair my BCM, and I have already cleaned up the fuse box. If the alternator isn't charging properly, I will replace it once more. I have already had to install two alternators and two batteries before purchasing this vehicle.
