My 2024 GWM Tank 300 has an excessive power usage message on the dashboard

This message will sometimes be seen in the Tank 300 when the battery charge drops below 12.5 volts. This can happen for a range of reasons, which can include that the key fob is too close to the car when it’s not being used (believe it or not). So don’t leave the key anywhere near the car when you’re not driving and see if that helps.

Other causes are accessories like dashcams that are either wired incorrectly or are not playing nice with the Tank’s body computer. You could try to disconnect the car’s battery overnight which may reset the computer to factory settings, but this seems like a pretty common fault with the Tank 300.

Being such a new car, the problem should not be the battery itself, but it would still be worth having it checked as well as the charging system to make sure there’s no problem there.
