GWM Tank 300 2026 Problems

More than a few Tank 300 owners have complained about multimedia and electronic glitches. It’s likely to be a software issue and GWM is doubtless working on fixes and patches to make it all work properly. This can take time, however, and owners can be understandably impatient when their brand-new car doesn’t work properly.

Just be sure you keep your dealership across all the problems you’re having. That way, there’s a paper-trail that will support your claims that all these problems occurred within the warranty period and are, therefore, GWM’s problem, not yours.

GWM is by no means the only carmaker in this situation, and the sheer complexity of modern vehicles and their multitude of electronical functions appears to be part of the problem.

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.
