It's essential to understand the wrench light and what it signifies to ensure that you take the necessary measures to address the issue.
So, what does the wrench light on Ford Fusion mean? The wrench light indicates a problem with the powertrain of your vehicle. It can signify several issues, ranging from minor to severe.
