What does the wrench light mean on a ford escape?

The wrench light on a Ford Escape indicates that there is a powertrain malfunction. When the vehicle computer detects a problem with the engine or transmission, it turns on the wrench light and restricts the vehicle's performance. It should only come on if there is an issue, and You should have the car inspected as soon as possible. Having a powertrain failure or powertrain fault tends to happen to older and or higher mileage vehicles and can cause Your vehicle's power components to overheat. If You ignore these warnings, Your vehicle may operate in a defaulted safe mode until the issue has been resolved/repaired.
