What does ECT Power light mean?+
Sounds like a fault in the electronic traction control. You will probably need to have this checked by a dealership or a competent garage that has access to the parts.
is it a major car repair how long before you get it checkout before it harms your car
i dont think this is traction control. I believe it is your engine coolant temperature. I would say to get it checked out soon so you dont overheat and cause other problems. Make sure the coolant is full before you drive it. Hope this was helpful
