Q: the enhanced traction control will not shut off

Hello. It sounds like when you have the traction control on that it is kicking in. The most common cause of this would be if there are mismatched tires on the car. If this is the case then the computer will always see the wrong wheel speeds which will cause it to power down the vehicle. If the tires are all the same size and if the wheel speed sensors are good then the computer will need to be scanned for codes to see why the computer is turning this system on. It can be a bad computer, a yaw sensor, or another electrical issue. If you need to have this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the loss of power firsthand for an accurate repair.
