After having my car scanned the following codes were found C1913 Motor Output of rear steering rack drawing too much amperage close to 20A, this was also causing these codes to set as well, C1686, C1671, C1930. It was recommended to replace the rear rack. at a dealer cost of 9K, and I can't find a used one anywhere. Does anyone know if it's possible to repair just the motor? Any help anyone could provide would be appreciated.
