Traction light comes on and off after I hit a curb. Also the car starts breaking wierd when going over 40mph

Hello, diagnostic testing of the "chassis" related components such as the anti-lock brake system and traction control system will reveal diagnostic trouble codes that will lead you to the source of the failure you are experiencing. I am certain something has been bent or damaged due to the curb hit. Do not drive like this! You can be causing extreme tire wear and components could be damaged to the point of being severely broken and in need of replacement for safe operation. This will not be a difficult diagnosis, but may be expensive to repair depending on the extent of the damage.
