Hey CMF help me out, my car is acting up. Now this is going to be the second time i took the car back to the dealership for the same thing that keep popping up on the indicator saying reduced engine power, service esc and then says esc off followed by service traction. The first time this happened the dealership reset the computer and after 2 days problem never reoccurred. So i get the car back and 1 1/2 days it starts again same messages indicating. anyone what this is?

The Service ESC is more than likely due to the throttle control codes. If there are throttle control codes the engine control module can't perform its part of the function by reducing torque. The ECM sends a message to the EBCM that it can't do its job and the EBCM sets the Service TC and ECS messages.

Here are the diagnostic procedures for those codes:
