While driving my car the Brake, EBD, ABS ESC light come on with a inoperative message. Note there was not rain and I am driving in a straight line at speed of 35 -40 mph. The dealer stated that the ESP Control Unit need to be replace. I agree to have replace but now I having doubt that this may not have been the problem. Because they stated that they would need to do a diagnostic test that take 4 hours however in 2 hours they come back with I need my ESP control unit replace, also that they recommend my rear flex disc, serpentine belt and drive belt be replace. Seriously!!
