Over the past month, at times the brake pedal will feel weird in that there is a springy sensation/feedback upon applying brakes; this is momentary and goes away. My PA Soft program has started giving me "Hardware is not Ready" error and I have not been able to retrieve codes as of yet. At least three times, the brake, traction control and ABS lamps have come on with the funny brake pedal feedback. After one or two driving cycles, the lamps go off and everything appears normal. I need to take care of this and will pull codes once I take care of the scanner issues. Based on this qualitative description, I am looking for some leads. TIA.
