At approximately 700 miles, my check engine light came on and the car produced an error message that said "Idle Creep Temporarily Disabled". Soon after that the car would lurch, buck on acceleration, and would only drive in even numbered gears. I felt the car was extremely dangerous and unpredictable to drive in this state since the car was unpredictably bucking and lurching forward and not shifting smoothly as usual. The dealer ran an OBDII poll and found five codes relating to transmission issues. GM has admitted to me that my vehicle is one of several that have "Assembly Debris" in the TREMEC supplied DCT. This "Assembly Debris" made the transmission filter completely black in appearance at 750 miles in addition to triggering the check engine light and dangerous driving behavior.
