WHILE TRAVELING AT 45 MPH, AND WITH NO WARNING (WEIRD SHIFTING, ETC) THE TRANSMISSION COMPLETELY FAILED. AFTER BEING LIED TO BY THE DEALERSHIP AND GM, I DID MY OWN RESEARCH AND FOUND THAT THIS IS A COMMON PROBLEM WITH THIS MODEL YEAR, SO MUCH SO THAT GM HAS CREATED A SPECIAL PROGRAM TO FUND PART OF THE REPAIR IF THE VEHICLE IS OUT OF WARRANTY. (WAVE PLATE FAILURE IN THE TRANSMISSION). THIS VEHICLE SHOULD BE RECALLED WITH A MANDATORY REPLACEMENT OF THE WAVE PLATE. *TR

DEALER DID STATE THAT THERE WAS A LETTER OUT ABOUT THIS PROBLEM BUT THE CURRENT WAY OF SOLVING IT IS NOT WORKING. *TR
