MY TWO CHILDREN AND I WERE TRAVELING ON A HIGHLY ELEVATED RAMP BETWEEN MAJOR HIGHWAYS IN SAN ANTONIO (281 AND 1604) WHEN MY CAR NO LONGER WOULD MOVE INTO A HIGHER GEAR AND SUDDENLY STALLED AT ITS CURRENT SPEED. THE ENGINE ROARED, BUT THE CAR WOULD NOT GO FASTER. THE TRAFFIC BEHIND ME ALMOST HIT ME, AS I UNEXPECTEDLY WAS NOT INCREASING SPEED AS ONE WOULD TYPICALLY DO ENTERING A HIGHWAY. IT WAS EXTREMELY FRIGHTENING TO ALL THREE OF US (ESPECIALLY MY 9 YEAR OLD) AND REQUIRED OUR EXITING THE HIGHWAY IMMEDIATELY. THE PROBLEM CONTINUED, AND WE IMMEDIATELY TOOK THE CAR INTO THE DEALERSHIP SERVICE CENTER. THE TECHNICIAN WAS ABLE TO DETERMINE THE PROBLEM QUICKLY, BECAUSE IT HAS BEEN A FREQUENT REPAIR. THE "WAVE PLATE" FAILURE LED TO THE FAILED TRANSMISSION WITH ADDITIONAL ENGINE PROBLEMS. THE BILL EXCEEDS $6000. BOTH THE NEAR ACCIDENT AND COST HAVE BEEN HIGHLY STRESSFUL. WE WANT GM TO ADDRESS THIS "WAVE PLATE /TRANSMISSION" ISSUE BEFORE MORE PEOPLE ALMOST GET HURT. THE FORUMS FOR GM VEHICLES CONTAINING THIS PART HAVE DOZENS OF COMPLAINTS ALREADY. *TR
