NHTSA Complaint #10946389 — 2010 GMC TERRAIN

I AM ADDING ON ADDITIONAL INFORMATION TO MY PREVIOUS COMPLAINT #10938600. GMC SCA #14159, 14232, 15810, 12313, AND MY TRANSMISSION FAILURE ALL SEEM TO FALL VICTIM TO EXCESSIVE HEAT. I WAS PULLING INTO TRAFFIC WHEN THE TRANSMISSION FAILED. MY TERRAIN HAS FALLEN VICTIM TO THREE POSSIBLY FOUR OF THE FIVE CALAMITIES. THERE IS NO REASON TO BELIEVE ALL FIVE WILL NOT FAIL UNDER THE SAME DRIVING CONDITIONS. SOMEHOW NOT ONCE DID WARNING LIGHTS COME ON FOR MULTIPLE ENGINE OIL OCCURRENCES, NOR FOR MY TRANSMISSION FAILURE. I WAS AN HVAC CHILLER TECHNICIAN FOR 28 YEARS. WHEN I HEAR ECM REFERENCED, AS IN SCA#12312, I HAVE TO ASK WHICH VALUES WERE CHANGED AND WHY. THERMISTORS AND PRESSURE SWITCHES DESIGNED TO PROTECT VITAL ENGINE COMPARTMENT COMPONENTS RUN THROUGH THE ECM YET NO WARNING. MY TRANSMISSION FAILED ON DECEMBER 4, 2016, THE CATALYTIC CONVERTER MAY BE BAD, THE STEERING GEAR IS SUSPECT, AND THE ENGINE WARNING LIGHTS HAVE NOT DONE WHAT THEY ARE SUPPOSED TO DO. THE UNNECESSARILY LONG DELAY IN ADDRESSING THE OIL CONSUMPTION ISSUE OUTLINED IN SCA#14159 PROBABLY COMPROMISED MY ENGINE IN OTHER WAYS. SCA#12313 RESULTED FROM GM DELAYING THE REPAIR OF SCA#14159 FOR SO LONG. WHAT, WHY, AND HOW. WE KNOW WHAT IS FAILING. SIMPLY REPLACING THE PART IN KIND OR SIMILAR IS NOT ADDRESSING WHY. HOW DO WE KEEP IT FROM HAPPENING AGAIN IS DEFINITELY NOT BEING ADDRESSED. SAFETY AS WELL AS QUALITY ISSUES ARE AT HAND HERE. GM HAS IGNORED MY REQUESTS FOR ALL INFORMATION REGARDING SCA#14159, 14232, 15810, 12313, AND 12312, AS WELL AS THE TRANSMISSION. WHY THEY ARE FAILING IS EXCESSIVE HEAT. THAT IS JUST MY GUESS. THEY KNOW WHAT IT IS. I CAN NOT AFFORD A COSTLY TRANSMISSION BILL THAT ONLY FINDS ME BACK IN AN UNRELIABLE VEHICLE WITH SOME SERIOUS SAFETY ISSUES. *TR
