POWER TRAIN
2014-2015 GMC SIERRAS WERE PRODUCED WITH A KNOWN FAULTY A/C CONDENSER WITH A BAD WELD THAT CAUSES AN A/C SYSTEM LEAK REQUIRING REPLACEMENT. THERE HAS BEEN AN OVERWHELMING FAILURE OF THE PRODUCT ACROSS THE COUNTRY, SO BAD SO THAT IT EVEN MADE THE NEWS. GM BECAME AWARE OF THIS ISSUE AND SENT NEW (PROPERLY PRODUCED) CONDENSERS TO THEIR PRODUCTION LINES FIRST, LEAVING HUNDREDS OF GMC OWNERS WITHOUT A/C OVER THE SUMMER. THEY PUT OUT A "SPECIAL RECALL" ON A VERY SMALL NUMBER OF VINS SAYING IT "MAY" HAPPEN IN OTHER VINS. THERE IS AN OVERWHELMING VOLUME OF COMPLAINTS ONLINE (INCLUDING MYSELF) WHERE GM IS ACKNOWLEDGING THIS ISSUE BUT REFUSING TO COVER THE REPLACEMENT COST OF THEIR FAULTY PART FOR HUNDREDS OF OWNERS HAVING THIS ISSUE. THIS REPAIR COST ME A LITTLE OVER $1300. IN THE SAME SERVICE VISIT FOR MY AC CONDENSER IT WAS IDENTIFIED THAT MY RADIATOR WAS LEAKING. THIS WAS DUE TO A FAULTY THERMOSTAT CAUSING STRESS FRACTURES IN THE RADIATOR CAUSING COOLANT TO LEAK. THIS ISSUE HAS ALSO BEEN IDENTIFIED BY GM HOWEVER ONLY A SELECT FEW VIN'S RECEIVED WARRANTY RECALLS. MY TOTAL REPAIR COST TO FIX BOTH ISSUES WAS IN EXCESS OF $4000. BOTH PROBLEMS ARE KNOWN TO GM YET THEY HAVE NOT REMEDIED THE ISSUE FOR EVERYONE.

SERVICE BRAKES
THE BRAKES FAILED AS MY SON APPROACHED AN INTERSECTION. SUBSEQUENTLY, HE STRUCK ANOTHER VEHICLE BROADSIDE. EXTENSIVE DAMAGE WAS SUSTAINED TO BOTH VEHICLES. THE DRIVER REPORTED THAT HE PRESSED THE BRAKE PEDAL, BUT THE TRUCK WOULD NOT STOP. AFTER I INVESTIGATED FURTHER FOR AN EXPLANANTION,I DISCOVERED THAT THERE WAS A RECALL ON HIS BRAKE SYSTEM THAT MIGHT EXPLAIN BRAKE FAILURE. THE CRASH OCCURRED ON A CITY STREET.

AFTERWARD, THE VEHICLE WOULD STOP, BUT THE BRAKES WERE SQUISHY AND VERY EASILY OVER APPLIED. SERVICE BRAKE CONTROL MESSAGE IS NOW ON THE DASH. TRUCK HAS 42000 MILES.

HARD SHIFTING THAT STARTED AROUND 40000 MILES AND HAS PROGRESSIVELY GOTTEN WORSE. THE SAME THING HAPPENED TO MY 2017 CHEVROLET SILVERADO 1500 AND AT 90000 MILES THAT VEHICLE'S #3 SENSOR IN THE TRANSMISSION FAILED. IT APPEARS THIS VEHICLE IS ON THE SAME PATH. THE TRANSMISSIONS IN THESE VEHICLES ARE TRASH. IT HAPPENS IN LOWER GEARS.

MY WIFE WAS TRAVELING BACK FROM STORE IN A 08 GMC SIERRRA. AS SHE APPROACHED RED LIGHT BOTH DRIVER AND PASSENGER SIDE AIR BAGS DEPLOYED! NO ONE ELSE IN THE VEHICLE. PAVED ROAD AND TRAVELING ABOUT 15-20 MPH. THE AIRBAG ON THE PASSENGER SIDE DESTROYED THE WINDSHIELD ON THE PASSENGER SIDE. LOOKED LIKE SOMEONE TRIED TO THROW A BRICK THRU IT.
