2018 GMC Sierra 1500

WHEN TRUCK IS IN MOTION SHIFTING FROM REVERSE TO FIRST/SECOND GEAR IT JUMPS FORWARD INTO GEAR. THERE IS A HESITATION SHIFTING INTO GEAR. IT IS A VERY WELL KNOWN PROBLEM WITH THE 8 SPEED TRANSMISSION. I HAVE BEEN IN CONTACT WITH THE DEALER BUT 3 DIFFERENT TIMES. THE KNOW THE PROBLEM AS DOES GMC. THEY ACTUALLY CAN FIX THE PROBLEM. BUT WILL NOT DO ANYTHING UNTIL GMC SENDS OUT A TECHNICAL BULLETIN. THERE HAS BEEN AN UNBELIEVABLE AMOUNT OF COMPLAINTS. I UNDERSTAND GMC IS HESITANT BECAUSE THEY MAY HAVE TO REPLACE TRANSMISSION AND OR TORQUE CONVERTER WHICH WOULD NATURALLY COST A LOT OF MONEY. BUT ALSO I UNDERSTAND CHANGING TO A DIFFERENT TRANSMISSION FLUID WILL HELP. BUT DEALER WILL NOT DO IT. THIS HAS BEEN GOING ON SINCE THE DAY I BOUGHT IT BRAND NEW AND I ONLY HAVE 5700 MILES ON IT. I HAVE NOT HAD ACCIDENT BECAUSE OF THIS. BUT CONCERNS ME WITH THE HESITATION AND JUMPING IN TO GEAR. ALSO IT DOES NOT DO IT EVERY SINGLE TIME. DEPENDS ON YOUR TAKE OFF SPEED. *TR

I BOUGHT THIS VEHICLE NEW FROM DAY ONE I NOTICED THE TRUCK WAS JERKING BETWEEN 2ND GEAR AND THIRD. ONLY WHEN COLD I FIGURED IT WAS NORMAL. I HAVE 11,000 MILES NOW AND THE JERKING IS WORSE AND DOES IT WHEN I HOLD A SPEED BETWEEN 45MPH AND 50MPH ALSO. WHEN I AM COMING TO A STOP IT HIT HARD INTO 1ST GEAR AND WHEN I TAKE OFF IT HITS HARD INTO 2ND GEAR. *TR

A/C STOPS WORKING 2.) MECHANIC DOES VACUUM TEST AND REPLACES REFRIGERANT ($200) FREON 3.) A/C IS BLOWING HOT AIR AGAIN AFTER 3 DAYS; REFRIGERANT COMPLETELY GONE 4.) MECHANIC RUNS DYE THROUGH LINES TO FIND THE LEAK, REPLACES REFRIGERANT AGAIN AND STATES THE PROBLEM IS COMPRESSOR FAILURE ($200) AGAIN 5.) THE OVERALL FIX WOULD BE TO REPLACE THE COMPRESSOR ($1,000) BUT THERE ARE NO COMPRESSORS TO BE FOUND, THE PART IS ON NATIONAL BACKORDER BECAUSE OF THE WIDESPREAD PROBLEM." LEFT SIDE OF WHEEL MAKING ALOUD NOISE WHEN BACKUP , IT IS A KNOW PROBLEM WITH THE STEERING RACK TANSMISSION DOWNSHIFT FROM 30-15 MAKE A PUSH EFFECT AND COUCHING NOISE

I HAVE A 2018 GMC SIERRA DENALI, WHEN THE VEHICLE IS COLD, USUALLY FIRST THING IN THE MORNING, THE TRUCK STARTS OUT IN FIRST GEAR AND THEN FEELS LIKE IT LACKS POWER OR TRANSMISSION IS SLIPPING AND THEN BANGS INTO 2ND GEAR.THE MORE I DROVE THE TRUCK THE WORSE IT GOT. WHILE DRIVING DOWN THE ROAD THERE IS A VIBRATION WITHIN THE TRUCK. THE FASTER YOU GO THE MORE OF A VIBRATION YOU FEEL. DURING THE VIBRATION THE STEERING WHEEL IS NOT SHAKING AND WHEN YOU LET GO OF THE WHEEL THE TRUCK STAYS STRAIGHT, SO IT'S NOT THE FRONT END. TOOK THE TRUCK TO THE DEALERSHIP WHERE IT WAS PURCHASED, PELLEGRINO GMC, WHICH IS A 30 MINUTE DRIVE AND THEY COULDN'T DUPLICATE THE PROBLEMS. THE SERVICE ADVISOR WAS ADVISED PRIOR TO MY APPOINTMENT, THAT THE BANGING INTO GEAR ONLY HAPPENS WHEN ITS IS COLD. HE ADVISED ME THAT WHAT I WAS FEELING WAS A NORMAL SHIFT FOR MY TRUCK. I ADVISED HIM ABOUT THE SERVICE BULLETINS AND HE STATED THAT IT DIDN'T PERTAIN TO MY TRUCK.THE MECHANIC TEST DROVE MY VEHICLE FOR 13 MILES AND DIDN'T FEEL THE VIBRATION. HE CHECKED THE ENGINE CODES AND FOUND NONE. I HAVE HAD THE TRUCK A LITTLE OVER A YEAR AND IT HAS 6000 MILES ON THE ODOMETER.

I OWN A GMC SIERRA WHICH IS 14 MONTHS OLD, PURCHASED IN DUBAI UAE FROM ALGHANDI AUTO. THE LAST SERVICE FOR 40000 KMS WAS DONE ON AUGUST 8TH, 2019 AND NO PROBLEM WAS HIGHLIGHTED EXCEPT THE BATTERY THAT WAS SUBSEQUENTLY CHANGED. ON FRIDAY EARLY MORNING (SEP 27, 2019), WE HAVE ESCAPED A MAJOR ACCIDENT ON SHEIKH ZAYED ROAD ON ACCOUNT OF THE FRONT WHEEL AXLE THAT JUST BROKE/CAME APART WHILE DRIVING, CAUSING THE FRONT RIGHT WHEEL TO DETACH FROM THE VEHICLE, SUBSEQUENTLY SKIDDING TO THE RIGHT CAUSING MAJOR DAMAGE TO THE SUSPENSION AND MANY OTHER PARTS IN THE VEHICLE. THIS COULD HAVE CAUSED EVEN DEATH OF MY SON WHO WAS DRIVING THE VEHICLE. I WOULD APPRECIATE AN IMMEDIATE CALL FROM YOUR OFFICE TO RESOLVE THIS AS I AM NO LONGER INTERESTED IN DRIVING THIS CAR THAT CAN COST ME & MY FAMILY OUR LIVES. THIS NEEDS TO BE DONE IMMEDIATELY AS I WOULD OTHERWISE BE IN THE PROCESS OF SEEKING LEGAL ADVICE AGAINST GMC. *JB
