ENGINE
WHILE DRIVING WITH THE ROADS IN A WET CONDITION, FOR VARIOUS LENGTHS OF TIME, AND IN DIFFERENT MANEUVERS, THE SERVICE ENGINE LIGHT WILL START FLASHING AND THE VEHICLE WILL BEGIN TO LOSE POWER. AFTER A FEW MINUTES, THE SERVICE ENGINE LIGHT WILL GO SOLID AND THE TRACTION CONTROL LIGHT WILL ILLUMINATE. THE VEHICLE LOSES MORE POWER. ON BRAKING, JUST BEFORE THE VEHICLE COMES TO A COMPLETE STOP, THERE IS A CLUNK IN THE TRANSMISSION AND THE VEHICLE LURCHES. THIS HAS OCCURRED 6 TIMES IN THE LAST 14 MONTHS. UPON INVESTIGATION, TROUBLE CODE P0308 SHOWS IN THE OBD TOOL. THE ISSUE COULD NOT BE REPRODUCE BY THE DEALERSHIP SO THERE HAS NOT BEEN ANY RESOLUTION, JUST THOUGHTS.

I HAVE TAKEN MY TRUCK TO TEMECULA VALLEY BUICK GMC ON 3 SEPARATE OCCASIONS AFTER NOTICING MY TRANSMISSION SHIFTS HARD. I HAVE EXPERIENCE CLUNKING SHIFTS BOTH IN THE UP SHIFT AND DOWN SHIFT, TYPICALLY AT LOWER SPEEDS. THERE ARE TIMES WHEN THE TRANSMISSION SHIFTS GEARS IT PROPELS THE VEHICLE FORWARD IN A JERKING FASHION, VERY SIMILAR TO A REAR END FENDER BENDER. THE LAST TIME I TOOK MY VEHICLE TO THE DEALERSHIP, I WAS TOLD THAT THE VEHICLE IS SHIFTING AT NORMAL SPECS AND IF IT KEEPS ACTING UP, TO BRING IT BACK WHEN IT IS MORE CONSISTENT. THE VEHICLE'S WARRANTY RUNS OUT IN A FEW MONTHS.

POWER TRAIN, UNKNOWN OR OTHER
AFTER COLD STARTS WHEN ACCELERATING THE TRANSMISSION SLIPS FROM 1ST TO 2ND AND THROWS YOUR BODY FORWARD. AFTER THAT FIRST GEAR CHANGE IT DOESN'T DO IT AGAIN UNTIL ANOTHER COLD START. AROUND 34000 MILES I AM GETTING A RUMBLING VIBRATION THROUGH THE DASH AND STEERING WHEEL WHEN HOLDING SPEED BETWEEN 35-75 MPH. THE RPM GUAGE WILL JUMP SLIGHTLY AND IT WILL FEEL LIKE GOING OVER RUMBLE STRIPS. ACCELERATION IS VERY WEAK AT TIMES. SOMETIMES ITS OK. THERE HAS TO BE SOMETHING DONE WITH THESE TORQUE CONVERTERS AND TRANSMISSIONS BY GM. UNACCEPTABLE FOR A 40-50K DOLLAR TRUCK!

I HAVE HAD MY GMC SIERRA 1500 FOR ALMOST 3 YEARS. I HAVE A LITTLE UNDER 59,000 MILES ON THE TRUCK. A FEW THOUSAND MILES AGO A TECH AT THE GM DEALER LET ME KNOW THAT THEY HAD TO ADD SOME COOLANT AND IT WAS SOMETHING I SHOULD KEEP AN EYE ON. I BROUGHT THE VEHICLE BACK TO HAVE THEM LOOK INTO IT. THEY LET ME KNOW THAT THE RADIATOR HAS A SMALL LEAK. IT IS NOT BIG ENOUGH TO HAVE FLUID HIT THE GROUND IN MY GARAGE BUT IT IS LOOSING FLUID. I LOOKED ONLINE AND SAW THAT THIS IS A COMMON ISSUE. I WAS TOLD THAT IT WAS NOT COVERED UNDER WARRANTY AND IT WOULD COST A GOOD AMOUNT TO FIX. I HAVE HAD THIS VEHICLE FOR UNDER 3 YEARS AND HAVE HAD 5 ISSUES WITHOUT ANY OF THEM BEING COVERED BY WARRANTY. THIS VEHICLE SEEMS TO BE A LEMON.

SERVICE BRAKES, ELECTRONIC STABILITY CONTROL (ESC), STEERING
ON THE MORNING OF OCT 26, 2020 @ 845AM... I WAS HEADING SOUTH ON 287 IN MANSFIELD TX. IT WAS RAINING HARD SO I WAS ONLY GOING 60 MPH. THE CAR IN FRONT OF ME WAS GOING 55 OR SO. WHEN THE RAIN AND WIND PICKED UP, THE CAR IN FRONT OF ME ABRUPTLY HIT ITS BRAKES. THAT'S WHEN MY TRUCK BRAKES LOCKED AND I BEGAN SLIDING OR BEING PULLED TO THE RIGHT. I WAS IN THE LEFT LANE ON THE 2 LANE HIGHWAY. HAD IT NOT BEEN FOR GOD AND ME, NOT PANICKING... I WOULD HAVE CRASHED! MY TRUCK FISH TAILED TWICE WHILE I WAS TRYING TO APPLY THE BRAKES BUT... I COULDN'T STOP. I ALMOST PUT THE TRUCK GEAR IN NEUTRAL BUT IT WAS RAINING SO SOMEHOW THE TRUCK MANAGED TO SLOW DOWN GOING UP A SMALL HILL, GIVING ME CONTROL BACK. THERE WERE 2 OTHER CARS THAT SEEN THIS. I WAS A NERVOUS WRECK! I IMMEDIATELY GOT OFF THE HIGHWAY AND WENT TO THE FIRST GAS STATION I SAW AND THANKED GOD NOTHING HAPPENED. THE PROBLEM I HAVE IS, WHAT IF MY FAMILY WERE IN THE VEHICLE? HOW IS IT THAT GM IS ALLOWED TO SELL THESE VEHICLES? ALSO, I SEARCHED ALMOST EVERY WEBSITE AND INCLUDED MY VIN... BUT EVERY REPLY SAYS MY TRUCK IS OK (UNTIL TODAY). I HAVEN'T HAD THIS TRUCK FOR A YEAR YET. BUT I'M READY TO TRADE IT IN. I DON'T FEEL SAFE AT ALL. I ALMOST WANT TO GET MY TRUCK TOWED HOME. WHY PUT PEOPLE LIVES IN JEOPARDY?

SERVICE BRAKES, ELECTRONIC STABILITY CONTROL (ESC), STEERING
I NEARLY DIED WHEN MY BRAKES FAILED ON MY 2018 GMC DENALI THIS MORNING. I WAS ONLY GOING 60 MPH WHEN ANOTHER DRIVER CUT IN FRONT OF ME, AND HIT THEIR BRAKES BUT WHEN I TRIED TO STOP, I COULD NOT! I THEN BEGAN SWERVING FROM LANE TO LANE BECAUSE IT WAS RAINING. THANK GOD I DIDN'T DIE AND THAT THE PERSON ON THE RIGHT SLOWED DOWN AND MOVED OUT THE WAY. THE TRUCK SEEMED TO BE PULLING ME TO THE RIGHT. WHY I HAVE NO IDEA. BUT WHY IS GM PUTTING PEOPLE LIVES AT RISK LIKE THIS? WHY ARE WE HAVING TO SUFFER OR PUT OUR FAMILIES IN JEOPARDY. THIS MAKES NO SENSE. MY CHEST STARTED HURTING REALLY BAD AFTERWARDS, BECAUSE I WAS SO SCARED. I WAS ON A 2 LANE HIGHWAY GOING STRAIGHT BUT EVEN THAT DOESN'T CAUSE A VEHICLE NOT TO RESPOND LIKE IT DID.

HESITATION WHEN ENGINE IS COLD SHIFTING FROM REVERSE TO DRIVE. SOME SHIFT IS SO HARD THAT IT FEELS LIKE BEING HIT FROM BEHIND. TOOK TRUCK TO DEALERSHIP TO CORRECT THE PROBLEM. THEY PERFORMED THE TSB 18-NA-355. THIS DID NOT CORRECT THE PROBLEM. DEALERSHIP ADVISED THERE WAS NOTHING ELSE THEY COULD DO ABOUT THIS ISSUE.

SERVICE BRAKES, ELECTRICAL SYSTEM, POWER TRAIN
THE FIRST THING THAT HAPPENED WAS THAT ALL OF THE ELECTRICAL SYSTEMS ON MY TRUCK WENT OUT AND MY TRUCK WOULD NOT START. IT FINALLY STARTED BUT IT WOULD NOT MOVE FINALLY IT WOULD MOVE BUT VERY SLOWLY THIS HAPPENED ON 11/20/2019 I HAVE DOCUMENTATION THROUGH ONSTAR FOR THIS INCIDENT. MY BRAKES STARTED SLIPPING ON 07/01/2020 AND STILL DO NOT WORK PROPERLY. MY TRANSMISSION HAS NEVER SHIFTED CORRECTLY. WHEN I ACCELERATE OR WHEN I SLOW DOWN THERE IS A SHUDDER AND A JERKING SOUND. AFTER SITTING FOR A WHILE WHEN MY TRUCK IS PUT IN REVERSE IT HESITATES AND THEN SEEMS TO JUMP INTO GEAR.

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.

I RECEIVED A RECALL NOTICE FOR A BRAKE PROBLEM ON MY TRUCK. THE RECALL GAVE A LOCATION TO TAKE MY TRUCK FOR SERVICE. WHEN I CONTACTED THAT DEALERSHIP THEY SAID IT WAS A CANADIAN TRUCK AND THEY COULDN'T PERFORM THE RECALL REPAIR. SO I CALLED THE GM HOT LINE THEY SAID I HAD TO TAKE IT TO CANADA FOR THE REPAIR AND THAT WAS THE ONLY OPTION.
