Transmission shudder from torque converter

2011 gmc Acadia slt gear shift does not lock causing it to slip into neutral with slightest bump of shifter or sudden hard breaking Also passenger seat belt does not.lock at all when breaking and driver side seat belt never unlocks there are safty recalls on these issues for this model but.says mine has zero unfixed recall also defrosting and mirror defrost does not work properly causing me to have very bad visibility I had a close call when driving in Houston a week ago when I had to slam breaks due to a crazy driver who did not see me.and cut me off the lane my gear shifted into neutral causing me to not be able to accelerate after breaking to avoid the next speeding car fortunately I was lucky and was able to quickly shift back into drive and go there are electrical issues as well and there...

I was driving on the freeway then my car suddenly started slowing down. I tried changing lane so i can pull over on the side of the freeway but unfortunately i couldn't get to pull over before the car completely stopped on the freeway. I called AAA. They sent a tow truck which came to the freeway to tow my car. My husband came and took me to work. The car was towed to a GMC dealership. I went to the dealership after work. I was told my car has timing chain problem and if not fixed will damage the engine. I went online to read reviews of this car only to see it was a very common problem for this year and model of GMC which if i have ever read those reviews i would not have bought a GMC. This vehicle should be recalled for this issue.

Looses power while driving. Cannot jump the battery it needs to be recharged every time. Power steering stops working while driving( low rpm and when stopped) dangerous for merging or lane changes. Engine shudders when trying to accelerate. TCM/ ECM replaced 2020. Problem still persists. Whining noise upon start of the vehicle. Auto start will not work. traction control light, check engine airbag and

While driving down the road, transmission will shudder and have difficulty maintaining constant speed. This is especially dangerous while merging on to the highway. It is searching for the gear to be in while rpms are fluctuating.

On July 27 at 400 pm I arrived home and my daughter went to take out the trash and I heard her scream daddy the car is on fire. I rushed outside and flames were 6 ft tall I called 911. After putting the fire out he stated th car was running doors locked so they couldn’t open the hood

Accordingly, the said vehicle first manifested a dangerous defect issue on July 14, 2021, while traveling out of town. A significant and abrupt reduction of power completely disabled the vehicle while parking in a parking space .Despite several attempts, the vehicle still fail to start. Only to notice the engine light illuminating and flashing repeatedly. At the same time the dashboard indicated a faulty reading of fuel and oil. This is a very serious and frightened situation because I received absolutely no warning before the vehicle shut down. Without reason of doubt, I do believe it is unsafe, extremely dangerous and is potentially a hazardous situation that should be investigated. Fortunately, I was in a parking lot went the problem occurred. Whereas, if the vehicle engine stopped abruptly in the mist of traffic it could have resulted with a different outcome. On July 16th the vehicle was towed to a...

I WAS TRAVELING TO DAYTONA FL FROM OHIO FOR VACATION. THE TRANSMISSION STARTED SLIPPING AND AS I GOT OFF THE EXIT FOR DAYTONA THE TRANSMISSION WENT OUT I BARELY MADE IT TO MY RENTAL. I HAD NO EXTRA MONEY AND CAN NOT RENT A CAR BECAUSE I HAVE NO MAJOR CREDUT CARD. SO I HAD TO TAKE OUT A LOAN FOR 3200.00 FOR A1 TRANSMISSION SHOP TO REBUILD THE TRANSMISSION.

WHEN I DRIVE THE VEHICLE FOR 2 HOURS OR MORE THE "TRANSMISSION HOT IDLE ENGINE" COME ON THE DASH AND I HAVE TO SLOW DOWN OR PARK THE VEHICLE FOR IT TO COOL OFF. I CAN NOT DRIVE AT 75 MPH OR 80 MPH WHEN ON THE HIGHWAY WITHOUT IT COMING ON.

TL* THE CONTACT OWNS A 2011 GMC ACADIA. WHILE ATTEMPTING TO TURN THE VEHICLE OFF, THE GEAR SHIFTER WOULD NOT SHIFT INTO THE PARK POSITION. AS A RESULT, THE IGNITION KEY COULD NOT BE REMOVED FROM THE IGNITION, CAUSING THE ENGINE TO KEEP RUNNING. THE FAILURE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE.

TRANSMISSION FLARES OUT (GOES INTO NEUTRAL) BETWEEN GEARS WHEN MERGING INTO HIGHWAY TRAFFIC AT SPEEDS OF AROUND 45-60 MPH. MOST OFTEN OCCURS WHEN INITIALLY ACCELERATING TO MERGE INTO FASTER TRAFFIC AND THEN HAVING TO TAKE MY FOOT OFF THE GAS FOR A SECOND OR TWO TO ALLOW FASTER CARS TO GO BY, AND THEN TRYING TO ACCELERATE AGAIN. THE TRANSMISSION IS IN NEUTRAL AND IT SEEMS IT IS CAUGHT BETWEEN GEARS (4TH & 5TH GEARS I BELIEVE) WHEN I TRY TO ACCELERATE AGAIN. ENGINE REVS TO 5000 TO 6000 RPM RANGE BECAUSE IT IS NOT IN GEAR. HAVE TO TAKE FOOT OFF OF THE GAS AND WAIT A COUPLE SECONDS FOR TRANSMISSION TO GET INTO GEAR SO I CAN CONTINUE DRIVING. IN THE MEANTIME FASTER CARS ARE APPROACHING AS I'M IN THE MIDDLE OF MERGING INTO HIGHWAY TRAFFIC. NOT BEING ABLE TO ACCELERATE WHEN MERGING INTO HIGHWAY TRAFFIC CREATES A...

I WAS DRIVING MY 2011 GMC ACADIA AND ALL OF A SUDDEN THE CAR STARTED TO DECELERATE. I PULLED OVER AND TURN THE CAR OFF AND THEN THE CAR WOULD NOT START AGAIN. I HAD IT TOWED TO THE DEALERSHIP. THE DEALERSHIP IS SAYING THERE IS AN ISSUE WITH THE TIMING CHAIN. THE DEALERSHIP SAID THAT THE TIMING CHAIN FAILED. UPON DOING RESEARCH, I SEE THAT THIS IS A COMMON ISSUE WITH GMC MODELS, ESPECIALLY THE ACADIA MODEL. THE DEALERSHIP IS SAYING THAT THE REPAIR IS GOING TO COST ME $7500. GIVEN THAT THIS IS WELL-KNOWN ISSUE WITH THE ACADIA MODEL, I FEEL THAT THIS ISSUE SHOULD BE RECALLED FOR THE SAFETY OF CONSUMERS.

I WAS COMPLAINING ABOUT THE PERFORMANCE OF THIS VEHICLE TO THE DEALER FOR THE PAST THREE YEARS. NOW THAT THE WARRANTY IS EXPIRED, I HAD TO CHANGE THE DRIVESHAFT, FELL OUT WHILE TRANSPORTING PASSENGERS; TRANSFER CASE, THE TRANSITION FROM DRIVE, THE AUTOMATIC SHIFT WOULD JERK; A PASSENGER I HAD IN THE CAR TOLD ME ONE DAY I WOULD NOT MAKE IT UP A HILL. ONE WEEK LATER IT HAPPENED. TRANSMISSION, THE VEHICLE WOULDN'T MOVE EVEN WHEN GAS WAS APPLIED; 6 COILS AND PLUGS, THE BAD SMELL OF SOMETHING BURNING WAS SCARY. I HAD TO PULL OFF THE ROAD BECAUSE THE REDUCE POWER LIGHT COME ON. YESTERDAY, 12/26/16, I WENT THROUGH THIS AGAIN!!! THERE IS A RUBBING SOUND IN ONE OF MY WHEELS, DON'T KNOW WHAT THAT IS YET. I ALSO CHANGED THE AXELS AND ABOUT TO CHANGE THE TIE RODS FOR A CLUNKING NOISE WHILE MAKING TURNS ON UNEVEN SURFACES....

MY VEHICLE HAS 136,000 MILES AND THE TIMING CHAIN IS OUT, I HAVE HAD TO HAVE THE FRONT PASSENGER AXLE REPAIRED, THERE IS AN OIL LEAK. I HAD THE VEHICLE CHECKED WHILE UNDER WARRANTY BECAUSE THE CHECK ENGINE LIGHT WOULD COME ON, THE SERVICE DEPARTMENT SAID IT WAS BECAUSE THE GAS CAP WASN'T TIGHTENED. NOW I HAVE NO WARRANTY AND THE TIMING CHAIN NEEDS REPLACED. THE FIRST DAY I DROVE MY VEHICLE THE BRAKE SYSTEM FAILED, IT WAS BRAND NEW. IT HAD HAD SEVERAL RECALLS.

"TAMARA RECALL". I RECEIVED SEVERAL NOTICES. INITIALLY AUTO DEALERSHIP DENIED RECALL EXISTED. NOW CLAIMS IT DOESN'T APPLY TO MY CAR. ORIGINAL OWNER AND LIVE IN SOUTH FLORIDA.

VEHICLE CAME OUT OF PARK SITTING IN DRIVEWAY WHILE BEING CLEANED OUT. THE KEY WAS NOT IN THE IGNITION; HOWEVER THE GEAR SHIFT WAS SHIFTED INTO PARK AS SOMEONE REACHED OVER ACROSS THE SEAT. PASSENGER SIDE DOORS WERE OPEN AND AS THE VEHICLE ROLLED , THE DOORS HIT MY POUCH CAUSING DAMAGE TO THE FRONT AND REAR PASSENGER DOORS. MY CHILDREN HAD TO JUMP OUT OF THE WAY TO AVOID BEING RAN OVER. THERE IS A SERIOUS DEFECT ON 2011 ACADIA AND THE RESULTS COULD HAVE BEEN DEADLY. I NEED FOR GMC TO FIX THIS PROBLEM. THE GEAR SHIFTER IS NOT SUPPOSE TO MOVE WITHOUT THE KEY IN THE IGNITION AND TURNED TO THE ON POSITION PLUS THE BRAKE MUST BE PUSH TO ACTIVE. SO GMC WHAT HAPPEN? I COULD BE BURYING ONE OF MY CHILDREN.

THE PARK ASSIST OFF , THE TRACTION CONTROL OFF, THE SERVICE STABILITRAK? AND THE ?CHECK ENGINE? LIGHTS ALL COME ON.

I PULLED OVER AND CALLED A TOW TRUCK AND HAD IT TOWED TO SHOP.THEY REPLACED ACCELERATOR PEDAL ASSEMBLY. COST ME $259.84. *TR

OVER THE PAST MONTH AND A HALF I HAVE BEEN NOTICING THAT WHEN I ATTEMPT TO PUSH THE GAS TO MAKE MY CAR GO FASTER THAT IT DOESN'T ACCELERATE. IT IS USUALLY WHEN MY VEHICLE IS ALREADY IN MOTION AND I ATTEMPT TO GO FASTER. I CAN HEAR IT MAKING A NOISE LIKE IT'S TRYING TO GO FASTER BUT THERE IS DEFINITELY A DELAY BEFORE THE VEHICLE ACTUALLY STARTS TO GO FASTER. USUALLY I AM ON A NORMAL STREETS GOING ANYWHERE FROM 35-55 MPH (DEPENDING ON THE STREET AND POST SPEED LIMIT), SO IT'S NOT ALWAYS A HUGE DEAL WHEN IT HAPPENS. I DO A LOT OF HIGHWAY DRIVING AND THIS IS WHERE MY CONCERN COMES INTO PLAY. A FEW WEEKS AGO I WAS MERGING ONTO 696. THERE WAS MORE THEN ENOUGH ROOM IN THE FIRST LANE FOR ME TO SAFELY MERGE INTO TRAFFIC, HOWEVER, WHEN ATTEMPTING TO ACCELERATE MY...
