AFTER FILLING UP WITH GAS THE VEHICLE FAILED TO START. MY HUSBAND JUMPED THE CAR OFF AND ONCE STARTED THE CHECK ENGINE LIGHT CAME ON WITH AN ERROR CODE OF P062F. NOW, IT HAPPENS RANDOMLY BUT IS BECOMING MORE FREQUENTLY IN LAST WEEK' IT WILL FAIL TO START THEN THE CHECK ENGINE LIGHT WILL APPEAR WITH THE SAME ERROR CODE, WHILE DRIVING AT TIMES IT WILL BEGIN TO STALL UNTIL THE GAS PETAL IS ENGAGED AGAIN. PER THE GMC DEALERSHIP IT'S THE CHASSIS ELECTRONIC CONTROL MODULE HOWEVER MY VEHICLE YEAR MODEL DOESN'T FALL UNDER THE RECALL, BY ONE YEAR.

MY WINDOWS WILL ROLL DOWN ON THEIR OWN WHILE GOING DOWN THE ROAD. I CAN ONLY ROLL THE WINDOWS UP AND DOWN INTERMITTENTLY WHILE PARKED AND IN MOTION. WHILE DRIVING STABILITY CONTROL WILL TURN ITSELF OFF AND BLOW SOME SORT OF GAS THROUGH THE AIR CONDITIONING VENTS IN THE CAR, THEN IT WILL START SHUDDERING AND SLOWING DOWN THE CAR TO THE POINT I HAVE TO PULL OVER. AFTER THAT ISSUE STARTED, MY A/C WILL ONLY WORK INTERMITTENTLY AS WELL.

MY 2012 GMC ACADIA WAS RECALLED REGARDING THE LIFTGATE FALLING. I TOOK MY ACADIA IN TO BE SERVICED AS PART OF THIS RECALL IN 2017. NOW, IN 2019 MY LIFTGATE FALLS. WHILE MY ACADIA WAS IN "PARK" I PRESSED THE BUTTON TO OPEN THE POWER LIFTGATE, THE LIFTGATE CLOSED WHILE I WAS UNLOADING THE TRUNK. I WAS WEDGED BETWEEN THE BUMPER OF THE ACADIA AND THE LIFTGATE. I HAD TO PUSH AGAINST THE LIFTGATE (WHILE IT CONTINUED TO TRY AND CLOSE) IN ORDER TO DISLODGE MYSELF. AFTER GETTING THE LIFTGATE OPEN I LET GO AND IT FELL QUICKLY AND SLAMMED SHUT. HAD MY CHILDREN BEEN PRESENT AND WERE HELPING UNLOAD THIS COULD HAVE CAUSED SERIOUS INJURY AND EVEN DEATH. I AM EXTREMELY CONCERNED FOR THE SAFETY OF MY CHILDREN AND NO LONGER ALLOW THEM TO GO NEAR THE REAR OF THE "FAMILY" VEHICLE. I DID TAKE MY ACADIA IN TO BE SERVICED PER THE RECALL AND MY LIFTGATE FALLS. I WRITE THIS COMPLAINT TO WARN OTHER PARENTS THAT EVEN THOUGH YOU MAY HAVE HAD YOUR VEHICLE SERVICED AS PART OF THE LIFTGATE RECALL IT DOES NOT GUARANTEE THAT YOUR LIFTGATE WILL NOT FALL.

WHILE DRIVING AT HIGHWAY SPEEDS LAST WEEK MY 2012 AWD ACADIA HAVING A MAJOR MALFUNCTION. 1. WHILE DRIVING, DOOR LOCKS ENGAGE/DISENGAGE 2. TRANS APPEARS TO SLIP INTO NEUTRAL (HIGH REV/ NO POWER) 3. ON THE DASHBOARD DIGITAL READOUT THE TRANSMISSION "BLINKED" INTO P FROM D (WHILE DRIVING) 4. TRACTION CONTROL ENGAGES/DISENGAGES AND THE VEHICLE LURCHES FORWARD AND HARD STOPS 5. TRANS ENTERS SOME SORT OF LIMP HOME MODE WHERE IT ALLOWS ME TO DRIVE ONLY UP TO 60MPH, @4000 RPM (LIKE 3RD GEAR) THIS PROCESS REPEATED CONTINUALLY FOR OVER AN HOUR DRIVE TO THE DEALER, NORMAL OPERATION APPEARED TO OCCUR AT SPEEDS BELOW 45MPH, BUT ONLY TEMPORARILY AND THE ISSUE CONTINUED AGAIN AT THE LOWER SPEEDS. I CALL ONSTAR AND THEY PULL CODES FOR ME WHILE ENROUTE TO THE DEALER: ECM CODE =U0101 TCM CODE= NONE (FAILED TO PROBE MODULE) ABS CODE= U0101 ABS CODE= C0561 (ISSUE WITH TRACTION CONTROL SYSTEM)- "SERVICE WITHIN 7 DAYS" A QUICK SEARCH IN AUTOMOTIVE FORUMS REVEALS SEVERAL OTHER PEOPLE WITH ALMOST THE EXACT SAME ISSUE, WITH NO SPECIFIC SOLUTIONS.

ON MARCH 22, 2019, I WAS DRIVING HOME FROM WORK ON RTE. 130, AGAIN IN THE FAST LANE, I HEAR THAT FAMOUS BEEP AGAIN, BUT KNEW I DID NOT REQUIRE GAS. MY VEHICLE READ TO SERVICE STABLE TRACK ONCE AGAIN AND TRACTION CONTROL OFF. MY TRUCK DROPPED DOWN TO BASICALLY NO POWER IN THE FAST LANE ON A MAJOR HIGHWAY. THANK GOD I SAID MY PRAYERS THAT DAY, AND THREE CARS THAT ALMOST PLOWED INTO THE BACK OF MY TRUCK AND ANY ACCIDENTS WERE AVOIDED. I WAS ABLE TO PUT ON MY HAZARD LIGHTS, ONCE AGAIN, AND MAKE MY WAY OVER TO THE SHOULDER OF THE HIGHWAY AND WAS ABLE TO GET MY TRUCK INTO A SHOPPING CENTER PARKING LOT. I HAD THE GAS PEDAL ALL THE WAY DOWN TO THE FLOOR, BUT MY TRUCK WAS MOVING AT ABOUT 10 MILES PER HOUR'. NOWHERE!! I WAS SCARED BUT RELIEVED BECAUSE IT COULD HAVE BEEN WORSE. I COULD HAVE CAUSED A MAJOR ACCIDENT, OR EVEN BEEN HURT. I CONTACTED MY DEALERSHIP T&T COAST IN SEA GIRT, AND EXPRESSED TO THEM MY PROBLEM. I TOLD THEM I JUST HAD THIS STABLE TRACK/SENSOR REPLACED JUST A YEAR AGO, I SHOULD NOT BE FACING THE SAME ISSUE. THEY MADE FALSE PROMISES, PROMISED TO GET ME INTO A MORE RELIABLE VEHICLE, BUT IT DID NOT WORK OUT DUE TO MY CURRENT CREDIT ISSUES. I ASK IF THEY COULD NOT GET ME INTO A MORE RELIABLE TRUCK, COULD THEY AT LEAST FIX THE ISSUE THAT I THOUGHT WAS JUST REPAIRED BY THE SERVICE DEPARTMENT. THEY TOLD ME NO, IT WAS MY ISSUE BECAUSE OF THE HIGH MILEAGE ON THE CAR. I HAVE LEARNED THAT A STABLE TRACK/SENSOR OR TRACTION CONTROL IS SUPPOSED TO LAST THE LIFE SPAN OF YOUR VEHICLE. IT SHOULD NOT GO DUE TO WEAR AND TEAR OR HIGH MILEAGE. I ALSO DID ADDITIONAL INVESTIGATION ON MY END, AND LEARNED THAT GMC HAS BEEN HAVING THIS SAME ISSUE WITH MANY OTHER CUSTOMERS, ALONG WITH ELECTRICAL ISSUES.

THE ENGINE MISSES AND HAS SEVERE CARBON BUILDUP ON THE VALVES. THE INTAKE BOOT AND INTAKE MANIFOLD ARE COVERED IN OIL RESIDUE FROM THE BREATHER TUBE FOR THE MOTOR. THE TRANSMISSION STARTED HAVING ISSUES AT 100K. IT HESITATES, SHUTTERS, AND FAILS TO CHANGE GEARS WHILE DRIVING AT HIGHWAY SPEEDS. THE TRANSMISSIONS ARE A KNOWN ISSUE AND I DONT UNDERSTAND HOW THIS IS NOT A RECALL.

TOOK MY CAR INTO GARAGE BECAUSE ENGINE LIGHT CAME ON AND I ALMOST STALLED OUT MULTIPLE TIMES BEFORE I MADE IT TO THE GARAGE. MY CAR WAS TRAILING SMOKE. THE CODE SAID THE TIMING BELT WAS AFFECTED. HE SAID THAT USUALLY MEANS THE WHOLE ENGINE NEEDS REPLACED. MY CAR JUST TURNED 80,000 MILES. HE SAID CAR ENGINES LAST MUCH LONGER THAN THAT, IT SHOULD NOT HAVE ANYTHING WRONG WITH IT. HE TOLD ME THAT MANY GM MOTORS ARE RECALLED, THIS MODEL AND AGE SHOULD'VE BEEN RECALLED WITH AS MANY CUSTOMERS HE'S SEEN IN HIS SHOP WITH THE SAME PROBLEM. I BOUGHT MY CAR BRAND NEW IN 2012, I KNOW HOW IT WAS TAKEN CARE OF. THE ENGINE SHOULD NOT BE BREAKING DOWN JUST AS THE PAYMENTS CAME TO AN END. DO THE RIGHT THING AND RECALL THE ENGINES.

MY LOW BEAM HEAD LIGHTS KEEP BLOWING OVER THE PAST TWO YEARS, I HAVE HAD TO REPLACE THEM 5 TIMES ON THE DRIVER SIDE AND 2 TIMES ON THE PASSENGER SIZE. ALSO HAD MY HEAD LIGHT HARNESS REPLACED OCT DUE THE BLUB BREAKING IN MULTIPLE PIECES. JAN OF 2019, IT RAINED AND MY TURNING SIGNAL BLUB BROKE AGAIN AND THE LIGHTING COMPONENT FILLED UP WITH WATER AND LOOKED LIKE A FLOATING FISH BOWL.

WE BOUGHT THIS USED CAR FROM A DEALER DROVE IT ABOUT 4 TO 5 MONTHS AND THE LEFT SIGNAL LIGHT FAILED, SO WE CHANGED IT WORKED FOR ONE DAY AND THEN WENT DEAD AGAIN. TURNING LEFT FROM MY STREET THE STEERING WAS REALLY HARD AND HAD PROBLEMS TURNING LEFT BUT I DID FINALLY ON ANOTHER OCCASION THE SAME THING HAPPENED. FINALLY DRIVING SUDDENLY WE SAW A TURN ENGINE OFF AND THE ENGINE STARTED MAKING LOUD NOISES AND WENT DEAD IN THE MIDDLE OF THE STREET. SO WE KEPT GLIDING WITH NO ENGINE RUNNING AND WENT INTO A PARKING LOT. LUCKY FOR US THE CAR STOPPED RIGHT IN THE PARKING LOT. HAD TO BE TOWED FEW MILES TO A MECHANIC THAT TOLD US THE TIMING CHAIN IS BROKEN AND IN NEED FOR NEW ENGINE. WE TOWED IT TO ANOTHER MECHANIC AND THE SAME THING WAS TOLD. SO NOW IT IS BEEN SITTING AT THE MECHANIC'S SHOP FOR TWO WEEK WAITING FOR NEW ENGINE TO COME IN . I CAN NOT BELIEVE THAT AROUND 84000 MILES THIS CAR NEEDS A NEW ENGINE AND IT IS NOT CHEAP AT ALL. THE CAR HAS A SALVAGE TILTE BUT THIS DOES NOT HAVE ANYTHING TO DO WITH THE PROBLEMS SINCE TOO MANY PEOPLE HAVE BEEN DOCUMENTING THIS PROBLEM, STEERING, ELECTRICAL AND FAILED ENGINE. WHY GM DID NOT RECALL THESE CARS FOR THESE FAILURE. THEY ARE PUTTING PEOPLE AND FAMILIES AT RISK AND WE ARE STUCK WITH THE REPAIRS AND THE BILLS PILING UP.

THE LIFT GATE OPENS AND THEN IMMEDIATELY FALLS. IT HAS HIT ME IN THE HEAD A COUPLE OF TIMES. THE LIFT GATE CAN ONLY BE HELD UP IF IT IS PUSHED UP AS HIGH AS IT CAN GO. I AM SHORT SO THAT IS HARD FOR ME TO DO. I ALSO CAN'T LOAD/UNLOAD GROCERIES IF I'M HOLDING THE LIFT GATE UP. I LET THE LIFT GATE CLOSE PART WAY, HOLDING IT WITH MY BACK AS I TRY TO LOAD/UNLOAD GROCERIES, BUT NOW THE MOTOR IS PULLING IT CLOSED ON ME AND HAS TRAPPED ME UP AGAINST THE BUMBER! THE CAR IS ALWAYS PARKED WHEN WE OPEN/CLOSE THE LIFT GATE.

WHEN TEMPERATURES GO BELOW 20 DEGREES MY TRUNK DOOR WILL NOT OPEN ALL THE WAY WHEN I USE THE REMOTE OPENER. IT AUTOMATICALLY STARTS TO SHUT, EVEN WHEN SOMEONE IS ALREADY UNDER THE BACK TRUNK DOOR. I HAVE HAD SEVERAL INSTANCES WHERE THE TRUNK HAS CLOSED ON MY HUSBAND AND 9 YEAR OLD DAUGHTER. I HAVE HAD TO RUN OVER AND MANUALLY PUSH THE TRUNK OPEN FOR IT TO STAY OPEN. EVEN WHEN I TRY AND PRESS THE REMOTE OPENER AGAIN IT WILL NOT OPEN FULLY. THE ONLY WAY TO OPEN THE TRUNK IN TEMPERATURES BELOW 20 DEGREES IS MANUALLY.
