2018 Chevrolet Traverse

I WAS STOPPED AT AN INTERSECTION AND THE TRANSMISSION DID NOT ALLOW THE VEHICLE TO MOVE FORWARD, IT APPEARED TO DISENGAGE EVEN THOUGH THE SHIFTER AND DASH ICON WERE SET IN "DRIVE" MODE. THERE IS ALSO AN ALARM SOUNDING WHEN I SHUT THE VEHICLE MOTOR OFF AND THE DASH SCREEN READS "SHIFT TO PARK". I FOUND THAT I NEED TO RESTART THE VEHICLE AND SHIFT OUT AND BACK IN TO "PARK" IN ORDER FOR THIS ALARM TO SHUT OFF. IT APPEARS THERE IS A BAD CONNECTION BETWEEN THE COMPUTER AND THE TRANSMISSION OR VISA VERSA. GM HAS ALREADY ISSUED SEVERAL TSBS RELATED TO THIS VEHICLE AS YOU MIGHT BE AWARE.

ON OCTOBER 1, 2018 I PURCHASED A NEW TRAVERSE FROM KELLEY CHEVROLET OF FORT WAYNE INDIANA. MY QUESTION IS CAN THE AUTO STOP ON MY NEW 2018 CHEVROLET TRAVERSE BE DISABLED. I JUST HAD A CLOSE CALL INVOLVING THE AUTO STOP. I WAS IN BRANSON MO ON VACATION AND THIS PLACE IS BUILT ON HILLS AND MORE HILLS. I HAD COME TO A STOP ON A HILLSIDE AND THE CAR WENT TO AUTO STOP. WHEN I LIFTED MY FOOT ON THE BRAKE SO AUTO STOP WOULD NOT BE ENGAGED THE ENGINE STOPPED. I HAD NO BRAKES OR STEERING OF THE VEHICLE AND IT STARTED ROLLING BACKWARD ' THANK GOODNESS THERE WERE NO CARS BEHIND ME. THE VEHICLE WAS ROLLING TOWARD A VERY STEEP HILL ON THE SIDE OF THE ROAD AND WITH NO BRAKES I COULD NOT STOP. INSTEAD I PULLED HARD ON THE STEERING WHEEL AND GOT IT CROSSWISE STOPPED IN THE MIDDLE OF THE ROAD. IT TOOK ME SEVERAL TIMES BEFORE I COULD GET THE ENGINE STARTED. AUTO STOP IS A PAIN IN THE BUTT AND THIS SCARED THE DICKENS OUT OF ME. CAN IT BE REPROGRAMMED TO NOT WORK?

VEHICLE WAS STOPPED ON A STEEP CITY STREET BEHIND ANOTHER VEHICLE TURNING LEFT. VEHICLE WENT TO MOVE FORWARD AND TURN LEFT AND IT SHUT OFF AND ROLLED BACKWARDS DOWN THE STEEP HILL. WHEEL COULD NOT BE TURNED, BRAKES COULD NOT BE PRESSED, WHEN GAS WAS PRESSED IT DID NOT GO FORWARD, IT ROLLED BACKWARDS IT WAS LIKE IT SHUT OFF AFTER BEING IN AUTO STOP MODE. PARKING BRAKE ASSIST CAME ON AUTOMATICALLY AND VEHICLE ROLLED INTO A CEMENT POLE. VEHICLE WAS ABLE TO BE RESTARTED. PARKING BRAKE WOULD NOT RELEASE. HAD TO SHUT OFF VEHICLE, RESTART AND TRIED TO RELEASE PARKING BRAKE 5 MORE TIMES BEFORE IT RELEASED. THIS VEHICLE OFTEN ROLLS BACKWARDS AFTER BEING IN AUTO STOP MODE AND THE GAS NEEDS TO BE PUSHED HARD IN ORDER FOR IT TO GO FORWARD. THIS VEHICLE FEELS LIKE IT SLOWS DOWN WHEN PRESSING THE GAS AT TIMES AND YOU NEED TO PUSH THE GAS PEDAL HARDER. THE BRAKES SQUEAK OFTEN WHEN WET AND COLD AND SOMETIMES WHEN STARTING THE VEHICLE THE BRAKE WILL NOT ALLOW YOU TO PUSH IT DOWN, YOU HAVE TO PUSH IT SEVERAL TIMES, LET UP AND PUSH IT AGAIN BEFORE THE VEHICLE WILL START.

WHEN I ATTEMPT TO TURN MY VEHICLE OFF, I GET A MESSAGE ON THE SCREEN THAT SAYS TO PUT THE CAR IN PARK. I VERIFIED THAT THE CAR IS IN PARK AND THE SCREEN READS THAT IT IS. THE MESSAGE CONTINUES, AND THE VEHICLE WILL NOT ALLOW ME TO SHUT ANYTHING OFF OR LOCK THE VEHICLE. THE VEHICLE JUST CONTINUES TO CHIME. THE ONLY RECOURSE IS TO DISCONNECT THE BATTERY. BUT THEN, I CANNOT LOCK THE VEHICLE. I HAVE INCLUDED A PICTURE OF THE SCREEN TO SHOW WHAT I AM SEEING. I HAVE SEEN SEVERAL ISSUES ONLINE REGARDING GM VEHICLES WITH THIS ISSUE. I WAS TOLD BY THE DEALERSHIP, WHO HAS LEFT ME STRANDED WITHOUT A CAR, THAT THEY HAVE SEEN THIS BUT THERE ARE NOT ENOUGH ISSUES OUT THERE TO WARRANT A RECALL. IT WOULD SEEM TO ME THAT THIS IS A SAFETY ISSUE THAT SHOULD REQUIRE IMMEDIATE ATTENTION.

MULTIPLE INSTANCES HAVE OCCURRED WHERE ENTERTAINMENT SYSTEM AND OTHER AREAS OF DASH RANDOMLY SHUTDOWN WHILE DRIVING. MUSIC CAN NOT BE PLAYED, TURN SIGNAL SOUNDS ARE NO LONGER HEARD, AND VOICE OPERATIONS DO NOT WORK. TURNING CAR ON AND OFF DOES NOT SOLVE PROBLEM, HOWEVER AFTER SITTING OVER NIGHT SEEMS TO WORK NORMAL. MOST RECENT TWO INSTANCES HAPPENED SEPTEMBER 14TH, 2019 AND SEPTEMBER 8TH, 2019 SO JUST A WEEK APART.

BEGAN 6/19, WITH PROGRESSIVE WORSENING. WHEN THE VEHICLE IS PLACED INTO PARK AND SHUT-OFF, A WARNING APPEARS ON THE INFO DISPLAY STATING" SHIFT TO PARK". AT WHICH POINT THE VEHICLE KEEPS ALL LIGHTS ON THE INSIDE AND OUTSIDE OF THE VEHICLE ILLUMINATED, THE AC STAYS ON, THE RADIO/ENTERTAINMENT DISPLAY STAYS ON, IN ADDITION TO A WARNING BEEP/CHIME THAT IS TYPICAL WHEN THE VEHICLE IS LEFT "ON" AND YOU OPEN THE DOOR. IN OTHER WORDS, OUR VEHICLE STILL THINKS IT IS "ON" AND "IN" GEAR. IN THE BEGINNING IT WOULD TAKE 2-5 TIMES OF TURNING THE VEHICLE BACK ON AND OFF IN ORDER FOR THE WARNING TO GO AWAY AND THE VEHICLE TO SHUT-OFF PROPERLY. NOW, IT WILL NO LONGER SHUT-OFF REGARDLESS OF HOW MANY TIMES THE ENGINE IS RESTARTED AND THE STICK-SHIFT IS MOVED OUT OF PARK & BACK. HAVE RESORTED TO UNPLUGGING THE BATTERY EVERY TIME WE EXIT THE VEHICLE TO KEEP IT FROM BEING DRAINED. THE VEHICLE HAS ALSO NOT RE-STARTED AT ALL(TAKING 15 MINUTES OF RE-ENGAGING THE STARTER BUTTON AT ITS WORST). LEAVING MY WIFE & TODDLERS STUCK IN 100PLUS DEGREE HEAT. WHEN IT DOES NOT RE-START, THE DASH DISPLAY READS THE VEHICLE AT "0 MPH" AND ALLOWS THE GEARS TO BE SHIFTED. THERE ARE NUMEROUS OTHER PEOPLE ONLINE STATING SIMILAR ISSUES. SOME HAVE RESOLVED WITH A CHANGE OF THE SHIFTER MECHANISM, & OTHERS STILL WITH CONTINUED ISSUES AFTER THAT. THE DEALERSHIP STATED THERE IS ONLY 1 PART LEFT IN TOWN, AND THAT IT IS ON BACK-ORDER AND THEY CAN'T GET IT FROM THE MANUFACTURER(THEY TRIED THEIR TWO NATIONWIDE WAREHOUSE LOCATIONS). NOT ONLY THAT, THE DEALERSHIP SAID WE NEEDED TO LEAVE THE VEHICLE WITH THEM AND THEY WOULD NOT EVEN "LOOK AT IT" FOR UP TO 1.5 WEEKS, AND THAT THEY WERE OUT OF LOANER VEHICLES. THE VEHICLE IS STILL UNDER WARRANTY, AND WAS PURCHASED CERTIFIED-USED. NOTHING HAS OCCURRED WHILE DRIVING THE VEHICLE OR WHEN STOPPED AT A LIGHT/STOP-SIGN, BUT WE CERTAINLY DON'T WANT TO FIND OUT WHAT "COULD" HAPPEN.

ISSUE 1 WHEN YOU STOP DRIVING THE TRAVERSE, PLACE IT IN PARK AND HIT THE BUTTON TO TURN OFF THE ENGINE, IT WILL SHUT OFF THE ENGINE BUT NOT THE ELECTRONICS. THE CAR DISPLAYS 'ACTION REQUIRED SHIFT TO PARK' EVEN THOUGH THE SHIFTER IS IN PARK WITH THE RED P LIT UP. YOU CANNOT TURN OFF THE VEHICLE UNTIL YOU REPEATEDLY START THE VEHICLE, PLACE IT IN DRIVE THEN BACK TO PARK. EVENTUALLY IT WILL WORK CORRECTLY. IT ALSO SEEMS TO CLEAR IF I SHIFT ALL THE WAY DOWN TO L THEN BACK TO PARK. ISSUE 2 RANDOMLY (BUT OFTEN) WHEN YOU START THE VEHICLE AND SHIFT IT INTO DRIVE THERE IS A LONG DELAY BEFORE THE VEHICLE SHIFTS IN GEAR. YOU SHIFT TO D AND HIT THE GAS AND THE ENGINE REVS LIKE IT'S IN NEUTRAL. LOOKING AT THE DISPLAY THE D KEEPS FLASHING THEN EVENTUALLY IT WILL STOP FLASHING AND THE VEHICLE WILL GO IN GEAR. THIS IS HAPPENING MORE AND MORE FREQUENTLY.
