2018 Chevrolet Traverse

I HAVE HAD ISSUES WITH MY 2018 TRAVERSE SINCE DECEMBER. THE PROBLEM STARTED AROUND 9,000 MILES. I TOOK MY VEHICLE INTO THE DEALERSHIP AND THEY COULD NOT DUPLICATE THE ISSUE. I WOULD PUT THE VEHICLE IN DRIVE AND THE "D" LIGHT WOULD BLINK BUT THE CAR WOULD NOT MOVE. IN MARCH AFTER SEVERAL TRIPS TO THE DEALERSHIP THEY FINALLY REPAIRED THE VEHICLE. THEY REMOVED THE TRANSMISSION AND REPLACED A SENSOR. THE VEHICLE DID NOT HAVE ANY ISSUES UNTIL JULY 23RD WHEN DRIVING ON A CITY ROAD THE CAR GOT STUCK IN FIRST GEAR. I WAS PUSHING THE GAS PEDAL AND THE CAR WOULD NOT GO OVER 20 MPH. I TOOK THE VEHICLE IN AND THEY REPLACED THE TCM AND SOLENOID SENSOR. I PICKED UP THE VEHICLE ON 8/8 ONLY TO RETURN ON 8/15 WHEN THE CAR STALLED AND JERKED WHILE I WAS DRIVING. ON 8/16 I SPOKE WITH THE DEALERSHIP WHO INFORMED ME CHEVROLET ADVISED THEM TO CLEAR THE CODE AND RETURN THE VEHICLE TO ME. THIS IS A KNOWN ISSUE TO THEM AND THE ENGINEERING DEPARTMENT IS WORKING ON FIGURING OUT THE PROBLEM. AS OF 8/18/2019 THIS VEHICLE HAS SPENT 47 DAYS IN THE SHOP FOR REPAIRS AND HAS 10 REPAIR ORDERS.

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.

TL* THE CONTACT OWNS A 2018 CHEVROLET TRAVERSE. WHILE ATTEMPTING TO TURN INTO A PARKING LOT, THE CHECK ENGINE INDICATOR ILLUMINATED AND THE VEHICLE LOST POWER. THE VEHICLE WAS TOWED TO HAMPTON CHEVROLET (757-325-9604, LOCATED AT 1073 W MERCURY BLVD, HAMPTON, VA 23666) WHERE THE TECHNICIAN PERFORMED A DIAGNOSTIC TEST AND FOUND CODES P0014 AND P0024. THE MANUFACTURER WAS MADE AWARE OF THE CODES AND ADVISED THE TECHNICIAN TO CLEAR THE CODES AND RETURN THE VEHICLE TO THE CONTACT. THE TECHNICIAN ACTED ACCORDINGLY. THE CONTACT STATED THAT THE MANUFACTURER AND THE TECHNICIAN STATED THAT THERE WAS NO REMEDY FOR THE FAILURE. THE CONTACT INSISTED THAT THE VEHICLE WAS NOT REPAIRED AND UNSAFE TO DRIVE. THE FAILURE MILEAGE WAS 4,571.

DRIVING LATE AT NIGHT WITH FAMILY DOWN A STATE HIGHWAY/CITY STREET WITH SOME STOPLIGHTS AND ROTARY, VEHICLE SUDDENLY SEEMS TO BE INTERMITTENTLY LOSING POWER OR TRANSMISSION SLIPPING WHEN DRIVING. WHEN GIVING GAS ENTERING ROTARY, INTERMITTENT SLIPPING/POWER LOSS (LIKE A SKIPPING POWER/SLIPPING TRANSMISSION) WORSENED - FELT GREATER LOSS OF POWER AND FOR SLIGHTLY LONGER PERIODS. NOTED ENGINE LIGHT CAME ON. WORSENING INTERMITTENT POWER FAILURE/SLIPPING/HESITATION/JERKING CONTINUED WHEN GIVING GAS TO ENGINE FOR ~1/4 MILE UNTIL PULLED INTO SHOPPING MALL PARKING LOT. FELT LUCKY TO BE ABLE TO REACH LOT, CALLED FOR FLATBED TOW TO DEALER. DEALER HAD VEHICLE FOR 1 WEEK, AND WHEN ASSESSMENT COMPLETE, REPORTED DTC P0011, P0014, P0021 AND P0024 CAM CODES. THEY VISUALLY INSPECTED WITH NO CONCERNS, TEST ACTUATOR SYSTEM OPERATING. SEARCH FOR BULLETINS REVEALED DOCUMENT 5251270 WITH NO REPAIR YET FOR ANOMALY, WHICH DESCRIBES "SOME CUSTOMERS MAY COMMENT THAT THE SES [SERVICE ENGINE SOON] LAMP IS ILLUMINATED. THIS LAMP MAY HAVE COME ON BY ITSELF OR IN SOME CASES, THE CUSTOMER MAY EXPERIENCE DRIVABILITY ISSUES SUCH AS A STALL, LURCH, STUMBLE, HESITATION OR POWER LOSS AFTER AN AUTO STOP/RESTART." NOTES TECHNICIAN MAY FIND THE ABOVE LISTED CODES. CAUSE IS LISTED AS "A SOFTWARE ANOMALY THAT ALLOWS THE 'VERIFY SYNC' STATUS TO NOT RESTART AND REACH FULL 'SYNC' WHEN THE ENGINE RESTARTS. THE ECM THEN REPORTS ACTUAL CAM POSITIONS AS '0' WHILE IT CONTINUES TO COMMAND THE ACTUATORS TO MOVE RESULTING IN ENGINE ROUGHNESS AND/OR DRIVABILITY CONCERNS (AS STATED ABOVE) WITH THE POSSIBILITY OF SETTING MULTIPLE CAM PHASER PERFORMANCE DTCS." INSTRUCTIONS ON THE BULLETIN ARE TO CHECK AND CLEAR CODES AND RETURN VEHICLE TO CUSTOMER. BULLETIN CREATED ON 5/7/2018 WITH 5 UPDATES SINCE. BROUGHT VEHICLE BACK TO DEALER DUE TO CONCERNS OF LACK OF FIX AND SAFETY WHEN RECURS, DEALER UNABLE TO REPLICATE.

CAR HAD ABOUT 10000 MILES AND IN TWO SEPARATE OCCASIONS HAS STALLED, STEERING WHEEL HAD STOP WORKING, COULDN'T STEER, CAR TURNS OFF WHEN STOPPED AT TRAFFIC LIGHTS, ALRMS GO OFF AND DEALER JUST SAYS THEY CAN ONLY REPROGRAM THE COMPUTER, NO REPAIRS AVAILABLE. ON A THIRD TIME BRAKING SYSTEM ALARMS WENT OFF AND DEALER HAD TO REPLACE THE BRAKING SYSTEM. VEHICLE HAS ALWAYS FAILED WHILE IN MOTION. DEALER AND MANUFACTURER WILL BE RESPONSIBLE IF SOMEONE GETS HURT BECAUSE THIS CAR DOES NOT FUNCTION AS IT SHOULD.

IN EARLY APRIL 2019, APPROXIMATELY THE FIRST WEEK OF APRIL, I WAS DRIVING THE TRAVERSE ON A HILL AND STOPPED AT A STOP LIGHT. WHEN THE LIGHT TURNED GREEN, I ATTEMPTED TO STEP ON THE GAS AND PULL FORWARD, BUT THE CAR ROLLED BACKWARDS. I LOOKED DOWN TO SEE IF I WAS IN REVERSE, BUT THE CAR WAS IN DRIVE. THIS SPECIFIC INCIDENT OCCURRED A TOTAL OF TWO TIMES. ON APRIL 23, 2019 AROUND 9:40 AM I WAS DRIVING AND MY CAR STALLED MULTIPLE TIMES DURING THIS TRIP. I WAS NOT SURE IF THE CAR WAS GOING TO MAKE IT TO MY FINAL DESTINATION. THE CHECK ENGINE LIGHT ILLUMINATED. ON APRIL 24, I RECEIVED A CALL FROM THE DEALERSHIP. THE DEALERSHIP INFORMED ME THAT THE CAR SHOWED 4 'CODES'. P0011 'A' CAMSHAFT POSITION ' TIMING OVER-ADVANCED OR SYSTEM PERFORMANCE BANK 1 P0014 'B' CAMSHAFT POSITION ' TIMING OVER-ADVANCED OR SYSTEM PERFORMANCE BANK 1 P0021 'A' CAMSHAFT POSITION ' TIMING OVER-ADVANCED OR SYSTEM PERFORMANCE BANK 2 P0024 'B' CAMSHAFT POSITION ' TIMING OVER-ADVANCED OR SYSTEM PERFORMANCE BANK 2 THESE CODES REPRESENTED A SOFTWARE PROBLEM RELATED TO THE ENGINE. TIM INFORMED ME THAT ACCORDING TO THE GM BULLETIN (PIP5568E OR DOCUMENT ID# 5251270), THE RECOMMENDATION IS TO DELETE THE CODES AND THAT THERE IS NOT A SOFTWARE SOLUTION TO THE PROBLEM AT THIS TIME. THE DEALERSHIP INFORMED ME THAT BECAUSE OF THE SEVERITY OF THE SYMPTOMS I WAS EXPERIENCING RELATED TO THE CODES HE DID NOT FEEL COMFORTABLE WITH THE RECOMMENDATION FROM THE GM BULLETIN AND HE WOULD BE ESCALATING THE ISSUE TO THE GM DISTRICT MANAGER. THE ULTIMATE RESULT IS THAT THEY WANT TO DELETE THE CODES AND HAVE ME COME PICK UP THE CAR AS THERE IS NO SOLUTION TO THE ISSUE AT THIS TIME.

ON A NORMAL SUNNY AFTERNOON AFTER ABOUT DRIVING FOR 20 OR SO MILES, WE WERE APPROACHING A RED LIGHT IN A LINE OF TRAFFIC AT A BUSY INTERSECTION, THE VEHICLE APPEARED TO START SLIGHTLY JERKING AS I WAS COMING TO A STOP. ONCE STOPPED THE STOP/START FUNCTION OPERATED. UPON RELEASING THE BRAKE TO ACCELERATE THRU THE INTERSECTION THE VEHICLE STARTED JERKING AND LURCHING UNCONTROLLABLY THEN SHUT DOWN COMPLETELY, THE INSTRUMENT PANEL WENT DARK. I COULD NOT GET THE CAR OUT OF THE LINE OF HEAVY TRAFFIC, I HAD TO PUT IT IN PARK RIGHT IN THE MIDDLE OF THE ROAD AND TRY THE START BUTTON. THANKFULLY THE VEHICLE STARTED, THE CHECK ENGINE LIGHT CAME ON AND STAYED ON BUT THE VEHICLE APPEARED TO BE RUNNING NORMAL AGAIN AND WE WERE ABLE TO PROCEED. THIS WAS VERY UPSETTING AND DANGEROUS AS IT OCCURRED IN HEAVY TRAFFIC AT AN INTERSECTION. I TOOK IT BACK TO THE DEALERSHIP THE NEXT DAY (I BOUGHT THIS VEHICLE USED 2 WEEKS PRIOR, THIS WAS ONLY MY 2ND TIME DRIVING IT AND I HAD ONLY PUT 70 MILES ON IT IN THE 2 WEEKS I HAD IT). THE CURRENT MILEAGE IS APPROX. 25,600. THE HARD CODE THE DEALER RETRIEVED NOTED A CAMSHAFT SENSOR ISSUE. THE SENSOR WAS NOTREPLACED, I WAS TOLD THAT GM IS AWARE OF THIS PROBLEM AND WOULD BE ISSUING A RECALL BUT THEY ARE NOT SURE WHEN. THEY SAID IT WAS A COMPUTER PROGRAM ISSUE. I AM VERY CONCERNED FOR OUR SAFETY WHILE OPERATING THIS VEHICLE AS THEY SAID THE ISSUE MAY OR MAY NOT HAPPEN AGAIN. ONSTAR SENT ME AN EMAIL NOTIFYING ME THAT MY 2018 CHEV TRAVERSE HAD AND ENGINE/TRANSMISSION ISSUE AND TO TAKE IT TO THE DEALER ASAP . THANK YOU ONSTAR, I AM VERY AWARE OF THE ISSUE AND IT WAS ALREADY AT THE DEALER BUT I APPRECIATE THAT YOU ALSO RECOGNIZE THAT THERE WAS A PROBLEM. HOPING GM DOES SOMETHING VERY SOON, THIS IS A $50,000 VEHICLE WITH ONLY 25K MILES ON IT AND IT IS NOT SAFE TO OPERATE UNDER THESE CONDITIONS.
