POWER TRAIN
LOSS OF ALL VEHICLE POWER WHILE TRAVELING ON THE FREEWAY AT HIGHWAY SPEEDS. VEHICLE CHECK ENGINE, POWER LIMITED, AND ELECTRIC MOTOR OVERHEAT WARNING LIGHTS COME ON. THE COMBUSTION ENGINE WILL NOT START, AND BATTERY POWER AVAILABILITY GOES TO ZERO. THIS IS VERY DANGEROUS TO PUBLIC HEALTH AND SAFETY DUE TO INSTANTANEOUS LOSS OF COMBUSTION ENGINE AND ELECTRIC BATTERY POWER WHILE IN FAST-MOVING HIGHWAY TRAFFIC. THERE ARE SEVERAL INSTANCES OF THIS SAME PROBLEM OCCURRING IN MANY CADILLAC OWNERS FORUMS, SO GENERAL MOTORS KNOWS THERE IS A PROBLEM WITH THEIR CT6 PHEV TRANSMISSIONS. THE FIX SEEMS TO BE REPLACING THE TRANSMISSION DUE TO A BAD CLUTCH PACK, BUT PEOPLE COULD GET HURT IF THIS ISSUE IS ALLOWED TO CONTINUE WITHOUT A PERMANENT SOLUTION.

VISIBILITY/WIPER
HELLO, ON AN ESTIMATED 8+ TIMES, I PUT MY VEHICLE INTO GEAR, DROVE OFF AND BOTH MY SIDE VIEW MIRRORS WERE IN THE CLOSED/UP POSITION. I HAVE LEARNED FROM GM SUPPORT THAT GM DID NOT DEVELOP SOFTWARE WHERE THE MIRRORS AUTOMATICALLY OPEN: WHEN EITHER OPENING THE DOORS OR PUTTING INTO GEAR. THIS IS EXTREMELY DANGEROUS AND I HAD NEVER EXPERIENCED ON MY FORMER MERCEDES E-350 LEASES, THIS SAFETY TECHNOLOGY WAS STANDARD. THE LATEST INCIDENT I WAS DRIVING ON A MAIN WEST TO EAST ROUTE FOR ABOUT 2 MILES, NEEDED TO GET INTO THE RIGHT LANE, WENT TO LOOK AT MY RIGHT MIRROR, AND IT WAS COMPLETELY FOLDED UP. IT WAS VERY, VERY DANGEROUS, ALMOST GOT ME REAR-ENDED SINCE I BRAKED HARD WHEN I NOTICED AND I ALMOST SIDE-SWIPED THE CAR TO MY RIGHT.

I PURCHASED THE USED 2017 CADILLAC CT6 IN MARCH 2019 WITH 24,192 MILES. IT WAS A CERTIFIED PRE -OWNED CAR BY THE DEALER. ADDITIONALLY I PURCHASED A CPO PROTECTION PLUS PROTECTION PLAN WITH THE CAR. I AM EXPERIENCING PROBLEMS WITH THE TRANSMISSION. DURING ACCELERATION AND DECELERATING THE CAR FEELS A HESITATION FOLLOWED BY A SIGNIFICANT SHAKE, SHUDDER, JERK, CLUNK OR HARD SHIFT. THE AUTO START STOP FEATURE IS NOT WORKING CORRECTLY. WHEN YOU COME TO A LIGHT THE ENGINE WILL TURN OFF AND WHEN IT RESTARTS IT WILL JERK INTO GEAR SO VIOLENT THAT IT FEELS AS THOUGH THE VEHICLE HAS BEEN HIT FROM BEHIND. ADDITIONALLY AT 35, 45, AND 55 MILES PRE HOUR THE VEHICLE MAKES A WHINING NOISE EITHER FROM THE TRANSMISSION OR DIFFERENTIAL. I HAVE HAD THE CAR IN FOR REPAIRS FOUR TIMES AT THE DEALERSHIP WITH NO SUCCESS ON CORRECTING THE PROBLEMS.

CAR WILL NOT RESPOND FOR AT LEAST 2 SECONDS DURING A SLOW, ROLLING STOP, WHEN TRYING TO ACCELERATE AGAIN. UNABLE TO PERFORM EVASIVE MANUEVER, IF NEEDED, SECONDARY TO THE DELAY TO ACCELERATOR INPUT. HARSH 2-1 DOWNSHIFTS ALSO AT SLOW SPEEDS AND CAN EVEN FEEL AS THOUGH YOU WERE STRUCK FROM BEHIND. HIGHWAY DRIVING IS EXCELLENT; CITY DRIVING CHALLENGING WITH THE TRANSMISSION. THE DRIVER HAS TO LEARN HOW TO DRIVE THIS VEHICLE. FIND IT VERY UNUSUAL AFTER OWNING 5 OTHER CADILLACS AND NEVER HAD THIS PROBLEM. I BOUGHT THIS CAR AS A PRE-OWNED CERTIFIED VEHICLE FROM CADILLAC DEALER. THE CAR HAD 650 MILES ON IT AND I TRULY BEATIFUL/SHOWROOM CONDITION. I HAD THE TRANSMISSION RE-FLASHED, WHICH PROVIDED PERHAPS A 1-2 DAYS RELIEF. I WILL CONTINNUE TO PERSUE WITH DEALER, BUT WANTED YOU GUYS TO BE AWARE. CADILLAC SHOULD FIX THE PROBLEM; NEW/DIFFERENT TYPE OF TRANSMISSION OR RE-WORK THE 8L45/8L90'S WITH DIFFERNET VLAVES/SOFTWARE OR BUY IT BACK FROM ME.

TRANSMISSION HAS A SIGNIFICATION CLUNK/HESITATION/DELAY SHIFTING UP FROM 1ST-2ND GEAR AND DOWN FROM 2ND-1ST GEAR. IN THE UPSHIFT, THE CAR VIOLENTLY LUNGES FORWARD ONCE THE ACCELERATION REV FROM THE PUSH OF THE PEDAL CATCHES UP WITH THE GEAR SHIFTING, NO MATTER HOW DELICATELY YOU MIGHT PUSH THE PEDAL. FEELS LIKE THE VEHICLE HAS BEEN HIT FROM BEHIND ONCE IT CATCHES. IN THE DOWNSHIFT, UPON BRAKING TO COME TO A STOP, THE CAR PULSATES AND LUNGES FORWARD AS WELL WHICH HAS CAUSED ME TO NEARLY HIT THE CAR IN FRONT OF ME ON SEVERAL OCCASIONS AND IF NO CAR IS IN FRONT OF ME IT HAS CAUSED ME TO CREEP OUT INTO THE INTERSECTION A BIT. THIS HAS HAPPENED REGULARLY SINCE MY ACQUISITION OF THE VEHICLE IN EARLY APRIL 2018 AND THE DEALER HAS REVIEWED AND ADVISED THAT IT SHIFTS JUST FINE.

RIGHT AFTER PURCHASE, THE NAV SCREEN KEPT FLICKERING, CAUSING A DISTRACTED DRIVER SITUATION AND A HAZARD. THE DEALER DID EVERYTHING THEY COULD PER GM GUIDELINES, BUT EVEN AFTER THE 1ST SERVICE VISIT, THE CAR WOULD SHUT DOWN IN DRIVE MODE, AS THE VEHICLE WAS IN MOTION. THEN THE VEHICLE WOULD NOT SHUT OFF USING THE POWER OFF BUTTON. GM IS TELLING THE DEALER, THE NAV FLICKERING SCREEN IS NOT A SAFETY HAZARD, HOWEVER I BEG TO DIFFER IF EVERY 2 MINS, A DRIVER IS FIXATED, FOCUSED ON THE SCREEN MORE SO THAN ON THE ROAD, WHICH HAS CAUSED ME TO RUN OFF THE ROAD A FEW TIMES. THIS IS A SERIOUS SAFETY HAZARD AND ELECTRICAL CONCERN THAT GM DOES NOT SEEM TO CARE ABOUT EVEN AFTER 60+ DAYS AT THE DEALERSHIP.

I HAVE HAD ISSUES WITH MY VEHICLE THAT INVOLVES HARD SHIFTING AT TIMES AND ALSO, THE VEHICLE SOMETIMES WILL LURCH QUITE ABRUPTLY. IT ACTUALLY FEELS AS IF THE VEHICLE WAS REAR ENDED. I HAVE TAKEN THE VEHICLE TO THE DEALERSHIP ON 4 OCCASIONS AND THEY WERE ONLY ABLE TO "REPLICATE" THE PROBLEM ONE TIME. THIS HARD SHIFT/LURCHING OCCURS USUALLY WHEN AT A STAND STILL AND, ONCE YOU REMOVE YOUR FOOT FROM THE BRAKE, VEHICLE MAY SHIFT HARD. IT DOESN'T MATTE WHERE I AM; WHETHER ON STREETS OR ON THE FREEWAY. IF VEHICLE IS STOPPED, THEN THIS HAPPENS ON OCCASION. IT DOESN'T MATTER IF I AM USING THE "AUTOHOLD" FEATURE OR NOT BUT IT DOESN'T SEEM TO OCCUR AS OFTEN IF I AM USING THE "SPORT" MODE WHEN DRIVING. THE LAST TIME THIS EVENT OCCURRED, THE DEALERSHIP KEPT THE CAR FOR 3 DAYS AND CLAIMED THAT THEY COULD NOT REPLICATE THE PROBLEM, BUT, I DROVE AWAY AND THE ISSUE OCCURRED WITH ME LESS THAN 2 MILES FROM THE DEALERSHIP. I HAVE 2 GRANDSONS THAT I "TAXI" AROUND AND THEY HAVE BOTH FELT THIS PROBLEM. AS A MATTER OF FACT, ANYONE WHO RIDES IN MY CAR IS AWARE OF THIS PROBLEM BUT, FOR SOME REASON, CADILLAC IS STATING THAT THERE IS NOTHING WRONG WITH THE VEHICLE. THE FIRST TIME THIS OCCURRED WAS ON 9/13/17; AGAIN ON 10/5/17. (TERM USED WAS CCND - CUSTOMER CONCERN NOT DUPLICATED). NOW, ON 11/03/17 THEY DUPLICATED
