2018 BUICK ENCLAVE Complaints

DURING NORMAL COMMUTE, VEHICLE BEGAN BUCKING BADLY, WOULD NOT ACCELERATE AND BEGAN ROLLING BACKWARDS. CHECK ENGINE LIGHT ILLUMINATED. SHUT VEHICLE DOWN, RESTARTED, AND THE PROBLEM SEEMED TO CLEAR. BROUGHT VEHICLE TO DEALERSHIP, FOUND CODES P0011, P0014, P0021 AND P0024 SET. DEALERSHIP CONTACTED GM, WHO ACKNOWLEDGED THE ISSUE BUT OFFERED NO FIX. THEY ARE STILL STUDYING THE ISSUE AND HAVE NO RESOLUTION. DEALERSHIP CLEARED CODES AND RELEASED VEHICLE BACK TO US. ISSUE MAY RETURN AT ANY TIME. HOW CAN I TRUST MY FAMILY IN A VEHICLE THAT MAY SUDDENLY, WITHOUT WARNING, BEGIN BUCKING, STOP ACCELERATING AND CAUSE AN ACCIDENT? THIS IS AN UNSAFE CONDITION THAT GM NEEDS TO ADDRESS. I AM DISAPPOINTED THAT THEY HAVE NO RESOLUTION. DEALERSHIP REFERENCED BULLETIN PIP5569E, SO GM ACKNOWLEDGES THE ISSUE. I FOUND REFERENCES FROM ALMOST A YEAR AGO TO THIS ISSUE VIA GOOGLE - THAT'S VERY DISCONCERTING THAT, IN THIS TIME, GM CANNOT IDENTIFY A FIX.

I DROVE OVER SOME METAL COVERING OF A POT HOLE OR OTHER TYPE OF HOLE ON LEXINGTON AVENUE AND ABOUT 100TH STREET IN NYC TODAY. WHEN I DROVE OVER THE METAL COVERING THE CAR STOPPED. THIS IS THE AVENIR MODEL WHICH HAS AUTO STOP. THANKFULLY, THE CAR BEHIND ME STOPPED AND DIDN'T HIT ME. I WILL TAKE THE CAR IN TO BE EXAMINED BUT I THINK IT'S A MALFUNCTION OR ISSUE WITH THE AUTO STOP. WHEN I CALLED THE DEALER, THEY SAID IT WAS NOT THE CAR'S FAULT. I WANTED TO REPORT IT IN CASE THERE ARE OTHER COMPLAINTS CONCERNING SIMILAR ISSUES. THE DEALER CLAIMS THAT THEY HAVEN'T SEEN THIS ISSUE.

THERE ARE TWO ISSUES: WHILE BACKING UP THE CAR, ESPECIALLY DOWN A HILL, THE BRAKES DO NOT WORK/ENGAGE TEMPORARILY. EVENTUALLY THE BRAKES ENGAGE, BUT YOU TRAVEL FURTHER THAN YOU INTEND. THE "SERVICE BRAKE SYSTEM" LIGHT APPEARS ALSO. THIS IS AN INTERMITTENT PROBLEM. THE SECOND BRAKING ISSUE IS THAT THE EMERGENCY BRAKE WILL ENGAGE WITHOUT THE BUTTON BEING PRESSED. IT JUST HAPPENS AND IT THE EMERGENCY BRAKE IS DIFFICULT TO TURN OFF, THE CAR MAY NEE TO BE TURNED OFF ON BACK ON TO FIX. THE "SERVICE EMERGENCY BRAKES" LIGHT APPEARS. THIS HAS HAPPENED WHILE BACKING UP AND IN FORWARD IN NORMAL DRIVING CONDITIONS.

THE "START STOP" FEATURE CAUSED A LIFE THREATENING HESITATION UPON ACCELERATION FROM A FULL STOP AT AN INTERSECTION. ENCLAVE DOES NOT OFFER ANY OVERRIDE FOR THIS OPTION. THERE MUST BE A FIRMWARE UPDATE PROVIDED BY GM TO ALLOW IT TO BE DISABLED!!! THIS IS GOING TO KILL SOMEBODY!!!

2018 BUICK ENCLAVE. CONSUMER WRITES IN REGARD TO ENGINE SHUTING DOWN WHEN VEHICLE STOPS. *AS THE CONSUMER STATED THE START STOP FEATURE INTERMITTENTLY SHUTS DOWN THE ENGINE WHEN THE VEHICLE IS IDLE AND DOES NOT RECOVER QUICK ENOUGH FOR SAFE STARTS IN TRAFFIC. *JS

I WAS STOPPED AT AN INTERSECTION AT A TRAFFIC LIGHT & WHEN THE LIGHT TURNED GREEN, I TURNED LEFT & I'M UNCERTAIN IF MY EMERGENCY BRAKES KICKED ON OR IF MY CAR SIMPLY STALLED OUT, BUT MY CAR SUDDENLY WOULD NOT MOVE. MY PURSE, IN THE PASSENGER SEAT FLEW FORWARD & HIT THE FLOOR OF THE VEHICLE. THE CAR BEHIND ME AT THE LIGHT NEARLY REAR ENDED ME, BUT FORTUNATELY DID NOT. WE BROUGHT THE VEHICLE TO JIM ELLIS BUICK TO BE SERVICED, BUT THEY SAID IT APPEARED FINE & WAS CONFUSED. I DEFINITELY WAS NOT IN ANY DANGER OF HITTING ANYTHING WHEN TURNING AT THE INTERSECTION. THIS INCIDENT HAS MADE ME UNEASY WHEN OPERATING MY CAR.

TL* THE CONTACT OWNS A 2018 BUICK ENCLAVE. WHILE THE VEHICLE WAS AT A STOP, IT STALLED AND HESITATED TO MOVE. THE CONTACT STATED THAT THE AUTOMATIC STOP FEATURE ON THE VEHICLE CAUSED THE FAILURE. THE VEHICLE WAS TAKEN TO CANNON CHEVROLET BUICK CADILLAC (100 N THACKER LOOP, OXFORD, MS 38655, (662) 550-4208) WHERE THE CONTACT WAS INFORMED THAT THE VEHICLE WAS BUILT WITH THE AUTOMATIC STOP FEATURE AND THERE WAS NO REMEDY TO REPAIR THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THERE WAS NO REMEDY. THE FAILURE MILEAGE WAS APPROXIMATELY 3,500. CONSUMER STATED THE ENGINE AUTO STOP FEATURE CAUSES ENGINE TO GO DEAD EVERY TIME I COME TO COMPLETE STOP. ENGINE STARTS AFTER BREAK IS RELEASED. ON 9/22/18 ENGINE STOPPED WHILE CROSSING A 4 LANE HIGHWAY. UPDATED 10/26/18*JP

I WAS DRIVING ON A HIGHWAY 6 IN WATERLOO INDIANA AND MY SUNROOF EXPLODED AND THE ENTIRE GLASS WAS SHATTERED AND HAD A HUGE HOLE. THE EXPLOSION WAS LIKE A SHORT GUN GOING OFF. I THOUGHT SOME ONE SHOT OR THREW SOMETHING BUT THERE WAS NO OVERPASS. I CALLED THE POLICE JUST TO MAKE SURE AND A REPORT WAS FILED

PREMIUM PACKAGE COMES WITH SAFETY ALERTS. HOWEVER THREE OF THE ALERTS DO NOT PROVIDE ANY OF THE SAFETY FUNCTION DESCRIBED. FRONT COLLISION ALERT - HAVE HAD THREE EMERGENCY BRAKING SITUATIONS AND IN ALL THREE WHERE THE RED BEEPING ALERT IN THE DASH DID NOT FUNCTION. TESTED BY GM ENGINEER AND HE COULD NOT MAKE IT WORK AT OVER 20 MPH. ICONS IN INSTRUMENTION LIGHT UP SO IT IS SEEING CARS BUT NO WARNING AT STATED. FRONT PEDESTRIAN ALERT - SIMILAR TO ABOVE, CAR IS SEEING PEDESTRIAN BECAUSE ICONS LIGHT UP GREEN AND AMBER BUT FLASHING RED AND BEEPING DO NOT OCCUR WHEN YOU GET IN DANGER ZONE LANE DEPARTURE WARNING - THERE IS NOT BEEPING WHEN YOU CROSS A LANE WITHOUT USING TURN SIGNAL. LAND ADJUSTMENT WORKS SO VEHICLE IS SEEING LINES BUT IF YOU CROSS THE LINE WITHOUT ANY MANUAL EFFORT THE ALERT DOES NOT WORK A GM ENGINEER FOR THE HOUSTON AREA DROVE THE CAR AND COULD NOT GET ANY OF THESE FUNCTIONS TO WORK. HE CALLED GM AND WAS TOLD NOT TO TEST THIS THE FRONT COLLISION IN THE FIELD BUT THAT IT WAS TESTED AT FACTORY AND WORKED AS DESIGNED. SO GM SAYS THERE IS NOT ISSUE EVEN THOUGH I HAVE HAD 4 SITUATIONS WHERE IT SHOULD HAVE WORKED AND THE GM ENGINEER COULD NOT GET ANY OF THEM TO WORK AS OTHER GM CARS. OTHER ENCLAVES ON THE LOT ALL HAVE THE SAME ISSUE, SO IT IS EITHER A DESIGN FLAW OR A PROGRAMMING ISSUE, IN ANY EVENT IT IS A SAFETY FEATURE THAT IS NOT WORKING AS DESCRIBED OR AS IN OTHER GM CARS I OWN. THEY ARE NOT WILLING TO DISCUSS IT ANYMORE BECAUSE EVEN THOUGH IT DOES NOT WORK IN THE FIELD FOR HIM OR ME, THEIR ENGINEER SAID IT IS WORKING AS DESIGNED.

I WAS DRIVING THE CAR AND WHEN I DEPRESSED THE BRAKES THE BRAKES DID NOT ENGAGE. THE DASHBOARD ILLUMINATED WITH A "BRAKE ASSIST: ALERT AND I COULD FEEL THE ABS BRAKES ENGAGE. LUCKILY THIS HAPPENED WHILE I WAS PULLING INTO A PARKING LOT. ONLY HAD 1,200 MILES. HAD VEHICLE TOWED TO DEALER. CHECK ENGINE LIGHT DID COME ON AND SHOWED CODE P0557. THEY REPLACED THE CRANK SHAFT POSITION SENSOR WIRING HARNESS AND 2 GASKETS, BASED ON A REPAIR BULLETIN AND THEN BEFORE I COULD GET THE VEHICLE HOME IT HAPPENED AGAIN. NO BRAKES, BUT BRAKE ASSIST ACTIVATED AND ABS WAS ABLE TO STOP THE VEHICLE. CHECK ENGINE LIGHT CAME ON AGAIN AND SHOWED CODES P0557, U0401, U0121, & U0078. HAD VEHICLE TOWED TO DEALER AGAIN. THIS TIME THEY REPLACED PART # 84341899. LUCKILY BOTH INSTANCES HAPPENED AT LOW SPEEDS AND I WAS ABLE TO SAFETY MANEUVER THE VEHICLE TO A PLACE WHERE I COULD GET TOWED AND NOBODY WAS IN FRONT OF ME.
