2011 Buick Enclave Powertrain & Transmission Problems

I have had my car looked at and my camshaft reductor wheel/valve is broken. This happened very unexpectedly and almost caused a serious accident at highway speeds. I was able to drift the car to the shoulder from the middle lane, but almost was hit by a semi when my car randomly stalled out in the middle of I-5. This is a problem I have sense researched and has happened to many others with the same car and model year.

I was driving and the other person ran the stop light and hit my car making me go in and hit another car from the other side.

While driving at highway speeds, with cruise control set the vehicle started to violently shake almost causing me to lose control of the vehicle. After having the vehicle inspected I was informed that the transmission is known to have an issue with the 3rd and 5th clutch pack causing the vehicle to shake when they are trying to engage. This is no lights on the dash and no other warning signs of said issue. I have an appointment to have the issue resolved which entails to have the transmission either rebuild or replaced.

TRANSMISSION NEEDED REPLACED AT 160,000, ISSUE BEEN GOIN ON FOR ABOUT 1 YEAR OR 10,000 MILES HAS HAD OIL LEAKS, HAVE HAD TO FILL FUILD UP REGULARLY, SEEMS LIKE ALL OF THESE GM, CHEVY, BUICK AND SATURN'S ALL HAVE HAD THE SAME ISSUE WITH TRANSMISSIONS

IN 2017 THE TIMING BELT FAILED WITH LESS THAN 100,000 MILES ON THE VEHICLE. TIMING BELT REPLACEMENT WAS OVER 2000 DOLLARS. 2018 THE CHECK ENGINE LIGHT CAME ON INDIA STING AN ISSUE WITH THE CAYTALIC CONVERTER. HAVE NOT REPAIRED BUT VEHICLE WILL DYE WHILE DRIVING. IT QUIT WORKING ON INTERSTATE AND I HAD TO COAST ACROSS FIVE LANES TO SHOULDER, WHERE I WAS ABLE TO RESTART VEHICLE. THIS ALSO HAPPENED ON 2 LANE HIGHWAY. 2020 AIRBAG LIGHT CAME ON, STAYED ON FOR A FEW DAYS AND WENT OUT. HIT BUMP IN ROAD AIRBAG LIGHT RETURNS.

CODES P0017 AND P0008 CAMSHAFT POSITION SENSOR AND CRANKSHAFT POSITION KEEPS COMING ON DRIVING AND PARKED RUNNING. EVEN AFTER REPLACING THE SENSOR.

HELLO - I AM WRITING AS A CONCERNED CONSUMER. I CURRENTLY OWN A 2011 BUICK ENCLAVE. TWO WEEKS AGO, WHILE DRIVING THIS VEHICLE IT STARTED MAKING A VERY LOUD KNOCKING NOISE. THE CAR THEN COMPLETELY SHUT OFF AND BECAME INOPERABLE WHILE DRIVING DOWN A HILL. WITH LOSS OF POWER STEERING AND THE INABILITY TO RESTART THE ENGINE IT BECAME A DANGEROUS SITUATION TRYING TO GET THE VEHICLE STOPPED AND SAFELY OFF THE ROAD. THE VEHICLE WAS TAKEN TO A GARAGE AND IT WAS DETERMINED THAT THE ISSUE WAS A BROKEN TIMING CHAIN. THIS REPAIR REQUIRED THE REMOVAL OF THE ENGINE TO REPLACE THE TIMING CHAIN. RESEARCH INTO BUICK HAS SHOWN THAT THERE IS A BULLETIN OUT FOR THIS VERY ISSUE BUT ONLY FOR THE 2009 MODEL YEAR. MY 2011 WAS MANUFACTURED IN 2010. FOR THIS VERY ISSUE, BUICK HAS EXTENDED THE MANUFACTURES WARRANTY TO 120K OR 7YRS. RESEARCH SHOWS THAT THIS TIMING CHAIN ISSUE IS NOT EXCLUSIVE TO THE 2009 AS OWNERS OF OTHER MODEL YEARS ARE EXPRESSING THE SAME CONCERNS. I AM WRITING TO FILE A FORMAL COMPLAINT, AS THIS IS A SAFETY ISSUE THAT BUICK REFUSES TO ACKNOWLEDGE. THE FAILURE OF THIS TIMING CHAIN LEAD TO A SITUATION THAT COULD HAVE CAUSED A WRECK AND POSSIBLE INJURY. I HAVE CONTACTED BUICK SEVERAL TIMES AND THEY REFUSE TO PROVIDE FINANCIAL COMPENSATION FOR THE REPAIRS AND REFUSE TO INVESTIGATE THIS FURTHER. THEIR RESPONSE IS SIMPLY, THERE IS NO BULLETIN SO THERE IS NOTHING THAT CAN BE DONE FOR ME.

I WAS DRIVING DOWN THE HIGHWAY AND ALL OF SUDDEN THE VEHICLE JERK BACK HARD AND I LOSS POWER AND STABILIZE SYSTEM SHUT DOWN AND COULD DRIVE NO MORE THAN 20 MILE AN HOUR. IT GOTTEN WORST THAT MY TRUCK IS JERKING AND SHAKING.

CAR RPM IS INCREASING AND LOWERING DURING DRIVING LIKE THE TRANMISSIO. IS PREPARING TO CHANGE GEARS CAUSING CAR TO LOSE POWER IN THE MIDDLE OF DRIVING SCARING ME DURING DRIVING. CAR IS IN MOTION

2011 BUICK ENCLAVE "ENGINE HOT A/C OFF" AND THEN "ENGINE OVERHEATED IDLE ENGINE" AND THEN "ENGINE POWER REDUCED" MESSAGES CAME ON IN QUICK SUCCESSION (W/IN LESS THAN 1.5 MILES) AT 10:00 P.M. I WAS DRIVING ON SUBURBAN STREETS WHEN THIS ISSUE OCCURRED. TOOK INTO DEALER FIRST THING THE NEXT MORNING AND WAS TOLD THE WATER PUMP WAS LEAKING AND NEEDED TO BE REPLACED. I MENTIONED APRIL 2013 TSB #13079 RELATED TO LEAKING WATER PUMP SHAFT AND WAS TOLD THAT HAD EXPIRED. WATER PUMP WAS SUBJECT OF EXTENDED WARRANTY COVERAGE FOR 2008-2010 ENCLAVES (#13091). WATER PUMP IS COVERED UNDER POWERTRAIN WARRANTY (100,000 MILES OR 5 YEARS -- MY VEHICLE HAS 79,738 MILES AND WARRANTY EXPIRED 10//15). CALLED BUICK CUSTOMER SERVICE TO INQUIRE ABOUT THIS ISSUE. WAS TOLD DEALERSHIP WOULD HAVE TO DETERMINE ANY FINANCIAL ASSISTANCE. I BELIEVE THE EVIDENCE SUGGESTS GM IS AWARE THERE IS A CONTINUING ISSUE WITH THE WATER PUMPS ON BUICK ENCLAVES MADE AFTER 2010 AND THERE SHOULD BE EXTENDED WARRANTY COVERAGE FOR THE FIX ON THESE VEHICLES, AS WELL.

WHILE I WAS GETTING READY TO MERGE ONTO A HIGHWAY I HEARD A "PINGING NOISE" THEN A "THUD". I IMMEDIATELY PULLED OVER TO FIND THE THE DRIVE TRAIN OR DRIVE SHAFT HAD JUST FALLEN OUT OF MY CAR ONTO THE ROAD. *JS

VEHICLE EXPERIENCE SEVERE ROLL BACK WHEN ON AN INCLINE. IT IS VERY DANGEROUS AND THAT HAS HAPPENED TO ME MULTIPLE TIMES AND I AM AFRAID THAT I WILL HIT THE CAR OR STRUCTURE BEHIND ME. READING BUICK FORUMS IT SEEMS LINE MANY OTHERS ARE EXPERIENCING THIS PROBLEM AS WELL. *TR

WHEN MY BUICK HAS BEEN ON INCLINE IN THE DRIVE OR REVERSE GEAR, MY BUICK ROLLS BACKWARDS OR FORWARDS DEPENDING ON THE DIRECTION OF THE INCLINE WITHOUT STOPPING. IT MAKES IT NECESSARY TO HOLD THE BRAKE WITH ONE FOOT AND ACCELERATE WITH THE OTHER. THE PROBLEM USED TO BE A SMALL ROLL BACK BUT HAS RECENTLY BECOME TO A POINT WHERE THE CAR DOESN'T STOP ROLLING. THIS IS EXTREMELY DANGEROUS AS IT DOES NOT ALLOW THE DRIVER TO HAVE CONTROL OF THE CAR. I'M EXTREMELY WORRIED IN RESIDENTIAL AREAS WITH DRIVEWAYS ON AN INCLINE AS IT WILL MAKE IT HARD TO STOP THE CAR IF A KID IS EITHER IN FRONT OR BEHIND THE CAR WHEN THIS OCCURS. *TR

WHEN CAR IS ON A INCLINE WHEN YOU TAKE YOUR FOOT OF BRAKE IT ROLLS BACKWARD,JUST PURCHASE THE CAR ON 8/8/2013 TOOK IT BACK TO DEALER THEY SAY THAT'S HOW IT IS,NOTHING WRONG.(SAFETY HAZARD??) *TR

TL* THE CONTACT OWNS A 2011 BUICK ENCLAVE. THE CONTACT STATED THAT AFTER STOPPING AT A STOP SIGN ON A FLAT ROAD AND SLOWLY DISENGAGED THE BRAKE, THE VEHICLE STARTED ROLLING BACKWARDS. THE CONTACT MENTIONED THAT A GREAT AMOUNT OF PRESSURE HAD TO BE USED IN ORDER FOR THE VEHICLE TO MOVE FORWARD. THE PROBLEM PERSISTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 73,000.

EVER SINCE I BOUGHT THIS VEHICLE IT ROLLS BACKWARDS WHEN IN PARK.,I TOLD THE DEALER ABOUT IT AND THEY SAY IT'S COMMON. WHAT EVER THAT MEANS. I PUT UP WITH THIS UNTIL NOW THAT I AM PARKING IT IN A SMALL GARAGE AND WHEN I PARK IT IT ROLLS BACK AND THE OVERHEAD DOOR HITS THE BUMPER AND FLIES BACK OPEN. ONE TIME I PARALLEL PARKED ON A INCLINE AND IT ROLLED BACK INTO THE CAR PARKED BEHIND ME.LUCK FOR ME NO REAL DAMAGE. GLAD I LIVE IN FLORIDA WHERE THERE ARE NOT TO MANY HILLS TO PARK ON. BUT EVERY TIME I GO ON VACATION IT GETS MORE AND MORE DANGEROUS. THERE HAS TO BE SOMETHING THAT CAN BE ADJUSTED OR TIGHTENED UP TO STOP THIS, PLEASE RESPOND TO MY PROBLEM AS TO WHAT CAN BE DONE.

VEHICLE ROLLS BACKWARDS WHEN I LET OFF BRAKE ON SLIGHT GRADE AT STOP. *TR

I AM NOT SURE WHERE TRANSMISSION FALLS IN THE ABOVE LIST. EVER SINCE I PURCHASED THE VEHICLE IT ROLLS BACKWARDS WHEN STOPPED ON A HILL. I HAVE TO USE BOTH FEET TO KEEP IT FROM ROLLING BACK AND HITTING THE CAR BEHIND ME. I WAS TRYING TO BACK UP IN A PARKING SPACE THAT WAS UP HILL AND IT ROLLS FORWARD ALSO. I ASKED THE DEALERSHIP NOT LONG AFTER I DISCOVERED THIS ISSUE AND THEIR RESPONSE WAS OH IT IS SUPPOSED TO DO THAT. I FIND THAT HARD TO BELIEVE, IT IS DANGEROUS. IT'S NOT LIKE THIS IS A 5 SPEED WITH A CLUTCH BUT THAT IS HOW YOU HAVE TO TREAT IT ON HILLS.

2011 BUICK ENCLAVE ROLLS UNABATED ON HILLS WHILE IN GEAR - DRIVE OR REVERSE. VERY HARD TO CONTROL. REQUIRES VERY QUICK MOVE FROM BRAKE TO ACCELERATOR AND "2-FOOT" DRIVING WHICH IS DANGEROUS AND WEARS BRAKES AND TRANSMISSION. THERE IS NO "HILL HOLD" FEATURE AND DRIVETRAIN PROVIDES NO RESISTANCE. *TR
