2014 Buick Regal

AFTER COLD START THE BRAKE SYSTEM IS WEAK TO NON EXISTENT. WE HAVE A SLOPE OF APPROXIMATELY 25-30 DEGREES AND THIS CAUSED US TO GO INTO OUR NEIGHBORS YARD WHEN THE BRAKES ONLY SLOWED THE VEHICLE AND COULD NOT BRING IT TO A COMPLETE STOP. WE ARE CURRENTLY WORKING WITH OUR LOCAL DEALERSHIP TO GET THE PROBLEM FIXED, HOWEVER DIAGNOSIS IS PROBLEMATIC DUE TO THE FACT THAT IT ONLY OCCURS ON A COLD START AND THEN BECOMES A NON ISSUE. CURRENTLY YATES BUICK IN GOODYEAR AZ HAS BEEN DISMISSIVE AND UNHELPFUL WITH THIS PROBLEM AND BUICK CUSTOMER CARE LINE IS EQUALLY UNHELPFUL. I WILL UPDATE IF I CAN FIND A MECHANIC THAT CAN DIAGNOSE THE PROBLEM.

PURCHASED IN JAN 2021 WITH 94K MILES AND AS OF MAR 2021 96K MILES A CATASTROPHIC ENGINE FAILURE OF THE #4 CYLINDER. CRACK IN THE PISTON RING GROOVES AND NOW HAS ZERO COMPRESSION. WHILE DRIVING THE HIGHWAY AT 74 MPH. LOSS OF ENGINE POWER AND CHECK ENGINE LIGHT IS ON AND WILL STALL AT IDLE EVEN IN NEUTRAL WHILE SITTING AT A STOP LIGHT OR STOP SIGN. ENGINE OIL FOUND UNDER THE CAR AS WELL BUT NOT SURE SPECIFIC LOCATION AT THIS TIME. HEAVY BLUE SMOKE FROM EXHAUST AND VERY ROUGH IDLE WITH LACK OF RESPONSE FROM THE TURBO ALONG WITH THE TRACTION CONTROL LIGHT ON AS WELL.

MY BUICK PURCHASED NOVEMBER 2019 HAS THE MISFORTUNE OF HAVING THE 2.0 LTG 4CYL TURBO. THROUGH RESEARCH I HAVE LEARNED THAT CATASTROPHIC FAILURE WITH THE PISTONS IS A COMMON OCCURRENCE ACROSS THE GM PLATFORM WITH SAME ENGINES. THIS IS LIKELY CAUSED BY A MISFIRE OR PREIGNITION IN THE CYLINDER WHICH WHICH FEEDS ON ITSELF AS IT GETS WORSE. ALSO THE PCV SYSTEM DESIGNED FOR A NATURALLY ASPIRATED ENGINE NOT A TURBO ENGINE. THIS SYSTEM FUNCTIONS ONLY WHEN THERE IS NO BOOST FROM THE TURBO. THIS CAUSE GUNK TO BUILD UP EVENTUALLY BACK FLOWING INTO #1. SINCE LIQUID WILL NOT COMPRESS IT CREATES PRESSURE IN THE CYLINDER DAMAGING THE RINGS. I PURCHASED MY CAR USED WITH NO WARRANTY AND EXACTLY 100K. EVEN ON THE TEST DRIVE I FELT A MISFIRE BUT WAS TOLD IT'S NOTHING. MAYBE MY FOOT SLIPPED. FIVE DAYS LATER THE PREIGNITION HAPPENED AGAIN. CHANGE THE PLUGS AND WIRES AND THE PROBLEM WENT AWAY FOR AWHILE. THREE WEEKS LATER WHEN I COLD START THE ENGINE IN THE MORNING TO WARM UP. IT WAS EXHIBITING THE SAME MISFIRING ALONG WITH A FLUCTUATING IDLE AND EXCESSIVE FUEL BEING BLOWN OUT THE EXHAUST. PULLED THE CODES ALL IT SAID WAS MISFIRE IN #2. BROUGHT IT IN TO SERVICE SHOP. THEY PULLED THE CODES WITH NOTHING REPORTING. I WAS TOLD IT WAS A NORMAL SITUATION IN THE BUICKS. BEING NAIVE AND UNFAMILIAR WITH THE MOTOR I BELIEVED THEM. I DID FIND A GM SERVICE BULLETIN THAT DID SUPPORT WHAT THEY SAID. CLAIMED IT WAS DOUBLE IGNITING TO HEAT THE CATALYTIC CONVERTOR UP FASTER. THE ENGINE CONTINUED TO EXHIBIT THE SAME ISSUES ALL ALONG IM BEING TOLD NOTHING IS WRONG. FAST FORWARD TO LAST WEEK THE PROBLEM EXPONENTIALLY INCREASED. BROUGHT IT INTO THE DEALER. THEY COULDN'T "FIND" ANYTHING THOUGH THEY AGREED WASN'T RUNNING RIGHT. MARCH 7 ANOTHER DEALERSHIP. YEP SOMETHING IS WRONG BUT THE CAR IS NOT SAYING ANYTHING. THE TECH WENT FOR A TEST DRIVE AND THE MOTOR FAILED. A BORE SCOPE REVEALED SEVERE PISTON DAMAGE.

I WAS BACKING MY CAR INTO MY DRIVEWAY AND THEN I SHUT OFF ENGINE, RADIO STILL PLAYING, THEN ALL OF A SUDDEN LIGHTS STARTED DIMMING AND THE ANTI THEFT WENT INTO ACTION. WHOLE CAR SHUT DOWN, NOT EVEN REMOTES WOULD WORK. GOT THE HOOD OPENED AND DISCOVERED A MELTING WIRE CONNECTED TO THE NEGATIVE SIDE. THANK GOD I WAS HOME WHEN IT HAPPENED. COULD THIS HAVE CAUGHT FIRE INSIDE MY GARAGE? MY CAR IS CURRENTLY AT TURNER TOYOTA IN MONTROSE COLORADO. WAS INQUIRING IF THIS IS A MALFUNCTION WITH WIRING HARNESS. SO FAR ITS COSTING US 800.00 DOLLARS IN REPAIR, WHICH I DONT HAVE MY CAR BACK AS OF TODAY. I WOULD LIKE THIS MATTER CLOSELY LOOKED AT FOR A SAFETY RECALL DUE TO THE MATTER THINGS COULD HAVE BEEN ALOT WORSE.

I WAS DRIVING ABOUT 35 MPH ON CITY STREET AND MY CAR STARTING JERKING I LOOKED AT THE DASH THE GEAR HAD SHIFTED IT SAID 'MD' WHEN I LOOKED AT WHAT GEAR MY CAR WAS IN .

TL* THE CONTACT OWNS A 2014 BUICK REGAL. WHILE APPROACHING THE DRIVEWAY OF HER HOME, THE CONTACT ATTEMPTED TO ENGAGE THE SHIFTER INTO THE PARK POSITION; HOWEVER, THE VEHICLE SEIZED WITHOUT WARNING WHILE THE KEY WAS STUCK IN THE IGNITION. THE CONTACT ATTEMPTED TO DEPRESS THE SHIFTER LEVER AGAIN, BUT THE FAILURE RECURRED. THE CONTACT DID NOT ENGAGE THE EMERGENCY BRAKE. THE FOLLOWING DAY, THE CONTACT ATTEMPTED AGAIN TO PLACE THE SHIFTER IN THE PARK POSITION WITH THE KEY STILL IN THE IGNITION OVERNIGHT. THE CONTACT MANAGED TO GET THE GEAR TO SHIFT AND, ONCE RESTARTED, THE VEHICLE RESUMED NORMAL OPERATION. THE VEHICLE WAS TAKEN TO PAHRUMP VALLEY AUTO PLAZA (2060 E CHARLESTON PARK AVE, PAHRUMP, NV 89048, (775) 990-4402) WHERE IT WAS DIAGNOSED THAT THE SHIFTER LEVER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THE VIN WAS NOT INCLUDED IN A RECALL. THE FAILURE MILEAGE WAS APPROXIMATELY 60,000.

TL* THE CONTACT OWNS A 2014 BUICK REGAL. THE CONTACT STATED THAT THE VEHICLE HAD A SUDDEN LOSS OF POWER. THE CHECK ENGINE LIGHT FLASHES OFF AND ON. IDEAL BUICK GMC (5871 URBANA PIKE, FREDERICK, MD 21704, 301-663-3121) AND AN INDEPENDENT MECHANIC DIAGNOSED THAT CYLINDER FOUR WAS AT 75% PSI AND THE REST OF THE CYLINDERS WERE AT 160 PSI. THE DEALER AND THE INDEPENDENT MECHANIC WERE UNABLE TO PROVIDE A SPECIFIC REMEDY TO PREVENT THE LOSS OF POWER. THE VEHICLE HAD TO BE TOWED MORE THAN ONCE TO THE DEALER AND THE INDEPENDENT MECHANIC, BUT NO REMEDY WAS PROVIDED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES AND INDICATED THAT THERE WAS A POWER TRAIN WARRANTY THAT MAY COVER THE REPAIR. THE MANUFACTURER STATED THAT THEY WOULD FOLLOW UP REGARDING THE REPAIR PROCESS. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 42,225. *TR

OFF AND ON OVER THE PAST 6 MONTHS, THERE WAS A LOSS OF BRAKES DIRECTLY AFTER STARTUP. AFTER 30 SECONDS OR SO, THE BRAKES WOULD FUNCTION NORMALLY. THIS CAR IS NORMALLY GARAGE KEPT. WALKING TO THE CAR AT NIGHT TO LEAVE, I NOTICED OIL ON THE GARAGE FLOOR COMING FROM UNDER THE CAR. AFTER OPENING THE HOOD, I NOTICED OIL IN THE ENGINE COMPARTMENT COMING FROM THE TOP OF THE ENGINE. AFTER REMOVING THE PLASTIC ENGINE COVER, I SAW THAT THE OIL WAS COMING FROM WHAT I LEARNED IS THE VACCUM PUMP. THERE WAS A VISIBLE BREAK IN THE PUMP HOUSING. I WENT TO MY LOCAL DEALERSHIP TO INQUIRE ABOUT GETTING THIS SERVICED UNDER WARRANTY. THEY STARTED THAT THIS PART IS ONLY COVERED UNDER THE BUMPER TO BUMPER WARRANTY AND NOT POWERTRAIN WARRANTY, EVEN THOUGH THE VACUUM PUMP IS DIRECTLY MOUNTED TO AND CONNECTED TO THE INTAKE CAMSHAFT. MY BUMPER TO BUMPER WARRANTY HAD EXPIRED 3 1/2 MONTHS OR 219 MILES PRIOR, YET THE CAR IS STILL UNDER THE POWERTRAIN WARRANTY. THE DEALERSHIP WAS UNWILLING TO HELP AND QUOTED ME $104 FOR A NEW AC DELCO VACUUM PUMP. I WAS ABLE TO ORDER A NEW AC DELCO VACUUM PUMP FROM ROCK AUTO FOR $43. AFTER RECEIVING THE NEW PUMP, A MECHANIC FRIEND WAS HELPING ME TO REPLACE THE PUMP. WHEN THE OLD ONE WAS REMOVED, IT WAS SHOWN TO HAVE DISINTEGRATED. THE INSIDE OF THE PART WAS IN MANY PIECES. THE PART THAT ENGAGES THE CAMSHAFT WAS ALSO BROKE INTO PIECES AND AT THIS POINT I BELIEVE THAT SEVERAL OF THOSE ARE NOW INSIDE THE ENGINE. AT THIS POINT I AM GOING TO TAKE THE OLD PART TO THE DEALERSHIP, ALONG WITH PHOTOS OF THE ENGINE AND DEMAND THAT THIS IS NOW FIXED UNDER THE POWERTRAIN WARRANTY, AS THE POWERTRAIN IS DIRECTLY AFFECTED. HAD THIS HAPPENED WHILE DRIVING, THE LOSS OF BRAKES COULD HAVE BEEN CATASTROPHIC.
