2014 Buick Regal Powertrain & Transmission Problems

Problem in translation

2014 Buick Regal GS AWD sedan, second owner. Car was purchased as a certified used from Buick dealer in 2018 with 40,xxx miles. Car now has 137,xxx miles, no longer under extended warranty. Have had all regular maintenance done and have records. Aside from normal wear and tear, no prior issues with car. Car engine suddenly started to run rough, Check Engine light came on while driving 65 mph, sudden loss of engine power and car died on the highway causing congestion and vehicles to swerve on highway, loss of steering control, pulled over. Car was able to be restarted but running rough, engine light on, severe reduction in power. Talked with nearest dealer, they said to not drive car. Had local GM mechanic do inspection, computer codes indicated loss of compression on cylinder 3, misfire. Compression check and bore inspection indicated loss of compression on cylinder 3, valve failure/damage, oil in the turbo, requiring complete rebuild or replacement engine and turbo. Review of TSB from GM indicated this is a known issue, engine to be replaced.

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.
