2014 Buick Regal

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.

After buying car from Car dealer named Carizona in Mesa Arizona. 1 week later car needs new engine. Initially message appeared stating Engine Performance reduced after leaving the car dealer. How is it that a car dealer purchases a car not ensuring safety of its vehicles. Was there even a safety check. What if I or someone else got hurt after driving that vehicle. There are multiple safety reports but they are still selling cars.

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.

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.
