2014 Buick Regal Complaints

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 MIS...

THE POWER STEERING HAS STOPPED WORKING. I HAD TO REPLACE THE BATTERY ON THE CAR. AFTER I REPLACED THE BATTERY, THE POWER STEERING HAD STOPPED WORKING. THE VEHICLE WAS STATIONARY.

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.
