WHENEVER I AM DRIVING MY VEHICLE FOR AN HOUR IT STARTS TO STALL OR SPUTTER IN TRAFFIC AND THE ENGINE DIES COMPLETELY. IT WILL RESTART BUT STILL CONTINUES TO HESITATE WHEN ACCELERATING. I'VE TAKEN IT TO A MECHANIC AND NO ERROR CODES POP UP WHEN THIS HAPPENS SO THEY DO NOT KNOW THE CAUSE OR HOW TO FIX THE ISSUE.

BACK ON FEBRUARY 9TH, 2019 I HAD AN OIL CHANGE AND RECEIVED WHATEVER PREMIUM-ULTRA SYNTHETIC OIL THEY HAD. THIS OIL WAS RATED UP TO 9,000 MILES I BELIEVE. AS I WAS HEADING IN FOR AN OIL CHANGE ON THE MORNING OF JUNE 2ND, 2019 THE CAR SUDDENLY LOCKED WITH BRAKES AND STEERING BECOMING EXTREMELY STIFF. I WAS DRIVING WHEN THIS OCCURRED BUT HAD BEEN COMING TO A STOP WITH NOBODY IN FRONT OF ME LUCKILY. HAD THIS HAPPENED 15 SECONDS BEFORE AS I WAS GOING 55MPH AROUND A CURVE, I WOULD HAVE UNDOUBTEDLY KILLED MYSELF OR SOMEONE ELSE. THERE WAS NO ABILITY TO STEER THE CAR OR BRAKE. WHEN I TOOK THE CAR TO THE DEALERSHIP THEY TOLD ME THE ENGINE WOULD REQUIRE A COMPLETE REBUILD, COSTING SEVEN-THOUSAND-DOLLARS. THEY CLAIM IT WAS CAUSED BY A "LACK OF MAINTENANCE (IE. NOT KEEPING UP ON OIL CHANGES)". THE LACK OF OIL THEN CAUSED THE TIMING CHAIN TO BREAK, WHICH THEN FURTHER DAMAGED INTAKE VALVES, HEAD GASKETS, BALANCE CHAIN, ETC. NOW I KNOW FEBRUARY 9TH AND JUNE 2ND IS NEARLY FOUR MONTHS APART, HOWEVER, IN THAT TIME I HAD PUT LESS THAN 2,000 MILES ON THE CAR. HOW WAS I SUPPOSED TO KNOW THAT MY ULTRA SYNTHETIC OIL WHICH IS RATED FOR FOUR TIMES LONGER, IN A CAR THAT IN THAT TIME HAD BEEN REPORTED TO BURN OIL, AND DOESN'T HAVE AN OIL LEVEL SENSOR, WOULD BURN OIL? IN MY MIND THIS ISN'T A LACK OF MAINTENANCE, IT IS GM'S LACK OF COMMUNICATION. GM NEVER INFORMED ME OF ANY ISSUES REGARDING OIL BURN, YET THEY SUPPOSEDLY REQUIRE TECHNICIANS TO ROLL BACK THE SENSOR BECAUSE OF THIS VERY ISSUE. I SHOULD ALSO MENTION THAT MIRACULOUSLY THE CAR WASN'T GIVING ANY OUTWARD SIGNS OF DISTRESS INCLUDING EXTRA NOISE, LOUD IDLE, HANDLING DIFFERENCES OR ANYTHING. WHILE MY SITUATION ENDED WITH NO INJURIES, AFTER READING ABOUT THIS ISSUE I AM ONE OF THE LUCKY ONES. THIS ISSUE IS NOT ONLY UNJUSTLY DRAINING BANK ACCOUNTS BUT ALSO COSTING LIVES.

HAD TO REPLACE ENGINE BECAUSE OF DETERGENT IN RECOMMENDED ENGINE OIL. WITH THE YEARLY OIL CHANGE AND HIGH DETERGENT LEVELS IT EATS AWAY AT SEALS AND GASKET.

THE CAR WAS VERY NOISY AT START UP. HAD THE OIL CHANGED, THE NOISE WAS BETTER FOR A WHILE BUT CAME BACK IN LESS THAN 2 MONTHS AND NOW IT IS CONSTANT. THE CAR WILL STALL OUT IN THE MIDDLE OF DRIVING. I WILL LOSE EVERYTHING, ELECTRICAL AND POWER STEERING. THIS WOULD HAPPEN WHETHER OR NOT ON A HIGHWAY OR DURING CITY DRIVING. ENGINE LIGHT CAME ON AND I TOOK IT TO MY MECHANIC. MECHANIC TOLD ME IT WAS IN REDUCE POWER MODE. CAMSHAFT CORALATION CODE.

NHTSA ODI 11197025

TIMING CHAIN TENSIONER FAILED AT JUST LESS THAN 75,000 MILES. I'VE BEEN TOLD BY 2 DIFFERENT MECHANICS THAT IT WOULD BE EASIER TO REPLACE THE ENTIRE ENGINE THAN GET THE PIECES OUT OF THE ENGINE.

NYB CAR HAS LESS THAN 69K MILES AND IS BURNING THROUGH OIL. I BOUGHT IT USED AND THE DEALER LIKED WARRANTY ENDED BEFORE PROBLEMS STARTED. MY CHECK ENGINE LIGHT CAME ON WITHIN THE FIRST 2000 MILES OF ME DRIVING AND THE DEALER WANTED TO CHARGE ME ANOTHER $200 FOR A DIAGNOSTIC. SO I WENT TO A MECHANIC AND HE SAID THE ENGINE WAS BURNING THROUGH OIL FASTER THAN IT SHOULD. AT THIS POINT THE CAR HAD TURNED OFF WHILE UNDER 10MPH TWICE WHICH IS DANGEROUS AS THE BRAKES LOCK UP ALONG WITH STEERING BECOMING VERY STIFF. A MECHANIC DID WORK ON THE CAR REPLACING PLUGS AND OTHER PARTS THAT HAD BEEN DAMAGED FUE TO THE OIL BEING GONE, BUT THE SAME ENGINE IS STILL IN THE CAR. NOW LESS THAN A YEAR LATER ALONG WITH REGULAR OIL CHANGES THE CAR STILL BURNS THROUGH OIL. THE ENGINE CAUSES THE CAR TO ROCK WHEN AT IDLE AND WHEN MOVING UNDER 5MPH. MY FEAR IS THAT IVE CAR WILL SHUT OFF AGAIN. THIS IS A FAULT OF BUICK FOR DESIGNING AN ENGINE THAT CAN'T HOLD OIL.

ENGINE OF MY CAR ACTS WEIRD AND I TOOK IT TO THE MECHANIC SHOP AND THEY SAY THERES NOTHING WRONG

WE WERE IN A NO CELL SERVICE AREA AND HAD TO DRIVE IN THE SHOULDER NOW THE HEADLIGHTS WON'T TURN ON AT ALL EITHER. THE CAR NEVER ALERT US IT JUST SHUT OFF THE DEALER SAYS THE OIL WAS VERY LOW AGAIN NO OIL LIGHT CAME ON WITH THAT YHE DEALER SAYS THERECOULD BE A BCM/ECM COMMUNICATION ISSUE COSTING 1200.00 TO 2500.00 TO FIX. THEY CAN'T ASSESS COMPLETELY UNTIL THE PISTON/ TIMING BELT ISSUE IS FIXED BUT THE CAR IS NOT COMMUNICATING THE STEERING IS NOW SUPER TIGHT AND THE ONLY YHING IT SAYS NOW IS SERVICE STIBILATRAC AND THE MECHANIC DIDN'T EVEN BRING THAT UP

WHEN CHECK ONLINE, LOTS OF PEOPLE HAVE COMPLAINED ABOUT THE SAME PROBLEM AND HOW DIFFICULT FOR IT TO BE RESOLVE AS MANY THINGS BROCKEN CAN CAUSE THE PROBLEMS.

THE THROTTLE BODY HAS A DEFECT WHICH SHUTS OFF ALL POWER TO VEHICLE WITH NO NOTICE. THE ENGINE AND TRANSMISSION LOCK UP YOU LOSE ALL STEERING CONTROL AND NO BRAKES. ALSO NO LIGHTS SO WHEN IT HAPPENS AT NIGHT IT IS PITCH BLACK. GM DOES KNOW ABOUT THE PROBLEM AND WHEN I QUESTIONED THEM ABOUT THE LOSS OF LIFE LIKE WHAT HAPPEND WITH THE CHEVY CRUZE ALL MEMBERS OF GM ARE TOLD TO HANG UP THE PHONE. IT HAS HAPPEND ON SEVERAL OCCASIONS AND THE DEALERSHIP SENT ME BACK ON THE ROAD KNOWING THE PROBLEM. DEALER REP SAID IF I WAS A BETTER CUSTOMER THAY MAY HAVE DONE MORE FOR ME.
