2014 Chevrolet Malibu

The contact owns a 2014 Chevrolet Malibu. The contact stated that when she started the vehicle, the vehicle was in manual mode while the vehicle was parked. The vehicle failed to shift into gear as needed. An independent mechanic diagnosed the vehicle and replaced the battery; however, the failure persisted. The dealer was contacted, and the contact explained that her vehicle had experienced the failure listed in NHTSA Campaign Number: 14V092000 (Power Train). The dealer confirmed that the VIN was not included in the recall and informed her that she was responsible for the cost of the repair. The manufacturer was contacted, and they also stated that the vehicle was not under recall and advised to contact the NHTSA. The failure mileage was 214,000.

My car is throwing a rocker arm valve code but chevy is saying its not covered under the NHTSA program that was passed. Its a 2014 chevy malibu 2.5 L with 93000 miles on it. It causes the auto stop to malfunction and the car will completely shut down when stopped. It will not restart at all. Have been almost hit 3 times at major intersections.

THIS HAS HAPPENED TWICE NOW, ONCE FOR MY WIFE AND THE SECOND TIME I WAS DRIVING. BOTH INCIDENTS HAPPENED WHILE IN MOTION ON THE HIGHWAY AND THE VEHICLE DISPLAY SHOWED REDUCED ENGINE POWER AND THE VEHICLE DE-RATED AND SLOWED AUTOMATICALLY ON THE HIGHWAY. THE CHECK ENGINE LIGHT DISPLAYED AND AFTER CONNECTING A CODE READER TO THE OBD AND CODE P2138 WAS LOGGED WHICH IS POTENTIALLY A FAULTY THROTTLE POSITION SENSOR/ FOOT GAS PEDAL. I REPLACED THE THROTTLE POSITION SENSOR CLEARED THE STORED CODE AND A COUPLE WEEKS LATER THE VEHICLE AGAIN WENT INTO LIMP MODE AND DE-RATED ON HIGHWAY. THE CHECK ENGINE LIGHT CAME ON AND THE SAME CODE P2138 WAS LOGGED INDICATING VOLTAGE DIFFERENCE BETWEEN APP SENSOR 1 AND APP SENSOR 2 OF THE THROTTLE POSITIONING SENSOR. AFTER FURTHER RESEARCH ON LINE I FOUND THAT A GM SERVICE BULLETIN WAS ISSUED FOR POTENTIAL MOISTURE INTRUSION OF THE CONNECTORS FROM THE THROTTLE POSITION SENSOR TO THE ECM. (SEE ATTACHED) IT SEEMS LIKE MY VEHICLE IS EXPERIENCING MOISTURE IN THE CONNECTORS AS BOTH INCIDENTS HAPPENED WITHIN MINUTES OF TAKING THE VEHICLE THROUGH AN AUTOMATIC CAR WASH. IN MY OPINION THIS IS A SAFETY CONCERN FOR THIS MODEL VEHICLE TO DE-RATE AND SLOW DOWN SUDDENLY AT HIGHWAY SPEEDS WITH CARS FOLLOWING BEHIND AND HAS BEEN A KNOWN ISSUE BY GM AND SHOULD HAVE A RECALL ISSUED.

DRIVING DOWN FREEWAY ABOUT 70 MPH WHEN ALL OF A SUDDEN I HEAR A CHIME THEN ENGINE SEEMS TO DOWNSHIFT BUT IT ACTUALLY REDUCED SPEED QUICKLY. I LOOK UP AT DASH AND SEE THAT IT SAYS, 'ENGINE POWER IS REDUCED'. I THEN NOTICE TO THE LEFT OF DASH THAT THE ENGINE PIC IS LIT UP. I PUT MY HAZARD LIGHTS ON AND EXIT THE FREEWAY RIGHT AWAY. WHAT I WOULD NORMALLY DO IS OPEN UP THE OWNERS MANUEL AND FIND OUT A LITTLE MORE TO WHAT'S GOING ON. I JUST PURCHASED THE CAR AND IT DIDN'T COME WITH ONE. I DECIDED TO TAKE SIDE STREETS THE REST OF WAY HOME. WHEN I GOT HOME I SHUT CAR OFF THEN STARTED IT UP AGAIN AND IT STILL HAD THE SAME MESSAGE.

ON 7/5/20 THE VEHICLE WAS IN MOTION GOING DOWN THE HIGHWAY AND THE HIGH PRESSURE FUEL PUMP MOUNTED ON THE ENGINE BROKE LOSE, DROPPED INTO THE ENGINE AND TORE APART THE ENGINE. WAS TOWED AND FIXED BY CLOSEST GM DEALERSHIP (DEERY BROTHERS, WEST BURLINGTON, IA). THERE IS A RECALL FOR A BAD WELD ON THE HIGH PRESSURE FUEL PUMP FOR 2016-2018 MALIBU'S RESULTING IN THE EXACT ISSUE I HAD ON MY 2014. THE DEALERSHIP SAID GM, CHEVROLET AND THE DEALERSHIP (WHICH IS A GM CERTIFIED DEALERSHIP WHERE I BOUGHT THE CAR CERTIFIED PRE-OWNED IN 2018) SAID THEY ALL BARED NO RESPONSIBILITY FOR THE ISSUE. I PAID $3,128 FOR THE REPAIR ON 7/17/20. TWO DAYS AFTER BRINGING MY CAR HOME, THERE IS AN OIL LEAK THAT WAS NEVER THERE BEFORE. THE DEALERSHIP SAYS THIS IS A HOLE IN THE OIL PAN, AND AGAIN IS MY RESPONSIBILITY TO PAY FOR IN FULL TO BE FIXED. I RECEIVED A LETTER FROM CHEVROLET ON 7/16/20 SAYING THERE IS A RECALL FOR MY VIN # FOR AN OIL PRESSURE VALVE. INCORRECT OIL PRESSURE COULD HAVE CAUSED THE HIGH PRESSURE FUEL PUMP TO EXPLODE CAUSING THE ISSUE ON 7/9/20. I DO NOT BELIEVE THAT BETWEEN THE TWO RECALLS ISSUED BY CHEVROLET FOR MY CAR MODEL I SHOULD BE RESPONSIBLE FOR THE FULL WEIGHT OF THE REPAIRS ON A CAR THAT WAS PURCHASED CERTIFIED PRE-OWNED WITH A WARRANTY TWO YEARS PRIOR, NOT TO MENTION I'VE HAD ALL REGULAR SERVICES DONE IN A TIMELY MATTER AT THE SAME DEALERSHIP, THAT HAS UNDER 90,000 MILES AND IS ONLY SIX YEARS OLD. THERE IS NO REASON FOR SUCH EXTENSIVE ENGINE DAMAGE TO SUCH A NEW CAR WITH NO PREVIOUS ISSUES.
