2015 CHEVROLET CORVETTE Complaints

TL* THE CONTACT OWNS A 2015 CHEVROLET CORVETTE. THE CONTACT STATED THAT WHILE DRIVING AT 65 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT WAS UNABLE TO RESTART THE VEHICLE. THE CONTACT MENTIONED THAT THE VEHICLE WAS OUT OF FUEL BUT THE FUEL GAUGE INDICATED THAT THE VEHICLE WAS NOT LOW OF FUEL. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE FUEL GAUGE SENDING UNIT NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED DUE TO THE PART NOT BEING AVAILABLE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 7,168.

AUTOMATIC A8 TRANSMISSION HAS THE FOLLOWING ISSUES: 1)MORNING SHIFT FROM REVERSE TO DRIVE SEVERELY DELAYED, BANGS IN EVENTUALLY. 2) ERRATIC SHIFTING IN NORMAL TRAFFIC 3) THE 2-1 DOWNSHIFT WHEN COMING TO A STOP RESULTS IN SEVERE BANG, LURCHES FORWARD AND IS VERY UNSAFE IN A PARKING LOT SITUATION. ALSO IN STOP AND GO TRAFFIC, SAME LURCHING FORWARD. FEELS AS IF SOMEONE HIT YOU FROM BEHIND 4) TORQUE CONVERTER LOCKUP IN 5TH AND 6TH GEAR. DEALER TORE APART THE CAR TO REPLACE THE STATOR, PERFORMED SOFTWARE UPDATE - NEITHER SOLUTION WORKED.

THE A8 AUTOMATIC TRANSMISSION IN THE 2015 CORVETTE IS PRONE TO OCCASIONAL HARD DOWNSHIFTS FROM 2ND TO 1ST GEAR WHEN DRIVING AT SLOW SPEEDS (LESS THAN 10 MPH). SOMETIMES THE DOWNSHIFTS ARE SO VIOLENT THAT THE CAR JERKS FORWARD SEVERAL FEET. THE FIRST TIME IT HAPPENED I THOUGHT I HAD BEEN REAR ENDED BY ANOTHER CAR. THE UNPREDICTABLE BEHAVIOR OF THE TRANSMISSION IS ESPECIALLY DANGEROUS IN PROXIMITY TO PEDESTRIANS OR OTHER VEHICLES.

AUTOMATIC 8 SPEED TRANSMISSION HAD TO BE REPLACED AT 2000 MILES ON THE ODOMETER DUE TO HARD SHIFTS AND SHIFTING AUTOMATICALLY TO LOW GEAR AT HIGHWAY SPEEDS NEARLY BRINGING THE CAR TO A STOP IN INTERSTATE TRAFFIC, NOW 700 MILES AND 4 MONTHS LATER THE TRANSMISSION IS STUCK IN SECOND GEAR AND YOU CANT DRIVE FAST ENOUGH TO GET OUT OF THE WAY OF TRAFFIC. AND I KNOW OF SEVERAL OTHER CARS LIKE IT THAT HAVE SIMILAR PROBLEMS. THIS IS A REAL SAFETY PROBLEM AND GM SEEMS TO IGNORE IT, PROBABLY UNTIL SOMEONE GETS HURT OR KILLED.

8-SPEED AUTOMATIC TRANSMISSION ALWAYS SHIFTS ERRATICALLY WHEN STARTING OUT COLD (LAZY SHIFT, SLOW SHIFT, ETC.) AND OCCASIONALLY DOES NOT DOWNSHIFT WHEN CAR COMES TO A STOP, ONLY TO SLAM HARD INTO 1ST WHEN GAS PEDAL IS PRESSED TO RESUME TRAVEL. DEALER SAYS GM CLAIMS THIS IS "NORMAL," BUT NO CAR I'VE EVER OWNED BEHAVES LIKE THIS. APPEARS TO BE FLUID STARVATION INTERNALLY. ANY FIX/REPLACEMENT WOULD BE COSTLY FOR GM, SO GIVEN THEIR HISTORY W/FAULTY IGNITION SWITCHES, NOT SURPRISED THEY'RE TRYING TO AVOID IT. TRANSMISSION IS DEFINITELY NOT NORMAL AND BEHAVIOR IS UNPREDICTABLE + UNACCEPTABLE -- ESPECIALLY AT THIS PRICE. WHEN CAR IS MOVING & TRANSMISSION IS IN DRIVE AND TRYING TO LAZILY SHIFT GEARS, YOU TEMPORARILY LOSE ABILITY TO APPLY POWER, WHICH IS BOTH DANGEROUS AND UNNERVING. CLEARLY, THIS TRANSMISSION WAS PUT INTO PRODUCTION W/INADEQUATE TESTING & DEVELOPMENT. A RECALL IS NECESSARY TO FIX PROPERLY.

CAR WAS BEING FILED WITH GAS AT STATION, I WAS 25 FT AWAY WITH MY KEYS AND THE ENGINE STARTED BY ITSELF. NO ONE IN CAR, NOT NEAR CAR, KEYS IN MY JACKET POCKET. CAR WAS NOT IN MOTION AND ENGINE WAS OFF WHILE PUMPING GAS.

TL* THE CONTACT OWNS A 2015 CHEVROLET CORVETTE. WHILE DRIVING 40 MPH, THE INSTRUMENT PANEL DIMMED. THE CONTACT COULD NOT SEE ANY OF THE INDICATORS, INCLUDING THE SPEEDOMETER. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE INSTRUMENT PANEL SCREEN NEEDED TO BE REPLACED. THE REPAIRS WERE PERFORMED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 1,500. UPDATED 01/07/16*LJ *TR

8 SPEED AUTOMATIC TRANSMISSION DOWN SHIFTS AT A STOP WITH SUCH FORCE IT FEELS AS YOU HAVE BEEN HIT FROM BEHIND BY ANOTHER CAR WHILE COMING TO A STOP. TRANSMISSION ALSO WILL NOT ALWAYS ENGAGE PROPERLY AND WILL OVER REV AND SLAM INTO GEAR POSSIBLY CAUSING AN ACCIDENT. TRANSMISSION AT TIMES WILL DISENGAGE WHILE GOING FORWARD THEN SLAM INTO GEAR WITH GREAT FORCE. I WAS TOLD BY A GM INSIDER THAT GM IS AWARE SOME TRANSMISSIONS ARE DEFECTIVE AND IS WORKING ON A KIT TO FIX THE FLUID STARVATION PROBLEM INTERNALLY BUT HAS DONE NOTHING TO INFORM OWNERS OF THE POTENTIAL DANGERS OF ERRATIC SHIFTING THAT IT'S CAUSING WHILE DRIVING. THIS ALSO CAUSES THE TRANSMISSION TO OVER HEAT AND TO ILLUMINATE A WARNING LAMP.

SHIFTER STICKS IN PARK INTERMITTENTLY. DEFECTIVE SOLENOID ON SHIFTER THAT CAN NOT BE REPLACED. NEED TO REPLACE ENTIRE SHIFTING UNIT TO REPAIR. DEFECTIVE SOLENOID ON NEW SHIFTERS FAIL ALSO. $700 TO $1000 TO REPAIR. ONLY HAS 10,000 MILES ON CAR.

FOLLOWING THE OWNER?S MANUAL INSTRUCTION TO BURNISH THE BREAKS, I TOOK MY CAR TO AN AREA WHERE I COULD GO FROM ZERO TO 60 MPH THEN BREAK, 50 TIMES IN 10 MINUTES. ON ABOUT THE 40TH CYCLE, THE ENGINE OVERHEATED AND STARTED TO ?REV LIMIT? AND A WARNING CAME ON THAT SAID TO CHANGE THE ENGINE OIL, WHICH I JUST HAD DONE. THE FINAL TEN CYCLES TOOK A LOT LONGER TO GET TO 60. THE HVAC SYSTEM WAS OFF DURING THE PROCEDURE, THE TEMP OF THE COOLANT GOT CLOSE TO 320F, AND THE OUTSIDE TEMPERATURE SAID 103F. AFTER THE 50TH RUN I DROVE THE CAR AT ABOUT 60 MPH UNTIL THE ENGINE GOT TO A SAFE TEMPERATURE THAN I TURNED ON THE AIR AND GOT THE SAME TOXIC ODOR I EXPERIENCED WHEN I FIRST TOOK DELIVERY. IT MADE ME SICK TO MY STOMACH AND I HAD TO OPEN THE WINDOWS. I HAD GONE THROUGH GREAT LENGTHS TO GET RID OF THAT ODOR AND THOUGHT IT WAS AT AN ACCEPTABLE LEVEL BEFORE THE BURNISHING. I ALWAYS LEFT THE WINDOWS OPEN WHEN PARKED IN MY GARAGE, I PUT THE CAR IN THE DIRECT SUN FOR SEVERAL DAYS WITH DOORS AND BACK OPEN, AND THE TOP OFF, AND EVEN LEFT THE ENGINE RUNNING FOR SIX HOURS ONE DAY WITH THE AIR ON. I HAD ALSO DRIVEN THE CAR WITH THE WINDOWS OPEN FOR TWO HOURS WITH THE HEATER AT MAX TEMP. THE ODOR WAS OF SUCH A CONCERN THAT TWO DOCTORS SUGGESTED I SELL THE CAR. HERE IN CALIFORNIA 115F DEGREES OR MORE IS NOT UNCOMMON, AND OFTEN MUCH HIGHER ON BLACK PAVEMENT. I AM CONCERNED THAT I DON?T KNOW WHEN THE CAR MIGHT OVERHEAT AGAIN AND PRODUCE MORE TOXIC FUMES. I HAVE TAKEN THE CAR TO THE DEALER AND THE FACTORY REPRESENTATIVE IGNORED THE HEATING PROBLEM AND SAID HE COULD NOT SMELL ANYTHING OTHER THAN THE NEW CAR SMELL. THEY DID CHANGE THE OIL FREE OF CHARGE AND GIVE ME A ?2015 CORVETTE TRACK PREPARATION? FLYER THAT SPECIFIED DIFFERENT VISCOSITY OIL AND A DIFFERENT BURNISHING PROCEDURE. UNFORTUNATELY THERE WAS NO DATE OR NUMBER ON THAT FLYER.
