What 64 owners told NHTSA about the 2015 Chevrolet Corvette

I RAN OUT OF GAS ON THE INTERSTATE DURING RUSH WITH A TRACTOR TRAILER BEHIND ME? HOW I GOT TO THE SHOULDER WAS A MIRACLE!! THEN I NOTICED THE ENGINE WARNING LIGHT CAME ON, THE GAS GAUGE STOPPED WORKING? THE ROAD WARRIOR CAME AND GAVE ME SOME GAS. I TOOK IT MY DEALER RIGHT AWAY. THEY GAVE ME A LOANER. AFTER A FEW DAYS I CALLED FOR AN UPDATE? THE SERVICE DEPTARTMENT TOLD ME IT WAS THE FUEL SENDER UNIT THAT WENT BAD. AND THAT PART IS ON NATIONAL BACK ORDER?? I DON'T KNOW WHAT THAT MEANT? SO I CALL GM'S CUSTOMER RELATIONS AND SPEAK TO A GLORIA. SHE INFORMS ME THE PART IS UNAVAILABLE. AND SHE DOES NOT HAVE AN ETA ON IT?? I TOLD HER I THOUGHT THAT CAR COMPANIES ARE SUPPOSE TO KEEP PARTS FOR NEW MODEL CAR FOR AT LEAST THROUGH THE WARRANTY PERIOD? SHE AGREED!! IMAGINE? SO I ASK THEN WHY IS MY PART? SHE COULDN'T ANSWER? I BOUGHT MY CAR IN MARCH, 2015 AND HAVE 7180 MILES ON HER. AND IS OBVIOUSLY STILL UNDER WARRANTY! I BRING IT BACK TO MY DEALER AND TELL HIM I WANT A NEW CAR BECAUSE BY THIS TIME IT'S BEEN 30 DAYS WAITING FOR PART. I AM DRIVING WITH THE TRIP MONITOR, TO TRY GAUGE GAS USAGE?

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 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.

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.

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.

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.

CHEVY IS SELLING 2015 Z-51 CORVETTES WITH SUMMER ONLY RUN-FLAT TIRES. MICHELIN INDICATES THAT THESE TIRES SEVERELY LOSE TRACTION WHENEVER TEMPERATURES FALL BELOW 40 DEGREES F. THEY ARE ALSO NOT APPROPRIATE FOR USE IN WET OR SNOWY CONDITIONS. MICHELIN OR ANY OTHER TIRE MANUFACTURER DOES NOT MAKE AN ALL-SEASON TIRE THAT IS A RUN-FLAT. OWNERS WHO ARE NOT AWARE OF THIS CONSTRAINT OR THOSE WHO IGNORE THE PROBLEM ARE AT RISK FOR A SERIOUS ACCIDENT AND INJURY. CHEVY IGNORES THE PROBLEM AND OFFERS NO SOLUTION. OTHER MANUFACTURERS SUCH AS BMW ALSO USE SIMILAR SIZE TIRES WHICH DO NOT HAVE SUITABLE ALL-SEASON RUN FLAT REPLACEMENTS. THOUSANDS OF THESE CARS ON THE ROAD PRESENT SERIOUS RISKS FOR EVERY DRIVING ALONG SIDE THESE VEHICLES. PEOPLE WHO BUY USED CARS WITH THESE SUMMER ONLY TIRES MAY NOT HAVE ANY IDEA THAT THEY SUMMER ONLY TIRES NOR THE RISK THEY MAY BE TAKING. I AM SURE THERE ARE NO RECORDS OF HOW MANY ACCIDENT HAVE BEEN CAUSED BY THESE TIRES SINCE NO ONE HAS PROBABLY TAKEN NOTICE OF THE TIRE TYPES ENVOLVED IN ACCIDENTS.

AT ANY SPEED THE CAR JERKS LIKE ONE OR MORE SPARK PLUG WIRES ARE NOT FIRING(PULLED OFF) IN ALL MODES, IT IS WORSE IN (E ECONOMY MODE) PUSH THE GAS DOWN IT GETS WORSE IN ALL MODES. I REPLACED THE PLUGS AND WIRES I STILL HAVE THIS PROBLEM, I WAS HOPING IT WAS A BAD PLUG OR WIRE, THAT HAPPENS. I TOOK IT TO THE DEALER WHEN THE CHECK ENGINE LIGHT CAME ON I PULLED THE FUSE FOR THE EXHAUST VALVES TO KEEP THEM OPEN THEY CHECKED THEN TESTED THE CAR AND TOLD ME IT WAS FINE NO OTHER CODES WERE FOUND. I HAVE 1800 MILES ON THE CAR NOW I TRIED EVERY 93 OCTANE FUEL AVAILABLE IN THIS AREA AND OTHER AREAS, HOPING IT WAS JUST BAD FUEL THAT MANY STATIONS CAN'T HAVE BAD FUEL FOR IT TO BE FUEL RELATED. *TR
