2015 Chevrolet Corvette Complaint Log

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.

JUST AS YOU ACCELERATE, AROUND 1200 TO 1500 RPM, WITH A LIGHT TOUCH, YOU HEAR WANT IS BEING DESCRIBED AS A "WARBLE" SOUND. IT HAS A METALLIC RING AND LASTS A FEW SECONDS. LOADING THE ENGINE ON A HILL MAKES THE SOUND MORE INTENSE. IT IS HAPPENING TO A STOCK 2015 STINGRAY COUPE. THOUGHT THIS WAS ONLY HAPPENING TO ME BECAUSE OTHERS DO NO HAVE THIS ISSUE BUT FOUND A GROUP OF CORVETTE OWNERS ON THE CORVETTE FORUM WITH THE SAME ISSUE.

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.

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 VARIOUS SPEEDS, THE REARVIEW MIRROR DISPLAYED A BRIGHT BLINDING LIGHT THAT OBSTRUCTED THE DRIVER'S VIEW. IN ADDITION, THE LIGHT CAUSED A REFLECTION ON THE WINDOWS OF THE VEHICLE AND THE CONTACT COULD NOT SEE OUT OF THEM. ORR CHEVROLET IN FORT SMITH, ARKANSAS WAS MADE AWARE OF THE FAILURE AND STATED THAT THE CONTACT SHOULD PLACE A PIECE OF TAPE OVER THE LIGHT SENSOR. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT ENOUGH PEOPLE HAD NOT COMPLAINED ABOUT THE FAILURE FOR IT TO BE A RECALL. THE FAILURE MILEAGE WAS APPROXIMATELY 12,000.

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.

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

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.

The contact owns a 2015 Chevrolet Corvette. The contact stated while driving 60 MPH, the vehicle started to overheat. The contact pulled over and turned off the vehicle to allow the vehicle to cool down. The vehicle was able to cool down and then operated normally. The vehicle was taken to the dealer and the contact was informed that the radiator needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and the contact was informed that the vehicle was not under recall. The contact was referred to the NHTSA for assistance. The failure mileage was 12,000.

WATER LEAKING INTO REAR CARGO HOLD AREA. ACCUMULATING AND NOT DRAINING OUT. DON'T KNOW WHY.

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.

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.

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
