2015 CHEVROLET CORVETTE Complaints

A8 TRANSMISSION SHUDDER. HAD FLUID CHANGE AT 10305 MILES. AT 10881 MILES PROBLEM IS NOW WORSE THAN BEFORE. WARRANTY IS NOW EXPIRED . HOPEFULLY GM HAS A REMEDY FOR THIS PROBLEM ON 2015 CORVETTE. HAVE OWNED FIVE CORVETTE. THIS MAY BE THE LAST ONE GM NEEDS TO STAND BEHIND THEIR PRODUCT.

WHEN REFUELING, TANK FILLER PIPE ACCEPTS FUEL ONLY VERY SLOWLY. SEVERAL DIFFERENT GAS STATION PUMPS WERE TRIED, ALL KEPT CLICKING OFF EVERY 3 SECONDS (AS IF TANK WAS FULL). TANK EVENTUALLY TOOK AN ADDITIONAL 7 OR 8 GALLONS, BUT IT TOOK 8 OR 10 MINUTES TO ACCOMPLISH THAT.

TSB 18-NA-355 - VEHICLE IS EXPERIENCING A SHAKE AND/OR SHUDDER DURING LIGHT THROTTLE ACCELERATION BETWEEN 25 AND 80 MPH (40 AND 128 KM/H) STEADY STATE DRIVING WHEN TRANSMISSION IS NOT ACTIVELY SHIFTING GEARS. THE EXPERIENCE IS SIMILAR TO DRIVING OVER RUMBLE STRIPS OR A CONCRETE ROAD SURFACE WITH ROUGH EXPANSION JOINTS. TOOK TO DEALERSHIP TO REPAIR, BUT THEY ARE STATING THE WARRANTY ENDED IN JANUARY AND REQUIRING ME TO PAY FOR THE FIX. WILL JOIN THE CLASS ACTION LAWSUIT.

WHEEL RIM CRACK AT BEAD AND LEAKS AIR. IT A WIDELY KNOW ISSUE, AND I HAVE BECOME A STATISTIC. I HAVE READ THERE MAY BE A CLASS ACTION AGAINST GM FOR SUCH ISSUE.

THE VEHICLE IS EQUIPPED WITH AN 8L90 AUTOMATIC TRANSMISSION. IT HAS A SEVERE SHUDDER PROBLEM WHEN CRUISING DOWN THE ROAD AT 50 TO 70 MPH. CAN GET ALMOST UNDRIVABLE. ALSO WILL NOT UPSHIFT AFTER A PERFORMANCE DOWNSHIFT. DEALER FLUSHED TRANSMISSION PER GM BULLETIN BUT PROBLEM IS STILL THERE. LOOKS LIKE ALMOST ALL OF GM 8 SPEED TRANSMISSIONS HAVE THIS PROBLEM CIRCA 2015-2016.

EXPERIENCED THE EXACT SAME WEIRD CRACKED WHEEL THAT MANY OTHER C7 OWNERS HAVE EXPERIENCED ON 7/11/19. NO SPECIFIC POTHOLE. JUST CRACKED WHEEL WHICH LOOKS LIKE ALL THE OTHERS ON THE CORVETTE FORUM.

SEAT BELT PRETENSIONER ON THE PASSENGER SIDE DEPLOYED (SOUNDED LIKE A SHOTGUN BLAST IN THE CABIN) WITHOUT PROVOCATION. NO ACCIDENT, DID NOT RUN OVER ANYTHING, ETC. GOING STRAIGHT ~45MPH ON AN EMPTY STREET AT 12:50AM. SMOKE BILLOWING OUT OF THE CABIN OF MY CAR, ALL THE LIGHTS WERE ON, BELLS WERE RINGING, ETC. IT'S AS IF I WAS IN AN ACCIDENT, BUT NO AIRBAGS DEPLOYED. FRIGHTENING EXPERIENCE! GM SAID IT IS NOT THEIR PROBLEM.

BOTH OF MY OEM REAR WHEELS (SPECTRA GRAY - 10 SPOKE), HAVE DEVELOPED CRACKS REQUIRING REPLACEMENT AT MY EXPENSE. DESPITE MY CORVETTE BEING ON WARRANTY AND A HIGH PERFORMANCE, SPORTS CAR WHICH IS REGULARLY SERVICED, THE CHEVROLET DEALERSHIP REFUSES TO REPLACE THESE WHEELS, EXCEPT AT MY EXPENSE, CITING THAT POOR ROAD CONDITIONS IN CALIFORNIA ARE BLAME FOR THE FRACTURES, RUNNING HORIZONTALLY ON THE RIM LIP. THE FRACTURES CREATE A VERY DANGEROUS SITUATION GIVEN HIGH TORQUE LEVELS, LOW PROFILE TIRES WITH A WIDE STANCE. THE TIRES AND THE SUSPENSION ARE DESIGNED FOR HIGH PERFORMANCE, AND HIGH G FORCE, BUT WHEELS ARE APPARENTLY FLAWED FOR THE DESIGNED TOLERANCES IMPOSED BY DRIVING A HIGH PERFORMANCE CORVETTE. MY CAR RAPIDLY LOSS AIR PRESSURE AT FREEWAY SPEEDS AND THE AIR PRESSURE WARNING LIGHT ACTIVATED IN BOTH OCCASIONS, WARNING OF THE HAZARDOUS CONDITION.

I'VE ALMOST BEEN HIT TWICE PULLING INTO TRAFFIC ON A CITY STREET WITH THIS CAR. SHIFTING WHEN THE TRANSMISSION IS COLD INTO 2ND GEAR FROM 1ST GEAR IS NEAR IMPOSSIBLE AND APPEARS TO BE A KNOWN PROBLEM BASED ON MY INTERNET SEARCH. SEVERAL TIMES I'VE PULLED INTO TRAFFIC AND COULDN'T SHIFT IT INTO 2ND GEAR. BY THEN THE CAR IS SLOWING DOWN WITH TRAFFIC BEARING DOWN ON IT AND YOU HAVE TO SLOW DOWN EVEN MORE TO GO BACK TO 1ST GEAR. THE LOCAL DEALERSHIP SAYS THIS IS NORMAL BUT I DISAGREE BECAUSE IT'S A SAFETY ISSUE. I HAVE TO REV THE ENGINE HIGHER AND GO DIRECTLY INTO THIRD GEAR TO PROTECT MY LIFE.

WHEN I TOOK THE CAR INTO A DISCOUNT TIRE STORE TO HAVE NEW TIRES PUT ON THE BACK AT ABOUT 15,600 MILES ON THE CAR CRACKS WERE FOUND ON THE INSIDE RIM WHERE TIRE BEAD SEALS OF BOTH BACK WHEELS. PROBLEM WAS IMMEDIATELY REPORTED TO DEALER WHO VERIFIED CRACKS, BUT DEALER AND GM REFUSED TO REPLACE UNLESS I PURCHASE NEW WHEELS FOR DISCOUNTED PRICE OF $1,100.00 FOR REAR WHEELS ONLY. SPOKE WITH REPRESENTATIVES OF GM ENGINEERING AND FOUND PROBLEM IS A KNOWN ISSUE WITH REAR WHEEL CRACKING GOING BACK SEVERAL YEARS WITH CAST CHINA MADE WHEELS ON CORVETTE Z06 AND ZR1 MODELS. I WAS TOLD GM CORVETTE CHIEF ENGINEER HAS POSTED INFORMATION ON THE WHEEL CRACKING PROBLEM ON CORVETTE FORUM AND ONLY WAY TO NOT HAVE WHEEL CRACKING PROBLEM ON REPLACEMENT WHEELS WOULD BE TO NOT DRIVE ON ROADS WITH BUMPS OR POT HOLES. THEY AGREED THIS WAS NOT REALISTIC BUT GM STANDS FIRM ON PAYMENT FOR NEW WHEELS WITH NO ASSURANCE THIS WILL SOLVE THE PROBLEM. MY COMPLAINT WAS CLOSED AT GM AS CUSTOMER DECLINED REDUCED PRICE OFFER AND IS DISSATISFIED. CRACKING WHEELS SHOULD BE A MAJOR SAFETY CONCERN AND ESPECIALLY WITH CARS THAT HAVE THIS MUCH POWER TO THE WHEELS AND ARE CAPABLE OF THE SPEEDS THESE MODEL CARS CAN OBTAIN. THIS IS TOTALLY IRRESPONSIBLE OF GM TO ALLOW THIS TO HAPPEN AND NOT RECALL THE WHEELS AND REPLACE THEM WITH ONES THAT DO NOT CRACK, ESPECIALLY ON CARS WITH SUCH LOW MILEAGE.
