2016 CHEVROLET CORVETTE Complaints

Right rear rim cracked for the third time on my car. I noticed a slow leak after driving for about an hour earlier in the day. I get back in my car after a round of golf and notice that the right rear tire is low on air pressure. This is the third time I've had a cracked rim. I don't abuse my car, as this is a limited edition C7R, one of 500 made for the US market. My dealer admits that the rims are defective but says they can't do anything about it because GM says the rims aren't defective. Even though my car is only five years old with less than 36,000 miles on it, GM no longer makes these rims and none are available nationwide, so I'm forced to go to a aluminum wheel repair shop to get my rim fixed as there is no alternative. The original rim cracked, the $1,000 OEM replacement rim cracked (in the same place), and now the original rim repaired has cracked (again in the same area just next to where it was repaired).

The contact owns a 2016 Chevrolet Corvette. The contact stated while the vehicle was being serviced at a tire shop, he was notified that the rear driver and passenger side rims were cracked. The contact called the local dealer to inform them of the failure and ordered both rims to be replaced. The vehicle had not been repaired as of yet. The manufacturer had not been informed of the failure. The failure mileage was approximately 12,488.

I RETURNED TO MY CAR AFTER PLAYING A ROUND OF GOLF ON MONDAY AND THE CAR SAID THE RIGHT REAR TIRE WAS LOW. I DROVE TO THE TIRE STORE AND THEY FOUND THE RIM WAS CRACKED WITH NO SIGNS OF ANY TRAUMA TO THE RIM OR TIRE. I HAD THE SAME THING HAPPEN IN JANUARY 2020, AND ENDED UP BUYING A NEW ALUMINUM RIM FROM THE DEALER (OVER $1.000) BECAUSE GM SAYS THE RIM ISN'T DEFECTIVE. THE CAR THEN HAD 26,500 MILES ON IT. NOW 7,600 MILES AND A LITTLE OVER A YEAR LATER, THE NEW REPLACEMENT RIM CRACKS ON THE INSIDE OF THE RIM IN THE VERY SAME MANNER AS THE ORIGINAL RIM CRACKED. I'VE ATTACHED A PICTURE AND NOW HAVE TWO CRACKED (DEFECTIVE) RIMS IN HAND. I REPORTED THE FIRST CRACKED RIM TO NTHSA WHEN IT HAPPENED A YEAR AGO AND NOW AM REPORTING THE SECOND IDENTICAL DEFECT. DO I NEED TO DRIVE THE CAR AND HURT MYSELF VIA AN ACCIDENT TO GET YOU FOLKS TO TAKE MY CASE SERIOUSLY?

I HAVE A '16 CORVETTE Z-51 W/8-SPEED AUTO TRANS. ORDERED CAR BRAND NEW IN APRIL 2015 - TOOK POSSESSION IN SEPT. 2015. CAR TURNED 6,000 MILES IN APRIL 2021. ON A DRIVE RECENTLY, REAR END BEGAN TO EXPERIENCE A SHUDDER/ VIBRATION BETWEEN 50-65 MPH LIKE DRIVING OVER SMALL RUMBLE STRIPS. INTERNET RESEARCH RESULTED IN ME FINDING THE EXISTENCE OF SERVICE BULLETIN NO. 18-NA-355, DATED FEBRUARY 2019 AND AN UPDATED BULLETIN WITH SAME NUMBER DATED APRIL, 2020. PROBLEM IS A KNOWN PROBLEM FOR A HOST OF GM VEHICLES FROM 2015-19 WITH THE GM 8L45 AND 8L90 8-SPEED AUTOMATIC TRANSMISSIONS. APPARENTLY THE WRONG FLUID WAS INSTALLED IN THESE TRANSMISSIONS. REFERENCE ATTACHED BULLETIN 18-NA-355. TOOK CAR TO DEALER THE FOLLOWING MONDAY AND IT WAS DIAGNOSED AS HAVING THE STATED TRANSMISSION SHUDDER PROBLEM AS OUTLINED IN SERVICE BULLETIN. BECAUSE MY CAR IS OUT OF FACTORY WARRANTY BY 6-MONTHS AND GM EXTENDED WARRANTY WON'T COVER FOR THIS EXPENSE, I WAS LEFT TO PAY THE $650 TO CORRECT A KNOWN ISSUE. WHY MUST OWNERS PAY FOR GM'S ERROR? ATTACHED BULLETIN EXPLAINS THE STEPS TAKEN TO CORRECT THE PROBLEM, INVOLVING 3 FLUSHES AND INSTALLING NEW/ DIFFERENT TYPE OF TRANSMISSION FLUID - NEW PART NUMBER 19417577. TIME WILL TELL IF THIS SO-CALLED FIX WORKS. INTERNET AUTO FORUMS INDICATE SOME FOLKS HAVE HAD TO RETURN TO THE GM DEALER MORE THAN ONCE FOR THIS PROBLEM, AFTER THE FLUSH PROCEDURE. CONTACTED GM AND LOGGED FORMAL COMPLAINT -- WITH NO RESPONSE AND BASICALLY NOTHING BUT A RUN AROUND THUS FAR. AS A CONSUMER WHO PAID GOOD MONEY FOR A HIGH END PERFORMANCE VEHICLE WOULD IT NOT HAVE BEEN GOOD BUSINESS PRACTICE TO NOTIFY CUSTOMERS OF A PENDING PROBLEM RATHER THAN REMAIN SILENT ABOUT THE PROBLEM, LET VEHICLE WARRANTY RUN OUT, THEN TELL CUSTOMERS IT'S THEIR PROBLEM? POOR CUSTOMER SATISFACTION POLICY NO DOUBT! GM SHOULD BE FORCED TO OWN UP TO THIS PROBLEM AND PAY FOR THE REPAIR.

AT 627 MILES TOOK TO DEALER, TRANSMISSION WAS SLOW SHIFTING FROM 1ST TO 2ND GEAR. DEALER REPROGRAMMED TRANSMISSION. AT 2319 MILES TOOK TO DEALER. TRANSMISSION SHUDDERS AT STEADY SPEED ON HIGHWAY OR GOING UP SLIGHT INCLINE. DEALER FLUSHED AND CHANGED TRANSMISSION FLUID TO REMEDY PROBLEM. CUSTOMER CHARGED $576. CAR WAS MANUFACTURED WITH INCORRECT TRANSMISSION FLUID FOR THE 8 SPEED AUTOMATIC TRANSMISSION APPLICATION. TEMPORARY COMPLAINT #CLN19-56809

HAVE HAD THIS VEHICLE FOR LESS THAN A YEAR. TOOK IT IN TO BE SERVICED AND TO GET NEW TIRES. UPON TAKING THE RIMS OFF, THE DEALERSHIP SHOWED ME THAT 3 OF MY RIMS HAD CRACKS IN THEM. ONE OF THE THREE RIMS HAD 3 CRACKS IN IT ALL THE WAY AROUND THAT COULD HAVE BROKEN AND FOLDED AT ANYTIME CAUSE A SERIOUS ACCIDENT OR EVEN DEATH. AFTER DOING RESEARCH THIS SEEMS TO BE AN EXTENSIVE PROBLEM FOR NUMEROUS CORVETTE OWNERS FROM 2015 TO PRESENT. WORST PART IS I'M ACTIVE DUTY MARINE CORPS AND USED MY DEPLOYMENT MONEY TO BUY THIS VEHICLE THAT IS NO LONGER RELIABLE OR SAFE, AND IS NOW JUST SITTING IN MY DRIVEWAY, UNDRIVEABLE AS THE RIMS CONTINUE TO CRACK AND ARE NOT SAFE.

I WAS DRIVING DOWN I-20 AND MY TIRE WARNING LIGHT CAME ON FOR THE RIGHT REAR TIRE. I TOOK THE CAR TO DISCOUNT TIRE AND THE TECHNICIAN PULLED THE TIRE AND SAID THAT THE RIM WAS CRACKED AND SHOWED ME THE CRACK. I BELIEVE IF I HAD DISREGARDED THE TIRE WARNING AND JUST ADDED AIR I COULD HAVE HAD AN ACCIDENT IF THE RIM DISINTEGRATED WHILE DRIVING.
