2018 Chevrolet Corvette problems

“Inside lip of rear wheel cracked and wheel bent beyond repair, per wheel repair company. OEM make and model tire was in place and no noticeable impact was felt to cause this failure. This caused an air leak leaving me stranded at the side of the highway. Had to buy an expensive replacement wheel.”

“THE BRAKES HAVE NOW FOUR TIMES FAILED TO STOP THE VEHICLE. WHEN PRESSED THEY GET HARD, THEN GO DOWN TO THE FLOOR AND THERE'S A PULSATING FEELING. THE VEHICLE JUST CONTINUES TO GO TO THE FLOOR. ON THE THIRD OCCASION THAT IT HAPPENED, THE VEHICLE IN A NON-EMERGENCY SITUATION, WOULD NOT STOP IN TRAFFIC AND REAR-ENDED ANOTHER VEHICLE. IT IS DANGEROUS AND GM IS NO HELP.”

“I JUST PURCHASED THE VEHICLE 11-04-2019. THE TRUNK POPS OPEN WHEN I GET IN THE CAR AND SIT DOWN. THERE IS ALSO A PROBLEM WHEN BACKING UP TO PULL OFF AND TURNING TO THE LEFT OR RIGHT, THE CAR WILL START JERKING AND THERE'S A POPPING SOUND.”

“TL* THE CONTACT OWNS A 2018 CHEVROLET CORVETTE EQUIPPED WITH MICHELIN PILOT SUPERSPORT TIRES, SIZE: P285/30Z/R19 94Y (NA) FOR THE FRONT (DOT NUMBER: 4MLW) AND SIZE: 335/25Z 20 (NA) FOR THE REAR (DOT NUMBER: 4M2R). WHILE DRIVING 45 MPH, THERE WAS A VIOLENT VIBRATION IN ALL FOUR TIRES WITHOUT WARNING. THE CONTACT NOTICED THAT THE THREAD WAS SEPARATING FROM EACH TIRE. THE VEHICLE WAS TAKEN TO ROGER DEAN CHEVROLET (101 SW PINE ISLAND RD, CAPE CORAL, FL 33991, (239) 574-3326) TWO DAYS PRIOR TO THE FAILURE, BUT NO FAILURE WAS FOUND AT THAT TIME. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE AND TIRE FAILURE MILEAGE WAS APPROXIMATELY 11,748.”

“I ATTENDED A TWO-DAY NCM TRACK EVENT AT VIR IN JUNE 2019. DURING THE SECOND SESSION ON DAY TWO MY 2018 Z06 HAD A POWER STEERING ISSUE. WITHOUT ANY WARNING, I FELT AND HEARD A LOUD THUMP THROUGH THE STEERING WHEEL AS I APPROACHED TURN 3 FROM NO-NAME, I HAD VERY LITTLE STEERING ABILITY THAT REQUIRED HEAVY HANDED INPUT ON THE STEERING WHEEL CAUSING ME TO LIFT AND BRAKE TO KEEP THE CAR FROM RUNNING OFF THE TRACK. THEN I RECEIVED A DIC MESSAGE ON THE DASH TO 'SERVICE POWER STEERING GEAR.' I COME IN TO LET THE CAR COOL DOWN AND WENT BACK OUT LATER WITH NO ISSUES BUT WAS NOT RUNNING HAS HARD AS BEFORE. THIS POWER STEERING OVERHEATING ISSUE IS VERY CONCERNING WHEN ON THE TRACK APPROACHING A TURN GOING 70 TO 80 MPH. THE OUTSIDE TEMP WAS 90 DEGREES AND THE COOLING SYSTEM WAS RUNNING AROUND 240 DEGREES. THERE IS A GM PRELIMINARY INFORMATION ABOUT REDUCTION IN STEERING ASSIST WHILE DRIVING ON THE TRACK DURING HOT DAYS. BULLETIN NO.: PI1535B DATE: NOV-2017 THAT REQUIRES TO INSTALL A NEW POWER STEERING GEAR COOLING DUCT FOR 2014-2018 CHEVROLET CORVETTE.”

“8-SPEED AUTOMATIC TRANSMISSION 'BUCKS' AND 'CLUNKS' DURING ACCELERATION OR DURING UP SHIFTING. IT DOES THIS EITHER IN FULL AUTOMATIC OR MANUAL SHIFTING MODE.”
