2011 Chevrolet Corvette Powertrain & Transmission Problems

I HAVE A 2011 CHEVROLET CORVETTE WITH ABOUT 34,000 MILES ON IT. THE AUTOMATIC TRANSMISSION SHIFT LINKAGE CABLE HAS PLASTIC GROMMETS THAT CONNECT THE SHIFT HANDLE TO THE TRANSMISSION. THE PLASTIC GROMMETS BROKE DISABLING THE ABILITY TO SHIFT OUT OF PARK INTO ANY GEAR. I WAS PARKED IN A PARKING LOT WHEN THIS HAPPENED. MY CONCERN IS IF THIS HAPPENS WHILE DRIVING YOU WILL LOSE CONTROL OF THE CAR.

GEAR SHIFTER FAILED. STUCK IN DRIVE...HAD TO SHUT CAR OFF TO STOP MOTION AND AVOID COLLISION. OTHER REPORTS INDICATE NUMEROUS SIMILAR FAILURES ON LOW MILEAGE CORVETTES.

CHECK ENGINE LIGHT COMES ON AND HAS A P0442. I CAN SMELL FUEL AFTER LIGHT COMES ON MOSTLY AND LOWER SPEEDS (UNDER 10 MPH) AND ALWAYS AT A STOP. WHEN I FILL UP IT IS A DEFINITE UNDER BOTH CIRCUMSTANCES. I WAS POINTED TO A NEW GAS CAP. I'VE REPLACED 2 AND THE CODE CONTINUES TO RETURN AND THE SMELL OF FUEL IS OUTSTANDING AND SEEMS UNSAFE FOR THE POTENCY.

TRANSMISSION LINKAGE GOING BAD DUE TO PLASTIC BUSHING NEXT TO EXHAUST

I HAVE A BAD RATTLE NOISE COMING FROM UNDER THE CAR. IT SOUNDS LIKE SOME BEARING, OR MARBLES ARE LOOSE. IT HAPPENS WHEN CAR IS IN DRIVE AND AT A STOP LIGHT OR PARKED. MY PERSONAL MECHANIC PINPOINTED THE ISSUE TO THE TORQUE TUBE/ FLEX PLATE BEARINGS.

CLUTCH PEDAL DOES NOT RETURN. PEDAL IS AT APPROX. 1/2 HEIGHT UP FROM FLOOR SURFACE THAN WHAT IT SHOULD BE ... PEDAL THROW IS MINIMAL.. HOWEVER, CLUTCH SYSTEM WORKS CORRECTLY. I WAS DRIVING ON A ROAD 40 MPH WHEN I REALIZED THE PEDAL WAS NOT IN ITS NORMAL POSITION

ON 8/4/2017, I WENT INTO REVERSE AT A PARKING LOT AND A/T SHIFT BECAME LOOSE. COULD NOT SHIFT INTO DRIVE AND ONLY COULD MOVE BACK REGARDLESS OF GEAR SELECTED. THIS MALFUNCTION COULD HAVE LET ME EXPOSED TO INCOMING TRAFFIC. A MECHANIC FRIEND OF MINE FOUND THAT A BROKEN BUSHING AND STRETCHED SHIFTER CABLE WERE CAUSING THE PROBLEM. MY CAR IS LESS THAN 32 000 MILES AND WELL KEPT.

WHILE DRIVING I WOULD HEAR RATTLING NOISES COMING FROM UNDER THE VEHICLE. I TOOK IT TO A REPAIR FACILITY AND IT WAS DISCOVERED THAT A PROPELLER SHAFT BOLT INSIDE THE TORQUE TUBE ASSEMBLY CAME LOSE AND DAMAGED THE BEARING INSIDE THE TORQUE TUBE. IT IS MY UNDERSTANDING THAT THIS COULD HAVE CAUSED THE TRANSMISSION TO FREEZE/FAIL, LOSE CONTROL AND CAUSE AN ACCIDENT. I HAD TO HAVE THE ENTIRE TORQUE TUBE ASSEMBLY REMOVED AND REPLACED. THIS OCCURRED ONE WEEK AFTER THE EXPIRATION OF GM'S FIVE YEAR DRIVETRAIN WARRANTY.

VEHICLE PARKED ON LEVEL GROUND IN STORE PARKING LOT. PERSON PARKED NEXT TO MY CAR STATED, HEARD "WEIRD NOISES', COMING FROM VEHICLE THEN IT STARTED TO ROLL INTO DYED SWAMP. CAR EQUIPPED WITH AUTOMATIC TRANSMISSION.VEHICLE WILL NOT START WITH TRANSMISSION IN PARKED POSITION BUT WILL CONTINUE TO ROLL FORWARD WITH TRANSMISSION IN PARKED POSITION ON ITS OWN. AIR BAGS WAS NOT DEPLOYED & HAD TO BE TOWED. TRANSMISSION PROBLEM? *TR

OPERATING VEHICLE IN HEAVY TRAFFIC, STOP AND GO FOR 30 MINUTES. ACCELERATING FROM TRAFFIC LIGHT, MAKING GEAR CHANGE FROM SECOND TO THIRD AT 25 MPH CLUTCH PEDDLE WENT TO FLOOR HARD, UNABLE TO COMPLETE GEAR CHANGE. VERY DANGEROUS SITUATION WITH NO POWER, TRAFFIC BEHIND VEHICLE MADE HARD STOP TO AVOID HITTING MY CAR. CAUSED MAJOR TRAFFIC JAM UNTIL VEHICLE COULD BE PUSHED OFF ROAD. *TR
