What 64 owners told NHTSA about the 2015 Chevrolet Corvette

Driving down interstate at 74 MPH when engine acted like it wasn't accelerating and I was able to get off on an exit when car died had to have it towed to a chevrolet dealership. Engine wouldn't turn over at all. So Chevrolet did a visual inspection and said a valve spring on #8 cylinder had broke and they needed to tear into it further. So for another $1160.00 they would tear the engine down further to see what damage had been done. Chevrolet never notified me that they had a TSB on valve spring issue. Now my engine is no good. General Motors will give no assistance on repair. My engine shut down at 74 mph no longer running on an interstate.

Bad valve springs across many GM vehicles. I am not the only one that has had broken valve springs. I am well under the miles for this issue to occur.

I HAVE A 2015 CORVETTE STINGRAY WITH 35K MILES. THE VEHICLE HAS BEEN TO THE DEALERSHIP 2 TIMES ALREADY ONCE AT 11K MILES AND SECOND TIME AT 22K MILES WHERE THE CAR SHOULD SHUDDER WHILE CRUISING AT LOW SPEEDS. ALSO IN THE MORNING DURING A COLD START WHEN I WOULD SHIFT THE CAR FROM PARK INTO REVERSE THEN THE CAR WOULD DO A HARD SHIFT. TWICE THE DEALERSHIP CHANGED THE FLUID IN THE TRANSMISSION AND REBUILT THE ENTIRE TRANSMISSION SINCE THE CAR WAS UNDER WARRANTY. BUT MY CAR'S EXTENDED WARRANTY EXPIRED ON 03/01/20, IN 06/01/20 THE ISSUE CAME BACK. NOW GM IS REFUSING TO TAKE RESPONSIBILITY TO FIX THE VEHICLE. 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 WAS EMPTY TO TAKE IN SEVERAL MORE GALLONS OF FUEL.

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.

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
