Chevrolet Corvette sudden acceleration problems

Filed Jan 23, 2021 · Transmission · 5,600 miles · OH

When the vehicle is in motion, at a constant highway speed, 40 to 70 MPH,any acceleration or deceleration, causes the car to vibrate for several seconds. I feel this is a safety issue because, at times, during the 'shudder' event, the car will lunge forward.gm has diagnosed the problem as 'shudder' and has issued a service bulletin. The fix they recommend is a complete transmission flush and fill with an upgraded transmission fluid. I am assuming the oem fluid is defective. This condition is not an isolated event. It happens almost ever time speed is accelerated or decelerated. My vehicle only had 5600 miles.

I drove from gadsden al. To chattanooga tn. For a car show at coker tire. I had never had any issues with my 2008 corvette z06 before. I parked the car and it sat for approx 5 hrs. As the group of people I was with began leaving. I entered the corvette sat down buckled up push the clutch pedal down to the floor and attempted to start the car.when I pressed the start button the car lunged forward. I slammed my foot on the brake and shut the ignition off. I almost ran thru a crowd of people. When I settled down I realized the clutch pedal was stuck on the floor. The clutch master cylinder had failed.(but still allowed the car to be started in gear a major design flaw) it did not release the clutch pressure plate as was designed to do. The car was pushed down by hand to the coker garage. I came back monday .with my trailer and hauled it back to gadsden al.( I called gm and opened a case #[xxx]. I explained what happened they seem very concerned about the incident and wanted to know if anyone was hurt. I told the gm rep that was a real safety issue with the design of the corvette clutch system they did not acknowledge that this was an issue was very evasive did not answer my questions. I dropped the corvette off at chevrolet of gadsden and discussed the incident with the service manager. He said he would wait for a reply from gm. I was informed the next day that gm would not participate in the repair or admit there was a safety concern I was told the clutch master cylinder and labor were $900. I will have it repaired elsewhere I searched the internet and there are hundreds of case of clutch master cylinder failure on all types of gm vehicles but the corvette z06 is the worst . It is only a matter of time before some one will die ( or probably has already) because of gm refusal to admit and recall the vehicles to be fixed.

Unintended acceleration as I was approaching a traffic circle I started to apply the brakes, the engine started to accelerate. I applied the brakes as hard as I could and the engine continued to accelerate. I turned the off the car and it stopped but at the same time I hit the bumper of the vehicle in front of me. This is the third time this has occurred. For this last incident I checked and my foot was only on the brake peddle.

When slowing down to a stop ( at approximately 15 MPH) the vehicle suddenly accelerated resulting in hitting the vehicle in front of mine. As my car was accelerating I pressed on the brake as hard as possible but it only slightly slowed the vehicle. I put the car in neutral as it was about 3 feet from the vehicle in front of me and I hit that vehicle at a much slower speed. This is the second time this happened. It occurred previously on approximately june 2008.

From a stop, without touching the gas pedal, the vehicle surged forward as if the gas pedal had been pushed to the floor and hit the car ahead. On another occasion, over a year later, the car did the same thing, but fortunately did not hit anything. In both instances, when the car was shifted to neutral, the engine returned to idle. On both occasions, it was almost impossible to hold the car with the brake pedal being pressed with both feet. The dealership has not found any reason for this to happen. I have found multiple instances of this happening in corvettes from 1984 to 1996, some of which resulted in accidents and even death. This is the date of the second instance.
