NHTSA Complaint #11600449 — 2019 CHEVROLET CORVETTE

In my 2019 Chevrolet Corvette Grand Sport, the transmission system began to malfunction, specifically related to the torque converter. This malfunction caused the transmission to shudder, creating a noticeable vibration during acceleration and driving. The unpredictable behavior of the vehicle due to the shuddering compromised control and stability, posing a risk to my safety and the safety of others on the road. The problem was confirmed by the dealership's service center, which performed a transmission fluid flush according to the service bulletin (TSB 18-NA-355) issued by General Motors. Although there were no specific warning lamps or messages, the shuddering symptom appeared several months before the repair. The dealership corrected the issue by performing the necessary service, which cost me $853.52, an amount I paid under protest as I believe it should have been covered under the service bulletin. The vehicle is available for inspection upon request, and the dealership, acting as an authorized representative of the manufacturer, diagnosed and addressed the issue.
