NHTSA Complaint #11717291 — 2021 CHEVROLET SILVERADO 2500

The vehicle experienced a sudden and complete transmission failure at approximately 77,800 miles. There was no prior abuse or modification. The failure resulted in loss of normal drivability and required full transmission replacement. The transmission was replaced with a remanufactured unit due to catastrophic internal failure. Repair costs were approximately $7,000. I am aware of similar GM transmission issues and recalls affecting comparable model years and components. Although my VIN is not currently listed under a recall, the failure appears consistent with known GM transmission defect patterns. The failure occurred while the vehicle was in the middle of an intersection in heavy traffic, resulting in sudden loss of vehicle functionality. A child passenger was onboard at the time. The incident created a significant safety hazard due to loss of drivability in an active traffic environment.
