2021 Chevrolet Silverado 1500 Custom 2.7 L Turbo 4 cylinder with 34,000 miles When Truck cranks and put in gear begins moving at low speed between 1-2 gear (low speed 5-10 mph forward and also in put into reverse) hard jolted severely injuring passenger. Felt like being rear-ended by another car. Passenger was hurt & required Trauma 1 EMS & 2 surgeries (Spinal Fusion Surgery) hospitalization from 12/2/2025 to 12/13/2025. The truck jolt directly caused this accident and there were many recalls for this truck yet we had no direct knowledge of this information & was never notified of any of these issues. Truck was services at same dealership just weeks prior to accident. The truck check engine light came on only after the accident. It happened on a private gated property. Only select trucks have been said to do this very hard jolted injuring passenger and owners are not made aware using Silverado 1500 trucks. Please acknowledge receipt of this report and advise. Thank you.
