On July 27, 2022 I was driving my 2022 GMC truck on the freeway. I was rear ended by a semi truck and the passenger side was side swiped by the semi. I was driving the truck with my wife and two kids as passengers. The truck was completely totaled. No airbags deployed and the seat belts did not restrain us. All 4 of us were wearing seat belts. Also, the drivers seat completely broke, it looked like it had been completely reclined to a laying position. A police report was made. All 4 of us were taken by ambulance to the hospital. All 4 of us needed medical care. The truck was totaled and towed, the insurance has since taken possession of the truck. There were no warning lights, service lights or any indication that there was anything faulty with the truck. We had just purchased it in February 2022. My safety, as well as the safety of others was put at risk. The semi truck driver stated he was driving 60mph. If this isn't enough for air bags to deploy, I don't know what is. The seat belts also failed to restrain us. The seat belts were completely loose and during the accident failed to secure us. Again, the drivers entire seat completely broke causing severe head, neck and back injuries.

While traveling at highway speed, the hood-mounted air vent (factory-installed component) on my 2022 GMC Sierra 3500 HD suddenly detached from the vehicle without warning. Upon separation, the vent was propelled backward, striking both the hood and the windshield. The incident occurred during normal driving conditions, with no prior indication of looseness, damage, or defect in the component. The force of the detachment caused damage to the hood and posed a significant safety risk, as the debris impacted the driver’s line of sight and could have resulted in loss of control or injury. There were no external factors (such as collision or road debris) that contributed to the failure. This appears to be a failure of the factory-installed component and its mounting system. Safety Concern: This type of failure presents a serious hazard not only to the vehicle occupants but also to other motorists. A detached component at highway speed could strike nearby vehicles, cause sudden driver distraction, or lead to more severe accidents.
