Vehicle: 2004 Dodge Ram 1500 I was the driver and sole occupant of my 2004 Dodge Ram 1500 and was wearing my seat belt. I was traveling westbound on [XXX], shortly after passing [XXX], when I was involved in a three-vehicle collision. The first vehicle stopped abruptly, resulting in the collision. I was traveling approximately 50–55 mph before the collision, and my truck sustained a significant frontal impact. Despite the frontal impact, the driver’s frontal airbag did not deploy. There were no passengers in the vehicle. The component/system of concern is the driver’s frontal airbag and Supplemental Restraint System (SRS). Prior to the collision, I was not aware of any airbag warning lights, warning messages, or other symptoms indicating that the system was malfunctioning. The exact reason for the airbag non-deployment is currently UNKNOWN. The vehicle has not yet been inspected or altered to determine the cause. The truck is currently secured at my residence in its post-collision condition. It has not been repaired, dismantled, modified, salvaged, or otherwise disturbed since the collision and is available for inspection upon request. I am reporting this incident because the driver’s frontal airbag failed to deploy during a significant frontal collision. I am requesting that the airbag non-deployment be documented and investigated to determine whether a defect or malfunction in the airbag/SRS system contributed to the failure to deploy.
