On the morning of 10/31/2023 I was on my way to work. I had the cruise set at 75 MPH, and I heard what sounded like an explosion/ loud bang. The truck immediately veered off to the left, hit a drainage culvert, and went airborne. With the front tire folded in, no steering was available to use. Upon inspection, while at the tow yard, the lower control arm snapped in half, as well as the CV joint (half shaft), so this was obviously the cause of the loud explosion/ bang sound that I heard. This lower control arm is made of aluminum, not steel. I could have been killed if I would have hit the culvert more square, as the truck missed the steel barrier cable posts by only a few feet, which was evident upon re-visiting the accident site two days later... the truck narrowly avoided being impaled by the barrier posts. It us unknown weather the police or insurance company inspected the vehicle when the body shop performed the repair assessment. There was no warning, just a catastrophic failure of the lower control arm.
