2004 4Runner rear hatch glass imploded with rear defroster on while driving and glass shattered all inside the vehicle in the back behind rear passenger seat. The loud sound when it imploded sounded like we had got shot at and scared all four of us in the vehicle thinking we were shot at. We pulled the vehicle over at the nearest pull over while driving on a coastal two lane road. We searched for any possible bullets. Did not find any and had to clean up as much possible of shattered glass that had covered all of our clothing and belongings. Had no materials to cover the rear broken window and had to continue our drive to meet family members to attend an early event at 9:00 am.

Unknown: we were on [XXX] when the car went out of control. It first spun one way and then the other way and then we hit the concrete abutment where the guardrail connects to it. We hit it head on. It was as if we were on ice or oil, unable to gain control or brake. We checked the road and it was dry. Other cars were going by with no problem. The airbags didn’t deploy.

The frame of my 2004 Toyota 4Runner, which is manufactured by Dana Holding Corporation, is the primary support structure of my vehicle, to which every piece is attached. It is the main protection against injury in a car accident. The excessive rust corrosion of the frame on my Toyota 4Runner greatly hinders the safety, crash-worthiness, and stability of my automobile, as transmission mounts, essential suspension components, and engine mounts are attached to it. Consequently, as it becomes affected by rust, it is significantly more prone to failing to protect me, the driver, in a car accident, and, furthermore, it can also cause serious accidents in and of itself. Depending on the gravity of the impact, not only myself but my passengers (my young children) can experience a wide range of injuries and even death. Because the excessive rusting of the undercarriage of my Toyota 4Runners can cause plenty of vehicle components to fail, there can be multiple causes for an accident. The following are the most common injuries people sustain after a car accident: traumatic brain injuries severe whiplash fractured bones lacerations spinal cord damages paralysis loss of limbs permanent scarring concussions internal bleeding head injuries face injuries compound fractures soft tissue damage back injuries dislocated bones knee injuries shoulder injuries herniated disc psychological injuries Unlike in the case of other models of your vehicles, Toyota Motor Corporation refused to address the problem of 4Runners. Interestingly, your company faced a previous lawsuit in 2016 concerning the same rusting problem in the Tacomas, Sequoias, and Tundras, and it was settled for $3.4 billion in 2020. Nonetheless, your company did not admit it manufactured defective vehicles.
