This vehicle was involved in a tragic car accident. The passengers both suffered deep laceration to the skull and other vital parts of the body. There was a recall notice that was sent to the owner 4 months after the fatal accident had occurred. Based on police inspection of the vehicle, theyve determined there was mechanical failure to the vehicle which can be seen through a police bodycam at the police impound lot. The front passenger suffered a 6 inch deep cut to the skull according to the medical examiners report. The child in the rear also suffered a deep laceration to the ankle and foot despite being restrained in a child seat. Driver suffered a graze cut to the side of his head and survived the tragic accident after recovering from a coma he stated that the brakes did not function properly when depressed moments prior to the accident. Data recorder from the vehicle shows the driver was depressing the brake pedal the entirety of the time up to the moment of impact. This vehicle was t-boned by an suv, and this accident should have been survivable, however the passenger seat looks to be torn out of its brackets according to the pictures from the accident scene. I am requesting this vehicle be investigated as there are many vehicles similar to this one that could have dangerous defects which were outlined in the safety recall notice that was mailed to the owner. The safety recall did mention to stop driving this vehicle immediately, however this notice did not arrive in a timely manner to where anyone could have taken action immediately. I am requesting that this vehicle be inspected for not only the safety of the community its but for identifying why two people lost their lives due to a manufacture failure that could have been prevented if notification was sent in a timely manner. Thank you and I look forward to following up with someone regarding this immediate and dangerous concern. I have the original letters and when they were mailed to the owner.
