| Seats problems |
The driver’s seat / passenger seat assembly, including seat rails, mounting brackets, and Smart junction box (sjb) connections if electrical adjustment was involved, completely failed during a crash. The seat lifted off the floor anchors and almost entirely came apart, including both the seat cushion (where you sit) and the backrest, leaving the occupant crushed within the collapsed seat structure, resulting in catastrophic injuries. During the crash, the seat collapsed and disassembled, exposing the occupant to extreme trauma. This caused: •pelvic fracture •broken femur, hip, and back •collapsed lung and punctured liver •foreign object from the seat mechanism punctured pelvic bone the failure directly contributed to life-threatening injuries that would not have occurred if the seat had remained securely anchored. The malfunction posed an immediate risk of death and permanent disability. Not yet reproduced under controlled conditions. The incident has been documented by police and medical personnel. The vehicle is currently in a tow yard, and we have not had access to it, but it remains available for inspection by Hyundai, NHTSA, or a qualified service center police: yes, crash scene documented. •insurance: we are unsure whether the insurance company has inspected the seat. The vehicle remains in the tow yard and has not been repaired or altered. •manufacturer (Hyundai): not yet inspected; formal inspection requested. The vehicle and seat are preserved and ready for inspection by Hyundai, NHTSA, or other qualified representatives. There were no warning lamps, messages, or prior symptoms of seat failure. The seat functioned normally prior to the crash, and the malfunction occurred only during the impact, demonstrating a sudden and catastrophic failure under crash conditions.
I am writing to report a safety issue with my 2016 Hyundai Sonata. The trunk is stuck closed and I am unable to open it using the key fob or the button on the trunk itself. Additionally, the button to fold down the rear seats is located inside the trunk, which makes it impossible to access the trunk from the rear seats. I have also tried using the keyhole on the trunk, but it does not work either. This is a serious safety issue that poses a risk to myself and others on the road. In the event of an emergency, I may need quick access to the trunk to retrieve necessary items or a spare tire, but due to the malfunction, I am unable to do so.
For no apparent reason and very little passenger usage the seat sensor for the passenger air bag is supposedly not working properly and if there is an accident the air bag may not deploy.
A screw that connects the driver's seat to the rail and car frame came out on it's own over time. Car has been used in a normal manner. Discovered the issue when getting in and out of the car and the seat started rocking and wobbling. No pieces are broken.
