On October 22, 2026, the heated driver's seat in my 2019 Nissan Altima caused what appears to be a burn injury to my lower back. I was wearing both a tank top and a sweatshirt while using the heated seat. I discovered the injury afterward. The injury included an open, raw area of skin on my lower back, which I documented with photographs. I am extremely concerned that the heated seat generated enough heat to cause an injury through multiple layers of clothing. This presents a serious safety hazard to drivers and passengers, particularly because an occupant may not realize an injury is occurring until afterward. I am concerned about a possible malfunction or defect in the seat heating element or temperature regulation system. The vehicle has not yet been inspected for this incident. I have reported the injury to Nissan Consumer Affairs and requested a formal investigation. I am requesting that NHTSA investigate this potential safety defect to help prevent similar injuries to other vehicle occupants.
