The HVAC climate control system in my 2025 Toyota Tundra Limited malfunctioned while the vehicle was idling. The air conditioning had been set to cool and was operating normally, but without any touch to the controls or any alert, the system switched from blowing cold air to blowing warm/hot air. This caused the cabin temperature to increase rapidly. Because there were no warning lights, notifications, or error messages, there was no indication that the air system had changed. The vehicle continued to show that A/C was on and functioning. The malfunction resulted in the cabin reaching a dangerously high temperature. This caused fatal heat injury to one animal and critical heat injury to another, both of which were inside the vehicle at the time. One is still undergoing medical treatment. This same type of HVAC issue has been reported by other 2024–2025 Toyota Tundra owners in multiple owner discussion groups, particularly related to the vehicle blowing warm air at idle or failing to maintain cabin temperature. This suggests a potential widespread defect, whether software-related or involving the A/C compressor control system. This presents a serious safety risk, especially for: Children Animals Disabled or elderly passengers Anyone unable to immediately exit the vehicle The vehicle remains in our possession and can be inspected. Service interactions with the Toyota dealership are documented and available. Immediate investigation is needed to determine the cause of this HVAC failure and whether a recall or TSB must be issued to prevent future injury or death.
The contact owns a 2025 Toyota Tundra. The contact stated that while the tailgate was closing automatically, her grandson's finger was at the upper closing point of the tailgate; however, the tailgate continued to close. The contact's husband put his body weight on the tailgate and was able to stop the tailgate from closing. There was no injury sustained. The vehicle was taken to the dealer, where the contact put her hand at the upper closing point of the tailgate while the tailgate was closing automatically, and the tailgate stopped closing as designed. The dealer informed the contact that they could not fix the tailgate failure to stop closing when a smaller hand or object was within the closing point. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 1,300.
