On August 29, 2026, I was stopped at a red light with my foot on the brake when I noticed the vehicle moving forward even though I was pressing the brake pedal. I immediately entered a nearby parking lot at very low speed. I had significant difficulty stopping and used the electronic parking brake to help keep the vehicle stopped. While still inside, I noticed a strong burning smell and smoke. After exiting, I saw smoke coming from the passenger side. I walked to that side and saw flames coming from the area near...

The door actuator have been replaced a minimum of eight times. Huge safety risk involved since we never know if the vehicle is going to lock. Toyota continues to replace them but not addressing the underlying issue. Not sure if this is all related but the blower motor has been replaced 3- 4 times and the battery has been replaced 4 times

For the 2nd time in 5 weeks, the main wiring harness and knock sensor have been eaten and destroyed by rodents. This has caused thousands of dollars worth of damage, and it's due to the soy based wiring used in the wiring harness. I cannot keep this vehicle outside for any period of time without the threat of the harnesses getting chewed.

The contact owns a 2025 Toyota 4Runner. The contact stated that the AC outlet in the cargo area had an open ground.

Several door lock actuators have prematurely failed. The first to do so was front passenger door in summer 2024; front driver door lock failed a few months after. Most recently, approximately 4 months ago, the lock actuator for liftgate failed. This poses safety hazard in easily exiting vehicle and/or entering it if in dangerous situation.
