The contact owned a 2024 Toyota Sienna Hybrid. The contact stated while driving at an undisclosed speed, the brake pedal was depressed, however, the vehicle failed to stop as intended. No warning lights were illuminated. The contact stated the vehicle was unstoppable. The contact stated the option was to crash into the three vehicles which were coming from the opposite direction or to crash into the pole to bring the vehicle to a stop and avoid injuring pedestrians.
Moving about 55 miles per hour on right lane of I-95 the Jeep in front of me braked abruptly. I braked hard but as my Sienna was quickly slowing down to stop, the brake pad felt spongy when it was slower and as I pressed even harder, it seemed to have stopped decelerating at that slower speed and that was when my Sienna slammed into the back of the Jeep. Happened today on July 15, 2026 at around 4:24 EST. I will also file this same report to Toyota.
We had a complete tire blowout of the rear driver tire in the desert, the temperature was 108° ambient. Toyota did not mention to us nor did the dealership that the car does not have a spare tire. We were 50 miles from any service Including cell service, I had to walk a mile to find cell service meanwhile two of our kids experience heat exhaustion. It took four hours to get the Vehicle towed. In that time our children experience heat exhaustion and had to be taken to the hospital.
