Adaptive Cruise Control problems of the 2025 Toyota Camry

The hybrid propulsion system in my Toyota Camry hybrid malfunctioned. The vehicle displayed multiple warning messages, including “hybrid system malfunction” and other system failure alerts. The accelerator pedal stopped responding, and the vehicle lost propulsion while driving at highway speed. The vehicle would not restart after coming to a stop. The vehicle has been towed and is available for inspection upon request. The vehicle lost power while I was traveling at highway speed during severe weather conditions (tornado and thunderstorm warnings). The car began rattling and shaking, then the accelerator stopped responding, and the vehicle gradually decelerated despite pressing the gas pedal. I was forced to activate hazard lights and maneuver to the shoulder. Multiple large trucks were traveling at high speed and did not immediately move over, coming dangerously close to striking my disabled vehicle. Because of the severe weather and approaching storm conditions, I was stranded on the highway in a vulnerable position. The sudden loss of propulsion created a significant risk of a high-speed rear-end collision. The vehicle was towed after the incident. It has not yet been confirmed whether the dealer has reproduced the failure. The malfunction occurred suddenly while driving and has not been intentionally reproduced by me. The vehicle would not restart at the time of the incident. The vehicle was towed following the incident. It has not yet been inspected by police or insurance representatives. Inspection by a Toyota dealer/manufacturer representative is pending (or currently in progress, if applicable). Approx. 15 minutes before reaching my destination, the vehicle began rattling and shaking unexpectedly while driving at highway speed. Shortly after, the rattling stopped, but the accelerator pedal stopped responding and the vehicle began decelerating. Multiple warning messages then appeared, including “hybrid system malfunction” and other system failure.

Several times when I have honked my horn on my 2025 Camry se cruise control has engaged. That is a dangerous situation if I'm trying to avoid a slow vehicle or accident and the vehicle goes into cruise control mode. Not sure what Toyota can do about this as the cruise control buttons are on the right side of the steering wheel behind the horn. Maybe it is overlapping or too close. There are auto braking cruise control options with the Camry but there is also a disengage non control mode that could lead to that accident.

The default cruise control mode on my 2025 Toyota Camry is adaptive cruise control. If you are using adaptive cruise control when driving around town the system can abrubtly brake when it should not. The two conditions when this happens are: 1. You are driving on a divided highway that has left turn lanes. If there are cars in the left turn lane the sytem can abrubtly brake. It thinks the car in the left turn lane are in your path. 2. If you are driving in the left lane of a one way street where cars are parked on the left hand side of the street, the system can brake abrubtly. It thinks the parked cars are in your path. I consider this a safety issue because drivers often follow to closely and abrupt braking might cause a rear end collision. To solve this problem, I suggest Toyota either make non adaptive cruise control the default or have an option to change the default cruise control to non adaptive cruise control.
