   About a year ago and again a few days ago, I was slowly moving my Prius forward when suddenly it accelerated at full speed. The first time I was pulling into a parking spot beyond which was a grassy area and then a stockade fence. When I felt the car lurch forward, I slammed on the brakes, but was still going quite fast. Fortunately, the collision avoidance brakes kicked in and stopped the car just before I hit the fence. In the second case, I was slowly pulling into a parking lot when again the car surged forward. This time I was able to stop the motion with the brakes myself . In both cases I was conscious of moving my foot from the gas pedal to the brake pedal. In both cases it was a hot summer day, near 90.

   On May 16, 2023 I was slowly driving out of a market parking lot when the car suddenly accelerated, full throttle, and speeded across the street (Colusa Avenue, Berkeley, CA), crashing head on into a fence. Immediately after the crash, the dashboard displayed the following: "Check Engine (!) A malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. Contact your Toyota dealer to have your vehicle inspected." The car was towed and is now at a body shop selected by my insurance company, AAA. I received whiplash, small bruises on my chest and left hand, and a scraped shin. I was taken to Alta Bates Emergency by ambulance.

   Attempted to park in my garage and overshot the turn. The brake then failed to stop and I dented my garage outer wall. I reversed my car and tried to reposition it to go inside the garage, putting it on drive. However, the brake pedal made the car accelerate and the car went on reverse. It then crashed into the neighbor's garage and crashed the door and car inside. Both the car inside the garage and the garage itself (along with the inside of the house) have been damaged.

   I was making a left turn into my subdivision after a full stop. My speed was no more than 5 MPH. The Toyota dealer informed me that the sidewall had blown and was not repairable. They had no definitive cause as to why the tire blew. The tire was retained by the dealer. The tire size is P 195/65R15 and is a Toyo NanoEnergy A41 Tire. It was original equipment on the Toyota Prius as built in Japan. I have found that the tire has no manufacturer's warranty. I just returned from a vacation three days ago driving from Hilton Head Island, SC. Had this happened on the interstate system, the results to me, my wife, or other drivers could have been very different. To the best of my knowledge, the tire has not been inspected by any party. I was not given any tire DOT information on the new tire.

    PROXIMITY SENSORS GENERATED AN ALERT THAT PARKING ASSISTANCE SENSORS NEEDED CLEANING DURING MODERATE RAIN CLEANING THE SENSORS DID NOT RESOLVE THE ISSUE. STOPPED AT DEALER TO HAVE IT CHECKED AND WAS ADVISED THAT THE SENSOR DO THAT IN INCLEMENT WEATHER AND I WOULD NEED TO LEARN TO LIVE WITH IT. IF IT WAS JUST THE PARKING SENSORS IT WOULD NOT BE AS SIGNIFICANT BUT I DID DETERMINE THE FRONT ACCIDENT ASSISTANCE DID NOT FUNCTION AS IT SHOULD HAVE - AS I APPROACHED A VEHICLE IN FRONT OF ME WITH CRUISE CONTROL THE SPEED REDUCTION THAT WAS SUPPOSED TO OCCUR DID NOT HAPPEN. HAD I NOT BEEN CHECKING TO SEE WHAT WOULD HAPPEN IF THE PROXIMITY SENSORS WERE MALFUNCTIONING IT COULD HAVE RESULTED IN AN ACCIDENT. I DID NOT ATTEMPT ANY OTHER ACTIONS WHICH RELY ON PROXIMITY SENSORS TO FUNCTION AS I DID NOT WANT TO CAUSE OR BE INVOLVED IN AN ACCIDENT. I WAS DRIVING AT THE TIME AND I EXPECT THAT ALTHOUGH THE ALERT SPECIFICALLY MENTIONED PARKING SENSORS, THE FACT THAT THE CAR DID NOT SLOW AS TOYOTA HAS INDICATED IT SHOULD LEADS BE TO BELIEVE THAT ANY AND ALL "DRIVER ASSISTANCE TECHNOLOGIES" MAY FAIL WHEN THAT ALERT OCCURS RESULTING IN POTENTIAL ACCIDENTS AND INJURIES THE VSC OFF INDICATOR WAS FLASHING AT THE TIME. *TR
