This Problem Across All Years
After starting to accelerate from a stop light ,the Dashboard had a warning message that the accelerator and brake pedals were pressed simultaneously. The acceleration stopped and the car slowed automatically. After a few seconds the warning indicator went away and the car could accelerate. The cars behind my auto had to stop suddenly. At the time. I though that I might have hit both petals at the same time. When it happened again I opened an incident report with Toyota. Incident opened on 07-19-25 Case # 250719000440. The Toyota rep told me it should be take to a Toyota dealer to diagmose any error codes.The next time the same problem occured I took it to my Toyota dealer and was told there were no error codes to indicate a problem. I have also taken the car to a local repair shop after the problem happened and was shown there were no stored errror codes.The dealer wants to have my auto for an extende time to reproduce the problem. If they need error codes to solve the issue but no error codes are recorded when the problem occurs what can they determine? I am hoping that there are other Toyota Avalon owners which might have had the same issue.

I was pulling into a parking space when the car suddenly accelerated, jumped the curb and hit a tree. The car has auto-braking but this system did not function to stop the car.

After starting car, from being parked in parking garage from 8am-5pm, the Pre Collision warning system light turned on. Vehicle currently has 20k miles on the odometer. There are numerous records in the car's onboard history of this device failing during car startup. Drove home, started next day with no incident. System is unreliable. According to the Infotainment system, the car seems to report the failure every few months.

This incident has happened twice in three years. Hence it is a very rare occurrence. Both times involved the same events. Cruise control was on. I was traveling in the left lane of the interstate highway, approaching an 18-wheel truck which was in the right lane. When I was approximately 50 feet from the rear of the truck, the truck began to enter my lane. I suspect I was in the trucker's blind spot. My car did not sense the truck. The cruise control did not disengage. The brakes did not engage. But the MOST troublesome was that the car did not respond to my pressing on the brake pedal. I had to press 4 or 5 times before the cruise control would disengage and the brakes engage. Since I was traveling approximately 70 mph, the distance between my car and the truck (each time) closed rapidly. In the first instance, the truck tire hit my right front fender. I moved to the shoulder of the road and eventually the car braked. In the second case, I avoided collision by about 10 feet. I use the cruise control frequently and in EVERY other circumstance, the sensors on my car have worked correctly and disengaged the cruise control and I have never had a problem with breaking. I suspect a blind spot in the sensor system but why, only in this situation, does the brake system fail to disengage the cruise control when i press on the brake is a very troublesome mystery to me. Answering question on web page: My safety - life threatening, No dealer consultation, Regular maintenance schedule maintained, No warnings.
