The anti-lock brake system (ABS) malfunctioned when the vehicle was still very new, with only 25,000 miles. Diagnostics from two independent service centers confirmed that the ABS electronic control unit is failing due to an external failure. Both specialists stated that such a failure is highly uncommon and is a clear quality issue related to the electronic components. A critical system like ABS should not fail this early, raising serious concerns about the durability and reliability of the vehicle’s braking system.

I was going to work on 12/15/2022. There was a stop sign and I needed to take a right turn in order to join the freeway-10 east highway to head on to work. it was about 6: 40 am approximate time. There were too many cars ahead of me at the stop sign. My brakes failed to hold on while I waited for my turn. There were at least 3-4 cars ahead of me. Therefore I did not want to hurt anyone or any other car ahead of me. Therefore I veered off to my right-hand side where there was some space and tried to stop the car but it did not do so. Therefore, My car had to hit the high-way pole to come to a stop. The airbags deployed and hit me more to my right side. The car got totaled as per California casualty insurance information. I am glad to be alive. I went later to the hospital as there were no direct visible injuries.

BACK OVER PREVENTION: WARNINGS
I am not sure what the component is but I am driving and as I accelerate the gas my car will lose power to increase speed. If I am at the stop sign or stop light and I proceed to go the car will stall and not get going once I place my foot on the gas. I have reached out to the dealer by phone and when I have obtained service I am being advised that it's nothing. But I have experienced it on multiple occasions and even had an accident and nothing is being done to resolve the issue. I know that it can't be normal for the vehicle to do that and I am tired of getting the run around in regards to it. I was able to see that there has been a recall but do not see that it is in regard to me vin number. Can you please assist me with this matter. I should not be in the middle of driving or at a stop light and not able to accelerate my vehicle to a regular speed. I would like to have this matter looked into by a different Toyota dealer. Also it happens randomly and when I take to the dealership nothing is ever done and the issue is constantly being ignored. I am being told that due to no check engine light being on that my car is fine and its not. I don't want to lose my life due to the fact that I have purchased a faulty car and have not been made aware of any issues to protect my safety.
