2020 Toyota Corolla Brakes Problems

I am having a problem with my 2020 Toyota Corolla's brakes. I live in [XXX] . In the winter when the car is cold the brakes work normally. When the car has been driven for a while, the car has warmed up, and the brake fluid has thinned, the brakes behave abnormally. When I stop at a red light, after 20 to 40 seconds, the brake pedal slowly drops towards the floor. My understanding is that this could indicate a problem with the master brake cylinder. My fear is that there could be a sudden failure of the cylinder causing an accident. I brought the car to Rudy Luther Toyota in Golden Valley. When I brought the car in, it was warm and the brakes were malfunctioning. Unfortunately, they let the car sit for several hours, the brake fluid cooled, and the mechanic was unable to duplicate the problem.

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.

While operating our 2020 Toyota Corolla hybrid at a slow speed in a parking lot, we began to apply the brakes as we pulled into a parking stall. As the brakes were applied , the vehicle suddenly lunged forward with abrupt force. Both tires left acceleration marks on the painted concrete curb and the vehicle struck a large concrete pillar with such force that the pillar was partially dislodged from the ground. The vehicle was brought to a Toyota dealership and the sales management was notified of the incident. We also filed complaint with the Toyota Corporation. We were contacted by a Toyota Corporation representative and were told that they would conduct the vehicle inspection. Several weeks later we received a letter from the Toyota Corporation legal department which informed us of their findings. The letter conveyed that no defect was discovered and the incident had not been captured in the vehicle's computer. We informed the Toyota dealership of the results. The only assistance offered was their willingness to sell the vehicle at auction, which we adamantly declined. At this time we are making arrangements to have the vehicle towed to a recycling lot for destruction.

Front passenger side brake caliper was rusted and seized. At the time of this issue the car is two years old and had 40k miles. The car has lived its entire life in western North Carolina with me being its only owner. It has never been driven in salty conditions other than twice to the beach. The dealership refused to fix this safety issue under the platinum warranty I purchased because it is "Enviromental". This is a major safety concern. I have a 1997 suburban which gets drove in salty conditions every winter and has never one had an issue with its calipers or any operational part rusting.

2020 Toyota Corolla EPB (Electronic Parking Brake) Issue. The message "EPB Shift Interlock Function Activated" is being shown since last few months. This message never appeared in the past 2.5 yrs since I purchased the car, started showing up up only now. I took it to the dealership and they asked to keep brakes pressed while starting the car. I now keep my brakes pressed and start the car, and still I keep getting this error message. I have documented this issue and is available at https://www.youtube.com/watch?v=bTXosvPffMo Please help Toyota help address this issue. Not sure something is not working as expected in the car or if something is started to fail in the car with EPB and so it's showing up the message. The message looks like information message and looks like harmless message, but why its showing up now, i.e after 2.5 yrs of use and never before. So, that's needs to be investigated, if there is any long term impact.
