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.

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. …
At 4 years and 1/2 old car 2020 Corolla XSE an Engine Maintenance Required SEE DEALER light turned on. Did diagnostic with OBD 2 scanner at two locations auto body shop and Uto zone. Nothing appears. It is in fact a NEEDED future recall since thousands if not more people have encountered the same. It is a Coolant By Pass Valve. Cost is only $99.53 + tax at dealer. Problem is that should be under warranty or extended warranty or recall. Dealer likes to charge $800 (180-200 for diagnostic, $110 part, $400 labor. Part only takes 30 minutes to install. I should be able to buy at dealer for $110 and have them install for free or pay 30 minutes of work time = $85. 1 hour is about $175. So instead of trying to be billed $800 I should only be billed for $85 labor (30 minutes) + $110 part = Brand total of $105 USD. …
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. …
I am having a problem with my 2020 Toyota Corolla's brakes. I live in [redacted] . 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.
What component or system failed or malfunctioned: complete slave cylinder failure resulting in loss of braking and ability to shift. Luckily I was traveling at a low rate of speed when this happened, but if this happens to anyone on the freeway or while turning against traffic for example they would have no control of their car and could be seriously injured. I took it to the dealership and they diagnosed it as a slave cylinder failure at only 70k miles. This is incredibly pre-mature. The vehicle has not been inspected by the manufacturer, only the dealership but I am trying to escalate the issue. No warnings at all, I regularly get my car serviced on there were no instances of the clutch acting strange or brakes losing power (because the clutch and brakes share the same fluid reservoir) prior to this incident.
