FAULTY HYDRAULICS IN THE TRANSMISSION SYSTEM. FAULTY SLAVE CYLINDER LEAKING FLUID AND POTENTIALLY CAUSING VEHICLE TO BECOME "STUCK" IN GEAR WHILE DRIVING OR UNABLE TO SHIFT INTO GEAR WHILE PARKED. NOT AN UNCOMMON ISSUE WITH THESE MODELS.

Beginning on April 18, 2025, my 2020 Toyota Corolla LE began experiencing repeated failures involving multiple safety systems while driving. Without warning, several lights illuminate at the same time, including: Brake System Malfunction, Pre-Collision System, Parking Brake System, Vehicle Stability Control, Check Engine, and Secondary Collision Brake System. These warnings appear suddenly during normal driving, then sometimes disappear, then return again unpredictably. These failures disable several integrated safety systems and create a serious safety risk due to changes in braking performance, loss of stability control, and disabled collision-avoidance functions. Diagnostic scans from both the dealership and an independent mechanic repeatedly show: P1578 — Brake System Malfunction P265B — Rocker Arm Actuator Position Sensor Circuit Range/Performance (Bank 1) Both codes reappear even after being cleared. The vehicle was with Loving Toyota Lufkin, TX multiple times over seven months. They received over 7,100 in insurance payments for repairs, 463 towing cost (due to the negligence of Loving Toyota) and almost 1,500 in rental cars (Paid by State Farm) but were unable to diagnose or fix the underlying failure. Loving Toyota also provided a courtesy rental for 7 weeks while they did no repairs to the car. The safety warnings continue to occur. Toyota Corporate is now involved but the vehicle remains unsafe to drive. The same code P265B is present that was present back in April 2025. This car is not safe! The problem has been reproduced by me, the dealership, and an independent shop. The vehicle is available for inspection. All scans, photos, videos, and documentation are available upon request. Date first occurred: April 18, 2025 Issue continues intermittently to present day

This is in regards to toyota CSP 24TE04 and the Engine Bypass System. This was also included in a class action lawsuit that got dropped. Engine Bypass System is faulty and shows check engine requiring replacing of Bypass Valve and or wiring. According to 24TE04 it has been affecting over 2 million cars, but not all are being fairly covered. They need to include all models with this system that were produced during this time. Thank you

When I start the car it informs me that my seat belt is not being worn. Even though it is. Then a message appears on my dash that says "Srs airbag system malfunction visit your dealer" My family's safety is at risk if ever involved in a accident with no airbag deployment.

I was driving normally to work and the vehicle stalled without warning and became difficult to steer. The dashboard displayed “engine stopped, steering power low”. The vehicle was stalled in the middle of the roadway and could not be restarted for 10 minutes. This was a very dangerous way to stop and then not be able to restart. People had to get out of their vehicles and help me push it out of the roadway. After 10 minutes the vehicle started and drove normally without any issues. The battery and alternator tested good. The mechanic can not find anything wrong. I am scared to drive the vehicle now and have an accident due to this incident.

The contact owns a 2020 Toyota Corolla. The contact stated that after the vehicle was started, the contact started driving, and a voice message was heard coming from the speaker on the driver’s side door, stating that the communication module had failed. The vehicle was taken to the dealer, where it was diagnosed, and determined that the Data Communication Module needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was informed of the failure. The failure mileage was approximately 38,000.

At 97,000 miles, the slave cylinder in my vehicle blew. My clutch pedal had stuck to the floor, and my brakes became harder and harder to press down because the clutch takes from the brake fluid reservoir. Brake fluid began to leak from the transmission, and it had to be towed in. If I hadn't come to a stop, I could have gotten in a horrible accident.

I was driving on the freeway on my way to the house my car start to make some noises and I was loosing power I pulled up on the shoulder and turn off the car because the check engine came on turn off the car again but was struggling to go into first gear
