Toyota Corolla electrical problems

The contact owns a 2017 Toyota Corolla. The contact stated while driving at an undisclosed speed, the air bags and seat belt warning lights were illuminated. The contact stated that upon starting the vehicle, the air bags and the passenger's side seat belt warning lights illuminated. The contact stated that the front passenger's side seat was not occupied. The vehicle was taken to an unknown dealer, where the contact declined to pay a diagnostic fee because the failure was a safety issue. The vehicle was not diagnosed or repaired. The contact stated that the front passenger's side air bag and the dashboard were replaced in 2022, and the front driver's side seat belt was replaced in 2023. In addition, the wiring harness was replaced due to water intrusion in March 2022. The contact was informed that the repair was not covered under warranty, and the 12 months warranty had expired. The manufacturer was not made aware of the failure. The failure mileage was approximately 13,369.

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

The driver seat belt dont work and once in a great while it will work but even whenever it does latch it still shows the seat belt isn't on and that noise keeps going off but after a while the noise goes off but the symbol is still on the dash board. I recently got hit from behind (09/15/2025) at a red light and no air bags deployed. Im not sure if they were suppose to deploy but either way my seat belt dont work. And I know this isn't a safety matter but my radio doesn't turn off when I turn off my car and I can't lock/unlock my doors with the key fob I have to lock it with the key on the driver door. I have to take the fuse out for the radio so my battery won't die and so the radio turns off.

I am reporting an ongoing safety issue involving the Skid Control ECU and loss of power break recall on my 2024 Toyota corolla hybrid. The first time, my vehicle experienced loss of power brake assist and displayed a “Hybrid System Malfunction” message on screen. I towed my car to Toyota, confirmed it was related to the Skid Control ECU recall and repaired it under the recall at no cost, they did a software update. The second time, the exact same problem reoccurred. I had the vehicle towed again to a Toyota dealership, but this time, they refused to perform diagnostics unless I paid out of pocket for a 12-volt battery replacement. The dealership stated they cannot confirm if the issue is recall-related until diagnostics are complete, but they also refuse to complete diagnostics without me paying first. My vehicle is currently undrivable and unsafe, and I rely on it for daily transportation and work. So they made my pay for this 12v battery to do the diagnostics and now they tell me it is not recall related but one of the relays not working, the repair will be cover under warrant but i had to pay for battery and rental cars . I believe Toyota is in violation of its obligations under 49 U.S.C. §30120, which requires manufacturers to correct recall-related safety defects free of charge. This issue leaves me without a vehicle and unable to verify that the recall has been properly resolved. I have opened a case with toyota brand engagement. I am requesting that NHTSA review this case and ensure that Toyota complies with recall repair requirements so my vehicle can be safely diagnosed and repaired without charge.

The problem of windshield wipers going off either once, or at varying speeds has not been able to be reproduced by my Toyota dealership. It goes off right when I turn the car on 50% of the time and is very inconsistent. Wipers typically go off after using the turn signal, making long turns (such as into a parking spot), and driving on long curved roadways. It has been inspected and nothing has been found. There are no warning lights or messages.

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.
