"On 04/09/26, I took my vehicle for regular maintenance and an oil change; no potential issues were reported. I operated the vehicle in good faith, trusting its safety. However, on Sunday, 05/03/2026, while driving at highway speeds, the clutch pedal failed and [stuck to the floor / slipped severely]. This caused an immediate loss of power to the wheels in high-speed traffic, creating a life-threatening situation and a high risk of a rear-end collision. No warning lights appeared prior to this failure."

The clutch slave cylinder failed at 48,000 miles. On the freeway, I had difficulty shifting into gear and I had cars passing me at high speeds, putting my life and others' lives at risk. This part defect is due to the plastic clutch slave cylinder failing. This common issue is well-documented by numerous other owners, with the part failing before the routine clutch maintenance cycle. My car was inspected by an independent mechanic, who said the lack of clutch pressure is due to the clutch slave cylinder failing. The worst part is that there were no warning lamps or messages before this happened. Toyota is claiming there is no recalls for this part, whic his astounding because the clutch is essential for the 6speed transmission.

Clutch slave cylinder started leaking leading to a sticking clutch pedal, making it difficult to engage the transmission with the engine, and a lower brake/clutch fluid level which could have caused braking issues if the fluid got too low.

NHTSA ODI 11711259

Clutch Slave Cylinder at 51,000 miles failed causing vehicle clutch to not return and loss of fluid. Brake fluid and clutch fluid are used in the same reservoir and could cause issues causing vehicle to not be able to stop. Vehicle has been inspected by shop and has been replicated. The part exploded and leaks fluid inside of transmission housing. This also causes the clutch to fail as-well. Vehicle has always been serviced and maintained and this is a common issue with all vehicles that have 6 speed manual transmission with varying mileage. It is not a matter of if, it’s when and due to this being something that happens with generally no warning signs can be dangerous. There needs to be an updated part that can handle the design Toyota chose for this transmission.

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

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.

Drive start control malfunction occurred when turning the car on. Second time this has happened. First time was a charcoal canister and engine coolant valve. It was replaced under warranty at 50k miles but now at 96k miles the dealer says it is not covered under the extended warranty. Not sure how this problem happened.

The "Engine Maintenance Required" message on a 2020 Toyota Corolla SE keep coming on after I have reset numerous time. The "Engine Maintenance Required" message on a 2020 Toyota Corolla SE typically indicates a problem with the coolant bypass valve, not the regular maintenance schedule. This message is distinct from the "Maintenance Required" light that usually prompts oil changes. The coolant bypass valve issue often results in a DTC code and may require replacement.

Approximately one month ago the clutch pedal on my manual 2020 Corolla went all the way to the floor and stuck in place. Had it towed to my mechanics shop and it took them nearly 2 weeks just to get a slave cylinder to replace the defective part with. Fast-forward a week later and exactly the same thing happened. According to several different threads I have read online, this seems to be a problematic situation with the manual Corollas. Hopefully I will not experience any further problems however it appears that the defective slave cylinder part is to blame.

Engine Coolant Bypass Valve failed at 42400 miles. The problem was identified and confirmed at a dealership. There was a warning message appearing on the dashboard stating that engine maintenance was required.

Engine maintenance light came on after turning on air conditioner. Vehicle information: warning light came on at 56,800 miles on 2020 Toyota Corolla, no after market modifications to vehicle. I took vehicle to Toyota dealership for diagnostic testing. Conclusion: coolant bypass valve faulty causing leaks (this can cause overheating, stalling, increased emissions, and total engine failure and also allows coolant to leak into and damage surrounding engine components, including a vehicle's electrical system, the complaint relays). Fortunately, I PURCHASED AN EXTENDED WARRANTY when I bought the vehicle new, which covered the repairs. The faulty coolant bypass valve was replaced at the Toyota dealership. Had I not purchased the extended warranty, I would of been out of pocket for said repairs.

At 55K miles for my 2020 Toyota Corolla, the Engine Maintenance Required notification popped up on my screen and is not removable. Upon further verification numerous 2020-2021 corollas have been having this issue at similar amounts of mileage. It is a faulty Engine Coolant Bypass Valve that needs to be replaced. If I were to take it in to a dealership, they would charge $500+ just as they have for many others when it should really be a recall. As of now I have not taken it to be inspected due to fear of steep labor costs. My safety is at risk because if this does not get replaced my engine will overheat causing total failure of the car, and as a 2020 model with such low mileage, this is ridiculous.

I have only had the car for a year and a half, and I have already had to replace the battery which was less than 2 years old, all 4 tires (2 at 40000 miles and 2 at 48000), and now the engine wiring harness somehow got severed and has to be replaced which is almost $6k repair!

1. First problem I had with my 2020 Toyota Corolla Hatchback SE: SAFETY RECALL 20TA07 (Backup LampsMay Become Inoperative) - 10.29.2020 2. Second problem was with the software draining the battery way too rapidly, which made me unable to start my car. I had to have a tow truck come by and he was able to recharge the battery (he knew to do that with my car instead of towing it away, because he was seeing this type of issue with this type of car a lot). I took it to my local toyota dealership and had them inspect it. They told me that they need to update the software of the vehicle and that I should not be having this problem again after. *EL1934 FIRMWARE UPDATE (5.21.2021)* 3. Third problem I had was with the temperature gauge. The needle pointer in the dash did not go up and stay in the middle between C & H. It stayed closer to C (cold). It took longer than it should have to heat up the interior of the car when I turn the heat on in the morning. I took it to my local toyota dealership and after they inspected this issue, they told me that they needed to replace the thermostat unit. *MA001 THERMOSTAT ASSEMBLY* (3.19.22) 4. Fourth problem is with the transmission. I felt jerking motions from the car when accelerating and when braking-coming to a stop. **26312 CAR JERKING UPON ACCELERATION /FOUND TRNSMISSION CODE /NEED NEW TRANS ASSY UPON INSPECTION AND HEATLH CHFCK FOUND CODE P07457F AND PO7757F SOLENOID A B BOTH STUCK OFF /REST MEMORY /NO CHANGED /FOUND NEED NEW TRANS MISSION ASSY /REMOVE AND REPLACE TRANMISSION ASSY AND PERFORM RESET AND INITIALIZATION/PERFORM HYDRULIC AND ELECTRICAL TEST /NO PROBLEM FOUND /PROBLEM AT THE TRANSMISSION ITSELF CAR JECKING UPON ACCELERATION** Transmission, Automatic - Replace* (12.10.2022) I found out online that the transmission problem was known for 2018-2020 corolla hatchbacks, but Toyota did not replace it immediately. There should be a general recall for the transmissions for these vehicles ASAP!

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.

My vehicle has 20k miles on it and during acceleration, the CVT would not upshift was bouncing off the rev limiter. I had no controls over the Paddle Shifts or Electronic manual shifter controls. Tried to accelerate again, and bounced off the rev limiter again. Shortly after the CEL came on and the vehicle went into LIMP mode causing me to lose control of accelerator pedal, and the car drastically decelerated on its own until about 35mph Yes. Transmission is currently at shop awaiting for replacement unit This issue happened during a driver education event, and therefore was not on public roads with other pedestrians. Had this happened on a highway during merging or passing on a highway, this could have caused an accident by not having control of car's deceleration, and no warning brake lights to drivers behind me could have caused other drivers to rear end me Yes. The issue was reviewed by 2 dealers and both reported the CVT was faulty and needed replacement Yes. CEL came on, and was displaying codes P2757 and P2820. Dealer pulled the following codes: P275600- Torque converter clutch pressure control solenoid control circuit performance/stuck off P281F00- Pressure control solenoid j performance/stuck off (2 trip detected) P281F71- Pressure control solenoid j performance/stuck off actuator stuck
