Power Train Problems of Toyota Corolla - part 1

Toyota south atlanta in morrow, georgia, released my vehicle after a factory warranty repair for transmission failure. However, they failed to properly complete or verify the repair. The dashboard is now throwing critical error codes stating 'a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected' and 'a malfunction in the vsc, trac, or hill-start assist control system has been detected. ' additionally, their own technician documented that my front brakes failed. They forced me to drive away without a safety waiver, and a front brake pad has since completely fallen out in front of my home . The vehicle suffers from total mechanical transmission and brake failure.

I purchased a 2023 Toyota Corolla le as a Toyota gold certified pre-owned vehicle on March 8, 2026 at 61,387 miles. Within 30 days of purchase I began experiencing the following safety concerns: •vehicle revs to 5,000-6,000 rpm unexpectedly •violent jerking while driving •vehicle stalls on April 7, 2026 I brought the vehicle to the selling dealership. The technician confirmed experiencing the jerking and stalling personally during a test drive but documented it as “common operation” and “operating as designed. ” I disagreed with this assessment in writing on their service document. A second Toyota dealership subsequently found cracked motor mounts and transmission mounts in multiple locations on a 3 year old vehicle. Replacement of these components did not resolve the issue. Transmission fluid drained at service was nearly black in color on a gold certified vehicle that supposedly passed a 160-point inspection including transmission health check. The vehicle is currently at the dealership unresolved after nearly two weeks. The stalling and rpm surging present a serious safety hazard particularly at highway speeds. I am requesting this be investigated as a potential safety defect.

Description of safety issue: the concentric slave cylinder (csc) on my 2019 Toyota Corolla hatchback 6-speed manual failed during normal driving at around 60mph, creating an immediate and uncontrolled safety hazard. The clutch pedal depressed fully to the floor while I was shifting from 5th gear to 6th gear and the vehicle became unable to be shifted out of gear, leaving me unable to properly control vehicle speed or movement. The only way to release the transmission was to physically reach down and lift the clutch pedal up with my foot while attempting to drive. Critical safety concern - shared brake and clutch fluid reservoir: on this vehicle, the brake fluid reservoir and clutch hydraulic system share a single reservoir. When the csc fails and leaks fluid, brake fluid is consumed directly from the same reservoir that supplies the braking system. A csc failure does not only result in loss of clutch function — it results in loss of brake fluid, and with sufficient fluid loss, partial or complete brake failure. This is not a theoretical risk. This vehicle can fail in a way that simultaneously removes the driver's ability to control vehicle speed via the transmission and reduces or eliminates braking capability — both at the same time, without warning I am requesting that NHTSA investigate this as a safety defect and consider whether a recall or service campaign is warranted given the risk of simultaneous clutch and brake failure on these vehicles.

Premature slave cylinder failure at ~70k miles. Suddenly started leaking brake fluid profusely. Inspected and confirmed by Toyota dealership. No symptoms prior to failure. Clutch stopped functioning, unable to shift while driving. Pulled over to inspect and all of the brake fluid had leaked out. Refilled brake fluid and bled system, reservoir leaked to minimum fill line within 24 hours.

Clutch release bearing/slave cylinder failed at 29,900 miles. Without warning or unusual symptoms, clutch pedal stuck to floor and was unable to shift gears without manually pulling clutch pedal up.

The clutch slave cylinder in my 2019 Toyota Corolla hatchback failed, causing brake fluid to leak out. The leaking fluid contaminated the clutch assembly, resulting in both the slave cylinder and clutch needing replacement. The failed components should be available for inspection from the repair facility upon request. The failure led to a loss of proper clutch operation, which made it difficult to shift gears and control the vehicle. This created a risk of stalling in traffic or being unable to accelerate when needed, increasing the potential for a collision, especially in busy or high-speed driving conditions. Yes, the issue was diagnosed and confirmed by the dealership. They identified the failed slave cylinder and verified that brake fluid leakage caused contamination of the clutch, requiring replacement of both components. The vehicle has been inspected by a service technician/mechanic at the Toyota dealership. Prior to the failure, there were no warning lights or dashboard messages indicating a problem. The issue appeared suddenly when the clutch began to malfunction due to the fluid leak causing me to not be able to shift gears and the clutch pedal not returning.

6 speed manual transmission. 79k miles. Vehicle was checked at a dealer due to a sluggish clutch. Dealer found low brake fluid, but no problems with the clutch. The next day the clutch failed completely and car had to be towed off the highway. Slave cylinder for the clutch is a design flaw on these vehicles.

The contact owns a 2018 Toyota Corolla. The contact stated that while driving 75 mph, there was an abnormal whining sound coming from the vehicle, and the vehicle failed to accelerate while depressing the accelerator pedal. The contact stated that the tachometer was raised to high levels while exiting the highway. While at a stoplight, the vehicle hesitated while accelerating with the check engine warning light illuminated on the instrument panel. Due to the failure, the vehicle was towed to an independent mechanic. An obd2 scanner was used to diagnose the vehicle, and dtc: p0741, p075b, p1604, p2757, p2820(x4) were retrieved, which were related to the torque converter. The contact was informed that the cvt transmission needed to be replaced, and the contact was provided with an estimate for the repair. The manufacturer was notified of the failure but denied any assistance. The vehicle was not repaired. The failure mileage was 76,099.

2019 Toyota Corolla hatchback. Complete transmission 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.

One night shortly after starting the car, I went to put the car in first gear amd as I let out the clutch, but pedal stayed flat to the floor. I was able to lift the pedal with my foot and drive the car back to safety. The next day, I drove the car to the nearest shop before anything catastrophic happens. This time, right in the shop parking lot, I lost all hydraulic pressure in the clutch and I could not take the car out of gear. I had to turn off the car to prevent it from stalling as the clutch slowly engaged without my doing. I had the car inspected by two repair shops—one quote at $3900, the other at $6600. The issue is a failed seal on the clutch slave cylinder, located inside the transmission. The seal is much too thin from factory to withstand normal use. There are no recalls for this issue, and many affected owners. This is a safety issue because the failure can be almost immediate and will leave the driver unable to take the car out of gear, leading to out of control driving.

The contact owns a 2021 Toyota Corolla. The contact stated that while driving at 20 mph, the clutch pedal failed to function as intended. The clutch pedal was stuck, and the contact was unable to shift gear. The contact forced the clutch back into neutral while holding the clutch pedal. Once the clutch pedal was released, the vehicle went into limp mode and traveled down to the floorboard. The contact pulled over to the side of the road. The contact kicked the clutch pedal upwards to continue driving back to the residence. The contact arrived at the residence and inspected the vehicle, and became aware that there was brake fluid leaking from the vehicle, and the brake fluid reservoir was empty. The vehicle was towed to an independent mechanic who diagnosed that the clutch slave cylinder had failed and damaged the clutch and the flywheel. The vehicle remained with the independent mechanic unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 65,000.

While in a parking lot, the clutch pedal suddenly lost all pressure and remained stuck to the floor, rendering the vehicle unable to shift gears. While this occurred at parked car , a sudden loss of gear engagement at highway speeds would have caused a catastrophic loss of motive power in high-speed traffic. Furthermore, this vehicle utilizes a shared reservoir for both clutch and brake fluid. A major failure of the clutch slave cylinder seals can lead to rapid fluid loss or air ingestion into the shared hydraulic system, potentially compromising braking performance. The dealership confirmed the internal clutch slave cylinder failed prematurely at only 38,000 miles. Because the part is internal to the housing, a full transmission removal was required, resulting in a total repair cost of $5,600. Despite the safety implications of a shared hydraulic failure and the extremely low mileage, Toyota has refused to cover the full cost. No warning lights or symptoms appeared prior to this sudden failure.

Hello, on October 14th 2024 I reached out to Toyota over a “engine maintenance required” message on my dash along with a check engine light. I took it to the local Toyota dealership in downey CA. After testing the engine coolant bypass valve b control circuit high failed. Toyota replaced the valve on October 21st 2024. Issuing me a 1year/12,000 mile warranty. On Thursday January 15th 2026 the drive start control malfunction warning light along with a p26ae error code displayed. Upon testing the engine coolant bypass valve b control circuit high failed again. Speaking with Toyota my vehicle VIN is not part of the csp service campaign they have for 19-23 Corolla models. I spoke with Toyota corporate and they couldn’t/wouldn’t help. This is a severe safety risk as the valve failed at a moments notice with no warning or symptoms. Additionally it can lead to engine stall and catastrophic damage, risking other drivers if engine loses power. This is an ongoing and recurring issue with rav4/corolla/cross models and Toyota is facing a lawsuit here in California from other drivers with the same problem. I would like for my VIN to be added to the safety recall as Toyota knowingly replaced the valve with the same defective part per the technician who fixed my vehicle the first time who warned me this was going to happen again. Thank you for your time and assistance in this matter.

At approximately 5 years and 2 months of ownership, with approximately 53,000 miles, the clutch slave cylinder failed in such a way that contaminated both the clutch and flywheel with brake fluid. Repair of this issue requires replacement of the slave cylinder, clutch, and flywheel, as described by Toyota of pullman in pullman, wa who performed the inspection and quoted the repair. The symptoms of this failure included an inability to shift the manual transmission between gears, most notably out of 1st gear to get to 2nd. This inability to change gears resulted in limited speed in traffic, and created an obstruction. In less fortunate traffic conditions, this speed restriction could have created a collision. Other owners of the same model vehicle online have reported active failures in traffic, some of which have resulted in damage to the transmission as well as the clutch and flywheel. Toyota appears to have redesigned the slave cylinder at least twice, implying that they know the parts for these vehicles are subpar, and there are no flywheels available for the repair, which also implies this may be an all too common repair.

My 2018 Toyota Corolla has problems with acceleration and a very large noise in the front bar that guides the wheels. It also accelerates by itself, which is why I have had to change the brakes many times. It also shakes a lot at the bottom.

Note: this has not happened to me yet, but it appears that most Corollas manufactured before 2022 or 2023 have this issue. However I did recently flush the fluid from my clutch system and it was very clearly contaminated, possibly indicating early evidence of a failure. Clutch system, specifically the slave cylinder is faulty on these vehicles. It is a known issue on these cars that the clutch slave cylinder (inside the transmission) is made out of resin and fails. When the slave cylinder fails, brake fluid from the shared clutch/brake reservoir leaks out onto the clutch and flywheel, damaging them and resulting in an expensive repair. In addition to this, the brake fluid leak results in a "low braking power" message on the dashboard, indicating a problem with the braking system. Obviously this is a safety issue that could cause an accident. This issue has been confirmed by many dealers and the solution is to replace the slave, clutch, and flywheel and flush & refill the brake fluid reservoir. The vehicle has not been inspected by the dealer as of yet, but in the interest of safety I am considering an early replacement of the cylinder. The only warnings of this issue are a clutch stuck to the floor, and in some cases a "low braking power" warning on the dashboard. A low brake fluid level may also be an indicator of this issue if caught in time. Incident report below is of the clutch flush, showing the contaminated brake fluid from the clutch hydraulic system. It's important to note that flushing the clutch is not a recommended maintenance item at any point on these vehicles as it is expected to be done with the braking system, although that won't remove contaminants from the clutch cylinder.

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.

Clutch stopped working while driving. Car has 61,000 miles.

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.

I am filing this complaint regarding a serious defect in my 2021 Toyota Corolla (manual). At approximately 42,000 miles, the clutch slave cylinder failed. This defect caused hydraulic fluid to leak and contaminate the clutch assembly, resulting in significant damage and loss of proper function. Despite the fact that this issue stems from a defective part, the dealership has refused to cover the repair of the clutch assembly, stating that the clutch is not covered under warranty. Instead, they are requiring me to pay for the repair out-of-pocket, which would not have been necessary if the damage had not been caused by the defective clutch slave cylinder. I believe this is unfair and unsafe, as the failure of a clutch slave cylinder directly impacts the drivability and safety of the vehicle. This is a significant safety issue. A defective clutch slave cylinder can lead to sudden clutch failure, loss of vehicle control, and increased risk of accidents. This is not a wear-and-tear issue but a manufacturing defect that compromises the safety of the vehicle. I respectfully request that NHTSA investigate this matter to determine whether similar failures are occurring in other Toyota Corolla vehicles of this model year. If this is a widespread defect, I urge NHTSA to take appropriate action, including a recall or requiring Toyota to cover repairs.

My 2016 Toyota Corolla suddenly showed a check engine light, and the dealer diagnosed a cvt transmission failure with code p2757. This code is linked directly to Toyota’s own TSB t-sb-0150-16 for torque converter clutch/valve-body failure. The dealer confirmed the issue and quoted me $11k to fix it. This is frightening because a failing transmission can slip, hesitate, or lose power at any moment, which puts me and others at risk. There were no early warning signs, just the sudden light. I brought it in immediately, and the problem was fully reproduced and documented by Toyota. My car is available for inspection whenever needed. Toyota corporate reviewed my case but offered very little help since my vehicle is just outside the 7-year timeframe for CA. I bought the extended warranty when the car was brand new. I have done every single service at Toyota, always on time, and my car has never been in an accident. I’ve taken care of it exactly the way Toyota told me to. This is not normal wear. This is a documented defect that puts drivers at risk and places an enormous financial burden on owners who did everything right. I’m filing this complaint because people deserve protection, accountability, and fairness, especially when a safety-related failure happens in a well-maintained vehicle. I’m only [xxx] , and I expected to own many more Toyotas throughout my life. My whole family drives Toyotas. I grew up believing this brand meant safety, reliability, and loyalty in both directions. I honestly wanted to be a Toyota driver for life. But facing an $11k repair for a known issue that Toyota already acknowledged in a TSB—without meaningful support—has broken my trust in a way I never expected. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The slave cylinder failed at 33,186k. So, now the car is needing a new slave cylinder and clutch because the clutch has been contaminated.

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.

Clutch slave cylinder failure at 26,261 miles.

Complete failure of the slave cylinder under at 62k miles. Changed fluid at 30k. Called to see if Toyota would still help with failure under warranty but did not help. Had to replace slave cylinder due to seal bursting. Left stranded on road.
