2019 Toyota Corolla

The contact owns a 2019 Toyota Corolla. The contact stated that while driving at an undisclosed speed, the low tire pressure warning light illuminated, with several other unknown warning lights illuminated. The vehicle was taken to an independent mechanic to be diagnosed. However, the independent mechanic stated that the tire pressures were not low, and that the cause of the failure was not determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.

I was driving on a two lane state road. Two vehicles we traveling in front of me in the left lane. The further vehicle in left decide to make a sudden stop at a traffic light. The silver sedan behind that vehicle was traveling too close to react appropriately. The sedan avoid the vehicle in front of it and impeded into my lane and collide with my vehicle. My airbags in my 2019 Corolla failed to deploy.

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.

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.

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.

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.

Error message that said 'drive start control malfunction. Took 6 mos and numerous attempts to resolve. Replaced numerous parts including the fuel pump because the plastic it's made out of was just disintegrating and and cracking. This has cost thousands of dollars in parts and labor. Also getting a msg on info screen 'connected device not supported' now. Apparently toyota did an update and there was a bug in the program yet I have to pay to fix their error to the dcm.

2019 Toyota Corolla hatchback. Complete transmission failure.

The slave cylinder failed l3aving me stranded in a parking lot. Luckily I wasnt driving down the highway as the slave cylinder is also part of the brake system they use the shared brake fluid reservoir. This is a very common problem and is a 4k plus cost to fix. Not including the time that has to go into fighting the warranty companies and dealers.

The contact owns a 2019 Toyota Corolla. The contact stated that while driving at various speeds, the steering wheel became difficult to turn in either direction. The hazard, power steering, and LDA warning lights were illuminated. The message "Lane Departure Alert Malfunction - Visit your Dealer" was displayed. The contact stated that when the LDA was deactivated, a red power steering warning light was intermittently illuminated. The vehicle was taken to a local dealer, where a battery replacement was performed. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer; however, the vehicle was not diagnosed or repaired due to the cost. The vehicle was towed to a local independent mechanic, where it remained for further investigation. The manufacturer was not made aware of the failure. The failure mileage was approximately 1,488.

While the vehicle was parked and powered off, a fire originated inside the driver seat area. There was no collision, no aftermarket electrical equipment installed, and no heated seat or accessory usage at the time of the incident. The vehicle was stationary when the fire began. The fire damage was concentrated within the driver seat assembly, consistent with a suspected electrical failure involving seat wiring, seat-mounted components, or associated harnesses. This is not consistent with owner misuse or external ignition sources. The insurer (Allstate Insurance Company) declared the vehicle a total loss but declined further fire-origin or electrical defect investigation. The vehicle is at risk of being sold or dismantled through a salvage auction, which would destroy critical evidence related to a potential manufacturer defect. The vehicle is currently listed on Copart (Lot# 99091095 highlighted as ‘Run and Drive’) I have completed a Power of Attorney (HSMV 82053) per Allstate requirement, along with a limited conditions notification for evidence preservation however Allstate is refusing to accept the conditions stating their intent to sell it as salvage. This incident presents a serious safety concern involving spontaneous ignition within the passenger compartment. Similar failures pose a risk of injury, death, or property damage, particularly if ignition occurs while occupied. I am requesting that NHTSA review this incident for potential electrical system or seat assembly defects and preserve this complaint as part of any pattern or trend analysis involving Toyota vehicles.

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

My 2019 hatchback clutch failed Clutch Release Bearing and Slave Cylinder Assembly is leaking. Toyota part # 31400-19027

rattle in transmission. Car hesitates to accelerate randomly leading to unpredictable acceleration sometimes. Transmission is failing.

All 2019-2022 Toyota Corolla 6 Speed Manual Transmission cars are affected. The slave cylinder is a defective part that fails prematurely anywhere between the 20,000-70,000 mile range. The slave cylinder on this car is made out of plastic and is located inside of the transmission, when the slave cylinder fails, it leaks brake fluid all over causing the car to lock into gear and not be able to shift which is a major safety risk when there is no signs of failure. My car locked up in the middle of a busy highway and had to be pushed off the side of the road. Not only is this a safety risk, but since the part is located inside of the transmission, which is not normal, it leaks brake fluid all over the clutch and flywheel, which will all need replacement. The dealership quotes between 4-5 thousand dollars to repair, and is not covered under warranty. Toyota knows that this part is a defective part because the new models received an updated slave cylinder made out of metal, rather than plastic, but no cars have been recalled. The car was towed to my local dealership and it is currently being worked on. The incident was reported to Toyota Corporate and a case was opened to investigate this issue. Every single model made between those years are effected and has caused thousands of people to be left with an expensive repair that is unavoidable.

I believe the break booster on my 2019 Toyota Corolla is defective. This caused my stopping distance to increase significantly, making it difficult to control my vehicle and putting myself and other drivers at risk. There were no warning lamps or messages or other symptoms prior to the start of the issue on October 10, 2025. I quickly took my car to a local mechanic the next day who said I had an issue with my brake booster. To make sure this was the issue I followed up and went to a Toyota dealership for a diagnostic. They initially told me that "all brake systems components were functioning normally at this time" and that all I need to do was to change the break fluid. I did this, but the problem persisted. I then returned to the Toyota dealership for a second diagnostic. This time they noted that the brake master cylinder and brake booster are loosing pressure internally and need to be replaced. When I googled this I saw that some 2019 Corolla (and other hybrid) vehicles were included in a 2019 recall for a brake booster pump that could fail, leading to a loss of braking assist, similar to what I was experiencing. I brought this up with the Toyota brand engagement center. They said there was no recall at this time on file, but that they would put me in touch with a representative who would manage my case (case # 251015000598). The representative would not pick up my phone calls. I was not able to speak with him. After many calls, a different representative spoke with me and told me that the case was already closed and that the assigned representative said he had explained to me why. This is not true as I had not had the chance to speak with him. I am concerned that Toyota has not given my break booster pump due diligence and is dismissing my legitimate safety concern and I would like to report this safety problem to the NHTSA.

Manual transmission intermittent failure to/rough to engage first gear and reverse. Clutch slave cylinder high rate of failure/total failure of manual transmission. Transmission incidents happen at least once per day.

Faulty slave cylinders , that lead to more damage such as the clutch & flywheel and

At approximately 66,200 miles, the slave cylinder on the clutch started failing. It will be dropped off at the dealership tomorrow afternoon for repair, hopefully driven under its own power. The clutch feels spongy and friction point is unusual. This puts others’ safety at risk because the clutch could fail, causing the car to lurch forward from being stopped, and puts my safety at risk because the car could break down at any time when it finally completely fails. There are no warning lamps, just a clutch prematurely failing. This is a very common problem with the manual transmissions in this model. I purchased a Toyota for reliability, and this part should not fail for several hundred thousand miles, if ever. There needs to be a recall on these cars.
