Toyota Corolla 2019

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.

The contact owns a 2019 Toyota Corolla. The contact stated while driving at 60-65 MPH, the vehicle shut off and lost electrical power. All the instrument panel warning lights including the lane departure assistance warning light illuminated. The contact was able to veer to the side of the road. The vehicle failed to restart. The contact then refilled gas in the vehicle with assistance and was able to restart the vehicle. However, the failure reoccurred while driving and the vehicle failed to restart after several attempts. The vehicle was towed to an independent mechanic but was not diagnosed or repaired. The contact was able to restart the vehicle and drove to his residence. The contact stated while at a complete stop, another vehicle driving at 45 MPH crashed into the rear end of his vehicle. The air bags failed to deploy and the seat belts failed to engage. The contact sustained soreness and bruises on the upper and lower back and on the right arm and right shoulder. The passenger occupying the front passenger seat sustained head and neck injuries from slamming their face on the dashboard. The passenger occupying the rear passenger seat sustained whiplash, and neck and back injuries. The contact was able to drive to a hospital where the two passengers and himself received medical assistance. A police report was filed. An unknown dealer was notified of the failure. The manufacturer was notified of the failure but did not provide any assistance. The vehicle was not diagnosed or repaired. The failure mileage was approximately 13,000.

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.

I drove my car to get gas on November 24, 2019. After I got full tank of gas, I cannot start the engine. The engine would make a noice like coughing, and whole car would shake, all the Electric (lights, meter, music) would be on, but the engine would go back to 'dead'. On the display screen, it would show the 'battery' warning icon. I immediately tried jumpstart, but I still cannot start my vehicle so it's not simply a batteries problem. (Actually, I think the battery itself has no problem.) The dealership was not in service on Sunday, so I have to paid to get my car towed at the night- drop. Before the guy towed my vehicle away, he tried to start my vehicle again and it cannot be start. On Monday morning the dealership examine in the vehicle but they claim they found nothing wrong. All the test come clean and they wanted me to come and take my vehicle. But when the technician was about to get my car, he himself cannot start a vehicle again or it takes a long time for the vehicle to start. So they keep the car three more days to test but today they called me, and still telling me the vehicle has no problem. The car clearly has some problem! And actually this is the second time that it happened. The first time happened when I parked my car at my office buildings parking lot, and at night after work I cannot start the engine. Same problem. That time I wait for two minutes and I can start the car back on again. But the same problem did exist before, and it has a recurring problem. I'm now very worried about my car, I fear that the same problem would happen again, and I don't feel safe driving it.

12/12/21 I suffered a mulitple deer strike imploding the windshield and collapsing the roof. Two months later my restored car was returned to me on 2/4/22. It had noxious, concentrated fumes inside from adhesives and sealants not allowed to escape; I stuck my fingers with glass on a shelf under the dash; and I got blasted in the eyes and face with fine glass debris that were still in the defroster vents/ducts. It took 5 medical treatment visits to get my left eye healed. Toyota Brand Engagement Center Case 220720000770 states Toyota glass when broken should not be smaller than the size of "pebbles" and had no record on file of glass breakage turning into fine powder. An independent expert/owner of a third party body shop, Ridgeway's in Berryville VA., had advised he had a inquisitive discussion confirming with the recently-assigned ERIE Insurance Claims Adjuster, unrelated to my case, on other accidents where Toyota glass had been very difficult to clean up as it was in fine powder form, where other auto manufacturers were not. My prior accident and after accident incidents images and emails state MY original accident's glass damage resulted in about three forms of glass debris: fine glass powder as the greatest component everywhere and blown into my eyes; some glass crystals the size of a few grains of salt; and some glass shards, paper-thin laminated shards, that closely resembled the form of fish scales. I had used the words and provided images it looked like it had snowed all over the car's interior and me from the original accident. There are some 150 pages of documentation available for review.

I purchased my 2019 corolla hatch manual new. Before even 9000 miles I started having transmission issues. I could not shift into first when the car was cold. It was like hitting a wall. I had to cycle through all the other gears before it would go back into first. I took it to Toyota. They were unable to replicate the issue. It happened so sporadically I asked the technician what would happen if I had transmission issues in the future since they were unable to witness the problem. He assured me that the issues were documented, and it would not be a problem at all. Now at 30000 I am having serious issues. The clutch is engaging late, it is chattering in first and second and there are metallic fragments in my transmission fluid. The entire transmission and clutch assembly is going to have to be replaced. Toyota is stating that it will probably not be covered by my warranty because the clutch is a wear item. I've driven a manual for decades. I've put over 100000 miles on a Toyota clutch I previously owned that still worked perfectly when I sold it. This issue is not a driver caused issue. The 2019 is notorious for transmission and clutch issues if you search any kind of forums. The automatic transmission was recalled; however, the manual owners are just up creek without a paddle because Toyota can claim it's all a wear issue caused by the driver. I have not received a decision from the warranty department yet, but I am pretty sure it is not going to be covered by the warranty. A car should not have transmission/clutch issues prior to 9000 miles and be at the owner's expense especially if it is documented.

At around 36,500 miles, my Toyota Corolla began experiencing issues with the coolant bypass valve, leading to engine overheating. This malfunction has significantly impacted my ability to drive safely, as the vehicle displays a notification every five seconds, obstructing my view of the digital speedometer and making it difficult to accurately monitor my speed. The issue was not indicated by a check engine light but a persistent "Engine Maintenance Required" message. This defect poses a serious safety risk, and there's a potential class-action lawsuit in progress regarding this very issue, suggesting Toyota might have known about the defect but failed to disclose it. The faulty component is not available for inspection upon request. As more people began to experience similar circumstances, it could lead to fatalities. Other participants to the forums says the issues start when their covered warranty expires. Within these forums there's a inconstancy of service centers honoring fixes, with no cost, knowing that there is an issue. I took the car to both a third-party mechanic and an authorized dealership, and both confirmed the problem. I was quoted $732.85 for the parts and labor within my area. I also called Toyota Global which I was told "a low mileage car shouldn't be having this issue", however, there are countless of forums saying otherwise. **Toyota Models Affected** 2019 Toyota RAV4 2020 Toyota RAV4 2021 Toyota RAV4 2022 Toyota RAV4 2023 Toyota RAV4 2019 Toyota Corolla 2020 Toyota Corolla 2021 Toyota Corolla 2022 Toyota Corolla 2023 Toyota Corolla [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2019 Toyota Corolla Hatchback. The problems started on July 21st, 2025. While driving my 2019 Toyota Corolla Hatchback, I noted white exhaust smoke, even after the engine was warm. One week prior, I had filled the coolant reservoir, but when I checked it, the coolant was almost gone again. There were no visible leaks or puddles under the car. I refilled the coolant, but within days the car began shaking severely upon startup and emitted a coolant-burning smell. 5 minutes after, multiple warning lights illuminated on the dashboard simultaneously. I replaced the car battery, and the warnings disappeared. However, while merging onto the freeway, the same warning lights came back, the car lost power, and I could not accelerate above ~25 mph. If this occurred in heavy traffic, it could lead to a serious collision. I exited the freeway and had the car towed. DTCs from the independent mechanic and the Toyota dealer included: P11ED00 P030085 P030027 P030200 (Cylinder 2 misfire) C142571 (Stop light relay actuator stuck) U1117 B2284 B15AD The Toyota dealer identified a “Port Injector #2 malfunction” and recommended replacing all four injectors (~$2,000) but could not confirm this would fix it. They noted a coolant-burning smell but advised addressing the misfire first before further diagnosis. There is an active class action lawsuit alleging that 2019–2023 Toyota Corolla and RAV4 models have defective coolant bypass valves that may cause engine issues, overheating, or coolant loss without visible leaks. This matches the coolant loss, white exhaust smoke, and eventual power loss while driving. I request that NHTSA investigate this issue in connection to the reported coolant bypass valve defects affecting 2019–2023 Toyota Corolla models.

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.

While driving my 2019 Toyota Corolla Hatchback XSE, I lost almost all power to my accelerator and a check engine light appeared on my dash. I came to a stop and stalled the vehicle, once it stalled I turned the engine back on and shifted into reverse a felt and heard a loud clunk noise coming from right under my car and its not only shifting into reverse is the loud noise active but its also shifting into drive from reverse. I scanned my vehicle with a aftermarket scan tool and got 2 exact same codes for "Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off" and then two more codes for "Torque Converter Clutch Pressure Control Solenoid Control Actuator Stuck On". My torque converter in my CTV transmission failed. I was not at a risk of putting other people or myself in danger but if would have if i was moving faster at the time this happened. I have done my research on the recalls that are active on this vehicle and on the Toyota OEM TIS website there is only 1 recall that was taken care of in 2021 for the fuel pump and then there is a Warranty Enhancement Program for the Flow Shut-off Valve Coolant Leak. I did not find anything on that Toyota TIS website about the CVT recall but when i search my year, make and model on the web, I see that there is a recall for about 3,400 vehicles in the USA and nearly 1,000 in Canada that have a active recall for the CTV. I also saw the recall consequence and it matches up with what happened with my Corolla. I have attempted to contact 5 difference Toyota dealerships in my state to have them help me figure out the issue I am having with my vehicle not being listed in the recall but my CTV just failed. No one has reached back out in the past two days and I am continuing to call almost 3 times a day. I would like some clarity on how I should go about handling this issue.

On August 28, 2023, I purchased two Yokohama Avid Ascend LX BW tires, size 205/55R16. I was charged $209.19 for each tire, plus another $129.95 for a 4-wheel alignment. The total for the two tires and alignment was $549.16. I had these tires for a little over one month before this incident. On October 4, 2023, after driving about eight miles on the freeway at around 60 to 65 mph, I pulled off the freeway to buy gas. When I started to leave the gas station, I noticed my tire warning light was on. I got out of the car and noticed the left rear tire was low and going flat. I drove home (less than one mile) and called a towing service. The towing service did not arrive. So I sprayed canned air in the tire and drove to the tire shop. The tire shop person said the tire was not repairable and showed me a large hole in the tire tread with what looked like fraying around the hole. The person said he could not tell what caused the flat but suggested it may have been aggravated by heat. It was about 95 degrees outside. They put the spare on my car. I called the dealership where I bought the tire, and they said to take it to an affiliated dealership, which I did the following day. That dealership person took pictures of the tire but did not know what caused the flat. They said they would have to order a replacement tire, which did not arrive until October 6, 2023. They charged me another $36.16 to install the replacement. For the large price charged, these tires should have been durable, reliable, and trouble free. My efforts to contact Yokohama were returned “undeliverable.” I am concerned about the safety and reliability of these expensive tires. If these tires are affected by heat, they should not be sold in the western United States where the climate is often hot in the summer and fall months. Anyone selling such tires should issue a warning if they are affected by heat.

Waiting at a stop light, The light turns green and I go to pull through the intersection with the intention of going under the overpass to get on the freeway. When the car gets to about 10-15 mph The car makes a pop noise & stalled. It felt like suddenly it was dragging a lot of weight and slowly I guided it to the right side of the road under the overpass for the freeway. I tried to start the vehicle and I didn’t do anything I couldn’t move the shifter and that’s when I knew the transmission had to of been the issue. So I called roadside assistance through my insurance they said it would be 90 minutes I had to wait underneath the freeway with the vehicle. A AAA tow truck driver that was about to board the freeway stopped even though he didn’t have the call And tried to see if I had AAA so he could tell me, I did not So he got in to see what was wrong with the vehicle immediately you could tell the shifter he then pulled out what he called the belief shift override and he put a screwdriver To release the shifter I get it into neutral so when the tow truck driver showed he could tow it. I had called Toyota to make sure that I could have the car towed there he said that’s fine. When I arrived to the Toyota dealership the service department was closed because it was Sunday which I understood but I had to be to work at nine and it was already close to two. I have two sons that were both at their daycare/babysitter which I would’ve need to return to pick up at 6 PM 7 PM the latest. All the representatives had no help for me even with it being my third car from the dealership. The Toyota Corolla LE is a 2019 with only 29,149 miles on it. I’m a light driver the vehicle goes to work & the grocery store. I had a service appointment Scheduled for August 6 at 7 AM For a basic service check fluids rotate tires, no oil change, received email 8:20am Claiming I canceled appointment. Night before incident check engine light came on
