2019 Toyota Corolla Problems

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.

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.

I had recalls “repaired”, but my airbags do not work and Bob Howard Toyota told me that they work and that they only check the sensor to make sure the sensor works. My fuel pump was was supposedly replaced but I still experience issues such as stuttering, slight stalling, engine is working harder to produce normal speeds, fuel economy has depleted and I’m loosing 194 mpg after each fuel up. There are no lights on, but I have a code reader that pulls in two issues. I reported to Toyota’s customer service and because they put in the system everything is okay they were unable to do anything.

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.

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.

The emblem on my car contains a sensor/radar for adaptive cruise control and foward collision warning that is also connected to automatic emergency brakes. The safety of me and my [XXX] old are at risk because if I needed assisted braking/collision warning, my car no longer provides that. The braking on my car feels as if I am needing to apply a lot of pressure on the brake to stop completely or even to come to slower speeds to adjust to traffic. The problem was reproduced prior to me officially picking up my car on [XXX]. The estimator told me that he isn't quite sure what is causing the sensor issue but according to the calibration system it is working fine and he doesn't know how to fix the issue. As for the brakes he said that they feel fine to him. My car was inspected by Crash Champions and I have been told that my vehicle feels fine and the sensor is working fine according to the calibration system. My car did not originally have this issue until after an accident on [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Brakes are hard when pressed. Check engine light is on and when I had it checked I was told that it was an issue with the ABS.

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.

Odometer Fraud. The contact purchased a 2019 Toyota Corolla. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 45,709, and at the time of registration, it was discovered that the mileage listed on the title was 46,091. Additionally, the contact later became aware that the vehicle was a salvaged vehicle. The seller was contacted several times but blocked all communications.

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.

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.

Vehicle was involved in a fatal head-on collision. Upon inspection of the driver restraint system, the driver restraint webbing was torn. The airbags and pretensioners deployed in the collision. The maximum recorded longitudinal delta-v was -41.4 miles per hour (with recorded clipping).

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.

I hit a deer going roughly 65mph on my way to work. The hit crushed the radiator into the engine, destroyed the airbox, folded the hood, and practically vaporized the headlight. The airbag, however, did not deploy- not in the wheel or in the side curtain. I wasn't injured but thought it was strange the because the crash totalled the car (~$16k of damage) and was at a high speed. The car had one accident prior, hitting a concrete pillar at a low speed (less than 10mph) and had been repaired two years earlier. I kept every maintainence record for the car and never had any airbag lights on or service done. Because the airbags didn't deploy, the car didn't initiate the Safety Connect call to 911 or anyone else. I recently saw Toyota settled with many owners of 2019 Corolla sedans but the hatch wasn't included, but I have (anecdotally) heard of similar stories from other hatch owners. I now own a 2023 Corolla hatch and feel a bit concerned the same issue could present.

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 have a 2019 Toyota Corolla hatchback and the headlight went out. Instead of replacing the bulb Toyota has made it so you had to purchase the entire unit which is called a headlight assembly unit and that’s in the thousands of dollars the LED lights are supposed to last the lifetime of the car so it makes it really unsafe to drive at night Currently my passenger side light has gone out and like I said it’s in the thousands to replace it so I’m unfortunately not in a position where I can do that and now my driver side light is starting to flicker and starting to cut out. There’s no way to just replace a bulb you have to replace the entire unit which is in the thousands of dollars it makes it very unsafe to drive at night. And Toyota has stated that the LED lights should last the entire life of the vehicle if not longer.

The driver’s side door would not close because the latch on the body of the car to which the door attaches fell off. The dealer’s body shop stated that they have never seen this happen before and that the cost to repair including parts and labor would be $4894.52. The car was not safe to drive unless the door latch was replaced.

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.

Front Windshield wipers abruptly pause during operation causing extreme danger when driving during rain. Wipers do not resume motion unless manually prompted, only to get stuck again immediately after.

SEVEN MONTHS OLD VEHICLE, FRONT WINDSHIELD GOT CRACK BEGINNING FROM DRIVER SIDE TILL THE CENTER. CHIP IS NOT VISIBLE TO ME. POOR QUALITY OF GLASS. TOOK THE VEHICLE TO THE DEALER TO GET EVALUATED. THE DEALER MADE A REPORT OF A VERY MINOR CHIP ONE INCH AWAY FROM THE RIGHT SIDE CORNER. THE CAR HAS 6209 MILES ON IT AND GARAGE KEPT. BOUGHT IN JAN 2019. YES ITS A BRAND NEW CAR.
