NHTSA complaint #11757407 — an unverified report by a vehicle owner.
A severe, pre-existing life-safety defect and unauthorized structural modification were discovered on my 2024 Toyota Corolla . Following a routine diagnostic check for vehicle pulling, certified Toyota technicians discovered that the vehicle's primary fuel line had been dangerously altered and was held together underneath the chassis by an unsecured wire clothes hanger. The vehicle was immediately grounded as an active fire and explosion hazard. A forensic vehicle inspection by a major insurance carrier (Traveler's) subsequently denied standard repair coverage, formally documenting that the wire-rigged fuel system was a pre-existing mechanical defect resulting from previous work done prior to my purchase of the vehicle from McCluskey Automotive. The selling dealership actively concealed an unroadworthy condition that exposed myself and my minor daughter to a catastrophic vehicle fire.
NHTSA complaint #11756720 — an unverified report by a vehicle owner.
FAILED COMPONENT & AVAILABILITY: The manual transmission Concentric Slave Cylinder (CSC) failed internally. Due to caustic hydraulic fluid contamination and severe system pressure loss, I had to replace the internal CSC unit, the clutch disc, the pressure plate, the flywheel, the master clutch cylinder, and the hydraulic clutch lines. The failed components have been retained and are available for inspection upon request. SAFETY RISK: The plastic housing of the OEM slave cylinder cracked internally, spraying caustic hydraulic brake fluid inside the transmission bell housing and completely coating the flywheel, pressure plate, and clutch friction disc. This caused an immediate, sudden loss of hydraulic pressure, forcing the clutch pedal to drop and stick flat to the floorboard. This put my safety and the safety of others at extreme risk, as it suddenly prevented me from disengaging the clutch, shifting gears, or safely dropping the vehicle into neutral while driving in active traffic.CONFIRMATION & REPAIR: A certified Toyota dealership diagnosed the issue and issued an unaffordable repair estimate of $4,800 to fix this recurring manufacturer defect. Because of this extreme cost, I was forced to drop the transmission and perform the entire rebuild myself. The total out-of-pocket cost just for replacement parts was $3,200. The vehicle has not been inspected by police or insurance representatives as no crash resulted. WARNINGS & MILEAGE SYMPTOMS: There were no prior dashboard warning lamps, error messages, or clear physical indicators before either failure occurred. The loss of clutch pedal pressure happened instantaneously. This vehicle has suffered this catastrophic internal failure twice: the original factory-installed unit (part number 31400-19025) failed prematurely at 59,000 miles. The updated replacement part (superseded part number 31400-19027), which suffers from the exact same defective plastic composition, failed again just 40,000 miles later.

On Monday, January 5, 2026 at approximately 3:15 p.m. Pacific Standard Time, in the middle of stopped traffic (leftmost lane, southbound on Van Nuys Boulevard near the Saticoy Street intersection in Los Angeles, California), the vehicle, a 2023 Toyota Corolla Hybrid LE, suddenly started slowly moving backward. The driver pressed on the brake pedal, but the vehicle did not stop. In a panic, the driver removed the key from the ignition, which immobilized the vehicle. While in the middle of traffic, the driver contacted a family member for assistance and the vehicle was towed to the driver's residence. On the following day, January 6, 2026, the vehicle was towed to a service center for inspection. It is unknown if the warning messages observed January 6, 2026 were due to the vehicle being towed. At the service center, a tire was replaced and the brake system was flushed, at the owner's expense. Afterward, the driver continued to operate the vehicle. As of August 5, 2026, this incident had not recurred.

Design issue: The 12th-generation (E210) Corolla manual transmission utilizes a CSC unit containing plastic/ABS components that owners and forum communities frequently cite as a weak point prone to premature leakage and mechanical failure. This occured to my corolla on a roadway and presented a severe safety hazard.
NHTSA complaint #11754045 — an unverified report by a vehicle owner.
I own a 2026 Toyota Corolla purchased in November 2025. The recurring problems began on December 8, 2025, when multiple warning lights appeared on the dashboard along with the message “System Malfunction – Visit Your Dealer.” The warning indicators involved several vehicle safety and driver-assistance systems. The vehicle was taken to an authorized Toyota dealership for inspection and repair. On June 16, 2026, the vehicle experienced another serious malfunction, including a “Transmission System Malfunction” warning. The electrical and operational problems continued despite dealership visits and repairs. The battery was also replaced, but this did not permanently resolve the recurring failures. During a later incident while the vehicle was being driven, multiple warning lights appeared and the vehicle lost power or shut off. There was no crash or injury, but the unexpected malfunction while driving created a serious risk to the driver, passengers, and other motorists. The dealership has also addressed an issue involving the shift lever position sensor and corrosion or water intrusion. I do not know the exact component responsible for all of these failures. However, the problems have occurred repeatedly since December 2025 despite multiple dealership visits. Toyota was notified and corporate Case No. 260630000224 was opened. I have not received a permanent explanation or resolution, and I am concerned that the vehicle could unexpectedly malfunction or shut off again while being driven.
NHTSA complaint #11751940 — an unverified report by a vehicle owner.
The CVT transmission on my 2016 Toyota Corolla initially suffered a complete mechanical failure and was repaired on 01/08/2024, forcing me to pay $3,696 out of pocket for a replacement at an independent shop. Last week, the transmission experienced issues again, and this time a certified Toyota dealership serviced it for free under an active factory recall. This proves the vehicle has a documented factory defect. However, Toyota is currently refusing to reimburse me for the original $3,696 repair expense incurred due to this exact defect.

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.

"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."
NHTSA complaint #11737720 — an unverified report by a vehicle owner.
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.
