A critical oversight in the execution of an official Toyota Special Service Campaign (JSD) resulted in the severe premature failure of a replacement CVT assembly, creating a severe high-speed safety hazard on a highway. The vehicle experienced an abrupt mechanical lock-up, power loss, and transition into an extreme "limp mode" while operating at highway speeds. This sudden deceleration in active traffic created an immediate rear-end collision hazard and a severe handling emergency. Sequence of Events: 1. Initial Assembly Replacement (May 2019): The vehicle’s original K313 CVT transaxle assembly failed and was replaced at an authorized Toyota dealership with a factory-remanufactured unit. Review of the repair invoice confirms the physical hardware swap and CVT fluid line items were executed. However, the dealership omitted the mandatory Electronic Control Unit (ECU/ECM) software reflash mandated by Toyota Special Service Campaign JSD to prevent the internal gear-ratio control solenoid valve from cycling unnecessarily and experiencing abnormal mechanical wear. 2. The new, remanufactured CVT assembly was subsequently operated for approximately 9,000 miles with the defective original software. Then, the vehicle was returned to the same authorized dealership for a different recall at the time. The invoice explicitly documents the retro-active application of the software with: "JSD Special Service Campaign - PERFORMED SOFTWARE UPDATE." 5. Premature Secondary Failure (Current): Approximately 42,000 miles following the installation of the replacement transaxle, the unit suffered a catastrophic mechanical failure on the highway. Per official technical service data, operating the K313 CVT transaxle under the uncorrected software logic subjects the CVT to abnormal mechanical fatigue. The incomplete execution of an active safety campaign by an authorized modifier directly compromised the operational lifespan and integrity of a primary powertrain component.

SYSTEM THAT FAILED: Powertrain / Continuously Variable Transmission (CVT) and differential/transaxle assembly. The component is currently intact and available for inspection at the diagnosing dealership. SAFETY RISK DESCRIPTION: While traveling on the highway, the vehicle suffered a physical jolt followed by a loud, sustained mechanical whirring noise. The powertrain immediately dropped into an un-commanded "limp mode" that capped the maximum speed to below 40 MPH. Upon attempting to accelerate out of active highway traffic toward an exit ramp, the CVT slipped severely, causing the engine speed to fluctuate violently and rhythmically between 1,000 and 3,000 RPM while failing to transmit power to the wheels. This sudden, unexpected loss of propulsion on a highway created an immediate and severe collision hazard to the operator and surrounding motorists. DEALER CONFIRMATION & INSPECTION: The vehicle and its components have been officially inspected and diagnosed by an authorized manufacturer dealership. The dealership’s shop foreman personally verified a total mechanical failure of the transaxle and differential assembly, noting that the component is physically stuck in a lower gear. No insurance or police inspections were conducted, as the safety event did not result in an accident. WARNINGS & PRIOR SYMPTOMS: There were absolutely no warning lamps, dashboard messages, or pre-failure symptoms prior to this specific incident. Onboard diagnostics failed to provide any prior warning to the operator. Furthermore, a subsequent computer diagnostic sweep by the dealership confirmed that zero electronic Diagnostic Trouble Codes were triggered or stored, confirming a sudden, purely physical mechanical breakdown. This vehicle represents a repeat structural failure of a manufacturer-supplied safety remedy. The current Toyota dealer-installed replacement from a previous JSD campaign remedy suffered the exact highway mechanical breakdown after only 43,000 miles of operation.

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.

La transmission automatica CVT usadas en la mayoria de los toyotas, no puedes revisar si esta el aceite sucio , ya que es completamente sellada, y cuando preguntas en el dealer te dicen que con estas nuevas transmissiones no necesias cambiar el fluido(aceite ), resulta que estas transmissiones la mayoria solo duran de 50000 a 100000 millas, es increible como toyota siendo una compania de buena reputacion, nos h afectado a miles de consumidores, le comento esto porque mi auto es 2021, menos de 5 anos, con 135000 millas ,ya no tengo garantia, es frustante que todo esto lo hagan para hacer gastar mas al consumidor solo por su interes economico

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.

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.

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.

My vehicle has a production date that falls within an existing safety recall J07 but Toyota is denying coverage. The cvt is making a grinding noise consistent with the torque converter issue described in the recall and my door has a stamp with being produced in 10/2018 when this recall was in effect. However they are denying coverage.
