2021 TOYOTA COROLLA Power Train Problems

While in a parking lot, the clutch pedal suddenly lost all pressure and remained stuck to the floor, rendering the vehicle unable to shift gears. While this occurred at parked car , a sudden loss of gear engagement at highway speeds would have caused a catastrophic loss of motive power in high-speed traffic. Furthermore, this vehicle utilizes a shared reservoir for both clutch and brake fluid. A major failure of the clutch slave cylinder seals can lead to rapid fluid loss or air ingestion into the shared hydraulic system, potentially compromising braking performance. The dealership confirmed the internal clutch slave cylinder failed prematurely at only 38,000 miles. Because the part is internal to the housing, a full transmission removal was required, resulting in a total repair cost of $5,600. Despite the safety implications of a shared hydraulic failure and the extremely low mileage, Toyota has refused to cover the full...

I smell gas whenever I drive my car. My car has less than 33,000 miles on it.

At approximately 5 years and 2 months of ownership, with approximately 53,000 miles, the clutch slave cylinder failed in such a way that contaminated both the clutch and flywheel with brake fluid. Repair of this issue requires replacement of the slave cylinder, clutch, and flywheel, as described by Toyota of Pullman in Pullman, WA who performed the inspection and quoted the repair. The symptoms of this failure included an inability to shift the manual transmission between gears, most notably out of 1st gear to get to 2nd. This inability to change gears resulted in limited speed in traffic, and created an obstruction. In less fortunate traffic conditions, this speed restriction could have created a collision. Other owners of the same model vehicle online have reported active failures in traffic, some of which have resulted in damage to the transmission as well as the clutch and flywheel. Toyota appears to have...

NOTE: This has not happened to me yet, but it appears that most Corollas manufactured before 2022 or 2023 have this issue. However I did recently flush the fluid from my clutch system and it was very clearly contaminated, possibly indicating early evidence of a failure. Clutch system, specifically the slave cylinder is faulty on these vehicles. It is a known issue on these cars that the clutch slave cylinder (inside the transmission) is made out of resin and fails. When the slave cylinder fails, brake fluid from the shared clutch/brake reservoir leaks out onto the clutch and flywheel, damaging them and resulting in an expensive repair. In addition to this, the brake fluid leak results in a "low braking power" message on the dashboard, indicating a problem with the braking system. Obviously this is a safety issue that could cause an accident. This issue has been confirmed by many...

I am filing this complaint regarding a serious defect in my 2021 Toyota Corolla (Manual). At approximately 42,000 miles, the clutch slave cylinder failed. This defect caused hydraulic fluid to leak and contaminate the clutch assembly, resulting in significant damage and loss of proper function. Despite the fact that this issue stems from a defective part, the dealership has refused to cover the repair of the clutch assembly, stating that the clutch is not covered under warranty. Instead, they are requiring me to pay for the repair out-of-pocket, which would not have been necessary if the damage had not been caused by the defective clutch slave cylinder. I believe this is unfair and unsafe, as the failure of a clutch slave cylinder directly impacts the drivability and safety of the vehicle. This is a significant safety issue. A defective clutch slave cylinder can lead to sudden clutch failure, loss of...

Clutch pedal sticks. Even after Toyota dealership bled lines. Apparent slave cylinder issue. Failure ranges from 35k to 80k miles. Faulty design using polymer is the internet’s general opinion.

I just had to replace my transmission. 2 days later I have my check engine light, secondary collision, pre collision and parking brake malfunction lights came on. There is a osc recall that could cause these issues, but they’re saying stated my specific vehicle isn’t under a recall

The contact owns a 2021 Toyota Corolla. The contact stated that while the vehicle was parked in the driveway with the engine off and attempting to enter the vehicle to clean the interior of the vehicle, the vehicle rolled away going downward out of the driveway. Due to the failure, the vehicle tugged the contact while rolling away. The contact stated that the vehicle independently came to a stop in the middle of the roadway. The contact sustained back, feet, and injuries to both legs, requiring medical attention. A police report was not filed. The Insurance Provider retrieved the vehicle at the scene. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Vehicle has numerous electrical/mechanical issues that seem to stem from an autonomous learning remote sensor. The problems include, but are not limited to 1. Seatbelt sticking on driver’s side, problem resolves itself, possibly after someone has had a good chuckle on satellite watching the driver struggle to disengage the safely belt, 2. Trunk remotely popped at speeds ranging from 0 (park) to 70mph on highway, 3. Ignition light on and off, usually correctible by disengaging and reengaging battery lead, 4. Car shutoff and burglar alarm engaged while in park, again , correctible by disengaging and engaging battery lead, 5. Car gas gauge reading false on the light side ( less than E), then after disengaging and engaging battery lead, reverts back to 1/4 tank, 6. Clock time changed, presumably after vehicle shutoff and restarted in the middle of the night. Clock reset via auto computer, etc. All incidents are usually...

I was driving home from school, and while trying to change lanes on fairly busy road on a hill and my car with a CVT transmission stalled out and a check engine light appeared on my dash with a message reading “drive-start control malfunction”. While trying to limp the car home, the engine killed power three or four times within like a five minute drive up some hilly roads and I constantly had to pull to the side and turn the car off and on just to make it up the next hill. I took it in the same day the issue were happening and they didn’t diagnose the issue until two three week after I had originally brought it in and said it was a CVT issue. A week or two prior to this happening, I was coming down a hill towards a stop light and when I get...

Car was in dealership twice in one week for jerking while driving dealership said it was abc and was so called “fixed” both times only had my car for a little bit back before I had to take it back . 3rd time in the same week my transmission went out on me while on the highway with young kids in the car and almost caused a wreck. Car got towed in was confirmed it was my transmission and a dozen other codes going off . Toyota is lucky that the semi that was behind me when this happened did not plow into me
