NHTSA Complaint #11719280 — 2021 TOYOTA COROLLA

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 cost. No warning lights or symptoms appeared prior to this sudden failure.
