2023 Toyota GR CorollaRecalls, problems, MPG & safety

“The clutch in the '23 GR Corollas is not sufficient enough for the vehicle. Even Toyota knows this as they updated the clutch not only from 23 to 24 but also from 24 to 25. I have a little over 20k miles on mine, and the clutch is so far gone that the car is not driveable. I have heard of a large handful of clutch warranties and have confirmed 7 of them. I took my car to the dealer and they want me to approve ≈$1800 of service to determine if the clutch is warrantable, but advised that if the Toyota Rep decides its not covered, I'm on the hook for the labor. This has been a well documented complaint amongst forum posts and other social media groups with GR Corolla owners. If Toyota knows there is a problem, they should issue a TSB or something so its not such a hassle.”

“Both front tires on my 2023 Toyota GR Corolla have developed severe inner-edge wear down to the cords, while the rest of the tread remains in excellent condition. This occurred at approximately 14,000 miles. The wear pattern is symmetrical and isolated to the inner inch of both front tires, indicating that it is not the result of normal driving, impact, or neglect, but rather points to a factory alignment or suspension geometry defect. I discovered the issue during a routine inspection and immediately stopped driving the vehicle for safety reasons. Tire wear exposing the cords poses a high risk of sudden tire failure or loss of steering control, especially at highway speeds. This appears to be a manufacturing or setup defect, as multiple other 2023 GR Corolla owners have reported the same pattern of premature inner-edge front tire wear on owner forums. The consistency of these reports suggests a systemic issue affecting vehicle safety. The vehicle is currently being evaluated at an authorized Toyota dealership, and the service department has communicated the concern to Toyota for review as a potential safety-related issue.”

“I am writing to file a complaint regarding my 2023 Toyota GR Corolla Circuit Edition. The issue pertains to the ECU programming, which was not properly calibrated for the wheels that came with this model. Instead, the weight and dimensions from the Morizo Edition were utilized. This discrepancy causes the vehicle to inaccurately register speed, which is a significant safety concern. The malfunctioning component is the ECU, and it is available for inspection upon request. The inaccurate speedometer readings put my safety and the safety of others at risk by potentially causing unintentional speeding, which could lead to traffic violations and increased risk of accidents. Additionally, the inaccurate speed readings can affect other vehicle systems, such as collision alerts, adaptive cruise control, and braking systems, which rely on accurate speed data to function correctly. For example, collision alerts may not activate in time, adaptive cruise control may not maintain safe distances, and braking systems may not respond appropriately to speed changes. Furthermore, the driver display includes a light that indicates when the vehicle is exceeding the detected speed…”
