NHTSA Complaint #11712392 — 2024 TOYOTA COROLLA

The 2024 Toyota Corolla needs to be added to the list of vehicles currently being investigated for transmission/engine issues. The vehicle in question is currently exhibiting transmission anomalies consistent with those observed in several other vehicles under review, specifically: slipping, jerking, surging forward, hesitation to accelerate from a complete stop, loss of power, droning sound at low speed, odd knocking noise/vibration during idle, unresponsive gear changes, shuddering upon vehicle shutdown, and decreased fuel efficiency. The owner has incurred expenses exceeding $2,000 for rental vehicles and diagnostic services in an effort to resolve these persistent issues. However, as of January 21, 2026, Toyota has not acknowledged the existence of a problem, asserting that these conditions are within normal operating parameters and that the vehicle is performing as intended. A local mechanic has advised the owner that Toyota will not diagnose the issue, but they are likely to offer a post-warranty adjustment should the transmission ultimately fail. It has become increasingly apparent that Toyota is not conducting a thorough investigation into these matters and expects the customer to bear the expense beyond the scope of the standard warranty. Beyond the immediate safety concerns for the owner, there is a significant risk of collision should the vehicle experience a loss of control or erratic behavior. Thank you for your time and assistance in investigating this matter.
