2026 Toyota Corolla

I own a 2026 Toyota Corolla purchased in November 2025. The recurring problems began on December 8, 2025, when multiple warning lights appeared on the dashboard along with the message “System Malfunction – Visit Your Dealer.” The warning indicators involved several vehicle safety and driver-assistance systems. The vehicle was taken to an authorized Toyota dealership for inspection and repair. On June 16, 2026, the vehicle experienced another serious malfunction, including a “Transmission System Malfunction” warning. The electrical and operational problems continued despite dealership visits and repairs. The battery was also replaced, but this did not permanently resolve the recurring failures. During a later incident while the vehicle was being driven, multiple warning lights appeared and the vehicle lost power or shut off. There was no crash or injury, but the unexpected malfunction while driving created a serious risk to the driver, passengers, and other motorists. The dealership has also addressed an issue involving the shift lever position sensor and corrosion or water intrusion. I do not know the exact component responsible for all of these failures. However, the problems have occurred repeatedly since December 2025 despite multiple dealership visits. Toyota was notified and corporate Case No. 260630000224 was opened. I have not received a permanent explanation or resolution, and I am concerned that the vehicle could unexpectedly malfunction or shut off again while being driven.
