Dealer service departments have repeatedly replaced failed tires without diagnosing or resolving underlying suspension clearance, wheel alignment geometry, or mechanical defects causing these recurring structural failures. During an October 14, 2026 service visit, dealership staff refused to answer technical…

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 âSystem Malfunction â Visit Your Dealer.â 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 âTransmission System Malfunctionâ warning. The electrical and operational problems continued despite dealership visits and repairs. The battery was also replaced, but this did not permanently resolve the…
