At approximately 1,700 miles, my brand-new 2026 Ford Explorer st (3. 0l ecoboost) suffered a sudden, catastrophic engine failure while driving, causing an immediate and dangerous loss of motive power. Prior to the failure, the engine experienced severe misfires. Following manufacturer technical service bulletin (TSB) guidance regarding ecoboost engine misfires, a step-colder spark plug heat range (ngk ltr7ix-11) was utilized to remedy pre-ignition. Ford motor company has denied warranty coverage for this catastrophic powertrain failure, falsely claiming the TSB-compliant heat-range plugs caused the destruction. The sudden loss of engine power poses an immediate safety hazard on public roads. I request an investigation into 2025-2026 Ford 3. 0l ecoboost spark plug issues, pre-ignition failures, and unfair warranty denials leaving dangerous vehicles unresolved. ".
Bought the vehicle brand new on March 13, 2026, and the battery light came on in less than 200 miles driven. The vehicle is currently in Ford's possession.
