| Engine And Engine Cooling problems |
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. ".
While driving my new Ford Explorer, with 638 miles on it, on the highway I heard a loud pop, and lost power steering. I was barely able to pull the vehicle over to the shoulder to get off the highway. If I would have been on an interstate or a busier highway it could have been very dangerous. I believe that this has put me in danger having to maneuver the vehicle to the side of the highway and sit there while waiting for a tow truck. The vehicle was towed to the dealership where we bought it. The service manager told us that the engine had blown, it was a catastrophic failure. There were holes in the oil pan as well as through the top part of the engine from it exploding. I believe that we are lucky that the engine wasn't hot enough to start a fire, as we were only a few miles from the start of our drive. There were no warning lamps or messages prior to the engine exploding. The vehicle is currently at our dealership in monroe wisconsin, alphorn Ford is the dealership.
