NHTSA Complaint #11663792 — 2022 FORD F-350 SD

1.Spark Plug Wire Failures: oIncident 1: On December 15, 2024, a spark plug wire failure on cylinder #1 caused a misfire and check engine light (code P0301), reducing engine power while towing a 10,000-pound trailer on I-90. Wendle Ford Spokane repaired it under warranty. oIncident 2: On April 10, 2025, another failure on a different cylinder triggered a misfire and check engine light, requiring a $766 repair (invoice attached). These failures are a known defect in 2020–2022 Super Duty trucks, per owner forums and a 7.3L motorhome Technical Service Bulletin. oSafety Risk: Misfires reduce power and control, endangering occupants and other drivers, especially during heavy towing in winter conditions. 2.Front Differential Failure: oOn April 5, 2025, the front differential failed, disabling 4x4 throughout the 2024–2025 winter. Discovered during a snowstorm on a rural job site, the loss of 4x4 compromised traction and stability, requiring a one-week repair. oSafety Risk: Loss of 4x4 in adverse conditions increases the risk of skidding or stranding, particularly for a heavy-duty truck used in construction.
