NHTSA Complaint #11672073 — 2020 FORD F-350

Our 2020 Ford F-350 experienced a catastrophic mechanical failure while in motion. The driveline disconnected, the rear axle locked up, and the transmission bellhousing was destroyed—leaving the truck completely immobile and blocking traffic. This occurred with no prior warning and posed a significant crash risk. At the time, Ford Safety Recall 22S22 (related to a known defect in the transmission’s output planetary four assembly) was open and had not yet been completed. The symptoms and failure we experienced match the failure scenario described in Ford's own bulletin for 22S22: driveline separation, internal transmission damage, and loss of control or Park function. Ford has denied coverage, stating the failure was due to a "loose pinion flange nut" and unrelated to the recall. However, they have not provided any inspection documentation, photos, or evidence that the recalled components were properly inspected or ruled out as the root cause. We have repeatedly requested this documentation from both Ford and the dealership, but neither has provided it. We are concerned that the failure was caused by the exact defect identified in Recall 22S22, and that Ford is failing to take responsibility or follow full recall procedures—including post-failure inspection and transparency. We are requesting that NHTSA investigate this case as a potential mishandling of a known safety defect and failure to comply with recall responsibilities.
