NHTSA Complaint #11716506 — 2016 FORD F-150

Our 2016 Ford F-150 experienced a sudden, forceful, uncommanded lane deviation while traveling at highway speed. Without warning or driver input, the vehicle abruptly jolted into the left lane. The steering was corrected and returned to our lane, but shortly afterward the truck again forcefully veered left. The movement felt comparable to being struck by another vehicle. There was no oncoming traffic at the time; however, had there been oncoming traffic, this would have resulted in a head-on collision. Weather conditions were calm, roads were dry, and visibility was clear. Prior to this incident, the vehicle exhibited no warning signs, including no pulling, steering issues, warning lights, or diagnostic codes. We immediately pulled over and had the vehicle towed to a mechanic who inspected the truck but could not replicate the issue. Although the vehicle was later driven approximately 120 miles home and short distances locally without recurrence, we believe it remains unsafe due to the unpredictable nature of this failure. A vehicle should never abruptly and forcefully change lanes without driver input. We have also experienced ongoing issues with the key becoming stuck in the ignition and intermittent starting problems, raising concerns about potential electrical or mechanical defects. This incident involved two uncommanded lane deviations under normal driving conditions with no identified cause or warnings. Due to the risk of serious injury or fatal collision, this remains an unresolved safety concern requiring investigation. We are requesting that NHTSA review this complaint, evaluate whether similar incidents indicate a pattern or defect involving the steering, transmission, or electronic control systems in the 2016 Ford F-150, and take appropriate action to protect public safety. Once we receive the NHTSA complaint number, we will also be submitting a formal complaint to Ford Motor Company requesting a thorough investigation and resolution.
