NHTSA Complaint #11561903 — 2015 FORD F-150

Vehicle has a catastrophic design flaw. If water enters the LED BLISS tail light assembly even in small amounts for anreason, including due to manufacturing defects, minor damage such as a crack, e treme wet weather, or wear and tear of seals, then numerous electrical failures occur of the entire warning system. This includes not only the tail lights, and blind spot backup and cross traffic systems, but catastrophic failure of all dashboard door and window controls. The vehicle cannot be easily unlocked including with remote, climate and accessories cannot be controlled. They vehicle can barely be operated and great expertise and expense required to return the vehicle to proper service. This has happened twice to this vehicle in 2022. Both times it was from minor damage to the taillight lens. Water entered the connectors for a network system which is critical to numerous vehicle safety and critical systems which are completely digital. The part required replacing is available only from a dealer as an OEM part and cost $500 plus labor. Research shows this is a widespread confusing problem, which renders high end models nearly inoperable with uncontrollable systems other than basic engine functions and subjecting consumers to great inconvenience and expense. The manufacturer does not appear to have offered recall services and only will repair or replace if the item fails under warranty. Under any interpretation this problem is a gross failure in engineering and safety. What other vehicles with a minor taillight problem have failure of a majority of systems? So many codes are thrown that the average technician and consumer must bear great expense to repair for diagnosis, and then replacement with extremely expensive parts only available from dealer.
