Good Afternoon. The Pro Power Onboard high-voltage electrical system has experienced a permanent malfunction, locking out with a "Ground Fault Detected" warning. The vehicle is a 2021 Ford F-150 Rocky Ridge conversion. This failure stems directly from a defective or incomplete execution of Safety Recall 23S35 (NHTSA Campaign 23V613000).The initial remedy applied by the dealership consisted only of adding protective tape to the rear wiring harness. However, due to the increased travel and ride height of the official Rocky Ridge suspension lift, the wiring harness pulled out of its factory retaining side clip. This caused excessive tension and stretching on the high-voltage lines, completely exposing the bare interior colored wires and leaving them vulnerable to road moisture and friction against the metal frame.The system now triggers a permanent short-to-ground error, creating an imminent risk of an electrical short circuit or vehicle fire under the high-voltage (120V/240V) lines. The Ford dealership and corporate customer care refuse to remedy this recurring safety hazard under the recall warranty because it was previously marked as completed, even though the applied remedy failed to safely secure the harness. The component is available for inspection.

The driver's side rear axle bolt sheared off over the course of normal driving. Ford is aware of this problem, advises to not use/drive the vehicle, yet no recall has been issued. Without a recall, getting this issue fixed will take weeks/months and Ford should pay for a rental vehicle since this is clearly a manufacturing defec…

Leaving me with a bad wheel bearing that I consider prematurely worn out and is making a clicking sound. Dealer says they cannot r…

Very loud grinding sound coming from the rear axle/ wheel hub area. Then a clunking as if something was loose or rattling around inside the rear hub. Turns out the axle bolt has sheared off.
