What 236 owners told NHTSA about the 2021 Ford F-150 (super Crew) Hev

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 Axle bolts on both sides of the truck sheared off. The passenger rear axle bolt sheared at 15,000 miles into having the new truck. The driver side rear axle bolt sheared at 21,000 miles. This is a large safety concern and is not unique to just me. The first axle bolt sheared and was repaired once I figured out the problem at a Ford dealer. The second bolt is currently being repaired in the same dealer's service department. There was no warning or detection of this problem other than a rattling sound during acceleration and a wizzing sound during braking. I do not have either of the sheared axle bolts. They were kept by the dealer.

Active Air Dam: My 2021 Ford F150 XLT truck has an active air dam, (AAD), that is suppose to move downwards at speeds of 40mph or greater to help with aerodynamics. This is to help the truck hug the road better at highway speeds. When the truck slows down to under 40mph, the AAD is suppose to recess back up an be tucked away behind the stationary air dam. They started these AAD's on their trucks in the model year of 2021. It has been a widely known issue that the AAD design is flawed and they malfunction and get stuck on the front air dam. Some have came loose and flown off into other vehicles on the roadways. This presents a safety hazard to the owners and other vehicles on the road. Ford refuses to fix it stating that their extended warranty does not cover the parts. This is NOT a warranty issue, this is a poor design issue and a faulty part issue that is going to cause someone to get seriously injured or worse, killed. Some people have reported that their AAD flew off their truck and they didn't even notice until the service tech at the dealership told them during an oil change. So that means their are people out there that are driving with this hazardous part flying off their truck and where is it going? Into the traffic following behind, and what are those drivers going to do when it comes hurling at them at a high rate of speed? Most likely slam on their brakes, causing a rear end collision, or they serve to avoid it and either hit an on coming vehicle head-on or slam into the vehicle next to them on a multi lane highway or interstate. Please make Ford fix their problem before someone gets killed or seriously injured.

The drivers door lock sticks in the cold, so it will occasionally lock me into or out of my vehicle. I feel this is a safety issue, because I may not be able to exit my vehicle quickly in an emergency situation. It also may not lock leaving the vehicle vulnerable to theft.
