The moonroof drain hoses are not secured and is known problem with other Navigator and Expedition owners. I became aware while troubleshooting why the liftgate would not open. The procedure to access the Rear Gate Trunk Module (RGTM) requires the removal of the 3rd row seats, C & D pillars and several cabin panels. After the removal of these items I noticed the insulation under the carpet and behind the panels were drenched. The Reserve trim on my Navigator has very dense carpet and a backing that does not let the moisture evaporate over time. Rather, it retains water almost indefinitely. Upon removing these items and the front row kick panels, I discovered the water was 3” deep. Because of this leak, the water submerges numerous wiring harnesses throughout the cabin that affects nearly all computer modules. It is also the root cause of my liftgate not opening issue. Per the 2018 Lincoln Navigator/Ford Expedition Electrical manual, there is a splice of the VBATT Always Hot wire under the front drivers kick panels. Despite the factory shrink wrap, water penetrated this splice and corroded the copper wire resulting in an open circuit. I repaired the wiring and solved the liftgate issue. I also went thru the painstaking process of remediating the water damage. Of bigger concern, is the amount of corrosion on other wiring connectors and splices that is unknown at this time. I believe this defect is a safety hazard of unknown proportion given the various modules dependent on the submerged wiring. There is also a health concern of mold growing due to the carpet backing not permitting moisture to evaporate. On the cosmetic side, there visual water stains on all four sides of the headliner. When I reconnected the right rear failed drain hose, I secured it with a tie wrap. I believe Ford should take ownership if this defect and use tie wraps to secure all 4 drain hoses at no charge to mitigate the damage and health impact.

The back up camera will randomly black out. The steering wheel motor is broke and the steering wheel does not adjust. Needed a new air conditioner motor, timing chain, had a transmission leak, wheel axel leak. This is a safety hazard and caused a huge financial strain.

The side mirrors, which are power adjusted, either will not properly adjust to the same setting when they first fold out when you start the car, or they will start moving when you start driving. This happens nearly every time the car is started. I have talked to fellow Ford F-150 owners who have the same problem. This causes a serious safety concern, especially when they start adjusting as you start driving because then you cannot safely see any obstacles beside the car and the warning light if someone is beside you does not work effectively. If I start my car and go to back out of a parking spot or driveway and the mirror start adjusting so suddenly I'm looking at the pavement instead of what is beside me, you can see why that would pose a safety concern to myself and anybody who may be passing by.
