Dealership Responsible: Ted Britt Ford of Chantilly Dealership Address: 4175 Auto Park Cir, Chantilly, VA 20151 Complaint Details: I purchased a 2018 Lincoln Navigator L Black Label, and since then, I have experienced multiple serious mechanical failures due to an improperly performed cam phaser repair by Ted Britt Ford of Chantilly in 2020. The dealership-??s service department performed a faulty installation, which resulted in: -??Missing and broken screws in the cam phaser system -??Jerking, rattling, and acceleration issues -??Significant engine damage requiring a complete short block replacement As a result of this in negligent repair, In 2024 I had to replace the cam phaser again, along with replacing the short block of the engine due to the extensive damage caused by the dealership-??s poor workmanship. In addition to this issue, I have faced multiple other failures, including: -??Valve body replacement -??Wastegate failure -??Rear heat stopped working -??Steering column failure These problems have caused frequent breakdowns and safety concerns, making the vehicle unreliable. The constant need for repairs raises serious questions about the quality of Lincoln-??s engineering and service network. This issue is not an isolated incident, and I strongly urge NHTSA to investigate potential defects in the 2018 Lincoln Navigator and to hold dealerships accountable for performing unsafe and defective repairs. Requested Action: I request an investigation into the faulty cam phaser repair process and whether similar issues are being reported by other 2018 Lincoln Navigator owners. This could indicate a larger systemic defect or a trend of poor-quality repairs in Ford/Lincoln service centers

Started vehicle and went to adjust steering wheel I pushed the down button to lower and steering wheel dropped. Steering wheel is no longer able to adjust up or down only forward and backward. When pushing the up/down button a grinding sound occurs. When driving steering wheel feels loose and will pull to the right.
