Lincoln MKX undercarriage noise from flapping insulators at speeds over 60mph on Lincoln MKX

Some Lincoln MKX owners report experiencing undercarriage noise, particularly a flapping sound at speeds over 60mph, which may be due to loose floor pan underbody shield fasteners that can cause rattling while driving. Additionally, debris or trash lodged under the vehicle, such as rocks or leaves, may contribute to these noises, especially during turns. To address the issue, owners are advised to check for any loose or damaged underbody shield fasteners and inspect the undercarriage for debris that could be flapping against the car's components. Promptly resolving these concerns can help eliminate the source of the noise.
