I bought new 2024 Lincoln Navigator in March 2025. From day 1, the vehicle rattles and vibrates above 40mph. The vibrations are high pitched and lead to whole car shimmering. I had all four tires and wheels replaced by the dealership. The vibrations are significantly intense when compared to normal road feedback. The vibrations lead to excessive fatigue and tiredness over long distances travel. Lincoln has issued service bulletin and no fix has been found so far.
