Ford basically told me to pound salt. After multiple attempts to fix the problem they decided that the problem is now acceptable. Here is what the Ford Feild Service Engineer said:
During my visit today we test drove a 2022 Navigator vehicle along the same route we took the clients vehicle on my last visit. During said drive, we were able to duplicate a vibration at 72MPH. I took readings of the vibration on my Electronic Vibration Analyzer, and then hooked up the same analyzer to the clients vehicle, and we took the clients vehicle long the same route. At the same speed along the same route we were able to duplicate a vibration on both vehicles which had an amplitude of 0.020 and a frequency of 12.5- 12.75 Hz. These readings matched the readings we obtained on a different 2022 Navigator vehicle on my last visit.
In the Ford Workshop manual for the 2022 Expedition, under Vibration and Harshness Diagnosis and Testing, indicates that a vibration with an amplitude under 0.06Gs is acceptable, and no corrective action is necessary. Given this, and the fact that we found 2 different like units equipped with the same size wheels/tires which exhibited this vibration, this would indicate that the vibration noticed by the client would be considered an undesirable characteristic of the Expedition/Navigator model line when equipped with 22’ wheels. At this time, no further diagnostic steps or repairs are recommended.
I am now in the process of requesting a buy back from Ford. If they do not buy it back I will get it bought back with New York State Lemon Law.
