2020 Volvo S60 Suspension Problems

It is unknown what caused this issue but ever since I bought my vehicle on April 5, 2021, I have been experiencing vibration issues when driving between 65-75 MPH. I have had my vehicle inspected at multiple Volvo Service Centers across Texas and no one can seem to figure out what is causing the vibration issues. My front rotors have been replaced 3 TIMES, my rear rotors have been replaced once, I have had multiple tire rotations, alignments and balancing from Volvo Service Centers and even from Discount Tire. With all of these items serviced/repaired/replaced, the vibration is still present in the steering wheel traveling at highway speeds. I went on a test drive today, 6/22/22, with a Volvo Service Technician and he confirmed that the vibration is valid. He also stated that the only thing left to do is to replace all 4 tires, at my cost, to see if the vibration goes away. He advised that when new cars are on the lot parked waiting to be sold, dealerships typically inflate the tires to about 50 PSI so as to avoid any "flat spots" on the tires. He also stated that many dealers also typically do not inflate tires on their new fleet due to the rough ride it causes. I have contacted Volvo regarding this issue without any remedy or advice. Additionally, my Volvo dealer cannot say for sure that they will reimburse me for tires, if I do choose to replace my current ones, even though this issue has been present since day 1.

Ongoing Problem as mentioned in Volvo's Technical Journal "Speed Dependent Vibrations at Highway Speeds" Ref No: TJ 20803.20.0 . At any speed of 75 mph and above the front continuously vibrates. The tires have been replaced two times in less than 2 weeks and road forced balanced by the dealership twice. The vibration does not go away. The dealership does not want to address the issue. The car is NEW.
