I'll say it's definitely not your wheels, inconceivable they would even suggest something so ludicrous. That implies to me they are incompetent or negligent.
3 cylinders are misfiring? I would first suspect fuel, then maybe the distributor. I would not much suspect spark plugs or ignition coils.

What brand of gas? Cheap gas, even with high octane, doesn't have as much detergent in it and can cause long term buildup.
I'd run top tier gas from busy stations (fresher gas). If you have been running Top Tier gas, inspect plugs, and other ignition components...

I had my mechanic check the spark plugs n according to him they are all good still even the coil packs he checked n they were good. My car has 64,000 miles n I've only used 91 gas. Idk what the hell is going on anymore..... Seems like an odd issue I can't pin point or the dealer😤

did you try
emptying the tank,
throw a walmart purchased bottle of chevron techron fuel system cleaner in, fill the tank 3/4 of the way with shell premium
or chevron premium
if you haven't tried it that should be your first line of defense
what i saw in video tends me to believe its a eco issue or a plug issue / coil pack but first one is cheapest to try

With other cars that I owned, misfires have been caused by a bad spark plug wire, bad ignition coil, bad spark plug, or a bad injector. The bad injector took me two months to isolate. The engine trouble codes might reveal more details.
