My 2017 Hyundai Sonata has been feeling like its losing power when I'm driving at higher speeds (over 50 mph) and when the ac is on it worsens and you can feel vibration in the car which feels like it's either coming from the engine or tire. I can feel it beneath my gas pedal but it doesnt go away. Feels like the car doesn't want to go over 65mph. I had a mechanic check out the ac system but found nothing. Does anyone know what the cause could possibly be? I have about 65,000 miles on the car.

Did you tell the mechanic all these symptoms? Or just tell him to look at AC?
You need to tell him everything. If you have then you need a better mechanic.

I would check battery voltage with AC on and fuel pressure.
