Bad tire? Rotate and see if thumping changes
A thumping noise on your Hyundai Sonata that accelerates when you go faster might be a tire balance issue or a tire that is coming apart. You might also have an issue with the tie rods.
Have that tire checked sometimes the belts inside can break and cause a thumping noise
The road might be very bumpy or might have big pebbles on the road.
A busted motor mount, for one.
I think i can help; where are you from?
The driveshaft might be out of balance or dented in some way, also check the u joints
Bass
It sounds like wheel bearings. They make a noise while they're in one position but when you hit the brake, it moves them a little, and the noise stops.
Maybe that thumping noise is the sound of another car smashing into the rear of your car.
Take it to the garage and have them check for a cracked rotor or a loose caliper.
Have those two front tires checked out there might be a bulge or a broken belt in the tire.
