Problems with new Santa Fe

48 hours, thats how long I've had it. Copper V6 Auto.
Cigarette lighter dead.
When I come to a stop at a light, then press on the gas when green, I hear a
thunk from the front left.
When I drive, come to a stop and put it in reverse, I hear a thunk.
When I go around corners, and hit a small bump, I hear the same thunk.

Other than that, previous hostile post by me notwithstanding (please spend
time in my shoes to see where I came from, thank you ), the car is good.

Oh, not impressed with night driving last night. There is no seal between
the rear window and the third LED brake light, so the whole rear window
lights up like red fire when I brake at night, causing bright glare in the
rear view window.
But again, aside from that, I like the car.

Oh, and the radio doesn't have scan, only seek.
Going back to the dealer next week to fix differential and lighter problems.
