Yes...Get rid of it.

The car is clearly a lemon and dangerous. Next thing we will hear is it accelerated on its own or the brakes have failed.

The dealer seems like they are trying and may be open to simply do a Trade Assist. 30 days and more than three service is usually all that is needed for a lemon
