car has less than 13 k miles. car sounds funny like has muffler issues. sounds deeper exhaust. like muffled in a way yet more deeper sounding. Not as much power.
It’s still covered by the 3 yr/36k mile “bumper-to-bumper” warranty, so you should have the dealership look it over.
Didn’t tell us what engine, what transmission What “funny” means to you. If this just happened or if its always done this… So I will take a wild donkey GUESS!
You broke the exhaust open running over something.
