It might be "frame beaming" if so, you are stuck with it

Luis, if you suspect that there is something wrong with the vehicle then I would suggest that you have the vehicle checked out by your local dealership. They would be able to make sure that there isn't anything wrong with the vehicle or fix it if there is. I hope that helps you. If you run into other issues please feel free to contact me.

Check the tires, maybe they are over inflated. Seen that happen before.
