Can I ask a car dealership to exchange the brand-new car I got today, but had to return it because of faulty electronics?

I bought a brand new Honda Civic for my daughter, she went to the dealer today to get it. After driving for less than two hours she had to go back to the dealer. The car had electronics issues. Her speedometer was going from 35mph to 0 and so on. They said to leave the car and that they will try to have it fixed by this coming Monday. Legally what are my options? Can I ask them to exchange my car for another? Am I stuck with the car that I had to bring back to the dealer less than two hours after I got it? Thank you for any help you can give us
