My car STAYS at the DEALER

This is frustrating. My car is at the dealer for the 4th time, with the same warning sign. I have paid twice, and expect to pay again when it is back.

The car is returned to be, I drive, few days later it is taken back and stays two weeks. So on and so on.

Two things are frustrating me (1) I keep paying (2) They can't even give me a loan car. They say they don't have one, which is unlikely. This is a franchise dealer and I am sure they can make a plan to get me a car. Schools are open now, I uber my son to school daily, and Uber myself to work too. I have had to do AVIS rental three times, and it's just as costly as fixing my car.
