Cancelling a car purchase and claiming refund for hidden defects

Hi,

I financed a car from a second-hand dealership in Sharjah. The car is a 2018 Mustang GT! They said the car was fine and had no accidents, it looked fine too.

I took the deal and even had a new car screen put in through the dealer for AED 2000. The car has given me problems from the first month. Hazard lights would come on and kill the battery.

The dealer told me to give the car to the garage, so they took the car and said a new screen is needed and they made me pay AED 1000 even though it was not my fault.

I even paid to have the car delivered there but I paid out of the goodness of my heart. Next month it started dying randomly and would need jump-starts. Now it dies every day after a jump start. Now they are saying to me I need to pay for another fix!

Please can someone tell me what to do?

Is there any legal way they can take the car back and pay the bank back the money they took?
