Hyundai sold me a faulty car

I bought a Hyundai venue in December 2023 and ever since I bought the car it has been fivi5me power failure fault so in January I sent the car for repairs at their workshop and they allegedly fixed the spark parks however till today the car is still giving me problems and they are insisting on fixing the car again why should I be fixing a car every other month that I have recently bought? And the manager Anton very pathetic service and stated that my issue was not serious for a different recourse so I should constantly be sending the car to the workshop I am so disappointed and I will take this matter up with the ombudsman
