defective Nissan magnite

I purchased a brand new Nissan magnite in August 2021 and since the first week I have had endless problems with the vehicle, now I have owned it for a year and a half and I am still experiencing problems with the vehicle, the dealership I purchased it from is always willing to help but enough is enough, all the inconvenience of. taking leave from work and traveling to the dealership is not acceptable something needs to be done, highly dissatisfied with the product and I must not be accepted to keep a defective product which I am paying for, I have had problems with the engine, radio, seat belt, tire pressure monitoring system among other things and I am fed up of running up and down to the dealership, something needs to be done as soon as possible!
