Loud Engine Noise problems of the 2014 Nissan Versa

Since purchasing the car in 2014. I had the body throttle replaced, the fan on the ac. Now the electrical motors for the doors to lock and unlock is going out. I truly feel when I purchased this car it was a lemon. Because I had only had the car for a couple of years when the dealership had to replace the throttle body and shorty thereafter, the dealership had to replace the fan on the ac. Now on 23 Feb 2020. I am on my way to church when I notice this loud noise and now I've been told the motor is going out that controls locking my cars doors. When the throttle gave out I was driving when I notice this loud noise. When the fan gave out on the ac, I notice that the ac no longer work and I attempted add freon and I was told that it was the fan on the ac. My major complaint today is the motor on for the lock/unlock. It's a shame that cars are only made to last a short period of time or at the lowest cost possible and the sell them for outrageous price over the fair market price. Sometime its just better to purchase a used car opposed to new vehicle that you think will last and but its not like that at all.
