Alternator/generator/regulator problems of the 2016 Nissan Titan

On 05-01-2020 I was driving back home on I-59 north and I lost the power steering, alternator and a/c. I continue driving because I still have mechanical steering control I get home and I noted the serpentine belt and the belt tensiometer was broken, I ordered and changed after repaired I was driving to work on 05-07-2020 and I notice the car is not working good, I check and 1 of the bolts from the steering pump adapter was broken, I take to the dealer and after a week and be talking with Nissan case number 40163453, with the car inside of the warranty they say the bolt is a hardware and is not cover by the warranty, also the dealer say is going to be expensive repair because they have to remove the radiator, I choose to do the repair by myself, I'm an aircraft inspector with 39 years� experience repairing airplanes. I fix in the best way I know, but this situation can cause a accident see attach pictures, also the adapter pump holes are little big of the diameter of the bolts with the vibration of the engine (diesel) can cause this bolts to be loose.
