Hi - I need some help with an issue on my 2013 Altima 2.5 SV with 93k miles. A few weeks ago, the car seemed to have intermittent issues with accelerating at low speeds but radio/nav screen would turn off and back on. This lasted a few times then completely went away. About 2 weeks later, I drove the vehicle about 40 miles (interstate) and parked all day then got back on and it wouldn’t start. Had it jumped and it fired right up. I noticed the lights dim a lot when turning the wheel lock to lock when park and can seems to be easy and the very hard to turn (like power steering is cutting in and out). I turned it off after this and now no power to anything, can’t even lock the doors. I let the car sit for a while (1+ hr) then interior light will come back up but will not crank, immediately just blacks out or does nothing, just some relay clicking sounds.
Any help is appreciated!

Dead battery or alt.
