My battery died on the new gen QX50 while I was on a weekend trip so had to make it work until I could get home to swap it out. Literally two days after I bought the car lol!! Luckily had a portable battery jumper so never got stranded. However, I can definitely tell you I would highly recommend not driving the car on a weak battery from my experience.

The car has so many electrical systems that it appears the alternator itself struggles to handle the load if the battery is compromised. I would get random error messages as various systems failed. The worst is the power steering would fail too so sometimes when you turn the steering wheel, the actual tires doesn’t turn and the steering wheel just clicks. Not surprisingly it threw a check engine light as well. Anyways, got home, swapped the battery and everything went back to normal. Or so I thought.

I did notice the ProPilot Assist feature was slower to engage, and would drive too much to the right or bounce from line to line. At times it would fail to slow down enough when traffic slowed without intervention. There was even times when the car in front was braking and my car would decide to accelerate, all while beeping at me warning of an imminent crash lmao. It would also follow so closely sometimes and instead of easing on the brakes it would brake hard then accelerate hard to catch up again. I had suspicions that my battery fiasco threw off the ADAS calibration but was unsure since I only had the car two days before that happened so I took it to Infiniti and asked them to recalibrate it. They told me it was working normally so I just chalked it up to being the limitations to level 2 self driving.

8 months go by, I recently caught a huge crack in my windshield and had to get it replaced. In order to complete the job they had to recalibrate the ADAS system. Holy moly, the difference is night and day. I can actually trust it in traffic. The car stays centered in the lane, accelerates and brakes so much more naturally and is no longer trying to kill me lol. Now I understand why so many people are saying Nissan/Infiniti has a fantastic ADAS system. Definitely is one of my most used features in the car.

Long story short, don’t drive your car on a compromised battery or a lot of weird crap will happen. Infiniti told me the ADAS system either works or it doesn’t so if I was able to engage it then the calibration is fine. That is NOT true! The calibration was messed up and it would still engage in my case. In conclusion, Hopefully someone can learn from my better lack of judgement haha!

You’ll probably be fine. My battery was fully dead. I had to jump it every time I turned on the car. Crazy I bought it at a Nissan dealership and they knowingly just charged it up and sold it to me like that. When I complained, they said oh well, too bad! So I had to pay for and install the battery myself. Never giving that dealership any business again. Lol

Gentlemen....I had a 2018 Armada that had the same issues with the battery. The vehicle starts fine and then you drive it to your destination, go to start it again and it would be almost or completely dead. The problem is that if the computer thinks that the battery is full, it stops charging it. This is apparently an idea of theirs for better fuel economy ! So the issue is in the communication I believe from the ECM to the battery. The negative cable from the battery had a module on it that some guys had eliminated which somehow stopped this from happening. Now obviously, Nissan and Infiniti would share how they do things so I would bet that is the issue. The dealers should be familiar with this as it was a problem with Nissan products. The dealership replaced the battery and for the time remaining that I owned the Armada, it was fine. I may not have explained it all properly but I hope it helps. Cheers.
