The warning screen keeps randomly popping up, but just says, " Warning Review" and below it "No items to review". There are no other specific warning lights that come on. I guess that's just the basic warning screen when there aren't any problems, but why does it keep popping up randomly?

 

Look in the 2016 Nissan Maxima Owners Manual, page 2-16 Instruments and controls and the next few pages. This explains how that system works.

 

I'm not finding anything in the manual specific to this, but I am sure at this point, that the battery or alternator is bad. There's a slight hesitation from normal when starting the car and the battery reads 10.4 volts. It's the original 8 years old battery, so it's getting replaced and I'll go from there. I didn't know about the hesitation when starting before, as it's not my car, hopefully it's just the batt. Thanks for the reply, RickSmith.

 

This is from the manual, page 2-16 and 2-17
