My 2018 CRV is a few months shy of three (3) years old. Went to start it a few days ago, and had every warning light go on - bells and buzzers alarming, and then click - car would not start. Long story short, put new battery in, and car started fine and has been OK since then. Battery was OEM Honda. The next day, I checked voltage on the old battery - 11.90 VDC - more importantly - there was little-to-no water in cells. I know I should have been more diligent in car maintenance. We've experienced a very hot summer and the CR-V tends to run very warm. Would appreciate some input- does the vehicle need checked over by Honda - or is this a dead or poor condition battery issue? thank you. (the vehicle has 41,000 miles).
