Purchased a 2014 Accord touring (3.5L, V-6) and battery has died twice. If it sits longer than 2 days without driving, I need to charge the battery. Even with a full charge, when I push the "Start/Stop" button, it sputters and cranks very slowly, and will eventually start. This is my first Honda and a I purchased because of the supposed superb reliability. Needing to charge the battery every 2 days on a car with 400 miles is ridiculous. Anyone else seen this issue or have any ideas??

 

You must be under warranty. Take it to Honda. Occasionally, a new battery will fail early for many reasons.

good luck
