Several times, all of the lights would flash on the car to check all of the systems and then the car would shut off while I was mid drive mostly while in a residential neighborhood but sometimes on a major parkway. After about an hour the car would start back up. I would not be able to start the car or change gear while it was shut off. I had the battery and alternator checked and that was not the problem. I took it to the repair shop and they said it was the fuel pump. I researched online and saw several 2015 Acuras were recalled with this issue but not my VIN number. I have pictures that I took when it was last flashing if that would be helpful.
Agm battery failure every few months. Suspected cause is constant undercharging from computer algorithm that limits alternator output to battery. This situation is worsened by idle-stop feature that requires deep discharge from battery. Idle-stop cannot be disabled. Dealership cannot cope with this problem. American Honda has offered to provide an overnight charger that plugs into house power. Otherwise they accept no responsibility for a design that cannot keep the battery charged. The result is a $40,000 luxury car that leaves you stranded. This is a serious safety problem when it happens in traffic. Other reports on the internet indicate this is not an isolated problem.
