Dear Doctor: When I parked my 2018 Honda Accord and returned to start it, everything was completely dead. The only thing that showed any life at all was the blinking push start/stop button, yet pressing the pushbutton failed to start the car. After the battery was boosted, the car immediately started and everything returned to normal. No warning symbols appeared on the dash, and the problem has not occurred again since then. I hesitate to bring it in to Honda since it seems to have been a singular event and the car has had no other problems. Do you have any ideas on what happened, why it happened, and what do you suggest I do now? - Bruce
Dear Bruce: There is no reason not to take the car to the dealer, as it's under warranty. They will run a check of the battery and charging system to make sure nothing is wrong with it. For the battery to go dead as you described means something must have been bringing the battery voltage down low enough to have prevented the starter from cranking the engine over, or the connection at the battery was poor.
