NHTSA Complaint #11474101 — 2016 HONDA PILOT

When the auto idle stop is not disengaged (the default setting when the car starts is that the auto idle stop is engaged), the car will sometimes not restart when the idle stop occurs. It's unpredictable and scary, especially when it occurs at a light or in stop-and-go traffic. The dashboard lights up like a Christmas tree, and there is a clicking noise. I have to place it into Park, shut off the engine fully (it's not running - I think it's in Accessory mode), step on the brake and restart. Because of this, I make a habit of disengaging the auto idle stop when I start the car. Unfortunately, sometimes I forget to disengage and this engine restart failure happens. I have read that an old/weak battery is suspected. This is not true in my case. This issue has happened several times after I changed the battery on 12/15/2020. Interstate MTX48/H6 battery at $300. It's not just me - it has happened to my wife, and my 17 year old son, when driving this car. At first, I thought my wife did something wrong, then it happened to me. In total, I'd guess it's happened > 6-7 times. We try to be careful to push the button and disengage the auto idle stop. But you have to do it EVERY TIME YOU START THE CAR. If you forget or are distracted, then the problem can occur.
