Yes. ICE used to come online what almost seemed like every other day. Ever since I used normal driving mode, no unexpected ICE. The only time it kicked on was when I floored the accelerator. Engine will kick on even before the kickdown.

Ken said he drives in Econ mode and JCE rarely comes online.

Should I pursue this issue or just say "I love Big Brother!"?

I’d like to make a comment on the poll. It seems a little over half of us are reporting their ICE has never started unexpectedly. After installing an hour meter under the hood and noticing that there were times the ICE had run and I didnt even hear it, I started watching rhe HV range. I drive all EV local under 50 miles so I didn’t notice at first that it would decrease by a few miles about once a month. Then when it did I popped the hood and found hour meter had gone up 0.1 and the exhaust manifold was warm. And one time I caught he engine running and knowing it was on, could just barely hear it inside while parked and couldn’t at speed.
So I am going to speculate that the 51% reporting no ICE may have actually had some small amount of engine running for System Checks and just may not have heard it running.
If so, it’s a testimony to how quiet the engine is at idle and how well Honda has isolated the interior from noise.

I am sending an email with my case number every day I drive the car. Maybe they will get annoyed enough to do something.

This is the Clarity TV ad. Notice there is no mention of the ICE coming online while the battery is charged fully. On the contrary, it implies that the ICE will come online AFTER the battery is depleted.

It can’t really address everything in just 30 sec and I think the intent was to show that there is no range anxiety as in a pure BEV.
And the manual does state on p13 the 5 scenarios where the ICE will turn on and even stay on.
So even though we don’t have a pure EV mode we can force the car into, with a very small amount of effort we can drive it in 40 to 60 mile hops as a virtual BEV with neglible ICE usage.
But that doesn’t mean you’re not having a problem with excessively frequent ICE operation compared to what the rest of us are experiencing.
Still rooting for you!

So when it feels like it.

Have you estimated how much you are spending on gas by ICE coming on when it shouldn’t?
bobcubsfan

Very little. But that is not the issue.

I guess that’s out as part of an argument since the other ones you posed were basically rejected by Honda.

Yep. Honda does not think anything is wrong.

Have experienced this about once every other week and usually when the EV range is above 50 miles. Lasts about 3-5 minutes and then the ICE shuts down. It is a puzzling issue but one that I’ve begun to ignore as I feel at some point I’ll have to run the car in ICE mode just to use up the gas so it isn’t completely stale. By the way, how long should we keep a tank of gas in a car? Shouldn’t we be using at least half of the 7 gallon tank every 2-3 months?

Bob,
I think the only good thing is that you have the car on lease and get to return it after a while. My car would turn on after a full charge but the occurrences where few and far between. I suggest this to give you piece of mind. Consider buying this wifi smartplug (2 for 20 bucks):
https://www.amazon.com/Outlet-Compa...=1532228701&sr=8-3&keywords=teckin+smart+plug
Tested it and the power delivery of the 120v 16amp charger that came with the car and even a 120v 20amp charger are well within its safety rating. If you have the stock charger, you will gain 7.00% SOC each hour. If you have a 120v 20amp charger, you will gain 9.85% SOC per hour. These percentages added are during the warm months of the year. Goal is to charge to 90% or 95%. So if you have the stock charger lets use 10.00% for easy math. If you are at 40% SOC when you get home and you want to get to 90% then that is a 50% difference. 50% devided by 10% is 5 hours. Add another 2 hours on top. Either set the schedule to turn on automatically and then turn off 7 hours later or simply plug in the charger, turn on the smart plug (either through the app, or on the plug itself) and set the timer to turn off 7 hours later. Setup of the smart plug is easy and you can control everything from the app. App gives you real time watts, amps and volts and also daily and cumulative kWh used. Once a week charge to 100% so that the BMS can balance the cells. If you don't go above 90% or 95% your ICE should never come on. Manually turn it on once or twice a month to keep everything lubed (if your weekly full charge doesn't make it come on).
Try it out if you want and let me know if you have questions. Think it might give you some peace of mind.

Here is a link to a thread on this:
https://www.insideevsforum.com/comm...n-gas-stay-in-tank-honda-response.2534/page-2
Note that I am a proponent of adding Stabil to the tank since I drive almost exclusively EV and just went 4 1/2 months on the tank filled by dealer at purchase. I think that is prudent if you’re not doing a significant amount of HV and the gas sits in the tank for a long time. BTW, I’ve seen estimates of gasoline life range from 1 month to 1 year, so who knows for sure?
Certainly, the closed system of a modern automobile gas tank will keep gas longer than the plastic more tank in the garage, but loss of the higher volitive components and condensation can cause sludge to build up over time.
It’s a judgement call, but I add Stabil if my gas is going to sit in the tank more than 2 months.

What is the purpose of the monitoring plug? We have a 240 Blink for charging the car.

Perfect, then you don’t need anything else. I assumed you were using the stock plug. Is your blink a 240v 32a or 240v 16a. If it is 240v 32a you will get 42.5% charge per hour (in warm weather). Set your schedule so that you land between 90% and 95%. That should stop your unexpected turn on’s for good.

It is 32 amp, I think. If car is almost completely depleted it takes about 2.5 hours. Now, I don't see a percentage option for charging. Only When Battery is Full or Select End Time. By the way, if the car is plugged after the start time, it will not charge. That is a defect in the app or onboard timer. Our Leaf would start charging immediately if plugged in after the start time.

In the user manual on page 15 I found this:
When the High Voltage battery is sufficiently charged, the vehicle is propelled solely by the electric motor. When the remaining power of the High Voltage battery drops to a certain level, the vehicle switches to HV.
