Hi all,

I'm noticing in my '14 CR-Z that the auto-stop feature will activate upon coming to a stop, but will automatically switch the engine back on after around 10-15 seconds. At first I thought it was because I was shifting my foot on the brake pedal a little, but after experimenting with it a few more times it seems that the auto-stop on my car simply turns the engine back on after turning it off for a bit. This can't be normal right? Why wouldn't it keep the engine off until i release the brake pedal?

Any advice on the subject would greatly appreciated. Thanks everyone!

How charged is the hybred battery, autostop will come on if it drops to 2 bars, or if the underhood battery is weak and the HIDs are on. The system accounts for enough charge to kick over the engine and weak 12v batteries play havoc on the system. (autostop resume and drive can become jerky)

Autostop on CVTs will kickin when stopping from high gears but when the car is running at a stop start crawl it may not engage.

Another thing, when front windshield demister is pressed or on it turns autostop off - makes a handy autostop deactivator button.

Any other strange behavior? as others have mentioned it can be an under hood battery issue or other factors. My 2013 has done what you describe once or twice but nothing consistent. What is consistent is my re-circulation light for A/C turns on when in auto stop in warm weather with Air conditioning and heating off.


Your reported auto stop issue is much different. To rule out the under hood battery get a load test ( with engine not running). Many places will do this simple test for free. If battery is original OEM Honda with the Eye it is now over 4 years old and if it were me I would just replace it.

Always good to check the 12v battery, but What drive mode and climate settings are you using?

There's an override if the cabin temp gets too far away from the set temp on the climate control. ECON mode pretty much has no autostop overrides besides the defrost.

If it's a manual, and you are shifting from neutral to 1st it will restart when you put it in gear, or mine does. I usually leave it in neutral when coming up to the light, and stay in neutral till I see the light is getting ready to change to green.

UPDATE 8/30/2019
It seems as though whenever I don't run the AC, autostop always works without fail. However, when I have the AC on, it will do the aforementioned thing of only turning off the engine for the first 10-15 seconds. I live on the West Coast, where it's quite chilly but we've had an unusually hot summer this year. The owner's manual does state that when the AC is on and there is a significant difference between outside and cabin temperature, autostop will not engage.
