When I saw the RPM to zero it reminded me of Ford C Mxax Hybris we used to owned. Where you feel the engine stop working and then start up once you accelerated. When the van did this I could not tell if the engine stopped running or not. ---

> [@tucoramirez](#): > > When the van did this I could not tell if the engine stopped running or not. From afar, I don’t think that anyone can give you a good diagnosis unless you can figure out whether the engine is running–or if it isn’t running–when the tach shows zero. But, in order to rule out the possibility that this situation is just the “normal” engine stop/start cycle, you should temporarily disable the auto stop/start by pressing this button. ![image](https://global.discourse-cdn.com/cartalk/original/3X/0/7/072e69614aed8610c169bfd9041d92ba1d21f656.png) The placement of these buttons varies from model to model, but the symbol is the same. Remember that you need to do this after each time that you start the engine, as you can’t disable it permanently. ---

OP can’t tell if motor is stopped. Zero tach could be clue though. Have someone look at motor while stopped. Belts turn? ---

> [@tucoramirez](#): > > we purchased the car used in Dec 2023 and have not ever seeing the RPM go to zero until yesterday. The car is smart enough to know that it shouldn’t auto-stop the engine if the battery system may not be robust enough to start it again. You probably had a weak battery when you bought the car. ---

I think Asemaster got it right. Now that you replaced **one** of the batteries I still am of the opinion you should replace **both** ) the start/stop is now functional. ---

Don’t open the hood when doing this test. I’d say once the car knows the hood is open, the stop\start function may deactivate. Also there should be an indicator somewhere in the dash stating when your engine is not running due to stop\start feature. ---

As a test, leave hood popped. Motor will never shutoff. ---

I’ve never been told something like that while seeking help in person but I’ve been told that many times on the internet. Courtesy and friendliest go a long way. 😉 ---

You know what else also goes a long way? Accepting the advice that knowledgeable people give you and TAKING that advice . . . versus repeatedly asking the same questions and making the same comments, desperately hoping that someone will tell you what you want and/or need to hear 🤔 That wasn’t directed at one single person, btw ---
