I like everyone else it seems is not a fan of this feature BUT I think I may have discovered something yesterday.

As least on my car, a Q, this feature seems to be sensitive to the amount of pressure you apply to the brake. I did several experiments and they all came out the same.

When coming to a stop I gently and immediately release a little pressure on the brake pedal after stopping but still staying stopped. The engine won't switch off! If I apply a little more pressure, it will switch off.

Wondering if anyone else has come had the same discovery?

Yes, I have as well on my Ti. Outside temp also plays a factor. If you have the auto temp setting on and the car doesn't feel it is cool enough inside based on your temp setting, it will not turn off either.

I still try and remember to turn it off.

Same here. I use it a little differently though: when I anticipate the traffic light to turn green, I release a little of the brake pressure to start the engine, such that take off would be much smoother. But I like your technique, will be useful in situations where you only need to stop briefly (e.g. stop signs) and really don't want stop/start to kick in.

Within a nanosecond of my engine start the Stop/Start system is turned off at the switch.

I have zero use for this feature!

Actually, if you read through the Users Guide/Owners manual, there are several circumstances that Stop/Start will not activate. Cold weather is definitely one of them. Battery not sufficiently charged, Driver's door not shut, Engine still cold........

Start / stop - dangerous situation

I am driving Alfa Romeo Giulia Launch Edition, and I want to share with you a normal driving occasion, with a perfectly normal sequence of events:
Imagine that you are coming to a complete stop by the sidewalk at the end of a trip, and the Start-Stop shuts the engine off automatically. You normally press the Stop button to cut off the engine, but the engine is already off and nothing happens. You release the brake on your way out of the car, but all of a sudden the engine comes to life automatically, and the car jumps forwards.

I find this situation very dangerous and seek an advice.

1. What should I do to avoid this dangerous situation ?
2. Can the Start / Stop be deactivated as a default ?

Hi there,

I had provided a response to your question in your earlier post. As I indicated, based on the steps you took, you skipped placing the car in park because you assumed the car was off when it technically was not (only the engine was off). You have to keep in mind that the car is not technically off when the auto stop/start feature comes on when you come to a stop; only the engine is stopped. That is why when you lift your foot of the brake, the engine turns back on. However, when you actually put the car on park and press the stop/start button, that is when you actually turn off your car. As I stated earlier, this is a driver's error not a technical glitch or an oversight in the system design by AF.

This wouldn't happen if you put the car in park before pressing the start/stop button to turn off the engine. The car would not launch forward. This was a drivers error.

Under normal operation, when you turn the engine off, the car will automatically go into Park and put on the handbrake. I don't encourage this and I think it is bad practise and a bad habit to get into. However, some dealers are actively demonstrating this feature. I can understand how users would consider simply turning the engine off without needing to select Park first a design feature, and get into the habit of doing this.

If the engine does not switch off when start/stop is active and no warning is given that the engine hasn't been switched off as commanded, this is a safety issue.

For obvious reasons, I would not recommend bypassing the park sequence when you are getting ready to turn off and exit your car. Like you said, its a very bad habit which can be dangerous. Did you ever do this to any other car with the PRND transmission? Turn off the ignition without first placing the car in "P"? So why would you do it on this car? What to save a 1 second? Its just a press of a button to press "P" so you are 100% sure your car is not going any where.

If the engine is off because the auto stop/start function activated, just press the auto stop/start button (next to the headlight turn knob) and disable it. Your engine will immediately turn on without having to lift your foot of the brake (if you are paralleled park and cannot afford moving a few inches without bumping the car in front of you). Then go through the correct shut off sequence when fully stopped.
1) Press "P"
2) Press the engine on/stop button (which may enable the automatic handbrake feature depending on your personal settings).
3) Relax as you exit your vehicle knowing that your car is not going anywhere.

Thank you ibehardnock2001 and casino.

I will try putting the car in Park before pressing Start / Stop.
Nevertheless, I am still looking for a possibility to deactivate the automatic Start / Stop as a default.

No problem. Glad to help. Currently there is no way to permanently disable the automatic start/stop feature (yes it is very annoying). You can disable it once you turn on your car and it will remained disabled until you turn off you car. But the moment you turn it back on, its enabled again.

I have the same issue. Try to go really light on the brake so as not to activate stop/start before you turn off the car ( push the start button). Whenever I get this wrong it ends up that the car motor turns on an unnecessary additional time. I think this is terrible. We can learn around it but I would bet this ends up in a safety recall ( remember the killer Jeep Cherokee shift lever problems from a couple years back?). I can just see my father-in-law borrowing my car and then plowing it into something as he starts to get out...
