USA traffic engineers love stop lights which force idling. Fortunately some European tech to stop/start the engine is arriving in USA. In isolated cases, some USA intersections are being converted to traffic circles. Installation of new stop lights should require a giant pollution fine paid by government.

My 2018 Ford escape has auto-stop/start when stopped. But it almost never works. No idea why. It worked for the first year maybe, then disappeared.

It can be turned off, and there's very little visual indication that this has happened. The feature bugs some drivers, so if you have a second driver, they could have easily done it.

I've toggled it many times to no avail.

Sometimes dealer updates change settings. I saw a Subaru change behavior with lane departure warnings after an oil change.

I've had this this issue on my Mercedes before, the cause turned out to be the 12V battery that never charged properly, so the system didn't want to activate.
