Different manufacturers have different terms for this technology. In summary what it does is kill the engine when you stop while still in gear, e.g. at a stoplight. Then when you release the brake the engine will restart. Let's just say that this is not a very popular feature in newer vehicles.
I had wrestled with this new-fangled technology when I was shopping for an SUV in late 2017. I actually bought a lower model SUV to avoid this technology.
3 years later my daughter bought a 2019 Chevrolet Traverse. Needless to say it had this Stop/Start feature. While it irritated her she tolerated it.
She had an aftermarket DVD system installed. When the engine restarted as she released the brake the DVD system sensed the voltage drop and powered down. This didn't sit well with her 3-year old.
The organization that had installed the DVD system performed all the tricks that they had with no resolution.
I acquired SmartStopStart from smartstopstart.com. The method of installation was to install the device inline with the sensor for the hood. It worked by tricking the ECU into thinking that the hood was open when the engine started. This succeeded in defeating the Stop/Start and the engine keep running. However, the remote start capability no longer worked. The vendor worked closely with me but couldn't overcome the loss of remote start. I returned the device.
Then I came across the Start/Stop Disabler from Range Technologies. The method of installation was even easier that SmartStopStart. It simply plugs into the OBD2 port under the dash.
And it works perfectly.
