2016 - close on you and stop when there’s resistance, but it has to bump on you or your kid first. Is this a safety issue? Well it’s just same as regular door where you close the door when someone is still standing there.
Late 2017+ (q3? Q4?) - if someone is standing below the opened FWD, it won’t close or move at all. Here you have about 3 seconds to move away so the door will start closing. If you don’t move away the door will stay put and not close, with a warning beep beep beep. If for whatever reason the sensor does not sense any object but you are there, it acts like 2016, close and stop after getting resistance. I had this happened on my 2018 because the SC forgot to plug back in a wire bundle after fixing the FWD. It defeated the sensor and the LED down light. I opened up the panel and plugged it back in myself.
Most likely not something the SC will retrofit as it’s not a plug&play item like FWD switch. The sensor is inside the speaker grille in case you are wondering.
