This has been brought up before but I managed to film it if anyone out there wants to hear the new and old Lincoln chime sounding on the MKC. The old quad-tone chime happens when the battery is low. I also see a message on the infotainment screen saying the car is entering power-saving mode. I learned today I need a new battery because it's not holding a charge for very long based on my battery tester. When I ran the engine for a few minutes and turned the lights on again the new tri-tone chime sounded. This has also happened to my 2018 F-150 but those new and old chimes are different than what Lincoln uses (and I have a video of it).
