Our 2021 Badlands has done this since new, always when backing out of the garage. Compared to the battery issues, this little "moan" is the least of our problems.
The wiring diagrams I have show the Cup holder, and foot well lights connect to the BCM C2280D on pin 31, which they call LIN11
All three LIN lines are tied together on splice S207, that's in the main harness somewhere.
One of the things that "clicks & clacks" with other whirring noises is the EVAP system. Seems this will run every 3 days or so to check the fuel tank. I've heard it run even after the car is parked for a week in the garage.
I have a 2021 Badlands and previously a Forester. The ground clearance between the two is about the same at 8.5 inches. Great for snow and off road but not what you would want for high speed cornering, even with stock tires. Before buying the Badlands I test drove a CX5 Turbo. I felt the Mazda...
This was very likely a low battery voltage issue. We had this happen on our 2021 recently. It had no other issues other than low battery voltage during crank.
You are in Ohio, I'm in PA. In PA if a trailer is equipped with brakes in PA then they MUST be used to be legal, regardless of the weight of the cargo. For 5 miles I'm not sure it would be worth worrying about in your state.
The 4 pin has GND - Stop/Right - Stop/Left - PARK
My guess is they will tap into the parking lights for a trickle charge.
The Ford 7 pin has all the above plus: Left Park - Right Park - STOP.
I test drove a CX30 before knowing about the BS. I had the Mazda Dealer looking for one that I wanted. But then Ford announced the Bronco Sport. The Mazda Dealer still hadn't come through with a CX30 so we ordered the Sport. The CX30 inside felt smaller to me.
You can do your own simple load test if you have a VOM that records MIN Voltage. Attach your VOM directly to the battery (with engine off). Reset the MIN memory on the VOM. Then start up the engine. The VOM should record the MIN starting voltage. On a healthy battery with a full charge it really...
