Default MD Mondeo Titanium - voltage sensitivity issues?

Question, does the Mondeo suffer from electrical glitches when the voltage of the battery starts to waiver. Assuming original battery (2015), and last few months have noticed the following one off/now and again electrical Gremlins:
Rear door sensors won't unlock or lock the vehicle
Blinker giving odd ticks. Tick tock tick tock ........ticktock tick tock etc
Headlights gave an "Adaptive headlight error
Bluetooth connectivity issues

I recall my G6e Turbo was sensitive to the battery voltage, aircons, temp sensor, tune issues etc. Was wondering if the Mondeo is the same and the battery is due to change.

Most modern vehicles which are heavily reliant on electronic modules and which are equipped with OEM batteries that are (at best) marginal for the load will display unusual and inconsistent issues when faced with a struggling battery.

If you can fit one, go the next rating up for a replacement.

Is that actually a likely case with Mondeo though? At least for the previous model (MC), the OEM fit was a decidedly outsize battery to account for the Euro winters...
