Voltage fluctuations and deep sleep mode 2022 Mustang gt

[Vlad Soare]

Where did you read this? My car has sat for two weeks without going into deep sleep. Even remote unlock still worked.

I have noticed it myself, and it's also in the service manual:

I haven't seen the exact number of days specified anywhere, but in my case it's always seven. Each time I was away from home for more than seven days (the battery being full and connected to a charger during this time) it was always on the seventh day that FordPass notified me that the car went to sleep. Always on the seventh day, no exception.
Now, it could be that the precise number of days varies from one car to the next, depending on optional extras, or battery size, or perhaps market, or something like that. I stated seven day above because that had been my experience, but you're right, the exact time limit might vary.

Your "Ford App" is a glorified spy and really is of no other real use. I suggest you uninstall it and never use it again. They just emailed me telling me they miss me, like an old GF that got dumped again.

Oh the car spies too lol, unless you pull the telematics fuse.

I didn't notice it until I had work done on my car either but it is very common. for voltage to vary between 12.5 and 15 on these cars.

It stopped doing it and is charging properly now. My guess is the dealership service mechanic left something on and discharged my battery. I drove it around for a couple days and it's working properly now.

[...] but I did notice the service people messed with my settings on the car and even had their phone paired to my stereo..

Sounds like someone had fun.
