Neither do I, and that's concerning. Here's their privacy policy:

Connected Vehicle Data

If you have a connected vehicle, your vehicle may be equipped with NissanConnect Services, which electronically transmits data generated by your vehicle. This information could include data collected in the context of a trial period or demonstration mode. Through these services, we may obtain vehicle and driving information, such as:

• Vehicle operation – including Vehicle Identification Number (VIN), Precise Geolocation and navigation information, speed and distance information, driving behavior, EV battery information (including use management, charging history and performance), electrical system functions, diagnostic trouble codes, maintenance conditions, software version information, and similar data
• Vehicle usage – your use of the vehicle’s functions and some corresponding services, websites and smartphone applications
• Vehicle status – information about door locks, open doors, engine status, etc.
• Vehicle safety – data about certain accidents involving the vehicle (for example, the direction from which the vehicle was hit, and which air bags have deployed)

I don't know if NissanConnect is optional (looks like it is?), or if it's "optional," as in you need to accept to access core car features, like setting battery charge limits, redeeming a warranty, or accessing diagnostics. But I know the capability exists and I'd really like to have guarantees, as in, can I block Nissan from remotely accessing my vehicle? If not, can I remove the module without impacting other functions of the car?

But it's really hard (at least in my few minutes of searching) to figure out what privacy concerns there are and what options I have to deal with it.
