Yes, your car is spying on you. And car manufacturers are using the information they spy against you.

TL;DR: Long story short: Guy buys a new Corolla. It catches fire. Toyota uses the information gleaned through the app to deny what seems to be a legitimate claim because their app found out the guy drove the car at speeds in excess of 85 mph — even though the car is built to be driven at higher speeds than that. Same thing happens to another guy. Warranty claims for the sudden engine fire are again denied based on information communicated to Toyota through its app.
