But I'm not sure if that has everything or just the major safety recalls.

I'd love access to the same database that the car dealerships use when you bring your car in for service. For example, I had the transmission fail in my Honda Accord a few years ago, and the dealer pulled up my VIN and noticed it was part of a transmission-recall-thingy where they didn't notify owners, but extended the transmisison warranty to 5 years in case an owner had trouble. That's the thing I want access to. Didn't find it last time I looked.
