If you’re old enough to remember when the biggest privacy concern in a car was whether somebody found your road atlas in the glovebox, I’ve got news for you.
Today’s vehicles know a lot more about you than your old Buick ever dreamed of.
They know where you live. They may know where you work. They often know where you’ve been, who you called, what music you listen to, what addresses you’ve searched, and sometimes even how aggressively you drive. Depending on your vehicle and which connected services you’ve activated, they may also know your favorite destinations, garage door settings, and information synced from your phone.
Before anybody panics and starts disconnecting battery cables, let me say this up front: this isn’t a conspiracy, and your car probably isn’t secretly recording your dinner conversations.
Most of this data collection exists for reasons consumers actually want.
Navigation needs location data. Voice recognition needs commands. Remote start apps need connectivity. Crash notification systems need vehicle data. Service reminders need mileage and diagnostics. If you want your car to start from your phone while you’re drinking coffee inside, information has to move somewhere.
The problem isn’t necessarily that vehicles collect data.
The problem is most people have no idea how much.
My friend Kim Komando recently highlighted something that really caught my attention, if you missed her special report in my newsletter last week: modern vehicles have become rolling computers, and many owners never think about what stays behind after they connect their phones, enter destinations, pair apps, or trade the vehicle in.
She also pointed our readers to a free tool called Vehicle Privacy Report that allows consumers to enter a VIN and see the types of data their vehicle may collect, store, and share under manufacturer privacy policies. It’s eye-opening and worth a few minutes of your time.

And here’s the part that surprised me.
According to information Kim discussed, many used vehicles still contain information left behind by prior owners—things like contacts, navigation history, saved destinations, Bluetooth information, and personal settings. I get in cars to review and see all the last reviewers info on a regular basis.
Think about that for a second.
You’d never sell your phone without wiping it.
You’d never hand somebody your laptop and say, “Good luck sorting through my texts and passwords.”
But people trade vehicles every day and never touch the infotainment settings.
And here’s where it goes from inconvenient to potentially concerning.
Most people have their home address saved as “Home” in navigation. Many also program HomeLink or another built-in garage door opener into the vehicle. Add in synced contacts, call history, connected apps, and destination history, and suddenly you’ve created a pretty detailed roadmap of your daily life.
Now imagine somebody gets access to that vehicle.
They don’t have to guess where you live.
Your car may literally tell them.
And if the garage door opener is still programmed and your address is stored? You can connect those dots yourself.
Now let me add another situation almost nobody thinks about: what happens if your car gets totaled.
After an accident, most people are focused on insurance claims, rental cars, injuries, and figuring out what to buy next. Very few people are thinking about the data sitting inside the vehicle.
But if your insurance company declares your vehicle a total loss, there’s a good chance it moves through a chain of places you never see—tow yards, storage facilities, salvage auctions, recyclers, rebuilders, transport companies, and eventually another owner.
Meanwhile, your infotainment system may still contain your contacts, recent destinations, Bluetooth pairings, text access, garage door codes, account logins, and saved locations.
Including “Home.”
If the vehicle still powers up, ask whether you can retrieve personal items and remove personal data before releasing it. Delete profiles, unpair phones, remove garage door settings, sign out of apps, and perform a factory reset if possible.
If the vehicle no longer powers up, remember to disconnect the vehicle from manufacturer apps and connected services accounts on your phone or through the manufacturer’s website.
We’ve learned to lock our phones and wipe our laptops.
Most of us haven’t learned to think of our vehicles the same way.
Now, before anyone decides to start using paper maps again, let me be clear: this doesn’t mean you should stop using these features. I use them too. They’re convenient and useful.
But convenience doesn’t eliminate responsibility.
Not every automaker handles data the same way.
Some information stays inside the vehicle and isn’t transmitted anywhere. Some data exists only to provide connected services. Some manufacturers provide privacy controls, opt-outs, or settings that allow drivers to limit what information is shared. Policies vary widely depending on manufacturer and even vehicle model.
That’s why I recommend every owner spend ten minutes exploring their vehicle’s settings.
Seriously.
Go into your infotainment system and look around.
Most systems today have menus labeled Privacy, Connected Services, Accounts, Profiles, Data Sharing, Vehicle Settings, or Factory Reset.
You may be surprised what’s enabled.
And if you’re selling, trading, returning a lease, or even leaving a vehicle for a prolonged service visit, do yourself a favor and clean house first.
Most modern vehicles make this relatively easy.
Almost nobody remembers to do it.
I’d also recommend opening the manufacturer’s smartphone app.
Many connected services continue working even after the vehicle changes hands, and account access may need to be removed separately from the vehicle reset process.
One more thing: pay attention when setting up a new vehicle.
We’ve all developed the habit of clicking “Accept” faster than we close cookie pop-ups.
Slow down.
Read what you’re turning on.
You may decide the convenience is absolutely worth it.
That’s fine.
But at least make it your decision.
Here’s the bottom line.
Your car isn’t spying on you in the Hollywood sense of the word.
But modern vehicles are collecting more information than most drivers realize—and once you understand that, you can enjoy all the convenience without accidentally leaving your digital life, your home address, and maybe even your garage opener sitting in the driveway—or the salvage yard—for the next owner.
