7 min readVivint Car Guard is a GPS vehicle tracker, connection to your smart home system, and diagnostic wizard all in one device. It’s smaller than a pack of cards and installs into your OBD II port like a USB stick. Once it’s up and running, you can check the location, driving history, and general health of your vehicle.
If you have teen drivers in your household, the Car Guard shows you their location and any dangerous driving habits like hard braking and speeding.
Low monthly payments
Works with Vivint lights, cameras, and garage door opener
Detects dangerous driving 
Expensive
Smart home features require a Vivint security system
Bump detection didn’t work in our tests 
While you don’t need a full-fledged Vivint security system to use this vehicle tracker, you do need a Vivint account. Your account email and password gains you access to the Vivint app where you’ll set up, track, and control the Car Guard.

♱ Vyncs charges annually, not monthly. Service for Vyncs Basic+4G starts at $99.99 per year.
When it comes to features, Vivint Car Guard matches top GPS trackers like Vyncs, MOTOsafety, and Bouncie. All four devices provide basic location tracking, vehicle maintenance alerts, and driving data like average speed.
We’ve tested other GPS vehicle trackers too. Check out our full reviews on MOTOsafety and Bouncie to see how they compare to Vivint Car Guard
But Vivint Car Guard has these unique features:
With these powers combined, you can scare off would-be thieves in your driveway to prevent car theft. If your vehicle detects tampering, it can trigger your outdoor camera and lights. It’s also super convenient to ditch the clicker and link Car Guard with your garage door opener.
We installed a Vivint Car Guard into our own vehicle to test this feature out. After rocking the car, jiggling the locks, and doing everything we could (short of actual damage), we couldn’t trigger the disturbance alert.
This doesn’t mean the feature’s a total dud, though. It may just mean your car has to sustain more serious damage to send an alert to your phone.
The Vivint Car Guard costs about $200 up front and $9.99 per month. That monthly cost goes towards supporting the cellular signal from the device itself to your app.
You can get additional Car Guards for teen and other adult drivers in your family for an additional $4.99 per month.
Compared to other GPS vehicle trackers, Vivint is more expensive up front. But after that initial expense, it falls within a similar range of other trackers. MOTOsafety, for example, is the cheapest vehicle tracker up front but costs over $20 per month. And, even though Vyncs omits monthly fees, a will will show up annually.
Its combination of tracking features, maintenance reminders, and alerts makes it a good addition to any vehicle—whether it’s yours or a loved one’s.
It’s a big day for families when a kid gets their driver's license. Before your kids hit the road, be sure to talk to your teens about safe driving. But even responsible kiddos can run into trouble.
Vivint Car Guard helps keep parents in the loop about their teens’ driving habits and whereabouts to make everyone feel more comfortable.
The Car Guard provides a driving score and alerts for dangerous driving habits like speeding and sudden braking. And parents can set boundaries that send alerts when teen drivers enter and exit areas like school, work, friends’ houses, and their own neighborhood.
Independence is important to adults of all ages, but as we get older, driving can become more of a hazard. Along with a medical alert system, devices like the Vivint Car Guard can help your aging parents drive longer.
If your parents forget to maintain their vehicle, Car Guard can send reminders about things like oil changes and basic maintenance. It also shows how much gas is in the vehicle.
The Car Guard offers a few benefits for your own vehicle beyond tracking. The movement sensor can alert you to fender benders, towing, and even vehicle theft. And along with vehicle diagnostics (I know I forget to change my oil), you can get fuel efficiency reports based on your driving habits.
If your vehicle was made after 1996, it should have an OBD II port. This is the space where your mechanic or other professional checks diagnostic codes in your vehicle. You can check for further vehicle compatibility on Vivint’s website.
The primary function of the Vivint Car Guard (and any GPS vehicle device for that matter) is tracking location.
But the Car Guard doesn’t stop there. You don’t just get the wheres; you get the whens and hows of each trip.
From the Vivint app, you can see your vehicle on a map, where it’s traveled, if it’s in motion, or where it’s going.
Every time your vehicle moves from point A to point B, Vivint provides trip details with information like distance traveled, trip duration, max speed, average speed, and fuel efficiency.
During our tests, we watched our vehicle live on the app. (Don’t worry; we weren’t driving.) The map had a hard time keeping up with the car’s location in real time but was able to place it accurately once the vehicle stopped.
If you have teens who borrow your car, you can set locations in the app where your kids are most likely to go. By entering the address of your kids’ school, workplace, or friends’ houses, you’ll get alerts when they leave or arrive at these popular spots.
Unfortunately, Vivint Car Guard doesn’t have geofences like the other vehicle GPS trackers we’ve reviewed. Instead, Vivint restricts locations to single addresses but geofences allow you to draw lines around larger areas like neighborhoods, cities, and even states.
One thing that sets Vivint Car Guard apart from other GPS vehicle trackers is the disturbance alert feature. If a bad actor tries to break in or someone hits you in the parking lot, you’ll get an alert on your phone.
Before testing, we thought this feature worked for small things like shaking the car or jiggling the handle.
We tried that and didn’t get an alert, which leads us to believe someone has to do actual damage to your car for these alerts to register.
The one disturbance alert we got was unintentional. After loading and unloading the trunk, we got one alert but no context. (Maybe Car Guard’s not a fan of heavy groceries either.)
As an anti-theft device, the Car Guard won’t stop thieves like a steering wheel lock might but it can warn you when someone breaks a window, giving you time to get to your car and investigate before they get too far.
If someone does manage to get away with your car, you can track it through the app.
And, as anyone who uses street parking knows, fender benders and towing are constant threats. If another driver bumps into your car or your vehicle gets towed, the Car Guard will sense the movement and alert you.
Vivint Car Guard takes the mystery out of those rumbles and scary dashboard lights by providing vehicle diagnostics before there’s a problem. The device watches for issues like battery life, DTC notices, recalls, and service bulletins. It can even tell you how much fuel is in your tank.
With over 10,000 diagnostic codes, this feature works for all types of vehicles with diesel, gas, or electric engines.
While Vivint Car Guard is far more expensive than other GPS vehicle trackers, it’s the only one we’ve come across that works with smart home equipment. The catch is it has to be Vivint equipment at your home. You won’t be able to sync up the device with any third-party equipment.
You can link the Car Guard and your Vivint Smart Home together. The Vivint Outdoor Camera Pro, Vivint Doorbell Camera Pro, and Vivint Indoor Camera can all be linked to the Car Guard through in-app automations. Plus, the garage door opener, smart lights, and other smart home devices can all trigger when you pull up to your driveway or if something disturbs your car while it’s in place.
Whether it’s with your own vehicle or a loved one’s, a feature-rich GPS tracker like Vivint Car Guard can save you a lot of potential headaches and worry.
Vivint injects its particular brand of smart home integration in the Car Guard to blend with your smart home components and keep you in tune with what’s going on with your car.
And, while the Car Guard is pricier up front than others like Vynce, MOTOsafety, and Bouncie, its features are worthwhile when paired with a Vivint Smart Home system.
We reached out to Vivint and received a Car Guard in person to test ourselves. To make the most of our experience, we downloaded the Vivint app and tested all the Car Guard’s features available to us. But we didn’t stop there.
Car Guard is just one of several GPS vehicle trackers we’ve tested in the past. Check out our reviews on Bouncie and MOTOsafety to learn more about how we tested these devices.
Our SafeWise methodology page is also chock full of information on what we look for in every review and how we approach new products like the Car Guard.
First, always lock your car, remove your keys from the ignition (even when parked for a short amount of time), and park in bright, populated areas when in public. You can also use tools like steering wheel locks, aftermarket car alarms, and kill switches to prevent any thieves from leaving with your car.
The Vivint Car Guard installs into your vehicle’s OBD II port and contains a SIM card. The port in your car allows the Car Guard to read diagnostic info about your vehicle while the SIM card uses a T-Mobile LTE signal to transmit cellular data to your phone. Combined, you get location and vehicle information sent directly to the Vivint app.
The FBI estimates over 700,000 motor vehicle thefts in 2019, causing $6 billion lost that year.1 Unfortunately, many of those vehicles are never recovered. A GPS tracker in your car, SUV, or truck can help you and local law enforcement find your vehicle and lead to capturing the perp who took it.
