Wondering what cars have OnStar built in? You’re looking at dozens of models across four major brands — and the answer might surprise you. Whether you’re shopping for a new truck, a family SUV, or an electric vehicle, this guide breaks down every OnStar-equipped vehicle and what you actually get with it.
What Is OnStar and Why Does It Matter?
OnStar is GM’s built-in connected vehicle system. It handles everything from automatic crash response to remote start, Wi-Fi hotspots, and hands-free highway driving.
Think of it as your car’s digital backbone — always on, always connected.
Here’s the big news for 2025: GM made OnStar Basics standard across every new Chevrolet, Buick, GMC, and Cadillac for eight full years at no extra cost. That’s a massive shift from treating connectivity as a premium add-on.
What Cars Have OnStar in 2025 and 2026?
Every new vehicle across GM’s four consumer brands ships with OnStar baked in. That includes Chevrolet, GMC, Buick, and Cadillac. Commercial BrightDrop vans also carry the system.
Here’s the full breakdown by brand.
Chevrolet: Connectivity Across Every Segment
Chevrolet covers the widest range — from budget-friendly crossovers to electric pickups and performance sports cars.
SUVs and Crossovers
The Trax and Trailblazer give entry-level buyers standard remote access and wireless connectivity. Step up to the Equinox, and you get an 11.3-inch touchscreen powered entirely by the vehicle’s persistent network connection — think Google built-in navigation and voice commands without needing your phone.
The three-row Traverse uses continuous map downloads to support hands-free driving. The Tahoe and Suburban lean on remote climate control and advanced trailering camera feeds.
Trucks
The Colorado and Silverado 1500 use OnStar for smart trailering apps and remote tire pressure monitoring. Fleet operators running Silverado 2500HD and 3500HD units depend on the system to track fuel efficiency and schedule preventative maintenance across entire fleets.
Electric Vehicles
For the Equinox EV, Blazer EV, and Silverado EV, OnStar isn’t optional — it’s operational. The system monitors battery health, manages charging schedules, and routes drivers to charging stations based on real-time range data. These Ultium-platform vehicles rely on persistent cellular connectivity to function at their best.
Performance: Corvette Lineup

GMC: Professional-Grade Telematics
GMC focuses entirely on trucks and SUVs. The connectivity here leans hard into towing, off-roading, and premium tech.
SUVs
The Terrain handles the entry-level work. The Acadia steps it up with a 15-inch head-up display that pulls data from the vehicle’s live connection. The Yukon and Yukon XL use the network for heavy towing analytics and real-time safety data across long road trips.
Trucks
The Canyon AT4X uses OnStar to optimize terrain modes and transmit GPS location during backcountry trips where your phone has no signal. The Sierra 1500 processes data for 14 different camera views — including a transparent trailer view. The Sierra 2500HD and 3500HD feed fleet managers live engine and transmission health alerts.
Electric Trucks
The Hummer EV — both pickup and SUV — runs complex off-road energy mapping through the cellular connection. The Sierra EV manages a battery pack capable of up to 460 miles of range and supports hands-free highway driving.
Commercial
The Savana cargo and passenger vans use OnStar for location tracking, driver behavior monitoring, and fleet uptime management.

Cadillac: The Most Connected Vehicles in GM’s Lineup
Cadillac pushes OnStar integration furthest. New Cadillac buyers also get three years of a premium tier included at purchase on top of the standard eight-year Basics package.
Sedans
The CT4 and CT4-V Blackwing use OnStar for performance telemetry and dynamic navigation. The CT5 and CT5-V Blackwing feature a 33-inch LED display that depends entirely on a high-bandwidth connection to run properly. At the top sits the CELESTIQ — an ultra-luxury EV starting around $361,000 that uses the network for bespoke concierge services and real-time software tuning by specialized technicians.
SUVs
The XT4, XT5, and XT6 use OnStar to power safety suites and mobile app access. The Escalade and Escalade ESV manage sweeping OLED displays, rear-seat entertainment zones, and advanced stolen vehicle tracking — all through the telematics network.
Electric Vehicles
The OPTIQ handles range anxiety through connected route planning. The LYRIQ’s 33-inch curved display streams media and manages battery pre-conditioning. The VISTIQ bridges mid-size efficiency with full-size space using a full advanced safety suite. And the Escalade IQ and IQL bring a 55-inch pillar-to-pillar LED display — the whole thing runs on the underlying telematics infrastructure.
| Cadillac Model | Category | Starting MSRP | Key OnStar Use |

BrightDrop: OnStar Goes Commercial
BrightDrop 400 and 600 electric step vans are built for last-mile delivery. They’re the first commercial electric vans with OnStar’s full safety and security system built in from the factory.
Fleet managers use the system for real-time GPS tracking, automatic theft alerts, and remote ignition blocking. The vans also run over 20 active safety features — including intersection automatic emergency braking and pedestrian detection — all updated and logged through the persistent cellular connection.
What Do You Actually Get With OnStar for Free?
Every 2025 and newer GM vehicle includes OnStar Basics for eight years at no cost. Here’s what that covers:
- Automatic Crash Response — sensors detect airbag deployment and connect you with an emergency-certified advisor who sends your GPS location to first responders, even if you can’t speak
- Remote Commands — lock/unlock doors, remote start, location sharing, and vehicle health monitoring via mobile app
- Google Maps and Google Assistant — built-in, no phone needed
- Audio app streaming — music, podcasts, and news direct to your display
What Are the Paid OnStar Plans?
If you want more than the basics, OnStar offers five paid tiers:
| Plan | Monthly Cost | What It’s For |
|---|---|---|
| Connect | $14.99 | Audio streaming, voice assistant, navigation |
| Connect Plus | $24.99 | Wi-Fi hotspot for 7 devices, video streaming, browser |
| Protect | $29.99 | 24/7 advisors, stolen vehicle help, Guardian app |
| Super Cruise | $39.99 | Hands-free driving on compatible highways |
| One | $49.99 | Everything in Connect Plus and Protect combined |
The Guardian app — included with Protect — is worth calling out. It extends OnStar’s emergency features to your smartphone, so you’re covered even when you’re not in your own car.
Can You Get OnStar in a Non-GM Vehicle?
Short answer: sort of.
GM tried an aftermarket mirror called the OnStar FMV from 2011 to 2014. It worked in nearly any vehicle made after 2000. But professional installation costs, acoustic problems, and the rise of smartphone navigation killed demand — and GM discontinued it in March 2014.
Today, fleet operators can connect non-GM vehicles using the OnStar Vehicle Insights OBD-II adapter. It plugs into any vehicle’s diagnostic port and adds GPS tracking, driver behavior monitoring, and health alerts to a unified fleet dashboard.
Individual drivers in non-GM vehicles can download the OnStar Guardian app for standalone emergency coverage through their smartphone.
What Happened to Older OnStar Vehicles?
Older vehicles — generally those made before 2015 — ran on 2G and 3G cellular networks. When US carriers shut those networks down between 2022 and 2023, those built-in OnStar systems stopped working entirely. Models from discontinued GM brands like Pontiac, Saturn, Saab, and Oldsmobile were all affected.
GM offered some fixes: over-the-air software transitions for select 2015 models and an OBD-II plug-in adapter for basic connectivity. For most owners, the Guardian app became the practical replacement — it uses your phone’s sensors instead of the car’s built-in module.
The Mandatory Subscription Controversy (And How It Ended)
In 2022, GM required buyers of new Buick, GMC, and Cadillac vehicles to pay for a mandatory three-year premium subscription — baked into the vehicle price at $900 to $1,500. You couldn’t remove it even if you didn’t want it.
Consumers pushed back hard. Rising interest rates and inflation made the forced cost even more unpopular.
GM reversed course for 2024 models. Now, only top-tier luxury trims — like GMC Denali, Buick Avenir, and the Cadillac Escalade — bundle premium subscriptions into the purchase price. Everyone else gets the eight-year Basics package, with paid tiers as a genuine choice.
The Data Privacy Issue You Should Know About
OnStar collects detailed data: speed, location, braking, acceleration — logged continuously.
GM used to run a program called Smart Driver that let you share this data with insurance providers for potential premium discounts. Sounds useful. But investigations revealed that driving data was sold to third-party brokers like LexisNexis and Verisk, leading to insurance rate increases and policy cancellations — often without drivers knowing they were enrolled.
GM shut down Smart Driver entirely in April 2024 and cut ties with those data brokers. All eight million enrolled customers were removed from the program automatically.
It’s a reminder that connected features come with real data implications. Knowing what you’re opted into — and what you can opt out of — matters.
