Yes, you can add Super Cruise after purchase, but the cost and process depend on your model year and trim level
Cadillac allows owners to retrofit Super Cruise to vehicles that were not equipped with it at the factory, but not every car qualifies. The system requires specific hardware — primarily the LiDAR sensor mounted on the roof — that must be physically installed. Cadillac handles the retrofit through authorized dealers, and the total cost typically runs between $2,000 and $2,500 for parts and labor, though this varies by location and dealer.
The main limitation is model year. Super Cruise retrofits are available for 2021 and newer Cadillac CT5 and Escalade models. Older vehicles and other Cadillac lines do not support the retrofit, even if they have the required infotainment system. Before you contact a dealer, confirm your model year and trim — not all trims within a model year are compatible.
Key Takeaways
- Super Cruise can be added to 2021 and newer CT5 and Escalade models through a Cadillac dealer, but older model years and other Cadillac vehicles do not support retrofit.
- The retrofit includes the LiDAR sensor, wiring, software updates, and labor, with total cost typically between $2,000 and $2,500 depending on your location and dealer.
- Your vehicle must have the compatible infotainment system and meet other hardware requirements — your dealer can confirm compatibility during a consultation.
- The installation takes several hours and requires your vehicle to stay at the dealer, so plan for a service appointment rather than a quick add-on.
What hardware your car needs to support Super Cruise
Super Cruise is not purely a software feature. The system relies on LiDAR (light detection and ranging) to map the road and detect obstacles, plus a forward-facing camera, radar, and ultrasonic sensors. If your vehicle was not built with the LiDAR sensor on the roof, the retrofit must install it along with the necessary wiring harnesses and control modules.
Your car also needs the compatible Cadillac infotainment system — typically the newer generation with the larger touchscreen — to run Super Cruise software. Vehicles with older infotainment platforms cannot be upgraded to support it, even if they have the sensors installed. A dealer can check your specific vehicle's configuration and tell you whether a retrofit is possible.
Which Cadillac models can receive Super Cruise
Currently, Cadillac offers Super Cruise retrofits for the CT5 sedan and Escalade SUV, but only for 2021 model year and newer. The CT5 became available with Super Cruise as a factory option starting in 2021, and the Escalade added it in 2021 as well. If you own a 2020 or earlier CT5, or any other Cadillac model, a retrofit is not available.
Cadillac has not announced retrofit availability for other models such as the XT4, XT5, XT6, or CTS. The company may expand the retrofit program in the future, but there is no timeline for that. Check with your local Cadillac dealer about your specific vehicle — they have the current list of compatible models and can confirm whether yours qualifies.
The retrofit installation process and timeline
The installation is not a quick service. Technicians must remove interior and exterior trim panels to run wiring from the roof-mounted LiDAR sensor to the vehicle's control modules, typically located under the dashboard or in the engine bay. They also install or update software and calibrate the sensors to may support they work correctly. The entire process usually takes 4 to 8 hours, depending on the vehicle and dealer workload.
You will need to leave your vehicle at the dealer for at least one full business day, and possibly longer if the dealer is busy or if complications arise during installation. Schedule the appointment in advance and ask the dealer for an estimated completion time. Some dealers may offer a loaner vehicle while yours is being serviced, but this is not may provide — confirm availability when you book.
Cost breakdown for a Super Cruise retrofit
The total retrofit cost falls into two categories: parts and labor. The LiDAR sensor and associated hardware typically cost $1,000 to $1,200, while labor and software updates add another $1,000 to $1,300. Your total out-of-pocket cost is usually between $2,000 and $2,500, though regional differences in labor rates and dealer pricing can shift this range.
Some dealers may offer different pricing, so it is worth calling a few authorized Cadillac dealers in your area to compare quotes. Ask each dealer for an itemized estimate that breaks down parts, labor, and any additional fees. Also ask whether your vehicle's warranty covers any portion of the retrofit — in some cases, remaining factory warranty may explore to the newly installed components.
How to order and schedule a Super Cruise retrofit
Start by contacting an authorized Cadillac dealer and telling them your vehicle's model year, trim level, and current mileage. Ask whether your specific vehicle is compatible with the Super Cruise retrofit. The dealer can look up your vehicle identification number (VIN) in Cadillac's system to confirm compatibility and provide an accurate quote.
Once you confirm compatibility and agree on pricing, schedule a service appointment. Provide the dealer with your preferred dates and ask how long the installation will take. Confirm whether a loaner vehicle is available and whether you need to drop off your car or wait during the service. Some dealers allow you to schedule online through their website, while others require a phone call — check your local dealer's process.
Warranty and support after retrofit installation
Cadillac typically covers the newly installed Super Cruise components under a limited warranty for a set period after installation — usually one year or a certain mileage limit, whichever comes first. This covers defects in the hardware and software, but not damage from accidents or misuse. Keep your service paperwork, as you will need it to make a warranty claim if something fails.
After installation, you will need to set up Super Cruise in your vehicle's infotainment system and enroll in the service through your Cadillac account. Super Cruise requires an active subscription to function — the subscription cost is separate from the retrofit cost and is billed monthly or annually. Check Cadillac's current subscription pricing when you schedule your retrofit, as rates may change.
Frequently Asked Questions
Can I add Super Cruise to a 2020 or older Cadillac?
No. Cadillac only offers Super Cruise retrofits for 2021 and newer CT5 and Escalade models. Older model years lack the necessary hardware architecture and infotainment platform to support the system. If you own an older Cadillac, a retrofit is not available.
Will adding Super Cruise void my vehicle's warranty?
A retrofit performed by an authorized Cadillac dealer should not void your existing warranty. The newly installed Super Cruise components are covered under their own limited warranty. However, if the retrofit installation causes damage to other parts of your vehicle, those repairs may not be covered. Ask your dealer about warranty implications before scheduling.
Do I need a subscription after the retrofit is installed?
Yes. Super Cruise requires an active subscription to operate, separate from the one-time retrofit cost. You will set up the subscription through your Cadillac account after installation. Subscription pricing varies — check with your dealer or Cadillac's website for current rates.
How long does the retrofit installation take?
Installation typically takes 4 to 8 hours, depending on the vehicle model and dealer workload. You will need to leave your car at the dealer for at least one full business day. Some dealers may complete it faster if they have availability, so ask for an estimated timeline when you schedule.
Can I install Super Cruise myself, or does it have to be done at a dealer?
Super Cruise retrofit installation must be performed by an authorized Cadillac dealer. The system requires precise sensor calibration and software integration that only dealer technicians are equipped to handle. Attempting a DIY installation would not work and could damage your vehicle.
