Add FSD to a Hyundai Santa Cruz? Here's what works
Tesla's FSD stays on Teslas. But your Santa Cruz can steer itself and follow traffic with one device plugged in behind the mirror.

Yes. Your Santa Cruz is on comma's list.
comma lists the 2022–2024 Santa Cruz. It needs Smart Cruise Control (SCC) on the car. The car's own adaptive cruise keeps speed control; an early openpilot option exists. Steering works all the way down to a stop.
Towing and long drives in your Santa Cruz
Yes, comma works while towing with the right setup. It’s an amazing upgrade for long highway drives.
Stay especially vigilant and ready to steer or brake. You remain responsible for your truck and trailer.
Match your truck’s year, equipment and software before buying. Confirm your trailer setup with the software project and follow your vehicle’s towing instructions.
Make long drives and towing easier in your Hyundai Santa Cruz
Steers itself in the lane
Continuous centring on highways and most roads, not a nudge back from the line.
Follows the car ahead
Your car's adaptive cruise keeps doing the gas and brakes while openpilot steers.
You stay in charge
A driver camera checks your eyes. No city turns, no naps, no FSD claims.
Every Santa Cruz comma lists
Open your year for the exact trim, harness, and what controls speed.
How to add it to your Santa Cruz
Four steps. No wiring cut, no dealer visit.
- 1
Confirm your year and trim
Open your exact Santa Cruz below. Trim names decide whether the car has the cruise and camera openpilot needs.
- 2
Order the comma four with the Hyundai N connector
Pick your car in comma's shop and the right harness is added. Nothing else is required.
- 3
Mount it behind the mirror
Stick the mount high and centred, plug the harness in at the camera, and route one cable. About fifteen minutes.
- 4
Drive a few minutes, then engage
It calibrates on your first drive. Then press your cruise button and the Santa Cruz takes the lane.
What the first drive is like
Highway Driving Assist versus openpilot
HDA centres the lane on highways with clear markings and only on some trims. openpilot adds centring on most roads to listed Hyundais, HDA or not.

Questions Santa Cruz owners ask
Do I keep Highway Driving Assist?
Yes. The harness sits between the car and its camera, and your factory safety features keep working. Unplug it and the car is stock again.
Does it handle stop-and-go traffic?
Yes on the listed Santa Cruz years. It slows to a stop behind traffic and moves off again on its own.
Is there a subscription?
No. The device and the software are a one-time purchase. comma prime is an optional extra for remote access and longer drive storage.
Do I need to keep my hands on the wheel?
Not constantly. A small camera watches that your eyes stay on the road, and openpilot warns you and stops steering if they do not.
