My Lucid Air shows "12V system fault." What should I do?

Short answer: Call Lucid support. Owners say service will pick up the car and give a loaner. Owners point first at a loose 12-volt connection or a worn 12-volt battery, and say it's rare on Lucids. Don't keep driving on it, because the 12-volt system powers the computers that run the car. Also run your VIN for the Air recalls about loss of drive power.

Symptom: A '12V System Fault' message on the display, sometimes on a brand-new car.

What to check first

1. Photograph the message and note when it appeared.
2. Call Lucid support and ask for pickup and a loaner.
3. Ask service to check the 12-volt connections and test the battery and its charging.
4. Run your VIN at nhtsa.gov/recalls.

Likely causes

1. Loose 12-volt battery connection. A connection that isn't tight can drop power to the car's computers.
2. Worn or failing 12-volt battery. Almost every modern car, including EVs, has a small 12-volt battery that powers the computers, locks and screens. When it's weak or isn't being recharged, the car can show a pile of unrelated warnings or refuse to go into gear, even with a full main battery.
3. Other low-voltage system faults. The system that keeps the 12-volt charged can fail too. Lucid service has to read the codes to know.

What it usually costs

Owners' repairs were handled by Lucid service and they didn't post prices.

Is it safe to keep driving?

Treat it as don't-drive until Lucid looks at it. A failing 12-volt system can shut down the car's computers while moving.

DIY or shop?

Leave it to Lucid service. An EV's high-voltage system can stay live with the car off. Leave the orange cables, the big battery and the drive unit to a trained EV technician.

What owners report

• In 12v System Fault 2024 Air Pure on Reddit r/LUCID, an owner whose 2024 Air Pure was about a day old got a '12V System Fault' message. Lucid customer care arranged a truck to pick up the car, and owners said Lucid provides loaner cars.
• In 12V system fault on Reddit r/LUCID, someone posted a photo of a colleague's Lucid with a 12V system fault. Owners said it could be a loose 12-volt connection or a 12-volt battery that needs replacing. A three-year owner said it was the first 12-volt issue they'd seen on a Lucid, even though it's common on other EVs, and said to call support.

Quick tip

On a new Lucid this is warranty work. Let them come get it, and ask what failed so you know if it's likely to come back.
