On the GMC Hummer EV, this padlock-and-steering-wheel symbol means the steering lock mechanism has not released or has a fault. The engine may refuse to start until it clears.
How Urgent Is the Steering Lock Warning Light?

Is It Safe to Drive With the Steering Lock Warning Light On?
Safe-to-drive depends on judgement, and here is the technician's version for a GMC Hummer EV: respect the colour, respect the behaviour.

If everything feels normal and the light is amber, a short, cautious drive to a garage is typically fine, provided you do not delay the actual diagnosis.

Frequently Asked Questions
Why is the Steering Lock Warning Light on in my GMC Hummer EV?
Your GMC Hummer EV turned on the Steering Lock Warning Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Steering Lock Warning Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's moderate priority, respect the warning colour and the car's behaviour. When in doubt with your GMC Hummer EV, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Steering Lock Warning Light on a GMC Hummer EV?
Cost varies widely because the Steering Lock Warning Light can stem from several causes on a GMC Hummer EV. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.
Will the Steering Lock Warning Light reset itself on a GMC Hummer EV?
If the trigger was temporary, a GMC Hummer EV may turn the Steering Lock Warning Light off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
