How Urgent Is the Service Vehicle Soon Light?
In terms of priority, treat this as a moderate concern on your Polestar 3.

Pay attention to changes in how the Polestar 3 drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.

Is It Safe to Drive With the Service Vehicle Soon Light On?
Whether it is safe to keep driving your Polestar 3 with the Service Vehicle Soon Light on comes down to urgency (moderate) and behaviour. As a rule, if the light is red or flashing, or the Polestar 3 is running poorly, stop somewhere safe and arrange help rather than pushing on.

Professional Mechanic Tips
It is not the same as an oil-service reminder; get it scanned so you fix the real fault rather than resetting a counter.
On many cars the 'service soon' light is just a blown exterior bulb — do a quick lights walk-around on your Polestar 3 before booking a garage.
Frequently Asked Questions
Why is the Service Vehicle Soon Light on in my Polestar 3?
On a Polestar 3, the Service Vehicle Soon Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Service Vehicle Soon 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 Polestar 3, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Service Vehicle Soon Light on a Polestar 3?
There is no single price for the Service Vehicle Soon Light on a Polestar 3; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Service Vehicle Soon Light reset itself on a Polestar 3?
Occasionally, yes — a Polestar 3 can extinguish the Service Vehicle Soon Light by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
