If you own a Polestar in the United States, your warranty, genuine parts, service visits and over-the-air software updates continue. What ends is new Polestar sales. The Commerce Department denied Polestar the authorization it needed under the Connected Vehicle Rule, so US sales stop with 2026 model-year cars. Polestar says it will not appeal. This field guide explains what changes for existing owners, what stays the same, and what to lock down in writing before you buy, trade or sell a Polestar.
What the Connected Vehicle Rule changed for Polestar
The Connected Vehicle Rule targets connected software and hardware tied to China and Russia. It does not ban cars already on US roads. It sets limits on what a manufacturer may sell in the US, and it phases in. The software restrictions apply first, starting with the 2027 model year. The hardware requirements take full effect later, around the 2030 model year.
Volvo, Polestar's sister brand, received authorization to keep selling in the US. Polestar did not. That difference is why Polestar is the one brand leaving the market under this rule, while its sister brand stays. For a driver, the practical result is simple: no new Polestar 3 or Polestar 4 will arrive on US lots after the 2026 model year, and remaining inventory is sold off until it runs out.
Read the rule as a sales restriction on new vehicles. It is not a recall, and it does not turn your car into a different vehicle overnight. Your registration, title and insurance stay exactly where they were.
Does a Polestar still get warranty and service in the US?
Polestar has said it will honor warranties on vehicles already sold in the US. Warranty coverage follows your car and your original purchase date, not the brand's sales status. Keep your original warranty booklet and the purchase or lease paperwork, because those documents set the term you are working under.
Polestar also says it will supply genuine parts under its US Polestar Promise program. Its US service network is still in operation, with roughly 32 retailers. Some of those locations may shift toward service work as new-car inventory runs out. That shift is normal, but it means a service center you visit today could change its role later.
Check your warranty terms on your own paperwork, not in a forum post. If your car is under a powertrain or battery warranty, write down the expiration date and the mileage limit now. You will need both if a dealer later questions coverage.
Will over-the-air software updates keep coming?
Polestar says over-the-air updates continue for cars already in owners' hands, so connected features and fixes should keep arriving. That is the most important point for a daily driver, because many Polestar functions depend on software rather than on a dealer visit.
Here is a short example. Imagine you own a 2025 Polestar 4 in Atlanta and you use it for a 60-mile round trip to work. A software fix pushed over the air might clear a warning or change how a driver-assist feature behaves. If the update channel keeps working, you get the fix without a shop visit. If it stalls, you need a dealer appointment, and that is where a written service commitment matters.
Software is the area where sources are least specific. The reports I checked do not say how long the update channel will be supported for each model. Ask your dealer for that answer in writing rather than assuming it.
What to get in writing from your Polestar dealer
Verbal assurances from a sales desk are easy to forget, and the dealer you talk to today may not be the one who services your car in three years. Ask for the following documents or emails and file them with your purchase papers.
- Written confirmation that your local dealer will operate as an authorized service center for your model.
- The warranty terms for your specific vehicle, including the expiration date for the basic and powertrain coverage.
- A written description of how over-the-air updates will continue for your model and VIN.
- How long your local service point expects to stay open as new-car sales wind down.
- The name of the parts contact or service manager, with a direct email or phone number.
Keep these records in one place. A single digital folder works, and so does a service log that lists each visit, mileage and invoice.
Buying a used Polestar now: what to check first
Discounts on remaining new Polestar 3 and Polestar 4 inventory are often steep, and they tempt buyers who want a new car without the usual wait. Before you sign, treat the purchase as a used-car decision with a short support horizon. Ask what the warranty covers after you take delivery and how long the local service point will be staffed.
Run a VIN check before you commit to any used Polestar. Use the CarDiary VIN check at https://www.car-diary.net/en/check-vin to review the vehicle history you can access. Then check open recalls directly with the National Highway Traffic Safety Administration's recall lookup at nhtsa.gov, using the VIN. An open recall that a dealer has not completed is a bargaining point and a safety issue.
Ask for the full service history. A car with two service visits in its first two years and a clear invoice trail is easier to support than one with gaps. Resale value for a brand leaving the US market is less predictable, and the sources I checked do not settle that question. Price the car as a used car with uncertain resale, not as a model with a guaranteed trade-in value.
Mistakes owners make when a brand leaves the market
The most common mistake is assuming the warranty ends with the sales stop. The rule ends new sales, and Polestar says it will honor warranties on cars already sold. Confirm your own dates instead of relying on that general statement.
The second mistake is waiting on a service appointment until a problem gets serious. When a dealer network shrinks, appointment slots fill faster. Book routine maintenance on time, and do not let a warning light sit for weeks while you wait for an opening.
The third mistake is keeping records only in an email inbox or a glovebox folder. A dealer change, a new owner or a claim can all require invoices and dates that were never filed together. Build the file now, while every document is still easy to get.
CarDiary works well for this job: a digital vehicle log that replaces a shoebox of receipts, with warranty expiration dates, service visits and the next due date kept in one place. It is a personal record, not an official register, so it does not replace Polestar's warranty booklet or the dealer's invoice.
Polestar owner questions answered
Does the Connected Vehicle Rule ban my Polestar from US roads?
No. The rule limits what a manufacturer may sell in the US, and it phases in by model year and component type. Your registered car remains legal to drive under your state's rules.
Will my Polestar still get warranty repairs after 2026?
Polestar says it will honor warranties on cars already sold in the US. Check your own warranty terms and expiration dates on your original paperwork.
Can I still get genuine parts for a Polestar?
Polestar says it will supply genuine parts under its US Polestar Promise program. Ask your service center to confirm parts availability for your model in writing.
Should I buy a remaining new Polestar at a discount?
Only if you accept a shorter support horizon and uncertain resale. Get the written service and update commitments first, then compare the discount against those risks.
