Used Polestar 4: what to buy, and the truth about the no-rear-window question

For most buyers the pick is the Long Range Single Motor, and on the used market a 2024 car now sits at roughly £30,000-£40,000. That is a remarkable drop from the near-£60,000 it cost new barely a year earlier, and it's the whole used Polestar 4 story in one line: a genuinely desirable, beautifully made, long-range electric coupe-SUV that has depreciated so hard that it's become a used bargain. The Single Motor is the one to have over the 544bhp Dual Motor because it goes furthest on a charge (a claimed 385 miles, one of the best in the class), costs less to buy and insure, and 272bhp is ample. The Dual Motor is thrillingly quick but you pay for it in range, efficiency and insurance.

There are two things every buyer must weigh, though, and they're connected. The Polestar 4 has no rear window, with rearward vision handled entirely by a roof-mounted camera feeding a digital mirror. And Polestar has a documented history of rear-view-camera software recalls on the Polestar 2. On a car where the camera is your only rear view, that deserves real attention. The rest of this piece covers the versions, the no-rear-window reality, what the reliability data does and doesn't tell us, and what to check before buying.

Which version, and what you're buying

The Polestar 4 launched in the UK at the start of 2024, with first deliveries from around August 2024, so the used market is 2024 and 2025 cars. It sits between the Polestar 2 and the larger Polestar 3 in size and price, and it's hard to pigeonhole: a low-slung, coupe-roofed five-seater that Polestar calls an SUV but really drives like a raised sports saloon. It's built on Geely's SEA platform, shared with cars like the Zeekr 001 and Lotus Emeya, and assembled at Hangzhou Bay in China.

Both versions use the same battery, around 100kWh gross and 94kWh usable:

• Long Range Single Motor is rear-wheel drive, 272bhp, 0-62mph in about 7 seconds, and a claimed 385 miles WLTP (expect 300-plus real-world, and reviewers have seen close to 370 in gentle use). The range champion and the value pick.
• Long Range Dual Motor adds a front motor for 544bhp and a 3.7-second 0-62mph time, dropping the claimed range to 367 miles (around 340 real). A Performance Pack adds Brembo brakes, active ZF dampers and bigger wheels, sharpening it up at a small further cost to range and ride comfort.

One thing to note for the money: the Polestar 4 is a 400-volt car with a 200kW DC charging peak (a 10-80% charge takes around half an hour, settling near 135-140kW in practice). That's fine, but it's no longer class-leading, and notably the larger Polestar 3 has already moved to 800 volts while the 4 hasn't. The flip side is a strong 22kW AC onboard charger and that genuinely long single-motor range. The cabin is lovely, materials a clear step above the Polestar 2, with a 15.4-inch Android Automotive system (Google built in) and a panoramic glass roof. Rear space is excellent, helped by the missing rear window, more on which now.

The no-rear-window question

This is the thing everyone asks about, so here's the honest version. Instead of a rear screen, the Polestar 4 has a camera mounted high on the roof feeding a digital rear-view mirror. The upside is real: it frees up rear headroom and gives back-seat passengers a genuinely limousine-like amount of space and light under that glass roof, and the camera view isn't blocked by headrests or passengers.

The downsides are also real and worth test-driving for properly. The digital mirror takes acclimatisation, your eyes have to refocus from the road to a screen at a different focal distance, and some people never fully get on with it, finding it disorienting in town or at night. You cannot swap it for a conventional mirror, because there's no glass behind it to look through. So before buying, spend real time with it: a quick forecourt glance isn't enough. Drive it in traffic, reverse it, try it at dusk. Either it clicks for you or it doesn't.

And there's a reliability dimension that ties straight into the next section: if that camera or screen fails, you have no rear view at all. That raises the stakes on Polestar's software track record more than it would on a normal car.

Reliability: what the data does and doesn't tell us

The Polestar 4 is too new for meaningful UK reliability surveys of its own. And here's a point worth being straight about: for the BYD Seal we leaned on China's large home-market owner-quality data, but that approach doesn't transfer here. Although the Polestar 4 is built in China, Polestar barely sells there, the company's own reporting excludes China from its retail network, so there's little Chinese owner data on this car to draw on. We're not going to pretend otherwise. Instead, the useful signals come from three places.

The Polestar 2's track record. Polestar's only model with real history is broadly reassuring on hardware but patchy on software. In What Car?'s reliability survey the Polestar 2 has landed mid-table among EVs, ahead of some premium rivals, with most reported faults being infotainment and electrical niggles that were fixed under warranty. The recurring themes were connectivity-module failures (knocking out the app, GPS and digital key until replaced), occasional software-related power-loss or limp-mode warnings, and a front strut-bearing knock addressed by a service bulletin. Annoyances rather than disasters, and mostly warranty work.

The rear-view-camera recalls. This is the one to take seriously given the Polestar 4's design. Polestar recalled tens of thousands of Polestar 2 cars over a software defect that could stop the rear-view camera image displaying, and it took more than one attempt to resolve. The Polestar 4 makes a camera the only rear view there is, so confirm the digital mirror works flawlessly and the car is on current software before buying.

The sibling and platform picture. The closely related Polestar 3 has had several recalls in its first model years, mostly software-fixable, and owners report a thin service network and sometimes long waits for parts or software guidance. On the positive side, the SEA platform underneath the 4 also sits beneath high-volume Chinese cars like the Zeekr 001 (itself a five-star Euro NCAP performer), the battery is a CATL unit, and the engineering links to Volvo show in the safety: the Polestar 4 scored a full five stars at Euro NCAP in 2025.

The honest bottom line: the Polestar 4 should be mechanically sound, and it's demonstrably safe, but it's a first-year car from a brand whose weak spot is software, sold through a small service network. Buy with that in mind.

Other known issues to verify

Everything runs through the touchscreen. Mirror adjustment, the glovebox, even the rear fog light live in the 15.4-inch screen, with very few physical controls. It's a steep learning curve and can be distracting on the move. Make sure it suits you.

Ride can be firm. Especially on Dual Motor cars with the Performance Pack and big wheels, the 4 can thud over poor surfaces. The Single Motor on smaller wheels rides better.

Service network and downtime. Polestar's UK service network is small. A major fault can mean a longer tow and a longer wait than with an established brand. Check where your nearest service point is and ask about loaner-car arrangements.

Charging speed. The 200kW, 400-volt setup is fine but not exceptional for the money, so on long trips the top-ups are a little slower than the best rivals.

Battery health shouldn't be a worry on cars this young, and the CATL pack plus an eight-year warranty cover it. There's simply not a long reliability record yet, which is the honest caveat for any early Polestar 4.

Pre-purchase checks specific to the Polestar 4

In addition to the usual used-EV checks in the 14-point checklist:

• Test the digital rear-view mirror and camera thoroughly. This is the single most important check. Confirm a clear, lag-free image in daylight, at night and when reversing, and that the car is on the latest software. Spend real time deciding whether the system suits you, because you can't change it.
• Run a VIN recall and software check. Confirm any camera or software campaigns are completed and the car is fully updated.
• Confirm remaining warranty. Polestar's three-year/60,000-mile vehicle warranty and eight-year/100,000-mile battery warranty transfer with the car. Check how much is left against this car's date and mileage.
• Check service-point proximity. On a small network this matters more than usual; factor a realistic distance and downtime into the decision.
• Test charging on AC and DC. Expect a 200kW peak at best; confirm it charges cleanly.
• Live with the touchscreen on the test drive to be sure you can operate the essentials comfortably.
• Run a battery health check if you can. See the battery state of health guide.

What a used Polestar 4 should cost in mid-2026

The used market is young but surprisingly well-stocked (a couple of hundred cars nationally), because heavy depreciation has put a lot of nearly-new examples up for sale. Treat these as indicative; values are still moving. Approximate retail pricing for clean, low-mileage cars:

Year	Variant	Price band
2024	Long Range Single Motor (RWD)	£30,000-£40,000
2024	Long Range Dual Motor (AWD)	£35,000-£45,000
2025	Long Range Single Motor (RWD)	£34,000-£44,000
2025	Long Range Dual Motor / Performance	£38,000-£52,000

For context, the Polestar 4 launched at £59,990 (Single Motor) and £66,990 (Dual Motor), so used buyers are routinely saving £20,000 or more on a one- to two-year-old car. That depreciation has been brutal for original owners, among the steepest in the class, but it's exactly what makes the used 4 such strong value, provided you're comfortable being an early owner of a young model from a brand still building out its UK presence.

What it competes with

The Polestar 4 straddles segments, so its used rivals are a broad set in the £30,000-£45,000 range:

• Tesla Model 3 and Model Y (2022-2024), see our Model Y guide. Better efficiency, range and charging access, less design flair, and the obvious value benchmark. (A Model 3 guide is on the way.)
• BMW i4, see our i4 guide. A similar footprint, the keen-driver's choice, with a stronger reliability record and a conventional rear window.
• Polestar 2 (2023+), see our Polestar 2 guide. The smaller, cheaper, more proven sibling if the 4's quirks or price don't appeal.
• Hyundai Ioniq 5 / Kia EV6, see our Ioniq 5 guide and EV6 guide. E-GMP cars that charge faster on 800 volts and offer more conventional packaging.
• Hyundai Ioniq 6, Porsche Macan Electric and Audi Q6 e-tron are the other natural cross-shops on price and concept; none has a Compass EV guide yet.

The Polestar 4's case rests on standout design, a lovely cabin, genuinely long single-motor range, a five-star safety rating, and used pricing that now looks like a lot of premium car for the money. Against it: the polarising no-rear-window setup, a software-reliant brand with a thin service network, only-fair charging speed, and the unknowns of a first-year model. For a buyer who tries the digital mirror and loves it, and who values the design and the value over charging speed and brand familiarity, it's a compelling used buy.

Frequently asked questions

Is the Polestar 4 reliable? There isn't enough UK data yet to say definitively, and unusually we can't lean on Chinese home-market data either, because Polestar barely sells in China despite building the car there. The read-across from the Polestar 2 and 3 is that the hardware is generally sound but software is the weak spot, with infotainment, connectivity and camera glitches the main reported issues, mostly fixed under warranty. The car is demonstrably safe (five-star Euro NCAP). Buy one that's fully updated, with warranty remaining and a service point within reach.

Is the no-rear-window thing actually a problem? It depends entirely on you. The digital mirror frees up space and isn't blocked by passengers, but it takes acclimatisation and some people never love it, particularly at night or in town. You can't swap it for a normal mirror. Test it properly before buying. And because the camera is your only rear view, confirm it works perfectly and is on current software, given Polestar's history of camera-software recalls on the Polestar 2.

Single Motor or Dual Motor? Single Motor for most. It has the longest range, costs less to buy and insure, and 272bhp is plenty. The Dual Motor is seriously fast, but range, efficiency and running costs all take a hit.

Why is it so cheap used? Steep depreciation, among the worst in the class, driven by the wider used-EV slump and Polestar's own pricing. That's painful if you bought new but excellent if you're buying used now: a near-£60,000 car for £30,000-£40,000, with the warranty still running.

How's the range and charging? The Single Motor's 385-mile claim translates to comfortably over 300 real-world miles, which is genuinely strong. Charging peaks at 200kW on a 400-volt system, fine for occasional rapid top-ups but slower than 800-volt rivals on a long run.

Does the warranty transfer if I buy used? Yes. The three-year/60,000-mile vehicle warranty and eight-year/100,000-mile battery warranty (with a 70% capacity guarantee) stay with the car. Confirm the remaining term against the specific vehicle.
