Polestar 2 Reliability: What UK Buyers Need to Know (2026)

The Polestar 2 is a premium electric fastback built in China — at the Luqiao CMA Super Factory in Zhejiang province — to the same manufacturing standards as the Volvo XC40 Recharge, which shares the same platform and factory. That heritage matters: Chinese long-term owners report 120,000 km-plus without major drivetrain faults, and Sohu Auto owner reviews average 4.69/5.0. The reliability story is not about the powertrain — it is about electronics, software and, in early cars, a single hardware module that has caused disproportionate grief.

Two major UK surveys give very different pictures, and both are worth understanding. What Car?'s 2024 reliability survey placed the Polestar 2 10th out of 20 electric cars, with a score of 89.3% — ahead of the Kia EV6 and Porsche Taycan. Forty-two per cent of owners reported issues, predominantly infotainment and electrical, but almost all were resolved swiftly under warranty. Auto Express Driver Power 2023 paints a darker picture: 69 per cent of first-year owners reported faults, placing the model 71st out of 75 cars for reliability, despite the Polestar brand finishing 2nd overall. The divergence likely reflects the difference between all-age-of-car owners (What Car?) and first-year experience only (Driver Power), and the rapid software improvements Polestar has made. Newer builds, particularly MY23 onwards, appear significantly more settled.

Two formal UK recalls cover early production Polestar 2s. The first affected approximately 700 cars built in 2020: defective tin-coating on inverter capacitor terminals could cause a short circuit, triggering dashboard warnings and driving problems; the fix was a free inverter module replacement. The second covered nearly 2,400 cars from 2021: a software fault in the battery energy control module could cause unexpected power loss; this was resolved by a free software update at a Volvo or Polestar dealership. Both issues are long closed, but buyers of used 2020–2021 cars should verify the recall work has been completed via gov.uk/check-vehicle-recall. A third recall relating to the rearview camera was issued in the United States (27,816 vehicles, May 2025) and Canada for 2021–2025 models; at the time of writing this guide no equivalent UK DVSA notice has been confirmed — buyers should check the government recall database themselves.

Four issues come up repeatedly across UK owner forums and review aggregators. First, infotainment freezes and audio drop-outs — the Android Automotive OS can lock up, requiring a system reset or, in persistent cases, a dealership software update. Second, and the most disruptive, is TCAM failure: the Telematics and Connectivity Antenna Module handles LTE, GPS, Wi-Fi, digital key, app control, and eCall. When it fails, the car may refuse to detect keys, lock charge rates to 6A, and lose all remote services. The module is a shared Volvo component (also used in XC40 and XC90), so it is a known fleet-wide issue rather than a Polestar-specific defect. A soft reset (hold front demister button for 20–30 seconds) resolves minor Stage 1 failures; full hardware failure requires disconnecting both the 12V battery and the TCAM's own 3.6V backup battery, or a module replacement (dealer part HUF8423MS) under warranty. Third, 'Propulsion System Service Required' warnings can appear with or without actual power loss — most are resolved by a software update. Fourth, front suspension knocking — a service bulletin covers strut-bearing replacement with upgraded parts, though UK parts availability has been variable.

The Polestar 2 comes with a 3-year / 60,000-mile vehicle warranty — the shortest in class among Chinese-adjacent EVs sold in the UK. For comparison, BYD offers 6 years / 100,000 miles, Omoda 7 years, and MG 7 years. The warranty is transferable on change of ownership, which is useful for used buyers. The battery warranty is much stronger: 8 years / 100,000 miles with a guarantee that State of Health will not drop below 70%. A 12-year corrosion warranty also applies. Polestar does sell an extended vehicle warranty (1, 2, or 3 additional years) as an insurance product, purchasable while the car is under three years old and has fewer than 60,000 miles. If you plan to keep the car longer than three years, price the extension at purchase — it cannot be added later if those thresholds have passed.

The Polestar 2 has suffered significant depreciation, particularly for 2022–2023 models bought at peak pricing. Forum evidence suggests some 2022 cars lost 40–45% of their value within nine months, and newer 2024 RWD Long Range Single Motor examples were trading under £30,000 by May 2025 against original prices above £45,000. This is driven by broader EV market corrections, rapid model iterations, and Polestar's own price repositioning. The depreciation curve makes used examples compelling value for private buyers, but new buyers should approach PCP residual guarantees with care and consider salary-sacrifice or business leasing where BiK efficiency matters more than outright residual value. Note: the figures cited here are from owner forums and Autotrader observations — they are indicative, not guaranteed trade values.

The Polestar 2's reliability record is better than its early reputation suggests, but it carries two structural risks that buyers must price in. The first is the TCAM module: it is a known, documented weak point that affects a meaningful percentage of owners. Under warranty it is covered; out of warranty it is a dealer job. The second is the short 3-year vehicle warranty — plan for an extended policy from day one if keeping the car past year three. What the car emphatically is not is a drivetrain worry: the Volvo-heritage CMA platform and long-term Chinese owner data point to a fundamentally sound powertrain. My recommendation: buy a 2022 or newer example — the inverter and contactor recalls are long closed on those cars — verify the TCAM history at inspection, confirm no outstanding recalls on gov.uk/check-vehicle-recall, and add the extended warranty at handover.
