Polestar 3 Long Range Dual Motor Mk1

The Polestar 3 runs on an Nvidia-based central computing platform that Volvo developed for the SPA2 architecture. Early builds suffer from frequent infotainment crashes: the screen goes black mid-drive, apps freeze, audio cuts out while the track timer continues running, and OTA updates sometimes fail or reset saved preferences (radio presets, driver profiles, lane departure settings). Forum reports describe crashes occurring on nearly every journey for some owners. A soft reboot of the center display or a full power-cycle of the vehicle typically resolves the immediate symptom. Polestar has issued multiple over-the-air software updates to address stability, and later 2025/2026 builds run notably cleaner software. The 2026 model year brings a new dual-Orin central computer, and existing 2025 models are being retrofitted with this hardware for free. The direct cost is typically zero under warranty, but out-of-warranty diagnostic and software intervention at a dealer runs around €200-500.

A small number of Polestar 3 owners have reported complete onboard charger failure, where the car no longer accepts AC power from a home wallbox or public Level 2 charger. DC fast charging typically still works. The replacement part has been quoted at approximately £1,680 (around €1,950) before labor, though this is covered under the factory warranty. The bigger practical problem is availability: some owners report waiting 30 or more days for the replacement part to arrive at the dealer, during which the car may be out of service. A loaner vehicle is often provided but coverage varies by market. This issue has also been documented on the closely related Volvo EX90. Some less severe cases involve the car drawing far less current than expected (14 A instead of 32-48 A), effectively halving overnight charging speed.

The Polestar 3 relies heavily on phone-based digital keys for lock/unlock and engine start. Many owners report that the approach unlock feature works perfectly for weeks, then stops without explanation. The NFC key tag backup can also stop responding. Bluetooth interference, Wi-Fi conflicts, phone OS updates, and the car's own TCAM (telematics module) going to sleep have all been identified as contributing factors. The workaround is to always carry the physical key card as backup. Software updates have improved reliability, but the system remains inconsistent for many owners. Out-of-warranty TCAM resets or module replacement could cost €200-300, though most fixes are software-based and free under warranty.

The Polestar 3's Pilot Assist (adaptive cruise with lane centering) frequently disengages on early-build cars, displaying 'Driver support failure' or asking the driver to visit a service center. The system tends to struggle around large vehicles and on curving highway sections. Parking sensors and cameras also throw intermittent errors. These are software-related sensor interpretation issues rather than hardware failures. A system restart or infotainment reboot typically clears the warnings. Polestar has addressed many of these in successive OTA updates, and an infotainment system reset has been reported to significantly improve Pilot Assist behavior. Under warranty, diagnostic sessions are free. Out-of-warranty, expect €200-500 for a dealer software diagnosis and update.

The dual-motor Polestar 3 comes with standard active air suspension. Some owners have reported suspension fault warnings, though investigation has typically revealed software glitches or loose damper solenoid connector cables rather than actual air spring or compressor failures. The car is too new for widespread mechanical air suspension failures to have surfaced. However, air suspension systems carry inherent long-term risk. Based on comparable luxury EV SUVs, an air spring replacement costs around €1,000-1,200 per corner, and a compressor replacement runs €800-1,300 including labor. These components typically become wear items after 80,000-120,000 km on comparable vehicles.

A recall (RP1063) covering approximately 9,966 vehicles worldwide addresses moisture ingress in a connector housing between the engine bay and front bumper cable harnesses. Corroded internal pins can cause parking brake engagement issues, start-up difficulties, loss of power steering assist, or multiple warning messages. This was filed with European safety authorities in July 2025. Loss of power steering in a 2,579 kg SUV is a serious safety concern. The repair involves replacing the affected connector housing and is covered under the recall at no cost. For vehicles where the recall was not completed or for similar connector issues outside recall scope, parts and labor run €400-800.
