Polestar 4 Long Range Single Motor Mk1 Reliability

Common Problems

Infotainment and screen glitches

€0 - 8001 of 6

Center display freezes, blackouts, and Apple CarPlay/CarKey disconnections widely reported · more· less

The Android Automotive infotainment in the Polestar 4 has been the most-cited owner complaint since launch. Forum threads document center display resets, 360 camera black screens, persistent orange warning banners (e.g. 'Seat Heating Unavailable') that block touch input, and frequent Apple CarPlay dropouts requiring manual reconnection. Most issues are addressed through over-the-air updates (P4.2.9, P4.2.11, etc.) at no cost, but some owners report symptoms persisting for months. Hardware-related repairs (head unit replacement) would only apply if OTA fixes fail, but are rare under warranty.

Rear-view camera mirror failure

€1,200 - 2,5002 of 6

No rear window — if the roof-mounted camera or digital mirror fails, you lose rearward visibility entirely · more· less

The Polestar 4 has no rear window. Rear visibility relies on a 2.5-megapixel camera mounted in the shark-fin antenna position, feeding a digital rearview mirror. If either fails, the mirror goes dark and the only option is replacement. Few documented failures yet given the car's age, but the architecture means there is no analogue fallback. Water ingress, fog, dirt, and condensation can also temporarily impair the view. Estimated replacement cost combines camera, harness, and mirror unit; under warranty during the 3-year/100,000 km coverage.

Keyless entry and phone-key unreliability

€0 - 4003 of 6

Doors fail to unlock on approach with key fob or digital key, frequent delays reported · more· less

Owners consistently report that the keyless walk-up unlock function is unreliable. Apple CarKey users describe needing to wake the phone manually, and physical key fob behavior is described as 'flaky'. Polestar attributes the issue to sleep-state implementation in the body computer and addresses it via OTA updates. Most owners eventually work around it by using the door handle button or unlock via phone app. Not a safety issue, but a daily frustration on a €60k+ car.

ESC Sport mode power limitation bug

€0 - 04 of 6

Activating ESC Sport mode can leave the motor limited to reduced power until full reset · more· less

Polestar has acknowledged a software issue in the Single Motor variant where activating ESC Sport mode can trigger a persistent power reduction. The car must be left locked and powered off for approximately 20 minutes to reset. No physical damage, but the workaround is annoying and the bug is unresolved as of recent firmware. Worth confirming on test drive whether the latest software version on the car resolves this. Repairs covered by OTA, no cost.

Suspension harshness and bushing wear

€400 - 1,4005 of 6

Stiff ride with reports of premature bushing wear and rattles on early cars · more· less

Several long-term reviews and owner reports describe the Polestar 4's ride as overly firm, with the car amplifying small road imperfections into cabin vibrations despite weighing 2.3 tonnes. A few early-build cars (late 2024 production) have reported premature bushing and link wear, often replaced under warranty. Some owners also note interior trim rattles developing from the constant vibration. Long-term durability of the dampers and bushings is unknown given the car's youth — worth listening carefully on a varied-road test drive.

Haptic steering wheel controls

€0 - 5006 of 6

Haptic buttons for cruise control criticized as unreliable and distracting · more· less

The Polestar 4 uses haptic (touch) buttons on the steering wheel for cruise control and other functions, which reviewers and owners have described as 'incredibly irritating at best and verging on dangerous at worst' because they lack physical feedback. While not a mechanical failure, accidental input is common and many owners report mis-adjusting speed or canceling cruise control unintentionally. Polestar has tweaked sensitivity via OTA updates. No physical fix exists short of redesigned hardware.

Mechanically simple, but software-defined risks dominate ownership

The Polestar 4 Single Motor is mechanically straightforward — single rear motor, fixed-ratio gearbox, no engine or transmission complexity. The 100 kWh battery has an 8-year/160,000 km warranty with 70% capacity guarantee. Almost all reported issues are software-related: infotainment glitches, keyless entry quirks, and assistance system bugs. These are typically resolved via over-the-air updates at no cost, but persistence varies. The architectural choice to remove the rear window introduces a single-point-of-failure risk on the camera mirror system. Long-term mechanical reliability is unknown given the car's age (delivered from August 2024), so buying with substantial remaining factory warranty is strongly advised.

Pre-Purchase Inspection Checklist

General checks

Service history
Verify Polestar dealer service stamps and any software update records.
Tires
Check tread depth, age (date codes), and uneven wear. Rear tires wear faster on RWD.
Battery health (SoH)
Ask seller to show State of Health from Polestar service report. Should be 95%+ on a low-mileage car.
Test drive
Minimum 30 minutes including highway and varied roads to feel suspension behavior and validate driver assistance.

Specific for this vehicle

Verify latest software version installed
Check the software version in the central screen settings. Should be P4.2.11 or newer (as of 2026). Older versions have more bugs.
Test digital rearview mirror and 360 camera
Switch the rearview mirror between camera and mirror modes. Test the 360 camera at low speed. Look for freezing, lag, or black screens.
Test keyless entry repeatedly
Lock the car, walk away, return and try walk-up unlock 5+ times. Delays or failures indicate the unresolved sleep-state bug.

+ 4 more checksShow less

Test Apple CarPlay / Android Auto reliability
Connect a phone, drive for 10 minutes, exit and re-enter. Check whether reconnection is automatic and seamless.
Listen for suspension rattles on rough roads
Drive over speed bumps, broken tarmac, and cobblestones. Listen for knocks from bushings and trim rattles.
Verify ESC Sport mode behavior
If safe to test, briefly activate ESC Sport then return to normal. Confirm full power returns without needing a reset.
Check 12V battery health
Polestar 4 uses a small 12V battery for accessories. Failures cause many spurious warnings. Ask if it has been replaced.

Recalls and Technical Service Bulletins

No major safety recalls issued for the Polestar 4 as of early 2026 Verify with VIN

The Polestar 4 has been free of major recalls so far, but software is updated frequently via OTA. Contact Polestar with the VIN to verify all available updates have been applied and check for any open campaigns.
