In 2026, data suggests that Polestar's 89.3% reliability score is a "high-hardware, low-software" average. While the mechanical platform is solid, owners frequently report early-ownership "digital gremlins."
Here is the list of 5 labels for Polestar Reported Faults & Warranty Fixes:
TCAM Connectivity "Blackout",
Cause: The Telematics and Connectivity Antenna Module (TCAM) is the primary failure point. It manages GPS, LTE, and digital keys. Software bugs or moisture in the "shark fin" antenna can cause a total system loss.
Solution: Most are fixed via a hard reset (disconnecting the 12V battery) or a dealer-installed module replacement. This is almost exclusively covered under the 4-year/50k mile warranty.
Rearview Camera "Lag & Freeze" (Recall),
Cause: A 2025 recall (NHTSA 25V-293) identified that the Google-based infotainment system sometimes fails to prioritize the camera feed, leading to a black or frozen screen when reversing.
Solution: A mandatory software update to re-index the camera signal. For 2026, Polestar is also offering a Snapdragon CPU upgrade to improve the processing speed of these safety visuals.
Propulsion System "Limp Mode",
Cause: Owners report sudden "Propulsion System Service Required" errors. These are often traced to faulty inverter capacitor terminals or software glitches in the Battery Energy Control Module (BECM).
Solution: This is a major warranty repair. Dealers typically replace the entire Inverter Module or perform a deep-level software flash. If the car is immobilized, Polestar's 4-year roadside assistance covers the recovery.
HVAC Damper Motor "Ticking",
Cause: Small plastic gears in the climate control's blend-door actuators can slip or break, creating a repetitive clicking sound behind the dashboard as the car tries to adjust air temperature.
Solution: Technicians recalibrate the motors via service software. If the gear is physically stripped, the actuator is replaced under warranty, though this can be a labor-intensive "dash-out" job.
Axle & Suspension "Knocking",
Cause: A common mechanical complaint involves "clunking" or "clicking" from the front axles or strut bearings, especially during low-speed maneuvers or when reversing.
Solution: Polestar issued a service bulletin to replace strut bearings with upgraded hardware. Axle noise is often treated by lubricating the driveshaft splines or replacing the half-shafts entirely under the powertrain warranty.
