XPeng G9 Performance AWD Mk1

Multiple owners report that the central screen and passenger display can freeze or go black, particularly after the car has been stationary for extended periods. The system then reboots upon startup, losing settings temporarily. The XPeng app (YouTube, Spotify) can crash mid-use. A detailed owner bug log from the Netherlands documents over 20 software-related issues across XMART OS 4.2.1 and 4.3.0, including settings not being stored correctly, incorrect energy consumption displays, and DAB radio producing metallic, over-pitched sound. While most issues are resolvable through OTA updates (XPeng has shipped multiple XOS updates improving stability), persistent bugs may require a dealer visit for a system reset. The 2025+ Turing-based software is reported to be substantially more stable than earlier versions.

The G9 Performance AWD comes standard with dual-chamber air suspension on all four corners. While no widespread failure pattern has emerged yet (the car is relatively new in Europe), air suspension systems in general are a known maintenance concern on any vehicle. Air spring leaks typically manifest as the car sitting lower on one corner overnight, and compressor wear causes slow or incomplete height adjustment. Based on comparable premium EV air suspension systems, repair costs range from approximately €800-1,500 per air spring assembly and €1,000-2,000 for a compressor replacement. The car's manual specifically warns that suspension repair mode must be activated before jacking, as failure to do so can damage the system. XPeng's 7-year warranty covers this if the failure occurs within the warranty period.

Multiple Nordic owners report that the heating element is underpowered compared to competitors. To reach 22 degrees cabin temperature, users need to set the target to 26 degrees. The blower motor runs at high speed but produces poor heating effect. A Danish owner measured air temperature at the vents at only 50-60 degrees Celsius, compared to 70-80 degrees in a Kia EV6. This appears to be a design characteristic rather than a defect, meaning warranty claims are difficult. XPeng has acknowledged the feedback, and later OTA updates have reportedly improved heat pump efficiency somewhat. If the heat pump itself fails, replacement costs are estimated at €500-800 based on comparable EV systems. The issue is most noticeable in Scandinavian winters but rarely a concern in Western European climates.

Owners report several ADAS-related quirks. The ACC system tends to drive aggressively toward vehicles ahead before braking hard, creating an uncomfortable experience for passengers. Below 50 km/h, following distance is perceived as very close. Users also report that ACC initiates hard braking in corners, which becomes dangerous in icy or snowy conditions. The autopilot system positions the car slightly to the right of the lane and slows significantly before curves. XPeng has acknowledged phantom braking as an industry-wide issue and has released OTA updates targeting this specifically. The 2025 Turing AI-based ADAS system (using cameras and 4D mmWave radar instead of LiDAR) is reported to significantly reduce these incidents. Costs are typically zero (resolved via OTA) but occasional sensor recalibration may be needed at a service center.

An early owner reported that the car would die with approximately 25% indicated battery remaining, requiring a system restart. This was traced to a 12V auxiliary battery management issue and was confirmed fixed in XMART OS 4.3.0. Modern EVs rely on the 12V system for control electronics, and if it fails to charge properly from the high-voltage battery, the car can become inoperable. Replacement of the 12V battery costs approximately €200-350, and the issue is typically covered under warranty. The problem appears to have been largely resolved through software updates, but early 2023 builds on older software may still be affected if not updated.

Owners report that the auto high beam system is poorly calibrated, often blinding oncoming traffic or failing to dim appropriately. Interior lighting also resets to full brightness each time the car is turned off and on, despite the user setting it to minimum. These are software calibration issues rather than hardware failures. XPeng has been addressing them through OTA updates, but progress has been incremental. The cost is typically zero (software fix), but if the headlight control module requires replacement, costs could reach €300-400.
