2024 Subaru Solterra

A manufacturing defect can cause the wheel hub bolts to loosen during driving, potentially resulting in wheel separation. This serious safety issue prompted a major recall. Affected vehicles may exhibit a knocking or clicking noise from the wheels, vibration at speed, and in extreme cases, a wheel could detach while driving.

Subaru issued recall WRF-22V for hub bolt loosening. Dealers will inspect and retorque or replace the hub bolts on all four wheels free of charge. During the initial recall period, Subaru requested that affected owners stop driving their vehicles until the repair was completed. Verify your VIN on the NHTSA recall site.

Some owners report inconsistent DC fast charging behavior, including sessions stopping prematurely, failing to initiate, or charging at significantly reduced speeds. The CCS charging port may not establish communication with certain charging networks. Cold weather exacerbates these issues as the battery pre-conditioning system may not adequately warm the battery for fast charging.

Ensure the vehicle software is updated to the latest version, as Subaru and Toyota (shared platform) have released multiple OTA updates to improve charging reliability. Pre-condition the battery by driving for at least 15 minutes before fast charging in cold weather. Report specific charging station incompatibilities to Subaru customer service for investigation.

The Solterra's infotainment system experiences software bugs including touchscreen lag, frozen screens, slow boot times, and intermittent loss of connected services. Apple CarPlay and Android Auto can disconnect unexpectedly. The onboard navigation may lose GPS position or provide incorrect routing. These issues reduce daily usability.

Accept and install all available OTA software updates, which Subaru has pushed regularly to address infotainment issues. Perform a system reset if the screen freezes (press and hold the power button). If persistent issues remain after updates, the infotainment control module may need replacement at the dealer.

The displayed range estimate can be significantly inaccurate, particularly in cold weather, at highway speeds, or when using the HVAC system. Owners report the range dropping much faster than expected, with the actual range being 20-30% less than the displayed estimate in winter conditions. This range anxiety concern is amplified by the Solterra's modest EPA range.

Use the climate pre-conditioning feature while plugged in to warm the cabin without using battery range. Set the HVAC to eco mode and use seat heaters instead of cabin heat in cold weather. Drive in Eco mode for maximum range. Subaru software updates have improved the range estimation algorithm over time.

Some owners report the windshield wiper system developing faults, including the wipers not parking correctly, intermittent operation, or a wiper motor that fails entirely. Error messages related to the wiper system may appear on the instrument cluster. The issue appears to be related to the wiper motor control module.

Have the dealer diagnose the wiper system with the diagnostic computer. A wiper motor control module software update may resolve intermittent issues. If the wiper motor has failed, it needs to be replaced. This is a safety-critical system and should be addressed promptly. Check for applicable recalls or service campaigns.
