What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Headlights are horrible Not effective during rain, did not see a tree in road in time. Had a collision 5k in damages.
Second, my passenger airbag light has been on since September 2024. I was told to replace the sensor the whole seat rail would need replaced and would be over 1000 dollars. Apparently not covered under warranty either. Lastly, god forbid you have to drive West when the sun is going down.
All Safety features stopped working while driving multiple times and loading feature pops up on the display screen. Speakers will go mute randomly, no sound will emit including phone calls.
When the vehicle is off the windows will come down on their own! This has occurred on 4 difference instances. One dealership indicated the "fix" the situation; however, they never replaced the parts which were required for the fix. A second dealership would not perform a diagnostic.
Multiple instances of the vehicle emergency collision avoidance system responding to a parked car or a car stopped in a left turn lane (i.e. waiting at a light). 5X+ The car audio alarm goes off, and the vehicle abruptly brakes while moving in traffic.
Passenger Airbag does not turn on when someone who weighs 100 pounds or less occupies the front passenger seat. This issue also occurs on my 2024 Subaru Crosstrek Vin # [XXX] . IT also occurred on the loaner car the dealer gave me which was a 2025 Subaru Crosstrek.
When my wife (who weighs under 99 pounds) is seated in the front passenger seat the indicator light for the passenger airbags does not always show that the airbags are on. When I sit in the front passenger seat the indicator light always shows that the airbags are on.
