Some Subaru Outback owners report experiencing slow acceleration after turning, which may persist despite multiple repairs. This issue can be attributed to several factors, including a dirty air filter that restricts airflow and negatively impacts engine performance, leading to decreased acceleration and increased fuel consumption. Additionally, problems with the knock sensor may affect low RPM acceleration, further compromising the vehicle's performance after a turn. A clogged catalytic converter is another potential culprit, as it can cause hesitation and poor acceleration, particularly noticeable after making a turn. Furthermore, differences in tire or wheel size, gear ratio, and drive by wire lag may also contribute to the sluggish acceleration. It is advisable for owners to have a thorough inspection of these components to identify the root cause of the slow acceleration issue.
