Toyota Sienna air noise while driving and poor performance of hands-free phone due to insufficient insulation on Toyota Sienna

Some Toyota Sienna owners report experiencing air noise while driving, particularly a whine at speeds of 60 KM/h and above, which may stem from the engine rather than wind. Additionally, a clogged air filter can lead to poor engine performance and noise during acceleration due to restricted airflow affecting the fuel-air mixture. Furthermore, some owners have noted poor performance of the hands-free phone system, potentially linked to insufficient insulation, resulting in sound quality or connectivity issues. It is crucial to address these concerns promptly to maintain optimal performance and comfort, and seeking professional inspection may help identify and resolve the underlying problems.
