Unusual Noise Diagnosis for 2021 Tesla Model Y
A persistent unusual noise from an unknown location in a 2021 Tesla Model Y could stem from several sources, including suspension components, electric drive unit, or interior trim. Given the all-electric drivetrain, the absence of engine noise makes abnormal sounds more noticeable.
