Unusual Noise from Engine Compartment During Acceleration
A Tesla Model 3 does not have a traditional engine, so the noise likely originates from the electric drive unit, suspension, or a loose component. The sound when accelerating could indicate a failing drive unit bearing, a loose heat shield, or a suspension issue.
Diagnosis Details
Possible Causes
Drive unit bearing wear or failure, causing a whining or grinding noise under load.
Loose or vibrating heat shield or underbody panel, creating a rattling sound during acceleration.
Suspension component (e.g., control arm bushing) worn, causing a clunk or creak when torque is applied.
