⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Ensure the vehicle is secured before performing any inspections or repairs.

Symptoms

•Whirring noise when accelerating
•Possible decrease in acceleration performance
•Unusual vibrations felt through the floor or steering wheel
•No warning lights illuminated on the dashboard
•Noise may change with speed or load

Diagnostic Steps

1
Inspect the drive unit and electric motor for any signs of wear or damage.
2
Check for loose or damaged components in the drivetrain, including mounts and couplings.
3
Scan the vehicle's onboard diagnostics using a Tesla-approved tool for any error codes.
4
Verify the condition of the tires, as uneven wear can produce noise during acceleration.
5
Listen for the noise in different driving conditions (e.g., straight vs. turning).

Solution
