The model(s) and model year(s) listed are a general approximation of the affected VIN list. Refer to the VIN/Bulletin Tracker or Customer/Vehicle profile to determine
applicability of this bulletin for a particular vehicle.

Repair Bulletin: This repair bulletin provides instructions on addressing a possible customer concern regarding the operation of
Tesla vehicles. These instructions should only be performed by trained professionals.

Condition
Certain Model S and Model X vehicles may require a support bracket retrofit to the A/C compressor pipes.

Correction
If a service operation has removed the underhood storage unit, use the opportunity to inspect the A/C compressor
discharge and suction pipes for a support bracket securing the pipes together. If no bracket is present, retrofit the
support bracket between the pipes to reduce the stress on the discharge pipe.
