RSB-93-24-001-2: Excessive Cabin Noise and Vibration
from A/C Compressor
Rivian is launching a technical service bulletin for some model year 2022-2024 R1T and R1S vehicles that are
prone to excessive cabin noise and vibration from the A/C compressor. While the vehicle is safely functioning
as designed, some customers might be unaccustomed to the noise of the A/C compressor in an electric
vehicle; such noise is usually not noticeable in vehicles powered by an internal combustion engine. Upon
customer complaint of excessive cabin noise or vibration while the A/C compressor is running, Rivian will
retrofit brackets on the A/C lines, and, if necessary, reroute a harness to reduce noise and vibration in the cabin.
Note: This document supersedes RSB-93-24-001-1. Revision 2 changes the order of installation of the
low pressure line brackets.

Inspection
1. Check the vehicle build date:
• If the vehicle was built before September 16, 2022: Skip to the Reroute Low Voltage Harness
section.
• If the vehicle was built between September 16, 2022 and October 17, 2022: Continue to the next
step.
• If the vehicle was built after October 17, 2022: Skip to the Install Refrigerant Line Brackets section.
2. Remove: Airbag, Knee, LH (refer to service manual procedure 724015010).
3. Inspect for the presence of the highlighted component(s).

• If the component is present: Skip to the Install Refrigerant Line Brackets section.
• If the component is not present: Continue to the next section.

Reroute Low Voltage Harness
1. Remove: Pedal, Brake (refer to service manual procedure 145510010).
2.

RSB-93-24-001-2: Excessive Cabin Noise and Vibration from A/C Compressor, Page 3

3. Remove and discard:

Note: Shown with components removed for clarity.
4. Attach the new clip to Harness, Cowl, as shown.
