Rivian Bulletin Addresses B-Pillar Rattle on R1T and R1S

If your Rivian R1T or R1S develops a rattle from the B-pillar area while driving on rough roads, Rivian has issued a technical service bulletin addressing the problem.

Rivian bulletin RSB-93-26-002-1 applies to certain 2022 through 2026 R1T and R1S vehicles that may produce an audible rattle around the B-pillar when traveling over uneven or rough road surfaces.

According to Rivian, the repair involves applying anti-rattle tape near both first row seat belt retractors.

The bulletin covers certain vehicles built approximately between May 2022 and November 2025, although applicability is vehicle specific.

What Is the B-Pillar Rattle?

Rivian describes the condition as an audible rattle originating from the B-pillar area while driving on rough road surfaces.

The B-pillar is the structural pillar located between the front and rear doors.

On the R1T and R1S, the first row seat belt retractors are located in this general area, and Rivian's repair procedure focuses on components surrounding those retractors.

The bulletin does not describe a seat belt malfunction. Instead, it is categorized under Rivian's Noise, Vibration and Harshness vehicle system.

Which Rivian Vehicles Are Covered?

RSB-93-26-002-1 applies to certain vehicles within the following ranges:

The bulletin applies to vehicles in the United States and Canada.

Being within these model years or approximate build dates does not automatically mean every R1T or R1S is affected.

Rivian instructs service personnel to use its TSB Guide Dashboard to determine whether the bulletin applies to a specific vehicle.

How Rivian Confirms the Rattle

Rivian begins the procedure with a road test rather than immediately disassembling the interior.

A technician sits in the second row on the side where the customer reports the noise while another technician or the customer drives the vehicle.

When the rattle occurs, the technician holds the suspected B-pillar area.

If holding that area causes the noise to stop, Rivian instructs the technician to continue with the repair procedure.

If the noise continues while the area is being held, Rivian says the bulletin is not applicable and the procedure should be discontinued.

What Does the Repair Involve?

The ultimate fix sounds simple: install anti-rattle tape.

Getting to the location where the tape must be installed, however, requires considerably more work.

Rivian instructs technicians to perform the repair on both sides of the vehicle.

The procedure includes removing lower B-pillar trim and loosening or removing components around the front seats and seat belt retractor areas to gain access.

The bulletin specifies several precisely cut pieces of anti-rattle tape that are installed around the areas near the first row seat belt retractors.

Rivian's illustrations show tape being placed at contact points around the B-pillar structure where components may interact and generate the rattle.

The Repair Requires Access Around the Seat Belt Retractors

The bulletin makes clear that this is more involved than simply adding felt tape to an exposed trim panel.

Rivian instructs technicians to unbolt both first row seats and disable the vehicle's 12 volt power before accessing components around the seat belt retractors.

After disabling 12 volt power, the technician must wait at least one minute for the airbag system electrical circuits to discharge before disconnecting or handling the affected component.

This safety step is particularly important because the repair takes place around seat belt and supplemental restraint system components.

Once access is available, Rivian instructs technicians to clean the specified surfaces using alcohol wipes or rubbing alcohol before applying the anti-rattle tape.

Rivian Applies the Fix on Both Sides

One notable detail in the bulletin is that Rivian instructs technicians to perform the repair procedure on both sides of the vehicle.

That is true even though the original complaint may appear to originate from only one B-pillar.

Rivian's labor coding reflects this approach. The repair labor code specifically describes applying anti-rattle tape near the left and right first row seat belt retractors.

This suggests the service procedure is intended to address the corresponding contact areas on both sides once the bulletin has been confirmed as applicable.

Why This Rattle Can Be Difficult to Track Down

Interior rattles can be particularly frustrating because noise can travel through trim panels and structural components.

A sound that appears to come from one part of the cabin may actually originate from a nearby mounting point or hidden component.

That is why Rivian's diagnostic procedure relies on physically holding the suspected B-pillar area while the noise is occurring.

If the sound immediately stops, the technician has a stronger indication that the bulletin applies.

If it does not, Rivian instructs the technician to stop this procedure rather than continuing with unnecessary interior disassembly.

Is This a Recall?

No. Rivian identifies RSB-93-26-002-1 as a Technical Service Bulletin.

The bulletin provides technicians with a diagnostic and repair procedure for vehicles experiencing the specific B-pillar rattle described by Rivian.

It does not mean every 2022 through 2026 R1T or R1S has the condition.

Rivian also instructs service personnel to confirm whether the bulletin applies to the individual vehicle through its TSB Guide Dashboard.

What Should R1T and R1S Owners Do?

If you hear a rattle that seems to originate around the B-pillar while traveling over rough pavement, it can be helpful to document when and where the sound occurs.

Things worth noting include:

• Whether the noise comes from the driver or passenger side
• Whether it occurs only on rough pavement or also on smooth roads
• Whether the sound changes when a passenger applies pressure to the B-pillar trim area
• Whether the rattle occurs consistently over the same type of road surface

If the symptoms match Rivian's description, contact Rivian Service and reference RSB-93-26-002-1.

Rivian Service can determine whether the bulletin applies to your specific vehicle and perform the road test and inspection procedure.

EV Outdoors Takeaway

RSB-93-26-002-1 gives Rivian owners something useful to reference for a complaint that could otherwise be difficult to reproduce or diagnose.

Rivian has identified a specific B-pillar rattle that can occur on certain R1T and R1S vehicles when driving over rough road surfaces.

The diagnostic procedure is straightforward: reproduce the noise and apply pressure to the suspected B-pillar area. If the sound stops, Rivian proceeds with the repair.

The repair itself is more involved than the phrase "anti-rattle tape" might suggest because technicians must gain access around the first row seat belt retractors and perform the procedure on both sides of the vehicle.

For owners of affected 2022 through 2026 R1T and R1S vehicles, this bulletin provides a documented Rivian repair path for a B-pillar rattle that might otherwise be difficult to isolate.
