Inoperable Folding Rear Seat

The 2nd-row bench seat on 2021-2022 Tahoe, Suburban, Yukon and Escalade models features a 60/40 split-folding function. (Fig. 12) On some models, the 60% side of the rear seat may not fold down due to a detached seat cable to the outboard seat release lever.

When reattaching the seat cable, a reinforcement retainer should be installed to ensure proper folding operation. Refer to the service procedure in Bulletin #21-NA-284 for complete instructions.

After removing the rear seat adjustment and recline handles and outer finish cover, inspect the outboard white release lever for damage or missing material. (Fig. 13)

Also verify that the seat cable is disconnected from the release lever. (Fig. 14)

If these conditions are found, install a reinforcement retainer following the steps in the Service Bulletin.

TIP: When disconnecting the inboard lower cable attachment, remove only the cable end fitting. Use care to not disconnect the internal latch springs. Once the cable has been removed, inspect it for damage. If the metal cable strand is frayed or kinked, the cable should be replaced.

The reinforcement retainer should be located against the white release lever. In the correct position, it will bottom out against the edge of the lever. (Fig. 15)

To secure the retainer, drill a hole in the release lever. Use the retainer as a template for the proper location of the hole. Insert the rivet from the service kit to attach the retainer. (Fig. 16) Ensure the rivet shank does not fall into the seat mechanism.

Once the retainer is installed, verify the edge of the retainer is not contacting the metal cable strand (Fig. 17) and that the seat folds freely.
