Service bulletin TSB_ELE434

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

TECHNICAL SERVICE BULLETIN: SERVICE ACTION: SBCM SOFTWARE LOGIC IMPROVEMENT (SA658) - This bulletin provides information to upgrade the Side Body Zone Control Module - Driver ‘SBCM_DRV’ and Side Body Zone Control Module - Assist ‘SBCM_AST’ systems software on certain 2027MY Telluride (LQ2a) and 2027MY Telluride Hybrid (LQ2a HEV) vehicles produced from March 13, 2025 through August 27, 2025. Some of the affected vehicles may exhibit a popping noise from one or both outside sideview mirror(s) after the auto fold/unfold function is enabled and the vehicle is locked. This condition is caused by the SBCM sending an additional fold command after the mirrors have already completed the folding operation. This condition does not affect the ability of the mirror to fold or unfold.
