Summary
TECHNICAL SERVICE BULLETIN: BRAKE BOOSTER PUSHROD ADJUSTMENT (SC377) - This bulletin provides information for adjusting the brake booster pushrod on certain 2027MY Telluride (LQ2) vehicles produced from January 2, 2026, through April 22, 2026. The brake booster pushrod may be improperly adjusted. As a result, following certain low-speed automatic braking events, a small amount of residual brake pressure may temporarily remain after systems such as Reverse Parking Collision-Avoidance Assist (PCA-R) or Rear Cross-Traffic Collision-Avoidance Assist (RCCA) automatically apply the brakes to help prevent a collision. After the automatic braking is canceled, the driver may experience the brakes lightly dragging for a short time. This condition does not affect braking performance or stopping distance.

Owners of these vehicles have filed 3 complaints in the brakes category.
