Exhaust leak identification and cabin safety protection on the 2023 Chevrolet Blazer are governed by exhaust gas pressure, acoustic noise detection, and emission sealing components.
How to Fix It:
-
Listen for Unusual Noise: Identify any loud ticking, roaring, or tapping sounds originating from under the hood or vehicle floor during acceleration.
-
Check for Soot Marks: Look for black carbon soot deposits around exhaust manifold joints, pipe flanges, and connection points.
-
Replace Damaged Gaskets: Install new exhaust gaskets or replace compromised pipe sections immediately to prevent harmful fumes from entering the cabin.
