What is the 2007-2014 Chevrolet Silverado 1500 Brake / Fuel Line Corrosion Failure (Galvanized Steel Lines, Salt-Belt)?
The original galvanized-steel brake (and fuel) lines on these trucks lack the modern nylon/PVF anti-corrosion coating, so in cold-weather/road-salt states the lines rust from the outside in and rupture. A brake-line burst causes sudden, often warning-light-free loss of brake pres… Repairs typically run $300-$1,200. Severity: high.
What is the 2007-2019 Chevrolet Silverado 1500 P0700 — Transmission Control System Malfunction from Failed 6L80 TEHCM (or 4L60E Shift Solenoid)?
P0700 is not a specific fault by itself — it is an umbrella/MIL-request code the ECM stores whenever the transmission control module (TCM) detects an internal transmission problem and asks the ECM to turn on the check-engine light. On the Silverado 1500 it almost always appears a… Repairs typically run $300-$1,600. Severity: high.
What is the 2000-2013 Chevrolet Silverado 1500 Engine Oil Cooler Line Failure Causing Rapid Oil Loss at Crimped Hose Fittings?
