Most semi breakdowns don’t come out of nowhere. They start with small, ignored issues in cooling, CAC, sensors, DEF, EGR, and wiring. This guide walks through the 10 most overlooked maintenance items, how they fail, what they cost, and how to catch them before they turn into road

On modern semis, a bad turbo rarely fails alone. It spikes soot, kills regens, cracks DOC and EGR coolers, overloads SCR, and wipes out sensors. This guide shows how the cascade works, what it costs, how to catch it early, and where TruckProtect fits into the risk equation.

Most aftertreatment failures are caused by how a truck is driven, not just parts. This guide shows drivers the habits that cut soot, improve regens, protect DPF, DOC, SCR, EGR, and turbo life, and how TruckProtect fits in when inevitable high mile failures still show up.
