CP4 Fuel Pump Secret Fire Danger Hidden in Silverado Sierra—Lawsuits Building Now The Chevrolet Silverado Sierra has long been a favorite among truck enthusiasts and professionals alike, celebrated for its power, durability, and versatility. But beneath its rugged exterior and tough-eval performance lies a hidden safety risk that’s now coming under intense scrutiny. Reports suggest that CP4 fuel pump units—installed in select Silverado Sierra models—may secretly pose a fire hazard, triggering a wave of growing concern and, more recently, lawsuits. ### The Hidden Threat: CP4 Fuel Pump and Fire Risk The CP4 fuel pump, a component used in certain engine configurations of the Silverado Sierra, has recently been linked in multiple eyewitness accounts and emerging investigations to overheating failures that can spark catastrophic engine fires. While GM has not yet issued a widespread recall or official safety bulletin, insiders and early test reports indicate the issue stems from a design or manufacturing flaw: inadequate heat shielding combined with pressure stressors in high-performance or heavy-duty applications.
