Chevrolet Suburban 1500 knocking noise on startup, possible engine failure with oil consumption issue on Chevrolet Suburban 1500

Some Chevrolet Suburban 1500 owners report experiencing a knocking noise on startup, which raises concerns about possible engine failure and excessive oil consumption. These issues may stem from a faulty engine knock sensor that can cause unusual engine noises and decreased acceleration. Additionally, low oil levels are frequently cited as a cause of engine knocking. Ignition problems, issues with rod bearings, and bad spark plugs are also common contributors to this noise, affecting proper engine combustion. In some cases, the knocking may be linked to the oil filter rather than the oil pump. Owners facing these engine-related problems may find protection under California's lemon laws. To mitigate these concerns, it is advisable to check the engine knock sensor, maintain proper oil levels, inspect ignition components, and evaluate the condition of rod bearings and spark plugs. If the knocking persists, seeking professional diagnosis is recommended to prevent potential engine failure.
