Certain Chevrolet Colorado and GMC Canyon vehicles equipped with the 3.6L LGZ engine may experience a loss of engine oil caused by high oil pump pressure in cold weather start conditions. High oil pump pressures under these conditions may cause various components to fail, including the engine oil cooler (EOC), EOC lines, or the oil pump itself, resulting in a loss of lubrication in the engine. If this condition occurs, the Driver Information Center will display an oil can light and multiple warning messages (Oil Pressure Low, Turn Vehicle Off, or Engine Power is Reduced), depending on the state of the engine. If the vehicle continues to be driven with low oil despite the appearance of these warnings, the vehicle?s engine may seize, resulting in a stall or loss of propulsion. Only applies to vehicles in Canada or currently registered or previously registered in the state of Alaska. Dealers will replace the oil pump.
