Known issues on the 2020 Armada. Two recalls are on federal record for this model year. The first covers the fuel pump control/drive module: the impeller inside the fuel pump can swell and bind, causing the pump to fail and the engine to stall, increasing the risk of a crash. The second covers the certification labels on vehicles equipped with 22-inch wheels, where an incorrect Gross Axle Weight Rating can allow the vehicle to be overloaded, increasing the risk of a crash. Owners have filed 10 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you're diagnosing a fuel pump fault or confirming axle load ratings, it keeps you on the OEM procedure and the correct specification for your specific 2020 Armada.
