Nissan Armada intermittent starting issue with non-functional navigation and radio systems on Nissan Armada

Some Nissan Armada owners report experiencing intermittent starting issues alongside non-functional navigation and radio systems. These problems may stem from a weak or dead 12v battery, which can cause the engine to crank slowly or not at all. Additionally, ignition issues, such as a lack of spark, can prevent the engine from starting and may trigger misfire-related trouble codes like P0300 or P0301. Some owners have also encountered costly suggestions from dealers regarding OEM screen replacements for the navigation system. Furthermore, issues with the brake switch can disrupt the starting process, leading to unusual behavior after a jump start. To mitigate these concerns, it is recommended that owners test the 12v battery, check for ignition-related problems, explore alternative solutions for the navigation system, and investigate the brake switch's impact on vehicle operation.
