Toyota Highlander intermittent stalling after starting with no dashboard warning lights on Toyota Highlander

Some Toyota Highlander owners report experiencing intermittent stalling after starting, even when no dashboard warning lights are present. Common issues include fuel-related problems, such as bad gas or water in the gas tank, which can lead to rough engine performance and stalling. Additionally, owners may need to check and secure various connections, including battery terminal connections and visible grounds, to rule out potential causes. If the battery is functioning but there are no dashboard lights, the ignition switch might be malfunctioning, which can be tested by observing if the dash lights go out during starting attempts. Furthermore, some owners find that insufficient fuel in the tank or a flooded engine can prevent the vehicle from starting, suggesting that refueling or following proper starting procedures may be necessary to resolve these issues.
