Lexus GX460 engine check light, traction control light on, and 4 Lo light blinking without engagement on Lexus GX460

Some Lexus GX460 owners report experiencing simultaneous illumination of the engine check light, traction control light, and 4LO light without engaging 4LO mode, which may indicate underlying issues with the vehicle's systems. These warning lights could signal problems related to emissions system components, sensors, or the catalytic converter. In particular, a misfire detected in a specific cylinder, such as Cylinder 4, has been known to trigger the check engine light and related symptoms. Additionally, issues with the traction control system may be indicated by the Trac Off light, and some owners have reported that solenoid faults, such as codes P0761 and P2714, could be responsible for the warning lights. To effectively address these concerns, it is recommended that owners have their vehicle inspected by a qualified mechanic to diagnose the specific causes and promptly resolve any detected misfires or solenoid faults to prevent further damage. If the issue persists after addressing potential causes, seeking professional assistance from a certified mechanic or dealership is advisable for optimal vehicle performance.
