Lexus GX460 cruise control malfunction with trac off and check engine lights on on Lexus GX460

Some Lexus GX460 owners report experiencing issues with cruise control, indicated by the illumination of the trac off and check engine lights. These warning lights may signal problems detected by the onboard computer related to engine driveability, transmission control, or the emissions system. Common causes for these alerts include broken MAF sensors, loose gas caps, faulty oxygen sensors, spark plugs, and catalytic converters. The trac off light specifically indicates that the traction control system has been deactivated, either manually or due to a malfunction. Resolving the check engine light is crucial, as it may help restore functionality to the trac system. Additionally, some owners notice symptoms of transmission failure, such as vibration at higher speeds and failure to shift into higher gears, which can be linked to diagnostic trouble codes like P2714. It is advisable for owners to address the underlying causes of the check engine light to potentially resolve the cruise control and trac off light issues, and if problems persist, seeking expert assistance for diagnosis and repair is recommended.
