3.5L V35A-FTS Twin-Turbo V6 - RWD
Petrol
Listen carefully for any subtle wastegate rattle or metallic tapping during low-load acceleration, as the twin-turbo system on the V35A-FTS is complex and worthy of a thorough listen.
Cycle through every setting on the air suspension by switching drive modes; ensure the vehicle rises and levels evenly without dashboard warnings, as air struts are a common point of age-related wear.
Operate the infotainment controller and all touch surfaces extensively, as the Lexus multimedia interfaces of this generation can occasionally develop unresponsive zones over time.
Perform a cold start and monitor the idle; ensure it settles smoothly, as the high-pressure fuel injection system requires clean, consistent maintenance to operate at its peak.
Recommended transmission fluid service and inspection of the complex multi-link suspension bushings.
Typically the time to verify the cooling system health and inspect turbocharger plumbing for any signs of heat-induced degradation.
Deep service interval for spark plugs and a comprehensive scan of all electronic control modules for any latent fault codes.
Prioritize oil changes every 10,000km using premium synthetic oil to keep those twin turbos running happily.
Regularly check the condition of the run-flat tires, as they are essential for the intended ride comfort of the LS.
Keep the vehicle's battery voltage topped up, as the sophisticated electronics in the LS are quite sensitive to low power.
Periodically clear out the sunroof and door drains to prevent moisture ingress, which keeps the interior electronics dry and happy.
Ensure the brake fluid is flushed every two years to maintain the crisp pedal feel expected of a flagship sedan.
Estimated repair costs if issues arise
If this component needs attention in the future, it is wise to note that replacing individual air struts is a specialized task. Depending on the car's history, you might eventually need to budget for the pump or the struts themselves to ensure the ride remains silky smooth.
Given the V35A-FTS engine's performance, if this component needs attention in the future, it involves accessing the turbos which are nestled deep in the engine bay. It is a labor-intensive job that is best handled by technicians familiar with Lexus turbo systems.
The LS is a heavy, luxurious vehicle, and the brakes work hard. Depending on the car's history, you might eventually need to budget for a full set of high-performance rotors and pads to maintain that reassuring stopping power.
