2016 Lexus Lx
Vehicle Specs & Maintenance Data
The 2016 Lexus Lx maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Lexus Lx.
For oil changes, the 2016 Lexus Lx takes 0W-20 Full Synthetic motor oil with a capacity of 6.2 quarts. Brake fluid type is DOT 3, the recommended coolant is Pink Long Life Coolant (OAT), and transmission fluid is ATF WS. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Lexus Lx, torque the lug nuts to 97 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.
Owners of the 2016 Lexus Lx have reported 5 common issues including "Air Suspension (AHC) Accumulator and Height Sensor Failure", "Infotainment System Lag and Outdated Interface" and "Brake Actuator Grinding Noise".

Air Suspension (AHC) Accumulator and Height Sensor Failure
The Active Height Control (AHC) hydraulic suspension system on the LX 570 is prone to accumulator sphere failure and height sensor malfunction. Symptoms include the vehicle sagging on one corner, a suspension warning light, and the vehicle failing to raise or lower when commanded. The AHC system uses nitrogen-charged accumulators that lose pressure over time.
Diagnose the specific failed component using the Lexus diagnostic system. Replace the AHC accumulator spheres (they should be replaced as a set) and recalibrate the height sensors. The AHC pump relay and pump motor should also be inspected. Some owners convert to a conventional coil spring suspension to eliminate the AHC system entirely.
Est. Cost: $800 - $2,000 per accumulator; $500 - $1,000 per height sensor; $3,000 - $5,000 for coil conversionInfotainment System Lag and Outdated Interface
The 2020 LX 570's 12.3-inch split-screen infotainment system controlled by the Remote Touch trackpad suffers from slow response times, frequent hesitation when scrolling through menus, and an overall dated user interface. Apple CarPlay was added but Android Auto is not available. The navigation system's map rendering is noticeably slow.
Update the Lexus Enform multimedia system to the latest software version for improved responsiveness. Use Apple CarPlay via USB for modern navigation and media apps. Adjusting the Remote Touch trackpad sensitivity to the lowest setting can improve accuracy. Some owners install aftermarket Android Auto adapters for wireless connectivity.
Est. Cost: $0 for software update; $100 - $300 for aftermarket Android Auto adapterBrake Actuator Grinding Noise
The electronically controlled brake actuator on the LX 570 can produce a noticeable grinding or whirring noise during low-speed braking and when the vehicle comes to a stop. The noise is caused by the actuator motor cycling to maintain brake pressure and is particularly audible in the cabin due to the vehicle's otherwise quiet operation.
Lexus issued a TSB for brake actuator noise, recommending a software update to the brake actuator control ECU. The update reduces the frequency of actuator cycling at low speeds. If the noise is excessive after the software update, the brake actuator unit may need replacement. The regenerative-style braking system is inherently noisier than conventional brakes.
Est. Cost: $0 for software update under warranty; $2,000 - $4,000 for actuator replacementSecondary Air Injection System Failure
The secondary air injection (AI) system, which pumps air into the exhaust manifold during cold starts to reduce emissions, can fail due to air pump motor burnout or clogged air switching valves. The check engine light illuminates with codes P2440, P2441, P2442, or P2443. This is a well-known issue on the 3UR-FE 5.7L V8 engine.
Replace the secondary air injection pump and air switching valve assemblies. The intake ports on the exhaust manifold should be cleaned of carbon deposits. Toyota/Lexus issued a TSB for this system on the 3UR-FE engine. Both pumps and valves (driver and passenger side) should be replaced simultaneously.
Est. Cost: $800 - $2,000 for both air pump and valve assembliesFuel Economy Below Expectations
The LX 570's 5.7L V8 with a 6-speed automatic delivers real-world fuel economy of 11-14 MPG in mixed driving, which is below the EPA estimate of 13 city/18 highway. Owners who tow or drive in urban environments frequently see single-digit fuel economy. The vehicle's 3-ton curb weight and aerodynamic profile are primary factors.
Ensure the engine is properly maintained with clean air filters and fresh spark plugs. Verify tire pressures are at the recommended 33 PSI, as underinflation significantly impacts fuel economy. Use the ECO drive mode when available. A catch-can installation can help maintain engine efficiency by reducing carbon buildup. There is no hardware modification to significantly improve the LX 570's fuel consumption.
Est. Cost: $0 for maintenance and driving habits; inherent to vehicle design
