The Lexus LS 460, the fourth generation of Lexus's flagship sedan, promised a blend of luxury, performance, and, most importantly, reliability. But does it live up to the legendary Lexus reputation for bulletproof construction? Let's dive deep into the build quality and reliability aspects of the LS 460 to see if it's a dependable choice for your next luxury car.
Lexus's Reputation: A Hard Act to Follow
Lexus built its brand on the back of exceptional reliability. The original LS 400 shocked the automotive world with its smooth engine, quiet ride, and, crucially, its almost unheard-of dependability. This set a high bar for subsequent models, including the LS 460. So, the question isn't just "Is the LS 460 reliable?", but "Is it Lexus reliable?"
The LS 460: A Closer Look at its Construction
The LS 460, produced from 2006 to 2017, represents a significant leap forward in technology and features compared to its predecessors. This includes a new 4.6-liter V8 engine, an eight-speed automatic transmission (a first for Lexus), and a host of advanced safety and convenience systems. But more features mean more potential points of failure. Let’s examine the core components:
- Engine: The 1UR-FSE 4.6-liter V8 is generally considered robust. It's known for its smooth power delivery and relatively quiet operation. However, carbon buildup on the intake valves, particularly in earlier model years, can be an issue. This can lead to rough idling and reduced performance. Regular cleaning or preventative measures like using a fuel system cleaner can help mitigate this.
- Transmission: The A760E/A760H eight-speed automatic transmission is complex, but overall, fairly reliable. However, it's crucial to ensure it's properly maintained with regular fluid changes using the correct Lexus/Toyota WS fluid. Neglecting transmission maintenance can lead to rough shifting and, eventually, failure.
- Suspension: The LS 460 offered both traditional coil spring suspension and an optional air suspension system. The air suspension, while providing a supremely comfortable ride, is a common source of problems. Air struts can leak, compressors can fail, and sensors can malfunction, leading to expensive repairs. Coil spring suspensions are generally more durable and less problematic.
- Electronics: The LS 460 is packed with electronics, including navigation, infotainment, climate control, and safety systems. While most of these systems are reliable, some owners have reported issues with the navigation system, particularly with the screen and software. The Mark Levinson audio system, a popular option, is generally reliable, but amplifier failures can occur.
- Body and Interior: The build quality of the LS 460's body and interior is generally excellent. The paint is durable, and the interior materials are high-quality. However, sun damage can affect the leather upholstery and dashboard over time. Some owners have also reported issues with the power door closers, particularly in older models.
Common LS 460 Problems: What to Watch Out For
While the LS 460 is generally considered reliable, certain issues are more common than others. Knowing these potential problems can help you make an informed decision when purchasing one, and allow you to proactively address them.
- Air Suspension Issues: As mentioned earlier, air suspension problems are a significant concern. Replacing air struts and compressors can be expensive. Consider a model with the standard coil spring suspension for greater peace of mind.
- Carbon Buildup: Carbon buildup on the intake valves can cause rough idling and reduced performance. Regular cleaning or preventative measures are recommended.
- Water Pump Leaks: Water pump failures are not uncommon as the car ages. Keep an eye out for coolant leaks and overheating.
- Control Arm Bushings: The control arm bushings, particularly in the front suspension, can wear out over time, leading to clunking noises and handling issues.
- Dashboard Cracking: In warmer climates, the dashboard can be prone to cracking due to sun exposure.
- Battery Drain: Some owners have reported issues with battery drain, which can be caused by a variety of factors, including a faulty alternator, a parasitic draw, or a failing battery.
- Navigation System Issues: The navigation system screen can fail or become unresponsive. Software updates may resolve some issues, but replacement may be necessary in some cases.
Model Year Variations: Are Some Years Better Than Others?
While the LS 460 remained largely unchanged throughout its production run, there are some minor differences between model years that can affect reliability.
- 2007-2009 Models: These early models are more prone to carbon buildup issues.
- 2010-2012 Models: These models received a minor facelift and some improvements to the infotainment system.
- 2013-2017 Models: These models received a more significant facelift, including a new spindle grille and updated interior. They also benefited from some improvements to the drivetrain and suspension.
Generally, the later model years (2013-2017) are considered to be slightly more reliable due to the refinements and improvements made over the earlier years. However, all model years can be reliable with proper maintenance.
Maintenance is Key: Keeping Your LS 460 Running Smoothly
Like any car, the LS 460 requires regular maintenance to ensure its reliability. Following the manufacturer's recommended maintenance schedule is crucial. Here are some key maintenance items:
- Oil Changes: Regular oil changes with the correct type of oil are essential for engine longevity.
- Transmission Fluid Changes: As mentioned earlier, regular transmission fluid changes are crucial for the health of the eight-speed automatic transmission. Use only Lexus/Toyota WS fluid.
- Coolant Flushes: Regular coolant flushes help prevent corrosion and overheating.
- Brake Fluid Flushes: Brake fluid absorbs moisture over time, which can lead to corrosion and reduced braking performance. Regular brake fluid flushes are recommended.
- Spark Plug Replacement: Spark plugs should be replaced according to the manufacturer's recommended interval.
- Air Filter Replacement: A clean air filter ensures proper engine performance and fuel economy.
- Inspection of Suspension Components: Regularly inspect the suspension components, including the air struts (if equipped), control arm bushings, and ball joints, for wear and tear.
- Battery Maintenance: Keep the battery terminals clean and corrosion-free. Consider using a battery tender if the car is not driven regularly.
Comparing the LS 460 to its Rivals
How does the LS 460 stack up against its competitors in terms of reliability? The LS 460 generally fares well compared to other luxury sedans in its class, such as the BMW 7 Series, Mercedes-Benz S-Class, and Audi A8. While those European rivals offer more advanced technology and features, they often come with higher maintenance costs and a greater risk of breakdowns. The LS 460's simpler design and Toyota-derived components contribute to its greater reliability. However, it's important to note that even the LS 460 is not immune to problems, and regular maintenance is crucial.
The Used LS 460 Market: What to Look For
If you're considering buying a used LS 460, there are a few things to keep in mind:
- Maintenance Records: Look for a car with complete and well-documented maintenance records. This is the best way to gauge how well the car has been cared for.
- Pre-Purchase Inspection: Have a trusted mechanic perform a pre-purchase inspection to identify any potential problems.
- Air Suspension Check: If the car is equipped with air suspension, carefully inspect the air struts and compressor for leaks or signs of wear.
- Carbon Buildup Check: Ask the mechanic to check for carbon buildup on the intake valves.
- Test Drive: Take the car for a thorough test drive to check for any unusual noises, vibrations, or handling issues.
- Check for Recalls: Check the vehicle identification number (VIN) for any outstanding recalls.
Is the LS 460 a Good Value?
Despite potential issues, the LS 460 remains a compelling value proposition in the used luxury car market. It offers a luxurious and comfortable ride, a powerful engine, and a host of features at a fraction of the cost of a new luxury sedan. With proper maintenance, an LS 460 can provide years of reliable service.
