What to check when shopping a used 2018 IS

Before buying, inspect the car’s history, current condition, and whether any important updates were completed. The following points help buyers assess reliability and avoid surprises.

Checklist for a thorough inspection

• Service history: confirm regular maintenance (oil changes, brake service, and other routine items) and note any major repairs.


• Transmission behavior: ensure smooth shifts in IS 300/IS 350; listen for hesitations, surges, or unusual noises during gear changes.


• Infotainment and electronics: verify touchscreen usability, Bluetooth connectivity, navigation, and sound system; check for software updates.


• Safety and recalls: confirm all open recalls are completed and check the VIN for any safety notices.


• Visual and mechanical condition: inspect tires, brakes, suspension components for wear; look for leaks, rust, or frame damage.

Completing a thorough pre-purchase inspection helps you avoid common reliability pitfalls and can lead to a well-maintained example.

Ownership costs and long-term reliability considerations

Beyond the purchase price, prospective owners should weigh maintenance, parts, fuel, and insurance costs that affect long-term reliability and ownership satisfaction.

What affects ongoing costs

• Maintenance and repairs: while Lexus reliability is strong, age-related wear (brakes, tires, suspension bushings) can increase costs for older models.


• Parts and service: luxury-brand parts and specialized service can be pricier than non-luxury brands; using independent shops with Toyota-based parts can help manage costs.


• Fuel economy: engine choice (IS 300 vs. IS 350) influences real-world efficiency, which in turn affects running costs.


• Insurance: premiums for a luxury sedan are typically higher than for mainstream compact cars, depending on driver profile and location.

Sticking to regular maintenance and choosing a well-documented vehicle can help keep ownership costs predictable and reliability high over time.

Bottom-line verdict

Overall, the 2018 Lexus IS generally ranks as a reliable option in the luxury compact segment, backed by Lexus’ reputation for durability. The main caveats are electronics-related nuisances that can affect everyday usability, and the typical higher maintenance costs that accompany aging luxury cars. For the best reliability, prioritize a vehicle with complete service records and have a trusted mechanic perform a pre-purchase inspection.

Summary

Key takeaways: The 2018 Lexus IS tends to be reliable within its class, reflecting Lexus/Toyota durability. Watch for electronics issues and ensure all recalls are addressed. Maintenance and repair costs for an older luxury sedan can be higher than non-luxury rivals, but a well-documented, well-maintained example can offer long-term satisfaction and dependable performance.
