Best Model Years
2018-2020 (post-refresh, pre-new generation)
Years to Avoid
None stand out as particularly problematic for this generation, but the 2014-2016 models had some minor early electrical TSBs that were largely resolved by 2017.
Biggest Strengths
- Naturally aspirated V6 engine (IS 300 AWD / IS 350) reliability
- Robust automatic transmissions
- Superior interior fit and finish longevity
Top Risk Areas
The systems that tend to fail first on the 2020 Lexus IS, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The Remote Touch controller, while functional, can be frustratingly imprecise, leading to distraction. Software can occasionally lag or require a reset, though hardware failures are rare.
While not a widespread issue, some owners of the 2.0L turbo (IS 300 RWD) have reported ignition coil failures or premature spark plug wear, leading to misfires. The V6 engines are less prone.
The V6 engines, while robust, can eventually develop leaks from the water pump assembly as the plastic components or seals degrade. This is more of a wear item than a design flaw.

Elevated Risk Zone
Beyond the initial warranty, you'll need to pay closer attention to wear items. The V6 water pump might start showing signs of wear, and suspension components like shocks/struts will be nearing the end of their optimal life. Minor electr…
High Risk Zone
While the Lexus IS is built to last well beyond this, expect more frequent attention to age-related wear. Drive belts, hoses, and major suspension components will likely require replacement. Regular detailed inspections become crucial to…
