The 2015 Lexus IS is significantly more reliable than the UK average, with a 90.3% first-time pass rate versus 80%, though nearly 28% of these vehicles have recorded a dangerous defect at some point—a concern worth investigating during a pre-purchase inspection. Both the hybrid and petrol variants perform similarly well, with pass rates around 90%, so fuel type isn't a reliability differentiator here.

These cars are running at a sensible 55,000–62,000 miles for their age, and while they average less than one failure per test, the high advisory rate of 5.7 per vehicle suggests wear-and-tear items need regular attention. Check the MOT history carefully for patterns in those advisories, and budget for preventative maintenance on common wear items rather than expecting major structural problems.

The 2015 Lexus Is has a decent first-time pass rate (90.3%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
Good baseline reliability. A 90.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 5.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 3,090 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
