The 2017 Lexus IS is a genuinely reliable proposition, with a 92.1% first-time MOT pass rate that sits well above the UK average of 80%. However, one concern is that 21.5% of vehicles in this cohort have recorded a dangerous defect at some point, which is notably above the typical threshold and worth investigating on any used example you're considering.
These cars are running at sensible mileage for their age (median 43,258 miles), and when they do fail MOT, it's usually minor—averaging 0.61 failures per vehicle. With 4.4 advisories per car on average, you're looking at routine maintenance items rather than structural problems, so budget for preventive work but don't expect expensive surprises. Before purchase, get a full service history check and specifically ask the seller about any previous dangerous defect recordings.
The 2017 Lexus Is passes its MOT first time at roughly the UK average rate (92.1%) — solid but worth checking this vehicle's history carefully.
These stats describe 1,624 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.
