Moderate sample. 373 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
The 2019 Mercedes-Benz GLS is significantly more reliable than the UK average, with a first-time MOT pass rate of 91.5% against the national benchmark of 80%. However, nearly 20% of these vehicles have recorded a dangerous defect at some point, which is worth investigating on any specific example you're considering—ask the seller for full MOT history and check for patterns in what failed.
These GLSes are running at modest mileage for their age (median 38,313 miles), which partly explains the strong pass rate, though the 0.46 average failures per vehicle suggests few serious issues when they do crop up. The 2.9 advisories per test indicate minor wear and maintenance needs are normal, so budget for routine servicing; before purchase, get a pre-buy inspection focused on suspension and brake components, where Mercedes SUVs commonly show early wear.
The 2019 Mercedes Benz Gls passes its MOT first time at roughly the UK average rate (91.5%) — solid but worth checking this vehicle's history carefully.
These stats describe 373 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.
