15.5% of Mercedes-Benz GLCs that failed an MOT failed the next one too, against 11.5% after a pass (2019–2024, n = 5,690). The failure most likely to come back is ‘lamps, reflectors and electrical equipment’: 17.1% of those fails recurred at the next MOT.

What does a Mercedes-Benz GLC cost to run in a fleet?

Of every 100 Mercedes-Benz GLCs tested at age 5, about 11 failed the MOT first time; at age 9, about 18 (rough estimate). These are one-year rates for different cars tested in the same year, not a fleet followed over time; the steepest one-year step in this cross-section is between cars aged 5 and 6, 3.07 percentage points (2024).

Mercedes-Benz GLC MOT: quick answers

What is the Mercedes-Benz GLC first-time MOT pass rate?

87.1% of first attempts passed in 2024 (78,203 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.

Why does this number differ from other sites?

Other sites may count retests or all attempts. This page uses 78,203 primary tests: 12.94% failed first time and 88.8% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 75.6 is shown separately.
