Mercedes-benz Glc 220 D 4MATIC AMG Line Auto Reliability, MOT Pass Rate & Common Faults

The Mercedes-benz Glc 220 D 4MATIC AMG Line Auto has an overall MOT pass rate of 94.7% across 1,326 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.

The most common problems on the Mercedes-benz Glc 220 D 4MATIC AMG Line Auto are windscreen wiper blade deteriorated (1 recorded failures), brake pedal anti-slip provision worn smooth (1), and headlamp aim too high (hotspot upper edge above the horizontal 0% line) (1). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.

On the safety side, the most frequently flagged dangerous fault is brake pad(s) less than 1.5 mm thick. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Mercedes-benz Glc 220 D 4MATIC AMG Line Auto with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.

A typical Mercedes-benz Glc 220 D 4MATIC AMG Line Auto owner drives around 9,935 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.

Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
