In the European service world, Mercedes-Benz engine failures land on our lifts with regularity. 1,266 complaints across 92 year-model entries (2005–2023) is consistent with what we move in parts orders. The pattern repeats across model years, which usually points to a shared component supplier rather than a single bad production batch. 35 fire reports on the federal record — not common in this category but documented and worth weight. Across the 372 complaints reporting odometer mileage, the median failure lands at about 68,256 miles. Independent-shop repair on this category runs around $3,100; dealer pricing tends to run thirty to forty percent higher on European brands. Budget for a real pre-purchase inspection — compression and leakdown test, not just a code scan. Both are cheap and tell you what is left in the engine.
