Known repair windows
What Express 2500 owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.

Operator notes
2500 is the 3/4-ton Express, frequently ordered with the 6.6L L8T gas V8. Same durable GMT610 platform, timing CHAIN, and 8L90 8-speed as the base Express, but the heavier GVWR means more frequent brake service and severe-schedule fluids under load. Diesel option discontinued; gas only for 2025.
When the smart money sells
On fleet math, a gas Express 2500 retires around 95,000 miles. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
