Known repair windows
What Blazer EV 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
EV: no oil, spark plugs, or transmission fluid. Regen braking makes friction pads last 100k+ mi (but low use can seize calipers). Battery/inverter coolant loops are long-interval. No Apple CarPlay/Android Auto. Ultium platform.
When the smart money sells
On fleet math, a battery-electric Blazer EV retires around 150,000 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.
