Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Blazer EV at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $65 | $5 |
| 3 years | 36,000 mi | $355 | $10 |
| 5 years | 60,000 mi | $925 | $15 |
| 7 years | 84,000 mi | $2,215 | $26 |
| 10 years | 120,000 mi | $2,945 | $25 |
| 15 years | 180,000 mi | $5,505 | $31 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this Blazer EV is known for is HV Ultium battery degradation / replacement ($10,000-$20,000 out of warranty). It is a range, not a certainty - but it is the number to have in your head at the dealership.
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
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, 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.
