What Avenger owners actually run into

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Avenger 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 | $75 | $6 |
| 3 years | 36,000 mi | $525 | $15 |
| 5 years | 60,000 mi | $1,425 | $24 |
| 7 years | 84,000 mi | $1,650 | $20 |
| 10 years | 120,000 mi | $3,300 | $28 |
| 15 years | 180,000 mi | $4,725 | $26 |
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 Avenger is known for is TIPM (Totally Integrated Power Module) failure from about 60,000 miles ($400-$900). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Final year 2014. Timing CHAIN on both 2.4L Tigershark and 3.6L Pentastar V6 (no belt). Uses Mopar oil-life system; severe service (short trips, heat) ~4,000-5,000 mi. Age now the dominant factor: rubber hoses, fuel lines, motor mounts.
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 gas Avenger retires around 95,000 miles - but the exit window opens earlier here: TIPM (Totally Integrated Power Module) failure risk window ($400-$900) opens ~60,000 mi. 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.
