Known repair windows
What Carnival 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 Carnival 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 | $120 | $10 |
| 3 years | 36,000 mi | $850 | $24 |
| 5 years | 60,000 mi | $1,915 | $32 |
| 7 years | 84,000 mi | $2,355 | $28 |
| 10 years | 120,000 mi | $4,385 | $37 |
| 15 years | 180,000 mi | $6,300 | $35 |
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 Carnival is known for is Fuel system leak (recall 2022-2026) ($0 (recall)). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Timing CHAIN on 3.5L Lambda III V6 GDI (287 hp), 8-speed auto, FWD. KA4 generation (2022+). Normal oil 7,500 mi / severe 3,750 mi. Check open fuel-system recall.
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 Carnival 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.
