Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Sierra 1500 Limited 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 | $560 | $16 |
| 5 years | 60,000 mi | $1,545 | $26 |
| 7 years | 84,000 mi | $1,985 | $24 |
| 10 years | 120,000 mi | $3,425 | $29 |
| 15 years | 180,000 mi | $5,605 | $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 Sierra 1500 Limited is known for is 5.3L (L83) AFM lifter failure & oil consumption from about 50,000 miles ($1,500-$3,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
'Sierra 1500 Limited' = previous-generation (K2XX) Sierra sold as a lower-cost line for 2019 ONLY, alongside the redesigned 2019 Sierra. Engines: 4.3L V6, 5.3L (L83) & 6.2L (L86) V8 with AFM; 6- or 8-speed auto; timing CHAIN. Towing/off-road = severe service (half intervals). Catch-can / AFM-delete mitigates lifter/oil-burn risk.
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 Sierra 1500 Limited retires around 95,000 miles - but the exit window opens earlier here: 5.3L (L83) AFM lifter failure & oil consumption risk window ($1,500-$3,500) opens ~50,000 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.
