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 Encore GX is known for is Turbocharger failure (1.3T) from about 40,000 miles ($1,200-$2,200). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
1.2L turbo I3 pairs ONLY with CVT; AWD 1.3L turbo I3 uses the more reliable 9-speed auto - prefer the AWD/9-speed. Timing CHAIN. 2026 got a light refresh. dexos1 synthetic on oil-life monitor.
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 Encore GX retires around 95,000 miles - but the exit window opens earlier here: Turbocharger failure (1.3T) risk window ($1,200-$2,200) opens ~40,000 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.
