2nd gen, 2024+ · 2024–present
1.2 Turbo (3-cyl) · 137 hp
Known problems
- Good to know
Infotainment / camera display glitches
Symptoms: the infotainment or backup-camera screen going dark on start-up, or intermittent Bluetooth dropouts
What to do: Try a software update or a system restart first; keep the infotainment firmware current. These are early-owner reports on a brand-new model, so treat them cautiously.
- Good to know usually from 50,000 mi (80,000 km)
Intake-valve carbon build-up (direct injection)
Symptoms: over higher mileage, rough idle, hesitation or misfires as carbon accumulates on the intake valves
What to do: This engine is purely direct-injected, so fuel does not wash the intake valves; periodic walnut-blast or intake cleaning is a sensible long-term maintenance item. This generation is new, so long-term data is still limited.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the Oil Life monitor; halve for short-trip or severe use |
| Cabin air filter | every 22,000 mi (35,000 km) | — |
| Engine air filter | every 37,000 mi (60,000 km) | — |
| Spark plugs | every 60,000 mi (97,000 km) | turbo 3-cylinder; inspect earlier if running rough |
| Brake fluid important | every 36 months | — |
| Timing chain (no scheduled replacement) | — | chain-driven; inspect for noise rather than on a fixed interval |
1st gen, 2013-2022 · 2013–2022
1.4 Turbo · 138 hp
Known problems
- Worth watching
Premature radiator failure
Symptoms: coolant leaking from the radiator, overheating or repeated top-ups
What to do: Check whether your car is covered by the radiator special-coverage extension and inspect the radiator if you are losing coolant with no obvious hose or housing leak.
- Worth watching usually from 25,000 mi (40,000 km)
Valve-cover / PCV oil leaks
Symptoms: oil weeping from the valve cover, oily residue, rough idle or a whistling from a ruptured PCV diaphragm
What to do: The integrated PCV in the valve cover is a known weak point; if the cover leaks or the PCV diaphragm splits, replace the cover with the updated part rather than just cleaning it.
- Worth watching usually from 31,000 mi (50,000 km)
Coolant leaks (housing and turbo lines)
Symptoms: gradual coolant loss, low-coolant warnings, a sweet smell or drips around the thermostat housing, water outlet or turbo coolant feed
What to do: Track the coolant level and pressure-test if it keeps dropping; common leak points are the plastic thermostat housing/water outlet and the turbo coolant-feed O-ring.
- Good to know
Cold-weather PCV / crankcase-vent icing
Symptoms: loss of power or reduced-power mode in hard frost, from ice blocking the crankcase-vent passage near the intake manifold
What to do: Mostly affects use in extreme cold; keep up with the PCV/valve-cover service and let the engine warm before heavy load in freezing weather.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the Oil Life monitor; halve for short-trip or cold-climate use |
| Cabin air filter | every 22,000 mi (35,000 km) | — |
| Engine air filter | every 37,000 mi (60,000 km) | — |
| Spark plugs | every 60,000 mi (97,000 km) | turbo engine — inspect earlier if running rough |
| Brake fluid important | every 36 months | — |
| Timing chain (no scheduled replacement) | — | chain-driven; inspect for noise rather than on a fixed interval |
Manufacturer-declared fuel economy
| Engine | City | Highway | Combined | Cycle |
|---|---|---|---|---|
| 1.2 Turbo (3-cyl) 2nd gen, 2024+ · 2024–present | 28 mpg (8.4 L/100 km) | 32 mpg (7.4 L/100 km) | 30 mpg (7.8 L/100 km) | EPA |
| 1.4 Turbo 1st gen, 2013-2022 · 2013–2022 | 24 mpg (9.8 L/100 km) | 31 mpg (7.6 L/100 km) | 27 mpg (8.7 L/100 km) | EPA |
Lab-cycle figures, each shown with the cycle it was measured under — the same car under WLTP, NEDC, EPA or JC08 can differ by up to 20%. Real-world consumption typically runs 15–30% above the declared number, and that gap is normal, not a fault.

Frequently asked
What are the most common Chevrolet Trax problems?
The faults reported most often are: Premature radiator failure; Valve-cover / PCV oil leaks; Coolant leaks (housing and turbo lines). Symptoms, the mileage each appears at and what to do about it are all above.
How often does the Chevrolet Trax need servicing?
Engine oil & filter change — every 7,000 mi (12,000 km) or 12 months. The full published schedule is above; your car's own service book always takes precedence.
What is the real fuel consumption of the Chevrolet Trax?
The manufacturer declares 30 mpg (7.8 L/100 km) combined for the 1.2 Turbo (3-cyl) under the EPA cycle. In real use expect 15–30% more — that gap is normal.
Where does this data come from?
Brimly's Vehicle Knowledge Base — the same verified facts the app's AI assistant answers from. Every fault is written up from public sources and then checked by a human before it is published; nothing here is generated on the fly.
