According to Au7o's analysis of 180+ owner reports, the 2017 Chevrolet Trax has 5 documented known issues. No issues are rated critical, indicating generally reliable ownership. The most commonly reported issue is Coolant Leak from Water Outlet Housing with 180 owner reports. Across all issues, repair costs range from $50 to $2,800. DIY maintenance guides at au7o.io.
On the 2015-2022 Chevrolet Trax 1.4T Ecotec, the Trax uses the same 1.4T Ecotec engine as the Cruze with similar issues: turbo oil feed line leaks, PCV system failures, and coolant system plastic component cracking. The coolant outlet/thermostat housing is the most common failure point.
Same fixes as Cruze 1.4T - replace water outlet, inspect turbo oil lines, replace valve cover for PCV issues.

On the 2015-2022 Chevrolet Trax 1.4L Turbo, the 1.4L turbocharged engine burns oil at an excessive rate, often consuming a quart every 1,000-2,000 miles. The issue is attributed to piston ring design and PCV system routing. GM considers up to 1 quart per 2,000 miles "normal" but many owners find this unacceptable.
Monitor oil level between changes and top off as needed. Replace the PCV valve and inspect the intake manifold for oil buildup. For severe consumption, an engine teardown to replace piston rings and valve stem seals may be necessary. Use full synthetic 5W-30 oil as specified.

On the 2014-2020 Chevrolet Trax 1.4L Turbo, the 1.4L turbocharged engine in the Trax (shared with Cruze, Sonic, and Buick Encore) develops wastegate actuator failures. The wastegate seal degrades, allowing exhaust gases to bypass the turbine wheel and reduce boost. The wastegate actuator arm design has a known mechanical weakness. GM TechLink bulletin noted many returned turbochargers had no fault and emphasized proper diagnosis before replacement.
Confirm the fault before replacing parts by scanning for P0299, logging commanded vs. actual boost, and inspecting the turbo wastegate lever/actuator for excessive play, sticking, or a loose flapper; also smoke-test the intake/charge-air system and check the bypass valve, PCV system, and vacuum/pressure control plumbing so a boost leak is not mistaken for turbo failure. If the wastegate arm or flapper is worn, GM typically services this as a complete turbocharger assembly rather than the actuator alone; replace the turbo assembly with new gaskets, oil feed/return seals, and related hardware, then clear codes and verify boost on a road test. Typical repair cost is about $1,200-$2,000 at an independent shop or $1,800-$2,800 at a dealer depending on labor rates and whether the catalytic converter fasteners/oil lines also need replacement.

On the 2015-2022 Chevrolet Trax 1.4L Turbo, the plastic water outlet housing on the 1.4L turbo engine is prone to cracking and leaking coolant. The housing sits on the back of the engine block and deteriorates from heat cycling. Coolant loss can lead to overheating if not addressed.
Replace the plastic water outlet housing with an updated design. Many owners opt for aftermarket aluminum replacements for improved durability.

On the 2015-2022 Chevrolet Trax, the 6T40 automatic transmission exhibits rough or harsh shifts, delayed engagement from Park or Reverse, and occasional lurching. The valve body is the primary culprit, with wear on the pressure regulator bore causing erratic shift quality. Cold weather operation tends to make the issue more pronounced.
A transmission fluid and filter change using Dexron HP fluid is the first step. If symptoms persist, a valve body replacement or rebuild addresses the root cause. Have the TCM reflashed to the latest GM calibration. In severe cases, a remanufactured transmission may be the most cost-effective solution.
