The 2017 Trax uses GM's 1.4L turbo Ecotec paired with a 6-speed automatic—a platform shared with the Sonic and Cruze that's notorious for catastrophic engine failures and transmission cooling issues. When these fail, repair costs often exceed the vehicle's value.
Symptoms: Sudden loss of power and metal-on-metal knocking sound, Oil consumption increasing to 1 quart per 500-1000 miles, Check engine light with misfire codes, Coolant mixing with oil (milky dipstick), Catastrophic failure often occurs without warning after oil consumption phase
Fix: This engine has a fatal design flaw where the piston rings fail, leading to oil consumption, carbon buildup, and eventually spun bearings or cracked pistons. Once knocking starts, it's too late—needs complete engine replacement or rebuild. Short block replacement takes 18-22 hours labor. Most shops recommend used/reman engine swap over rebuild due to core design issues.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Line Leaks
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Transmission fluid puddles under vehicle (red fluid), Slipping between gears or delayed engagement, Transmission overheating warnings, Low transmission fluid level on dipstick, Lines corrode where they connect to radiator
Fix: The steel cooler lines rust through at the crimp joints and radiator connections—a known GM issue across this platform. Requires replacement of both lines and often the external cooler. If driven low on fluid, transmission damage occurs quickly. 3-4 hours labor for lines only, but often discover internal transmission damage requiring rebuild.
Symptoms: Severe clunking when shifting from Park to Drive/Reverse, Vibration through cabin at idle, Visible engine/transmission movement when accelerating, Rough engagement into gear
Fix: The hydraulic transmission mount collapses internally, allowing excessive drivetrain movement. This is a wear item on this platform but fails prematurely. Replacement is straightforward but requires supporting the engine/transmission. 2-3 hours labor.
Estimated cost: $350-550
Turbocharger Wastegate Rattle and Failure
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Rattling noise on cold start that disappears when warm, Loss of boost/power on acceleration, Check engine light with boost control codes (P0299, P0234), Turbo whistle or hissing sounds
Fix: The wastegate actuator arm wears and rattles, eventually sticking or failing completely. Early stages just rattle; later stages cause overboosting or underperformance. Turbo replacement required—no rebuild option that's cost-effective. 6-8 hours labor due to tight engine bay access.
Estimated cost: $1,400-2,200
Coolant Thermostat Housing Leak
Occasional · medium severity
Typical onset: 60,000-110,000 mi
Symptoms: Coolant smell in cabin or under hood, Small coolant puddles under front of vehicle, Overheating or running too cool, Visible coolant residue on engine block, Low coolant warning light
Fix: The plastic thermostat housing cracks at the seams or warps, causing external coolant leaks. Must replace entire housing assembly with updated metal version (if available) or OEM plastic. 2-3 hours labor, but access requires removing intake components.
Estimated cost: $400-650
Front Lower Ball Joint Separation (Recall-Related)
Occasional · high severity
Symptoms: Clunking over bumps in front end, Wandering steering or pulling, In worst cases: sudden loss of steering control and wheel collapse, Uneven tire wear on inside edge
Fix: NHTSA recall 18V-669 and 19V-120 cover ball joint separation risk due to manufacturing defect. Even post-recall, these joints wear prematurely. If vehicle wasn't serviced under recall, check immediately. Replacement requires pressing out old joint or replacing entire control arm. 2-3 hours per side.
Estimated cost: $0 (if recall applies), $300-500 per side (if not covered)
PCV System Failure Causing Oil Leaks and Consumption
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Oil residue around valve cover and intake, Rough idle or hesitation, Excessive oil consumption (1 quart per 1500-2000 miles), Check engine light with lean codes, Hissing sound from engine bay
Fix: The PCV valve and intake manifold have integrated passages that clog with carbon, causing crankcase pressure buildup. This forces oil past seals and contributes to the piston ring carbon issues. Requires intake manifold cleaning or replacement and new PCV components. 3-4 hours labor.
Estimated cost: $450-750
Owner tips
Check oil level every 500 miles religiously—the 1.4T consumes oil by design, and running low accelerates catastrophic failure
Inspect transmission cooler lines annually for rust—catching leaks early prevents $3000+ transmission replacement
Use only Dexos-approved full synthetic oil and change every 5000 miles maximum to fight carbon buildup
Verify recall 18V-669 (ball joints) was completed—potentially life-threatening if not addressed
Budget $1000/year for unexpected repairs after 60k miles—this platform has reliability issues that compound
Avoid unless under $6000 with documented engine replacement—the 1.4T Ecotec is a ticking time bomb that makes this otherwise practical crossover a poor used-car value.

General Motors LLC (GM) is recalling certain 2015-2018 Chevrolet Trax vehicles. A joint in one or both of the front lower control arms may have been improperly welded. An improperly welded joint may break, resulting in the partial separation of the lower control arm from the vehicle.
Consequence: A partial separation of the lower-control arm from the vehicle could cause the attached front wheel to toe outward, impacting the vehicle's handling and steering and increasing the risk of crash.
Remedy: GM will notify owners, and dealers will inspect the left and right front lower-control arms, replacing them as necessary, free of charge. The recall began November 6, 2019. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is A192261870.

General Motors LLC (GM) is recalling certain model year 2015-2017 Chevrolet Silverado 2500 HD, 3500 HD, Tahoe, Suburban, GMC Sierra 2500 HD and 3500 HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade and Cadillac Escalade ESV vehicles and 2014-2017 Chevrolet Corvette, Silverado 1500, Trax, Caprice Police Pursuit Vehicle, GMC Sierra 1500, Buick Encore, and 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles. In the affected vehicles, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on October 13, 2016. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 16007.
