Chevrolet Trax Best & Worst Years:
The Complete Ownership Encyclopedia (2014–2025)
What is the Chevrolet Trax? A subcompact crossover introduced by Chevrolet for 2013 globally (2015 in US). Built on the Gamma II platform, the Trax offers nimble handling and low entry price. However, Chevrolet Trax reliability varies dramatically by model year. This 360° guide reveals the best and worst years for Chevrolet Trax, why some engines fail early, and how to pick a bulletproof used model.
Why is model year crucial? The 1.4L Ecotec turbo (LUJ/LUV) went through 3 major revisions. Early versions (2014-2017) had flawed PCV systems, cooling system brittleness, and transmission programming issues. After 2018, GM applied over 20 engineering fixes. This guide merges NHTSA data, TSB logs, and owner surveys.
📅 Generations & Types of Chevrolet Trax
Knowing the differences helps target best value years:
- Gen 1.0 (2014–2017): High-risk 1.4L turbo, vulnerable PCV, water pump failures, plastic thermostat housing. Avoid unless budget under $6000 and ready for repairs.
- Gen 1.5 (2018–2019): Updated engine calibration, revised PCV baffle, improved turbo oil feed. Much safer. Considered ‘good’ years.
- Gen 1.5+ (2020–2022): Best of 1st generation. New water pump design, upgraded radiator fan, transmission refinement, better infotainment (Android Auto/Apple CarPlay). Peak reliability.
- Gen 2 (2024+): All-new 1.2L turbo three-cylinder, CVT, new chassis. Too early for long-term data, but initial reviews positive.
🏆 Best Chevrolet Trax Years (Full Details)
Least complaints per 1000 vehicles. Power train refined – rare coolant loss or PCV failures. Transmission shift logic optimized for smoother daily driving. Premier trim includes leather, heated seats, and optional AEB.
2020: First year of mechanical cooling system overhaul – new water pump part# 25194367 reduces leak failure by 65%. 2022: Final year of first-gen, most mature platform; less than 0.9% engine-related complaints on CarComplaints.
If budget is tight, 2018-2019 offer decent dependability after GM updated piston rings and PCV baffle. Still monitor for minor coolant residue. Average used price: $9k–$13k vs $17k for 2021.
🚫 Worst Chevrolet Trax Years – Stay Away
High failure rate: NHTSA logged 130+ engine complaints for 2014 alone. PCV valve failures cause rear main seal oil leaks (repair $1,800+). Many suffer from cracked turbocharger wastegate actuators. Transmission failures by 70k miles are common.
Though slightly improved, 2016 still has thermostat housing failure (often leaves driver stranded). 2017 models show premature timing chain stretch and oil consumption >1 quart per 1000 miles. Avoid high-mileage examples without proof of water pump replacement.
🔍 Definition of Problems: Why Trax Fails (Technical Deep Dive)
The 1.4L Ecotec engine (LUJ/LUV) uses an integrated PCV system inside the valve cover. When the PCV orifice clogs, crankcase pressure skyrockets, blowing out the rear main seal – a $1500-$2000 fix. Moreover, the plastic water outlet/thermostat housing warps due to heat cycling, causing slow coolant loss and eventual overheating. Early 6T40 transmissions (2014-16) have weak torque converter clutch solenoids leading to shudder. After 2019, GM used an improved metal water outlet and updated transmission control module, drastically reducing incidence.
- #17-NA-145: Coolant leak at water pump / thermostat housing – affects 2014-2018.
- #16-NA-175: PCV valve cover replacement for rough idle & oil leak – covered under special warranty for some 2015-2016.
- #PIP5660C: Hard shift / delayed engagement – reprogram transmission control module (free for 2017-2019).
🛡️ Is the Chevrolet Trax Safe? Crashworthiness & Driver Assistance
Is it safe? Yes, with asterisk. IIHS gave 2015-2021 Trax “Good” ratings for moderate overlap front, side, roof strength and head restraints. However, small overlap front rated “Marginal” for driver leg injury risk. NHTSA overall: 4 stars. Best safety pack: 2020+ Premier trim includes forward collision alert, automatic emergency braking (AEB), and lane departure warning. If safety is priority, pick 2020 or newer with Driver Confidence Package.
✔️ Advantages & Disadvantages of Chevrolet Trax (Unbiased)
✅ Advantages
- Affordable ownership: Lower purchase price than Honda HR-V or Mazda CX-30.
- Excellent outward visibility: Thin A-pillars, high seating position.
- Decent cargo volume: 18.7 cu ft behind rear seats, 48.4 cu ft with seats folded.
- Fuel economy: 26/31 mpg city/hwy (real-world 28 mpg average).
- Easy DIY maintenance: Many parts shared with Buick Encore, cheap repair parts.
❌ Disadvantages
- Reliability lottery: Pre-2018 models high risk of engine & transmission repairs.
- Sluggish acceleration: 0-60 mph ~9.7 sec with turbo lag.
- Cheap interior plastics: Prone to rattles and scratches.
- Road noise: Poor sound insulation on highway.
- Rear seat room: Tight for adults over 6 feet.
🛠️ How to Choose a Used Chevrolet Trax: 8-Step Inspection
- Check coolant bottle & engine valley: Look for dried orange/pink crust – indicates previous cooling system leak (major red flag).
- PCV health test: With engine running, remove oil fill cap – if excessive suction or whistling noise, PCV is clogged.
- Listen for wastegate rattle: Rev to 3000 rpm and release – metallic rattling means turbo wastegate actuator worn.
- Inspect transmission shift quality: Test drive: feel for harsh 1-2 upshift and torque converter shudder at 35-45 mph under light throttle.
- Check engine oil level & smell: Burnt smell or low oil indicates oil consumption (common in 2015-2017).
- Verify recalls: Use NHTSA VIN lookup – many 2014-2016 had ignition coil and powertrain software recalls.
- Look for water pump replacement sticker: if repaired after 2019 (updated part), longevity improves.
- Pre-purchase inspection by GM specialist: Non-negotiable for 2014-2017 models.
Pro tip: The absolute best Chevrolet Trax year for used value + reliability is 2020. You get most of the fixes without the premium price of 2021-2022.

❓ Frequently Asked Questions (More Detail)
What is the most reliable year for Chevrolet Trax?
2021 Chevrolet Trax holds the crown for most reliable. It includes the final iteration of the 1.4L with the revised PCV, metal coolant outlet, and upgraded 6T40 transmission calibration. Owner satisfaction surveys indicate less than 3% reported unscheduled powertrain repairs within first 50k miles.
How many miles can a Chevy Trax last?
If you choose a best year (2020-2022) and maintain rigorously, expect 170,000-200,000 miles. 2014-2016 often need major repairs before 120k. Example: Many 2020 Trax fleet vehicles have crossed 140k miles with only fluid changes and a water pump replacement.
Which Chevrolet Trax years have transmission problems?
The worst transmission years are 2014-2016 with 6T40 units: delayed reverse engagement, harsh downshifts. 2017+ received TCM software updates that improve behavior. For maximum safety, choose 2019+ because they have updated valve body hardware.
Is it safe to buy a 2018 Chevrolet Trax?
Yes, the 2018 is the first “safe” year among early models. However, we recommend having the cooling system inspected (water pump and thermostat) as some early 2018s still had leftover parts. Overall, 2018 is a decent used option if price is under $11,000.
How often should I change oil on Chevy Trax to avoid PCV clogging?
Change oil every 5,000 miles with full synthetic Dexos1 Gen2 or Gen3. Do not follow the oil life monitor beyond 7,500 miles; extended intervals cause sludge that clogs PCV. Also replace PCV valve cover every 70,000 miles as preventive maintenance.
What are the advantages of Chevrolet Trax vs Honda HR-V?
Trax advantages: lower purchase price, simpler infotainment, better low-end torque for city driving. Disadvantages: worse reliability, smaller rear legroom, lower resale value. But for bargain hunters, a 2020 Trax with low miles offers huge savings over HR-V.
Does the Chevy Trax have a timing belt or chain?
1.4L Ecotec engine uses a timing chain (maintenance-free theoretically). However, some 2015-2017 models experienced premature chain stretch causing rattling. Listen for rattle at startup; if present, requires replacement ($1200-$1500).
