2021 Chevrolet Trax: what breaks, and at what mileage
What breaks on the 2021 Chevrolet Trax
On the 2021 Chevrolet Trax, the failure owners report most often is other engine problem, with 5 reports on file. Across every failure mode on this year, half the dated reports were filed before 70,000 miles. Overall it scores 66 out of 100, high risk for a 2021.
High risk for a 2021 — 197th riskiest of the 231 2021 vehicles we can rate. 39 owner reports; fleet size borrowed from other years of the same model.
The failures owners actually file about
Owners have reported 20 named failure modes on the 2021 Chevrolet Trax, and the three most-reported carry 28% of everything filed, which is an unusually even spread for one model year.
Other engine problem leads with 5 reports and about 0.2 per 1,000 vehicles.
Complete engine failure or seizure follows with 3 reports, median 70,000 miles.
Head gasket failure follows with 3 reports.
By system, the reports fall mostly into engine (15), electrical (4) and brakes (3).
When these failures get reported
8 of the reports on the 2021 Chevrolet Trax came with an odometer reading, and half of those were filed before 70,000 miles.
Cumulatively, 38% by 50,000 miles of the dated reports had been filed.
The busiest stretch is between 0 and 10,000 miles, which alone holds 25% of the dated reports.
25% of the dated reports were filed below 36,000 miles.

What happens when these parts fail
Across the named modes, 5 mention a crash, 2 a fire and 2 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 5.82, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other engine problem at $300–$4,000, complete engine failure or seizure at $4,500–$12,000, head gasket failure at $1,400–$4,000 and misfire or rough idle at $250–$1,600. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
44% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2021 Chevrolet Trax draws about 1.4 per 1,000 vehicles, which puts it in the 75th percentile of complaint rates among 2021 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model.
The working figure is 28,177 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2021 vehicles, which is what the risk score uses, is far more robust than the rate itself.
How it ranks in the 2021 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.

- Right more, or worse

How 2021 compares with the other years
High risk for a 2021 — 197th riskiest of the 231 2021 vehicles we can rate. Because the ranking is against the same model year only, age cancels out of it.
Across the 10 model years of this car that carry enough reports to score, 2026 comes out best at 65 and 2019 worst at 77, with 2021 itself at 66.
No other year of this model scores meaningfully better than 2021, so if this generation is what you want, the year is not the lever.
Within the 2018–2022 generation specifically, 2021 is the strongest year at 66 and 2019 the weakest at 77.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2018-2022 generation, 2021 Chevrolet Trax scores best at 66 and 2019 Chevrolet Trax worst at 77.
Where these figures stop being useful
39 owner reports; fleet size borrowed from other years of the same model. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 39 reports, 8 carried an odometer reading, so the mileages here describe 21% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 2021 Chevrolet Trax?
The most-reported failures are other engine problem (5 reports, median 10,000 miles), complete engine failure or seizure (3 reports, median 70,000 miles) and head gasket failure (3 reports). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Is the 2021 Chevrolet Trax reliable?
It scores 66 out of 100 on our risk index, which is high — 197th riskiest of the 231 2021 vehicles we can rate. The score is a comparison against other 2021 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.
Which year of the Chevrolet Trax is best?
Within the 2018–2022 generation, 2021 scores best at 66 out of 100 and 2019 worst at 77. Same body, same engines, different luck.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
