Common problems with the 2021 Trax

NHTSA's file holds 26 owner complaints on the 2021 Chevrolet Trax. Owners named the electrical system most often: 11 complaints. A complaint can name more than one component.

Mileage when owners reported a problem with the 2021 Trax

The 10 mileages owners gave run from 7,800 to 115,000 miles, and half are at or under 50,312. With fewer than 20 mileages this page gives the median only: the other percentiles are too few to say. 2 came after 100,000 miles, none after 150,000 and none after 200,000.

These mileages say when owners reported a problem, not when a 2021 Trax wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.

Most of these reports came early in the vehicle's life: 8 of the 10 came at or under 100,000 miles, so they say nothing about how many miles a 2021 Trax can cover.

Complaint mileage also follows a model year's age: the 2021 has had less time to cover miles than older years, so its figures will rise as it ages.

Is the 2021 Trax a good year?

Complaint counts cannot say whether the 2021 is a good or a bad Trax: they rise with how many were sold and how long they have been on the road. They show how the 2021 compares with the other model years in NHTSA's file.

With 26 complaints, the 2021 ranks 9th of the 10 Chevrolet Trax model years from 2015 to 2026 with 10 or more complaints, counting from the most. The most: the 2024 (184). The fewest: the 2026 (20).

Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.

2021 Chevrolet Trax recalls

NHTSA's recall files of November 11, 2026 list no campaign for the 2021 model year under the name TRAX. Recalls can be filed under another name (a trim, a body or a series name), so a recall may still exist for the 2021 Chevrolet Trax: check the VIN with NHTSA's free recall lookup.

What these figures can and cannot tell you

  • Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
  • The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
  • The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
  • They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2021 Trax lasts.
  • A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2021 Trax.
  • Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
  • 16 of the 26 complaints on the 2021 Chevrolet Trax give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
  • NHTSA name counted: TRAX. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
  • Recall-file name matched: TRAX.
