Mileage when owners reported a problem with the 2020 Impala
Too few complaints on the 2020 Impala list a mileage to say when owners reported problems: 3 of its 15 complaints list a mileage (40,433 to 85,000 miles), and a median is given here only with 10 or more.
These mileages say when owners reported a problem, not when a 2020 Impala 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.
Every model year together: Half of the 7,573 NHTSA owner complaints on the 2000–2020 Chevrolet Impala that list mileage came after 69,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Chevrolet Impala last? →
Is the 2020 Impala a good year?
Complaint counts cannot say whether the 2020 is a good or a bad Impala: they rise with how many were sold and how long they have been on the road. They show how the 2020 compares with the other model years in NHTSA's file.
With 15 complaints, the 2020 drew the fewest of the 21 Chevrolet Impala model years from 2000 to 2020 with 10 or more complaints. The most: the 2004 (1,074).
NHTSA files the Chevrolet Impala name for 1994–1996 and 2000–2020. A gap of three or more model years means the name covers different vehicles, so the 2020 is compared only with the 2000–2020 model years.
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.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2000 Impala | 818 | 417 | 86,000 |
| 2001 Impala | 741 | 475 | 80,000 |
| 2002 Impala | 795 | 570 | 78,000 |

2020 Chevrolet Impala recalls
NHTSA's recall files of November 11, 2026 list no campaign for the 2020 model year under the name IMPALA. Recalls can be filed under another name (a trim, a body or a series name), so a recall may still exist for the 2020 Chevrolet Impala: 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 2020 Impala 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 2020 Impala.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 12 of the 15 complaints on the 2020 Chevrolet Impala 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: IMPALA. 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: IMPALA.
