2021 Cadillac XT6 problems: recalls, complaints and whether this is a year to avoid
The 2021 Cadillac XT6 has 18 owner complaints on record with NHTSA, which ranks it 2 of 5 Cadillac XT6 model years by complaint volume. The worst year is 2020 (37); the cleanest is 2023 (13). 2 recall entries cover this year.
Is 2021 a good year for the Cadillac XT6?
Complaint volume is fairly even across this nameplate, so the model year is a weaker signal here than it is on many cars. Read the components below rather than the totals.
| Model year | Owner complaints | Recall entries |
|---|---|---|
| 2024 | 15 | 2 |
| 2023 | 13 | 2 |
| 2022 | 15 | 3 |
| 2021 ← this page | 18 | 2 |
| 2020 | 37 | 4 |
Older years have been on the road longer and collect more complaints for that reason alone, and a year that sold in higher volume collects more while being no worse.
The 2021 accounts for 18% of every complaint filed against the Cadillac XT6 in this retrieval, which works out to 3.6 complaints per year on the road across the 5 years since it was sold new — the figure to compare against other years, because it removes the advantage a newer car gets simply from having had less time to accumulate reports.
Complaints fell against the preceding year: the 2021 carries 49% of the 2020’s reports. Some of that is age, but a drop this large between consecutive years often marks a fix.
