GMC Sierra years to avoid
Across the 2015–2022 GMC Sierra, the 2015 model year drew the most owner complaints to NHTSA: 814, about 1.8× the 460 median of the other seven model years with enough complaints to compare. It is also the oldest year in this comparison, and older years have had longer to accumulate reports. The most-reported components that year were the brakes and exterior lighting. The 2016 drew the fewest, at 48. Separately, the 2020 carries the most recall campaigns, 12. Complaint volume and recall campaign counts also reflect how long a model year has been on the road and how many were sold, so they rank years within this model rather than measuring build quality.
The 2015 Sierra is the outlier of the 2015–2022 GMC Sierra, with 814 complaints against the model's 509 median.
Every Sierra model year, ranked
Every Sierra model year NHTSA holds records for, most complaints first. Counts are NHTSA records as of 2026-09-15; recall campaigns and complaints are counted separately because a recall is the manufacturer acting and a complaint is an owner reporting. Years with enough on record have a page of their own.

|---|---|---|---|---|
| 2015 Sierra | 814 | 1.6× | 9 | the brakes |

| 2022 Sierra | 574 | 1.1× | 6 | the engine |
| 2021 Sierra | 558 | 1.1× | 7 | the engine |
| 2020 Sierra | 460 | 0.9× | 12 | the engine |
| 2017 Sierra | 427 | 0.8× | 5 | the powertrain |

- A higher count is not proof of a worse car. Complaint volume rises with sales volume and with years on the road.
- The comparison is between years of the Sierra only. It says nothing about how the Sierra compares with other models.
- NHTSA publishes owner reports without verifying them. A complaint is an allegation, not a defect finding.
- Recall campaigns cover production ranges. Only a VIN lookup shows whether one vehicle is included and whether the work was done.

GMC Sierra year-by-year questions
Which GMC Sierra year should I avoid?
Across the 2015–2022 GMC Sierra, the 2015 model year drew the most owner complaints to NHTSA: 814, about 1.8× the 460 median of the other seven model years with enough complaints to compare. It is also the oldest year in this comparison, and older years have had longer to accumulate reports. The most-reported components that year were the brakes and exterior lighting. The 2016 drew the fewest, at 48. Separately, the 2020 carries the most recall campaigns, 12. Complaint volume and recall campaign counts also reflect how long a model year has been on the road and how many were sold, so they rank years within this model rather than measuring build quality.
Which GMC Sierra year is the safest bet?
Of the 2015–2022 GMC Sierra, the 2016 drew the fewest owner complaints to NHTSA — 48, against the model's 509 median. Newer years have had less time on the road, which lowers their count on its own, so treat this as a starting point and check the individual VIN.
Do complaint counts mean the GMC Sierra is unreliable?
No. NHTSA complaints are unverified owner reports, and the count rises with how many vehicles were sold and how long they have been on the road. They are useful for comparing years of the same model — which is what this page does — not for ranking one model against another.
How do I check a specific Sierra?
Take the 17-character VIN from the windshield or driver-door label and run it through NHTSA's free recall lookup. That reports open campaigns for that exact vehicle, including whether the repair is still outstanding. A model-year page cannot tell you that.
