GMC Acadia Denali
Problems & Worst Years
Every reported problem for the GMC Acadia Denali, model year by model year — ranked from 505 federal NHTSA complaints across 2015–2017.
Airbag system failure defines the early years of the GMC Acadia Denali in this data, before an entirely different defect takes over in 2017. The 2015 model year logs 108 occurrences across 9 problems, two safety-rated, split almost evenly between two overlapping descriptions of airbag system failure — 40 reports under one wording, 35 under another — plus 8 reports of power steering pump failure and a handful of electrical wiring and lighting complaints. 2016 carries the airbag theme further with 60 reports specifically describing delayed or unresolved airbag recall issues, its single largest complaint category out of 146 total occurrences, alongside 24 reports of transmission malfunction, 16 of electrical failures affecting the side detection system, and continuing power steering pump complaints.
2017 is a different story entirely, and the worst year by far for this model: 495 total occurrences across 17 problems, more than triple the prior year's volume. Almost all of it centers on the vehicle failing to shift into or recognize Park — 100 reports of inconsistent shifting to Park, 99 of a shift-to-park warning appearing while already parked, 92 describing the vehicle simply failing to recognize Park position, and another 46 and 38 describing variations of the same transmission shift-to-park failure. Together these five categories account for the overwhelming majority of everything reported against the 2017 Acadia Denali.
For a 2015 or 2016 example, confirm that any airbag-related recall work was actually completed rather than merely scheduled, since owner reports specifically flag delays and parts shortages. For a 2017, the priority is entirely different: test, repeatedly, that the vehicle reliably shifts into Park and shuts off normally — this was clearly the dominant owner complaint that year, not a minor quirk.
None of this amounts to a blanket condemnation; these are the top-reported issues in NHTSA's complaint data, not a guarantee of failure, and the usual caveat applies — a pre-purchase inspection and documented service history on the specific vehicle matter more than these aggregate year-by-year counts.
