GMC Acadia problems by year

2024 GMC Acadia Caution

Brand-new third gen (larger body, 2.5L turbo, eight-speed): early owners report false automatic-emergency-braking activation and brake-module/pedal defects under recall. Typical first-year teething; evaluate carefully.

  • Brake defects: stiff pedal and longer stopping distances from a faulty E-Boost module/master cylinder, plus an electronic brake control module that miscalibrates pad wear (recall).
  • False automatic-emergency-braking activation, with the system stopping the vehicle for no obstruction, reported especially when reversing.

2023 GMC Acadia Recommended

Final second-gen year and the best-rated for reliability and owner satisfaction in the model's history.

  • Minor electrical, infotainment and stop/start complaints; overall volume is low for these settled post-refresh years.
  • Isolated engine and fuel-system reports; no dominant recurring mechanical defect in the late second gen.

2022 GMC Acadia Recommended

Among the best-rated Acadias (J.D. Power around 85/100) with minimal early defects. A strong used second-gen choice.

  • Minor electrical, infotainment and stop/start complaints; overall volume is low for these settled post-refresh years.
  • Isolated engine and fuel-system reports; no dominant recurring mechanical defect in the late second gen.

2021 GMC Acadia Caution

Settled post-refresh year with low complaints; a sound pick, held just below a buy by the nameplate's average repair costs.

  • Minor electrical, infotainment and stop/start complaints; overall volume is low for these settled post-refresh years.
  • Isolated engine and fuel-system reports; no dominant recurring mechanical defect in the late second gen.

2020 GMC Acadia Recommended

Mid-cycle refresh (new nine-speed and revised shifter) plus the lowest complaint volume of the generation make it the strongest used second-gen Acadia.

  • Minor electrical, infotainment and stop/start complaints; overall volume is low for these settled post-refresh years.
  • Isolated engine and fuel-system reports; no dominant recurring mechanical defect in the late second gen.

2019 GMC Acadia Caution

Reviewers consider it the first solid second-gen year as launch defects settle, though shift-to-park reports linger; below-average nameplate reliability keeps it short of a clean recommendation.

  • Six-speed automatic hard, harsh and jerky shifting with hesitation, especially on the V6.
  • 'Shift to Park' defect: the SUV fails to recognize Park, flashing the message and refusing to lock or shut off, leaving owners stranded (subject of a class action).
  • Assorted engine and accessory complaints on the new 2.5L four-cylinder and V6 during the launch years.

2018 GMC Acadia Caution

Shift-to-Park and transmission complaints persist (Consumer Reports rated it the least-reliable Acadia). Improving over 2017 but still a cautious buy.

  • Six-speed automatic hard, harsh and jerky shifting with hesitation, especially on the V6.
  • 'Shift to Park' defect: the SUV fails to recognize Park, flashing the message and refusing to lock or shut off, leaving owners stranded (subject of a class action).
  • Assorted engine and accessory complaints on the new 2.5L four-cylinder and V6 during the launch years.

2017 GMC Acadia Avoid

All-new downsized second gen launched rough: the 'Shift to Park' electronic-shifter defect (class action) and six-speed hard-shifting drove roughly 700 NHTSA complaints. The year to avoid.

  • Six-speed automatic hard, harsh and jerky shifting with hesitation, especially on the V6.
  • 'Shift to Park' defect: the SUV fails to recognize Park, flashing the message and refusing to lock or shut off, leaving owners stranded (subject of a class action).
  • Assorted engine and accessory complaints on the new 2.5L four-cylinder and V6 during the launch years.

2016 GMC Acadia Caution

Final first-gen year and among the most refined; minimal new defects beyond the Takata airbag recall, making it the pick of the Lambda Acadias.

  • Takata passenger-airbag inflator recall dominates complaints in the late first-gen years; confirm the campaign was completed.
  • Scattered electrical gremlins and HID headlight condensation on the refreshed Lambda; far fewer mechanical complaints than the launch years.

2015 GMC Acadia Caution

One of the better first-gen years with low non-recall complaint volume, though the Takata airbag campaign still applies.

  • Takata passenger-airbag inflator recall dominates complaints in the late first-gen years; confirm the campaign was completed.
  • Scattered electrical gremlins and HID headlight condensation on the refreshed Lambda; far fewer mechanical complaints than the launch years.

2014 GMC Acadia Caution

Much of the complaint volume is the Takata passenger-airbag recall (verify it was completed); mechanically a settled late-Lambda year otherwise.

  • Takata passenger-airbag inflator recall dominates complaints in the late first-gen years; confirm the campaign was completed.
  • Scattered electrical gremlins and HID headlight condensation on the refreshed Lambda; far fewer mechanical complaints than the launch years.

2013 GMC Acadia Caution

Mid-cycle refresh with the lowest first-gen complaint count; the 3.6L V6 and six-speed are better sorted, making it one of the stronger Lambda years.

  • Takata passenger-airbag inflator recall dominates complaints in the late first-gen years; confirm the campaign was completed.
  • Scattered electrical gremlins and HID headlight condensation on the refreshed Lambda; far fewer mechanical complaints than the launch years.

2012 GMC Acadia Caution

Last pre-refresh Lambda year: fewer steering complaints, but 3.6L timing-chain wear and aging electronics keep it a cautious buy.

  • Power-steering assist loss from pump and rack failures (leaks, whining); steering complaints peak in this window.
  • 3.6L V6 timing-chain wear and water-pump leaks (water pump covered by a 10-year/120,000-mile warranty extension on early units).
  • Six-speed automatic shifting problems and occasional failure carry over from the launch years.

2011 GMC Acadia Caution

Mid-cycle Lambda: power-steering and 3.6L engine issues persist though complaint volume falls. An average-at-best used pick.

  • Power-steering assist loss from pump and rack failures (leaks, whining); steering complaints peak in this window.
  • 3.6L V6 timing-chain wear and water-pump leaks (water pump covered by a 10-year/120,000-mile warranty extension on early units).
  • Six-speed automatic shifting problems and occasional failure carry over from the launch years.

2010 GMC Acadia Caution

Loss of steering assist is the headline (steering complaints peak), with timing-chain and water-pump risk on the 3.6L V6. Buy only with a documented service history.

  • Power-steering assist loss from pump and rack failures (leaks, whining); steering complaints peak in this window.
  • 3.6L V6 timing-chain wear and water-pump leaks (water pump covered by a 10-year/120,000-mile warranty extension on early units).
  • Six-speed automatic shifting problems and occasional failure carry over from the launch years.

2009 GMC Acadia Caution

Power-steering pump and rack failures dominate alongside lingering 3.6L timing-chain and water-pump concerns; transmission complaints ease from 2008 but reliability stays below average.

  • Power-steering assist loss from pump and rack failures (leaks, whining); steering complaints peak in this window.
  • 3.6L V6 timing-chain wear and water-pump leaks (water pump covered by a 10-year/120,000-mile warranty extension on early units).
  • Six-speed automatic shifting problems and occasional failure carry over from the launch years.

2008 GMC Acadia Avoid

The most-complained Acadia ever (850+ NHTSA filings): premature 6T75 transmission failure plus timing-chain, power-steering and airbag issues. Avoid without documented major repairs.

  • 6T75 six-speed automatic prone to premature failure: slipping, harsh shifts and complete breakdown, often a costly replacement.
  • 3.6L V6 timing-chain stretch causing a startup/acceleration rattle and cam/crank correlation codes that can lead to internal engine damage.
  • Takata passenger-airbag inflator recall affecting these model years.

2007 GMC Acadia Avoid

Launch-year Lambda Acadia: the 6T75 six-speed and 3.6L V6 timing chain drove heavy early-life transmission and engine complaints, with power-steering and Takata-era airbag recalls adding risk.

  • 6T75 six-speed automatic prone to premature failure: slipping, harsh shifts and complete breakdown, often a costly replacement.
  • 3.6L V6 timing-chain stretch causing a startup/acceleration rattle and cam/crank correlation codes that can lead to internal engine damage.
  • Takata passenger-airbag inflator recall affecting these model years.
