My car was purchased with a power lift gate in 2012. It has always worked fine until one day recently I was holding my young daughter putting a package in the trunk when it suddenly reversed its motion just as it was almost fully open and came slamming down on both my daughter and I hitting me, thankfully not my daughter right in the head. There was no way I could have gotten out of the way of…

What stands out
Owners have filed 39 body complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 8 model years of GMC Acadia in our records for body problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2012 Acadia has a serious defect in the power liftgate struts that can fail suddenly and drop the gate on your head or body with no warning—multiple owners report concussions, head injuries, and near-misses with children. Even after the recall repair, failures continue; if you buy one, budget for strut replacement and use the gate with extreme caution.
The dominant issue is power liftgate failure. The gate drops unexpectedly during opening or closing, moving fast enough to strike occupants in the head and neck. Owners report the gate opening normally then reversing violently mid-stroke, dropping 10–12 inches or more, or slamming shut with force. Several owners sustained injuries: one concussion after recall work was completed, one hit hard enough to lose consciousness and require hospitalization, another with severe neck pain. Injuries include headaches, dizziness, and head trauma.
The root cause is strut failure—parts that hold the gate open fail without warning. Some owners disabled the power function, only to find the manual gate weighs so much it cannot be operated safely. Multiple owners report their vehicle was not included in NHTSA Campaign 15V415000 despite having the identical failure, or repair parts were unavailable for months. One owner paid several hundred dollars out-of-pocket after the dealer denied coverage.
Secondary issues include the liftgate failing to latch, opening unexpectedly while reversing, and closing independently. Dashboard cracks were reported on one vehicle. One incident involved a rear door slamming with enough force to sever a finger at the hinge.

Failure modes owners describe
Power liftgate strut failure / uncontrolled descent
Liftgate struts fail, causing the liftgate to fall with force or slam shut without warning. Owners report the gate opening normally then suddenly reversing direction, dropping mid-stroke, or closing violently. Safety restraint system that should halt descent if obstructed fails to engage.
When: Occurs at various mileages: 19,000 to 187,000 miles; failures happen during operation while vehicle is stationary in driveway, garage, or parking
Symptoms owners cite: Liftgate opens then suddenly reverses and slams down with force; Liftgate falls or drops without warning mid-opening sequence; Liftgate closes independently with violence; Liftgate fails to remain in open position; drops under its own weight; Multiple recurring failures on same vehicle; No warning signs before failure; happens suddenly
Repairs/costs cited: Dealers identify failed struts and replace them; owners report repair costs of several hundred dollars; some dealers claim it is wear-and-tear not covered by warranty; part availability issues delayed recall repairs significantly
Recalls/TSBs owners mention: NHTSA Campaign 15V415000 (STRUCTURE) addresses liftgate strut failure; however, not all affected VINs included in recall; recall parts were unavailable for extended periods, preventing timely repairs; GM offered no cost assistance in some cases; GM claimed no open recalls exist for some owners reporting same failure
Liftgate power system malfunction / unexpected opening or closure
Electronic liftgate control fails, causing unexpected opening or closing without owner input. Gate may fail to latch, may open while driving, or may close unexpectedly when operator is in path.
When: Occurs at mileages ranging 29,000 to 187,000 miles; some events while vehicle reversing, others while parked
Symptoms owners cite: Liftgate opens or closes without button press; Liftgate fails to latch after closing; Liftgate opens unexpectedly while reversing; Liftgate closes unexpectedly on operator; No warning lights or indicators before failure
Repairs/costs cited: No repair costs cited in narratives; vehicle not diagnosed or repaired in most cases
Liftgate structural hold-up failure
Liftgate will not remain in the fully open position under its own weight or through power assist. Gate must be manually held or will collapse. When manual hold-open disabled, gate is unsafe to use.
When: Occurs at 29,000 to 60,000+ miles; failures apparent during normal cargo loading/unloading
Symptoms owners cite: Liftgate falls or drops when attempting to hold it open; Manual holding required; cannot open hands-free; Liftgate does not stay open with power button; When disabled to manual mode, door extremely heavy and unsafe to operate
Repairs/costs cited: Owners disabled power function due to safety; manual operation becomes nearly impossible due to weight and lack of support
Dashboard cracking
Dashboard develops cracks spontaneously without impact. One complaint mentions glare from chrome dashboard causing vision blur.
When: Failure noted at approximately 19,000 miles on one vehicle
Symptoms owners cite: Dashboard develops cracks; Chrome dashboard reflection causes temporary vision blur in sunlight
Repairs/costs cited: Dealer advised no repair available
Rear door slam / finger amputation hazard
Rear door closes with excessive force while vehicle parked on incline. No safety mechanism to prevent finger entrapment at hinge. One owner reports complete amputation of middle finger.
When: Vehicle parked on incline
Symptoms owners cite: Rear door slams with extreme force; No space between door hinge and frame to allow escape for fingers; Finger amputation reported
Aftermarket air deflector failure
GM aftermarket hood air deflector (Part 1927884) center plastic tie fractured at highway speed, causing deflector to strike windshield.
When: At 70 mph highway speed
Symptoms owners cite: Center plastic tie fractured; Deflector detached and struck windshield
Repairs/costs cited: Deflector not replaced

Common questions
How serious is the body problem on the 2012 GMC Acadia?
It's a meaningful issue. 39 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $1,500.
At what mileage does the body typically fail?
Across the 27 complaints that reported odometer mileage, most body failures cluster between 40,000 and 97,000 miles, with the median around 60,000. A quarter of owners report trouble before 40,000; a quarter make it past 97,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,500 for body repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to body?
No active recalls currently cover body issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
