Owners have filed 401 complaints
about the 2012 GMC Acadia with NHTSA between 2012 and 2026.
The largest single group is the steering.
Across this model's run it ranks 10 of 20 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 52
Against the median year of the GMC Acadia. 50 means typical for this
model; 100 means roughly double.
Severity — 45
8.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 31
18% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2012 GMC Acadia
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Outboard Front Seat Belt Anchor Cable Failure
On August 31, 2020, the Office of Defects Investigations (ODI) opened Engineering Analysis (EA) EA20002, as an upgrade of Recall Query (RQ) RQ19003. This investigation, related to recall 14V-266, was opened to investigate instances of detachment of the flexible steel seat belt anchor cable attached to the outboard side of the front seats in vehicles manufactured by General Motors (GM). The subject vehicles included model year (MY) 2009 through 2014 GMC Acadia, Buick Enclave, and Chevrolet Traverse SUVs as well as MY 2009 through 2010 Saturn Outlook SUVs. These vehicles were previously repaired...

Seat Belt Anchor Cable Failure
On May 19, 2014, General Motors LLC (GM) notified the Office of Defects Investigation (ODI) that it would conduct Safety Recall 14V266 to address fatigue and separation of the flexible steel cable that connects the front outboard seat belts to the seat-mounted belt pre-tensioner in 1.4 million model year (MY) 2009-2010 Saturn Outlook, 2009-2014 Buick Enclave, GMC Acadia and Chevrolet Traverse (Lambda Platform) vehicles.The remedy was to inspect for signs of damage and replace pre-tensioner anchor cables as needed.

Recalls on the 2012 GMC Acadia
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 20194205,327 units in Canada
Other
Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.
Recall 201528036,369 units in Canada
Structure
On certain vehicles equipped with a power liftgate system, the gas-filled struts (which help to raise and support the liftgate) may prematurely wear. These vehicles have a Prop Rod Recovery system intended to accomplish a controlled, slow return of the liftgate to the closed position if the liftgate’s gas struts are no longer capable of supporting the weight of the liftgate. The vehicle would provide audible warnings and flash the tail lamps to indicate there is a problem. However, the liftgate’s Prop Rod Recovery system software may be unable to detect/stop a liftgate with prematurely worn gas struts from falling too quickly after the liftgate is opened. This could allow the liftgate to drop suddenly, placing anyone beneath or near the gate at risk of injury. Correction: Dealers will reprogram the power liftgate actuator motor ECU with a new software and will verify power liftgate operation following the reprogram.
Recall 201418175,701 units in Canada
Seats And Restraints
On certain vehicles, the flexible steel cable that connects the seat belt to the vehicle structure at the front outboard seating positions can fatigue over time and could separate, increasing the risk of injury in a crash. Correction: Dealers will inspect and repair or replace the lap pretensioner, as necessary.
Recall 201408170,526 units in Canada
Airbag
On certain vehicles, side airbag wiring connections could develop high resistance, illuminating the airbag warning light. If the vehicle continues to be operated in this condition, resistance may continue to increase over time and eventually cause the seat side airbags and seat belt pretensioners to not deploy in the event of a crash, which could increase the risk of injury. Correction: Dealers will affect repairs.
Recall 20121225,810 units in Canada
Visual System
On certain vehicles, if a buildup of snow or ice on the windshield or on the wipers restricts the movement of the wiper arm, the wiper arm nut may loosen and cause that wiper to become inoperative. Loss of windshield wiping capability, should it occur during a rainy/snowy day, may compromise the driver's ability to see the road and its users, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will tighten the wiper arm nuts.

STRUCTURE:BODY
The back seat driver's side door shut with such impact as to amputate the finger from an adult. Vehicle was parked on incline when front driver's side door shut, the back door also shut. There were no safety features to protect fingers from the hinge side of back door. The force of the door slamming and lack of any space between the hinge side of the door and its frame caused my middle finger from the top knuckle up to be cut off completely thus amputated from hand.

STRUCTURE:BODY
The power liftgate suddenly collapsed while I was standing underneath it. It dropped on top of my head pretty hard as it was a sudden drop of the liftgate. My safety was/is at risk and has caused injury to my head. Currently experiencing headaches. As condition progresses, I will be seeking medical attention. It is available for inspection. I have recorded a video of the problem. The problem is recurring and reproducing. I have not taken it to a dealer or independent service center today (9/13/2021 date of incident) as the weather is bad in my area (experiencing high rain and winds from a tropical storm). I will have it taken in on 9/14/2021. The vehicle has not been inspected by anyone. There were no warning indicators or other symptoms prior to the initial collapse.

POWER TRAIN
Was waiting on dealership to catch up to bring in for a transmission problem. I know it is transmission related due to not wanting to shift properly and the fact my friend has same make and model only about 100000 more miles than mine does was doing same symptoms and she took to 3 or 4 mechanics and all said nothing wrong..no codes show up...needless to say after about 2 months it stalled out on her on interstate with speed limit 75 and she barely moving. I myself was at a sharp curve in turn lane waiting on traffic and when I braked to stop it made horrible sound and felt like brake was pushed through floorboard. When I was clear to go i push accelerator down to the floor and am barely inching along and am now stuck in the road in a 90 curve where its hard to see traffic coming. This was very scary and traumatic having this happen. I'm just glad it was only myself and the other drivers were being observant and paying attention to the road. This has happened a lot compared to research on blogs car complaints websites. The common problem is it doesn't give a code when diagnostic checked. 99% of cases show they best guess or find something else wrong and you pay 3 or 4 charges until you finally convince them its the transmission and then you're out 5000. Not counting the average 4500 you've already pd due to not listening to the driver of their vehicle and causing unnecessary charges and leaving you without a vehicle too long that isn't necessary.

EXTERIOR LIGHTING
Daytime Running light bulb and housing failure. Some 2012 Acadia models recalled under now expired recall for bulbs and deformation of surrounding housing. Apparently the above recall was excluded from this recall and should have been included. Both DRL on this vehicle have failed and surrounding housing has been damaged . Subsequently replacing just bulbs is not possible. The housing melted on the bulb. Photo is available on request. This failure should be considered a fire hazard. GM customer service center stated to me that this vehicle was not included in recall after VIN search. Some 2012 Acadias were in fact included , this one was not. And should have been since the failure occurred as stated in the original recall.

This 2012 GMC Acadia denali with close to 160k has been in the shop several times due to it randomly stalling out It kept basically locking me out from starting the car a "service anti-theft system" would flash across the dash followed by a flashing check engine light along with a lock and key symbol. A local GM repair shop had it in 3 times for them to tell me they couldn't figure it out or get the vehicle to "act up" they cut me two new keys and tightened up what they claimed to be loose battery cables just for the vehicle to die/stall with a no crank no start happen literally 10 minutes down the road after paying almost 600$ for repairs and that it was towed back 3 times for the same issue spanning over two months of them not being able to figure out the issue. Salvador ended up replacing the anti-theft control module after the 3rd time having to tow it back and forth just to leave the shop and I couldn't start the vehicle the next day after handing over almost another 400$ and less than 15/20 miles of drive time. GM needs to get this issue figured out!!! There anti-theft system locks people out from starting their vehicles more than it does actually preventing actual theft. This will eventually end up causing a major crash at an intersection or highway if the anti-theft system keeps failing it just randomly cuts out power to the engine while driving.
