general problems of the 2011 GMC Acadia

We purchased the vehicle on August 20, 2025. At which time we paid over $4,800 for the vehicle. I will be trying to submit all files pertaining to the vehicle. We are both disabled and on the fixed income from ssi. However, a week after purchasing the vehicle all issues began to rise up. There was no transmission fluid, the oil need changed, catalytic converter showed up on autozone print out, wheels to make a sound when turning, brakes needs fixed, electrical seems to have an issue. The reason I am submitting this is in prayer asking for any remedy with this situation through the recalls, bulletins, and whatever else maybe available for the vehicle. I thank you for your time, effort, and consideration in this matter.

Tailgate system has failed causing tailgate to force closed after opening halfway. Risk of being pinned between the car and tailgate. Similar to previous recall power liftgate prop rod recovery, gate is not being controlled or caught.

The car it's equipped with a power liftgate and gas struts that hold the power lift gate when the rear trunk gate is opened, in my car the struts close prematurely an the open liftgate suddenly closes and causing injury.

My car has trouble starting often sometit takes almost an hour to get it started jump starting it does nothing battery tested good only a click as if battery is dead but still nothing.

Stabilitrak always reports off and brake warning always displays on dashboard, while on or running. Had it looked at by 4 mechanics. Breaks are fine. Engine wont start after everytime I pump gas. I have to pump accelerator sevral times for engine to start. Had it looked at again. Problem is ongoing. Also, slowed down on one occasion while driving on the hwy. Had to pull over since accelerator would not function. After 30mins or so. Was able to restart.

The liftgate unexpectedly falls. When it opens, it opens all the way, then it will unexpectedly fall at times.

Takata recall traction contro,l service stabilitrak, engine speed reduced light turned on in my 2011 GMC Acadia. Wouldn't go no faster then 15mph on a 55 mph road and the engine got really loud and rough. Was going 40 when the lights all came on driving down the road. This is very dangerous to drive when it keeps doing this. I'm scared to drive it now. Specially when I have a baby in the vehical with me. I'm not sure what causes it to do this. Some people say it's a glitch in the main vehicle computer, read it's a glitch in several different vehicals. This is something that seriously needs to be recalled and diagnosed and fixed immediately!.

Motor stops running while in movement in gears of forward and reverse. Driver has no control of the car. Steering works but no breaks or power to power train. Motor just shuts down with out any notice. This happens while in movement on public roads, freeways and while parking.

I had an accident in 8/6 where I place. My car in parking (p) and all of sudden a very accelarate noise came from the engine and locked me and my husband inside, we couldnt open the door and not even to turn off because the keya got stock in the ignation. Speed up over 30 miles an hour against a neighbor house causing damages and sending me to the hospital. . I want GMC to contact me ASAP. Fyi. The is video to prove it.

Our nite mare began December 2015 purchase of this vehicle has been in shop more then we've driven it , first thoughts on non starting was needed bigger battery, did that , second they thought battery issues again , an third time of non starting suppose able bad ground on transmission, did that, fourth time another ground on transmission bad, fifth time thought some thing electrical , put in some sort of transmission module , sixth time brain part, seventh time the back hatch an 8th time they have no idea its in shop still from August 4th last time drove anit lock brakes came on an slowed our speed from 55 to 30 we were all scared.

Steering wheel completely locked up during a turn a couple of weeks ago. Then last week I couldn't shift into reverse to get out of driveway. Had it towed to dealer. 1500. 00 later I have new shifter and some sort of new gears in steering wheel. Looked it up and there is a class action law suit with millions of people having the same problem, yet still not covered under a recall. My vehicle only has 48000 miles on it this should not have happened if there weren't some sort of defect in manufacture.

I went to open the back of my Acadia, pushed the button and as it raised I started to put a window in the back and the liftgate made a strange noise and before I knew it the liftgate started to come down while I was still holding the window. . . . It didn't stop even though it hit me and made my face hit the edge of the window and I had to push back really hard and then squirm my way out still holding the window. Prior to this happening, I have had no issues with the liftgate.

Hvac system failure for the second time in less than a year that lead to freon leaking into the passenger cabin of our 2011 GMC Acadia that has less than 44,000 miles. It was making an extreme hissing sound, followed by a misty cloud of freon gas, and now lets off an acrid, plastic/electrical burning smell that fills the cabin followed by steam rising from the engine compartment and the vents in the car's hood. The car starts to smell like it is on fire, only we can't find the source since it is obscured by the dashboard. We have had to the dealer several times for the same issue, yet all they do is upgrade the software and recharge the freon unit. It eventually leaks and shoots out freon into the faces of the passengers, which is not safe! now the burning smell has us concerned that we are driving a vehicle that is going to catch fire at anytime. We initially had gm and GMC repair this problem in October 2013, but the unit failed again exactly a year later in October 2014. There are dozens upon dozens of owners online that have well-documented cases with the same hvac unit. Something needs to be done before the car catches fire, and heaven forbid, kills someone.

Over the past month and a half I have been noticing that when I attempt to push the gas to make my car go faster that it doesn't accelerate. It is usually when my vehicle is already in motion and I attempt to go faster. I can hear it making a noise like it's trying to go faster but there is definitely a delay before the vehicle actually starts to go faster. Usually I am on a normal streets going anywhere from 35-55 mph (depending on the street and post speed limit), so it's not always a huge deal when it happens. I do a lot of highway driving and this is where my concern comes into play. A few weeks ago I was merging onto 696. There was more then enough room in the first lane for me to safely merge into traffice, however, when attempting to accelerate my vehicle it would not go above 35mph for a good 30 seconds and a car that was in the right lane probably going at least 70mph almost rear ended me. There was another instance when I was merging onto the vandyke expressway where the posted speed is 70mph and the exact same thing happened. Trying to merge into traffice with a post speed of 70mph and my vehicle not going above 35mph is not safe. My vehicle was recently in the shop because my air compressor literally melted and started smoking as I was driving my car. When it was in the shop this problem was mentioned to them and we were told "the problem would be like finding a needle in a haystack" the air compressor was fixed along with the current air bag recall, however, this accelaration issue was not addressed whatsoever. To me this is the most pressing issue and should have taken priority. I should be able to know that when I am merging onto a highway with fast moving traffic that my car is going to accelerate and not potentially cause a major accident.

My care skips as if the engine is not getting enough gas. I will be driving along and the Acadia will shake and do a little skip jump. It does this at least a couple of times a week. I also have to constantly add oil to the truck even when I am 1000 miles out from my next oil change.

Takata recall.
