Not inspected by anyone else because they have no idea where to look because the light and actions happen on and off. Warning light and message appears. Service Traction Control and service Stabilink Light yes I will bring it in. It will turn on randomly at this point for about 4 months and the brakes are locking up the wheels while driving.

I have a 2015 Acadia Denali with 95000 miles. I am getting the "service side detection system" message whenever I start my car, and the blindspot lights, cross-traffic detection etc. do not function at all. A"nationwide" problem I was told. I was also told that it would cost $800+ to replace if/when the part was available. I am really frustrated with this and was wondering a) whether this malfunction is a part of a service recall (given it is apparently a "nationwide" problem); b) whether the $800 replacement cost is accurate given that the part appears to be available for under $200 online; and c) whether purchasing this part will even fix the problem given that other forum members have stated that once this issue comes up, it continues to malfunction, even after the part is replaced. Very disappointed right now, particularly since this issue has been recurring on a number of GMC vehicles for at least 5 years.

Power liftgate suddenly fell about 3 ft, hitting the back of my head. The liftgate then forcibly closed, pinning my hand. There was a recall for 2008-2012 vehicles to due faulty Stabilus struts that cause failure. This is a serious defect that has already caused numerous head injuries, fractured hands, neck pain, etc. This recall needs extended and consumers need to know of the possibility. Lastly, the warning mechanism that GM claims is the presence of flashing rear brake lights and a chime to warn when liftgate failure occurs only happens AFTER the gate fails, not before. The warning is of NO use. Another consumer posted an exact same complaint in July 2021 for an Acadia outside of the current recall dates.

Rear lift gate when used goes up to a certain point in which you can start putting things into the car. Then it will slam down and then go back up and come back down in a forceful manner. When you attempt to control it manually it will close forcefully and yanked out of your hand. Biggest concern is if my kids were placing items in the car in which do realize things as quickly as an adult that it would crush my kids. After looking at all the information about this it has a recall open for the same thing in the 2008-2014 GMC Acadia.

Air conditioning issue: Within the first 5,000 miles, the rear air conditioning blower began to make unusual squeaking / vibrating noises. This continued intermittently for the until ultimately the entire car air conditioning system failed at 45,000 miles. The issue was brought to the attention of the certified GMC certified service center at 11 months of ownership/10,000 miles and 27 months of ownership/29,000 miles; they were unable to replicate the issue. At the 27 month visit the GMC certified service center (central Buick GMC of norwood) asserted this would be covered if the part subsequently failed. Upon failure, that service center refused to honor that commitment. Per GM service bulletin 16-na-046, the blower motor may emit brush dust that contains some copper particles. These particles could lead to accelerated corrosion to the auxiliary evaporator and a small refrigerant leak, which ultimately leads to failure of the air conditioning system. However, the GMC certified service center asserted that the failure of the system related solely to the failure of the rear auxiliary unit and entirely unrelated to any issues from that may have existed within the blower in contradiction to the service bulletin.

Air conditioner don't work right need to charge it every year. There is a leak in the system somewhere. Been a issue ever since I owe it and there is only 56,000 miles on this vehicle.

I have a 2015 GMC Acadia, I have had to replace the module to the side mirror safety lights twice. It has recently gone out again. I was told the wiring is shorting out causing the module to go out and the car to not run. GMC has a recall for this vehicle under 80,000 miles. My car currently has $127,000 miles because I drive it a lot for work. I contacted GMC and explained this has been replaced twice and is a safety issue that they know about and was told there is nothing they can do for me. I am a single mother and cannot afford to have this fixed again so I have no safety module for the side mirror or park assist. GMC knows this is a problem and that it was fixed once under 80,000 miles, again under 100,000 miles and now at 127,000 it is shorting out causing issues with the car to start and even with documentation from the dealer will not fix the car under recall. If GMC will not fix their safety issues they should not be allowed to marker these as safety features on the car, especially since they are aware of the electrical issues with the vehicle and chose not to fix the,

I was driving to work on the freeway and all of a sudden I heard a huge pop that sounded like a gun shot when I looked up my sun roof glass was completely shattered for no reason. After inspecting my sun roof I noticed the glass shattered from within I initially thought it happened externally on the vehicle but did not I believe there is defect in the glass I don't see how else this could have happened. In addition this is not the first problem I have noticed with the sun roof one day it was raining and I noticed that water had some how Sept in from the glass this caused damage to my lining in the vehicle that now shows water damage. I did not think nothing of it at first but seeing this happen now makes me believe there was is a defect in the sunroof.

At just under 1 year old the rack and pinnon went out. Replaced under warranty. Then at just over 3 years old it went out again on top of that for the last 9-12 months the engine will rev up and accelerate on it's own after it will chug for a bit then the sensor stabilitrak warning comes on then it will say traction control off then it will say its back on. I have also had it where it will looses engine power and you can barely get it to go when pushing the gas pedal. It's done this series of events about 10 times. It happens when driving, when in park, and while sitting at a red light. No rhyme or reason to it. But it is pretty unsafe when a vehicle will accelerate on its own driving anywhere! not to mention that a rack and pinnon should not go out 2xs in less than 3 years let alone on a vehicle that cost 45,000+ that was purchased to order brand new! these kind of costly repairs might I mention aren't covered under their power train warranty, though rack and pinnon is part of the steering component. Also this summer at less than 4 years old the ac quit working so I went in 90 degree temps with a baby and no ac until we had a chance to recharge it with refrigerant.

This could have been resolved under warranty, because at the time I had less than 36,000 miles but the car was at 38 months when the air conditioner went out and blowing warm air when the summer time temps were in the 90S. I took it to my GMC service dept and was told the evaporator needed to be replaced. The problem was it is a labor intensive repair that requires removal of the dashboard to get to the evaporator. $1500 later I now have cool air in the car I paid $40,000 for. After the fact I decided to search the web to see if this was a common problem, and it was. Barely 3 years old and the air conditioner needs major repair"? GMC should be ashamed of themselves! I have a 13 year old Chevy trailblazer with 168,000 miles and the ac works as good as the day I bought it. So, is this the new normal for GM" not good enough that cars today cost what you could buy a house for not long ago.now they build them to self destruct one system at a time to keep the profits rolling in.

My first incident on my 2015 GMC Acadia sle fwd purchased brand new was this year at 40000 miles. One head light went out and then the other in which the dealer wanted 400+ bucks to replace. The lighting is actually bad from the headlamps. They lights do not extended in front of you to see if you will be coming upon anything and can possibly run it over. My second issue at 41000 was the power steering. One day I heard a loud whining as I turned the corner on a city street and suddenly the power steering stopped. I looked in the manual and it says to put a certain type of transmission fluid in there, but I had just had a free oil change at the dealer about 3 weeks ago and they do not top off any other fluids. After putting the fluid in the power steering place, I noticed a leak. Come to find out the power steering pump is leaking on my car with only 41000 miles. A brand new car practically that cost 30,000 should not have issues so soon. Today, driving to work I almost lost it because my car all of a sudden started jumping codes "service stabilitrak; service traction control; traction control off; engine power is reduce' and my speed went from about 40 to 30 instantly. I was driving on a city street traffic while this happened and was unaware. Just think, if I did not put on brakes and was going at a certain speed and the person behind me is as well, and my car's speed just drop dramatically, what type of injuries could have occurred. I am very perturbed because this is the second GM car that I purchased with defects and my car just so happen to be omiited from any recalls. I own a 2010 Chevy Malibu as well and the power steering completely stopped working in 2015 and I had to pay 1300 to get it fixed, while other cars where on recall for the same issue. I'm so done with GM!!
