We've had electrical issues beginning about 2 years after buying the Acadia. Currently the check engine light stays on. We had it checked at the dealership and were told that it was safe to drive. The problem was probably part of the electrical issues. Well, it wasn't. now the steering is difficult (and locks up at low speed turns) and the stabilitrek message comes on. We took it back to the dealership today and have been told that we need to pay for repairs to service the brake system, stabilitrek message, replace the brake power booster and master cylinder, and repair the tire pressure system light and sensor. They think this may fix the steering issue, but if not then they'll look more into that! I know there are at least 195 service bulletins for this year model Acadia. We bought it new. It's seven years old with low mileage. They said it isn't safe to drive except in town at low speeds. I feel like we're being given the run-around by GM via our dealership. It's never been in an accident (other than knocking off the side mirror upon exiting the garage), and it's not driven in a rough-shod manner. Ugh! I've owned several vehicles, new and used, and never had trouble like this. My daughter is the primary driver of the Acadia, so safety is of the utmost importance.

My car completely died while driving it a few months back. Just got it back after about 3 months, partial sucky dealership, partial back order issue. Turns out the sunroof leaked into the dash. Had to replace the body harness and something with the dash. $5100. I estimated on the date it happened because it's been awhile.

My vehicle turned off while driving on a side highway, and was unable to be jump started. Took it to a mechanic and found the ECM was bad. Mechanic called different dealerships to price an ECM, and was told by each dealership that this is a common problem. He was informed that even with a new ECM installed, it may go out in another year.

2 months after I bought my vehicle used I have had to replace ignitions coils, so many recalls and only had some replaced cuz of being told they don't have the part in store at the dealerships. The electrical system for heat and A/C don't match up when turning the knob and the defrost doesn't work 3/4 of the times. I get flashes of loss power and my tire monitoring system keeps acting up. Now my engine and transmission are failing and no one can tell me exactly what it is without paying $5000 for them to diagnostic it and take it apart!! where do I have that kind of money"? this vehicle was the worst $16000 I have ever invested in and have only had it less that 2 years!! I am scared on a daily basis to drive my kids anywhere in it let alone myself to work. I so wish I would've kept my Jeep Grand Cherokee but we need more room for travel. Well you can't travel in something that's unsafe and unreliable. GMC won't call or respond back and either will the dealership. Lemon law in Michigan is for new vehicles only so I am basically paying for something I can't drive and I can't afford to fix. What do I do?"

I have continued to have issues with the steering in my Acadia. We called the dealership and described the noise it was making and they said it was normal and it was just the 4 wheel drive kicking in. Now the steering is completely out. We were in a busy parking lot when it happened and almost hit a pedestrian as the steering went out as we were turning left. The car was moving slowly at the time. I am now seeing several forums where others are having the same issue. There is even a pending lawsuit. There is also an issue with the electric where the safety power locks do not work. My son has opened the door when the car was moving because of this. I have had 5 recalls on this vehicle, so it's hard to keep up with all the issues.

I took my 09 GMC Acadia to the GM auto to fix the transmission and they told me they can not fix unless I pay the $2043 to fix my power steering, but I believe its all related to that power steering failure that is cover under the GM policy. And its the same problem to all the Acadia that are out there so I suggest the GM to fix all GMC Acadia without any cost to all the owneri if they fix it right we wouldn't complaint at all

The contact owns a 2009 GMC Acadia. The contact stated that the day time running lights failed on several occasions. The contact indicated that the sockets and housing failed to support the power for the lighting wattage, causing the components to prematurely melt. The bulbs were replaced more than twice. The vehicle was taken to the dealer, who recommended that the housing be replaced for the day time running light assemblies. The failure recurred with both lights shorting. The dealer, per the contact's request, disconnected the day time running lights to prevent the failure from recurring. The vehicle was not repaired. The manufacturer was notified of the failures and provided no remedy. In addition, the contact experienced the rear liftgate closing with force, which bruised his head. The contact received notification of NHTSA campaign number: 15V415000 (structure) but was waiting for months to determine when the manufacturer would be able to supply the remedy and the part to repair the vehicle. The approximate failure mileage was 47,274. Updated 11/20/15

Car stalls as I am turning into parking spots, turning or going around significant curves in the road, while im in a round about etc. Luckily I have been able to put the car in neutral and it starts back up and off I go. I am the second owner of this car and I bought it from a non GM dealer. My mechanic is at a loss as to what is wrong because a) there are no codes that are coming up and B) the stalling is very sporadic, it will do it twice in one week and then not do it again for 3 weeks. I have had this car about 5 months and it has happened about a dozen times. I pulled the carfax and called the dealership that did all the work on it with the previous owner. After speaking with the service department, I was told that the previous owner had the same problems and the dealer could not get the car to malfunction while they had it in for servicing. Although she didn't tell me everything that they did to try and resolve the issue, I do know that they went as far as to replace the cylinder head hoping that would solve the issue, but clearly it did not. This is a very dangerous safety issue, I have almost hit several cars due to the fact that when the car stalls, everything locks up and you have no control over anything.

Incident (first big symptom): Braking and slowing to yield sign from offramp/ steering felt as if ignition turned off and car became much less stable in steering with a stiffening and rattling/tapping noise somewhere just left to the center of the steering wheel. Once trying to turn realized there was no power, thought the engine had stopped running and then hitting the gas the steering suddenly pops back into assist. This is a very unsettling first occurrence that I see on multiple internet sites has been happening since at least 2011 in many different versions of this chassis. It would have been nice to have known this before two things: 1. before I had my four daughters and the neighbors kid in my car to put at risk of killing them ( GM shame on you as you this problem exists for 4 years) 2. before the warranty was one month out of contract. The dealer states this is "unusual to them', they have not heard of it happening and do not think it is unusual that a vehicle with only 58000 miles on it has the entire steering pump, gear, and rack assembly blow seals. Repair costs are quoted at $2000. Need to replace rack, pump and something else. Additionally, there are 56 posts relating to steering alone. Some of us driving these vehicles feel that being able to have a chance of piloting the car safely may be important. I used to think my dad was silly when he would say something is a poor design, but did the engineers actually do any testing on these vehicles" do you test the problem or just keep saying it's not happening" thank goodness this is all low speed and no one has died yet ( at least that we know of).

Various GM vehicles have a known defect that allows water from the sun roof drain to enter the passenger compartment and more importantly allows water to enter the passenger compartment fuse block. This defect is covered under service bulletin #08-08-57-003C. This vehicle has had numerous electrical system issues that only occur during heavy rains and the dealer has been unable to recreate the problem after things have dried out so to speak. Most recently after a heavy rain, the battery was dead and when replaced with a new battery, the engine would not shut off even after the key was removed. This is a serious safety concern that can result in injury or death. The only way to shut off the engine is to remove the ECM fuse from the under hood fuse block. Not being able to shut the engine off via the key can have serious life consequences in the event of an emergency. This is a wide spread issue that seems to get worse over time and ends up with not being able to shut the engine off. The GM models affected by the service bulletin as follows: 2008-2012 Buick enclave 2007-2012 GMC Acadia 2007-2010 Saturn outlook

Passenger side low-beam headlight failed. Upon inspection, it appears the light socket itself has melted and caused the wiring shielding to melt as well. Attempted replacement of the bulb resulted in the socket housing crumbling in my hands. The dealer claims it will cost upward of $500 to change my lightbulb. This is outrageous and clearly the fault of GMC, who seem to have purposely designed these bulbs to overhead their housings, melt, and be almost impossible to change without taking the vehicle to the dealer. I want GMC to pay for new wiring and illumination.

Acadia 6-cyl

  • 45,000 miles
The daytime running bulbs next to the headlights overheated and melted the back of the housing that the bulb socket mounts in the back of the headlight housing. Obviously there is a design defect in the socket/harness that is causing overheating. There is a technical service bulletin on this for 2009 Acadia and other makes with the same design but this is a safety issue as it can cause a fire and also the lights can short out. The bulletin is #10-08-42-001: Low beam headlamp bulb diagnosis/replacement (inspect bulb and connector) - (May 14, 2010). This needs to be recalled.

The vehicle is equipped with a gear driven power liftgate that opens and closes the rear hatch at the touch of a button. I approached the rear hatch of the Acadia to load groceries, and signaled it to open. The hatch powered open normally to its full height. I walked underneath it. With no warning, the hatch suddenly fell and struck me in the head / back of neck / shoulder area. It hit hard enough to cause serious injury.

Acadia 6-cyl

  • 40,000 miles
The headlight went out and GMC quoted me at approximately $120 to replace. Husband attempted to replace it but you had to take off the wheel in order to get to the actual light. I gave GMC the go ahead to replace and they called me back and told me that the wiring had melted and that it would now be over $300 to do it. I told them no and made a complaint. They called me a few days later telling me they would do it but I had to pay $50 deductible (assuming they went through some type of warranty). It eventually became a recall and I am now looking into getting reimbursed for my $50. Noticed my car started over heating and took it into a mechanic friend, let us know that the water pump needed to be replaced this was at approx 45,000 miles. I did my research and the GMC warranty covered the cost. At approximately 56-57,000 miles the car started making a whining noise when driven slow or first thing in the morning when it was cold. Took it in to GMC to get it checked out and it turns out that the steering rack had a leak on each side of the wheels and pinions, and power steering pump needed to be replaced. Quote almost $1500 dollars. I could not afford that price so took it back to my mechanic to see if it would be cheaper. He ended up replacing the pinions and rack but said the pump did not need to be replaced and ended paying $600 out of pocket. I'm hoping that GMC will see that many of us are having the same problem and will make it a recall. I will not be buying anymore GMC vehicles. All I want is a reliable car that won't break the bank.

The driver side low beam headlight went out. When replacing the light bulb found that the wiring connector was partially melted and one of the wires was hanging out. The insulation on that wire was also melted off so bare wire was exposed. The original bulb also had a burnt spot where the connector attaches.

Driver side low beam headlight bulb went out. Purchased bulb to replace myself, but discovered harness was burnt. I then took to shop to have harness replaced. They told me it looked like something that should be a recall and told me to report and keep receipt of cost to replace. Now I am concerned about the left bulb and wonder if I should go ahead and pay again to get that replaced for safety precaution.

Wiring harness to passenger side low beam headlight is defective. Thought bulb was out but after inspection found the wiring harness plug had completely melted where plugged into bulb. One wire was just hanging and could see burn marks where it had been arcing as it bounced around. Could definitely have caused much bigger problems than driving with one headlight I.e. fire, shorting whole electrical system, and on and on. This is a very big safety concern. These were the oem headlights not aftermarket bulbs that pull more current so should not have melted the harness plug.
