While driving at interstate speeds in 90+ degree weather, the 2008 GMC Acadia experienced a complete loss of power. Engine quit along with all electronics, power steering and power brakes. Let car sit for 20 minutes and it started up and drove fine for a week or so then the same issue occurred again. This has happened 3 times within 5 weeks. The vehicle has been into an independent mechanic and two dealerships. Of those dealerships, we have taken the vehicle to the local autonation GMC dealer 3 times over the course of 2 weeks and all groups who have looked at the vehicle stated that they could not find and "codes" after running the computer diagnostics. We have requested an on-board diagnostic computer to be ordered from autonation GMC park meadows (co) but have received no response. This is a very dangerous issue while driving at highway and interstate speeds. Have researched other consumers with the same situation on the NHTSA website.

The service brake light and stabilatrac comes on every time you start the vehicle and sometimes while driving. Have not received a quote from the dealership yet. Will there be a recall that effects this or is it our problem to drop 1500 dollars to repair a manufacturer defect

While driving the stabilitrak off light, service brake system light came on. Upon taking it to the dealership they informed me that the master cylinder was leaking into the brake booster and both parts need to be replaced or the whole brake system could/would fail. This is a known defect with the GMC Acadia and could result in a serious accident/fatality. There was no indication of an issue due to an apparent defect in construction where the brake fluid does not leak externally, but rather internally to another component. This serious issue has the potential to cause catastrophic damage and should be recalled by GMC.

- Cincinnati, OH, USA

My vehicle began giving a stabilitrak notification. I took the vehicle in to identify the issue I was told by the GM service department that the master cylinder was leaking into the booster and would eventually cause the brakes to fail. Upon further research I have found several individuals who have dealt with the same issue. This is obviously a factory issue that is eventually going to cause injury or possibly fatality.

It had rained the night before and I came out to start my car and noticed that my driver side airbag was leaking water and there was a puddle of water on the floor board and water was dripping from my emergency brake. It has done this several times since then and I'm afraid my airbag won't work properly if I was ever in a wreck.

Stabilitrak system says it is "off" car makes a recurrent beeping noise, warning light to check brake system shows. Occurs randomly at any time of day. No leaks from car, still brakes well.

- Elizabethtown, KY, USA

The ABS warning light on my GMC Acadia has come on multiple times over the last couple of years. The problem goes away after adding brake fluid to the master cylinder. After searching online, this is an extremely common problem with GMC Acadia's, where the master cylinder leaks brake fluid into the brake booster. I am concerned that this is a major safety risk, because the vehicle will lose braking ability and at one point, the brake booster is not going to work due to the fact that it is filled with brake fluid. GM needs to stand behind its products... not just say that they are the "new" GM. This is a major safety hazard.

I have brought my vehicle in before our trip to massachussetts to the GM dealer in hastings, mn as the stop engine now/fuel pressure light kept coming on all the time. They told me that it is probably just a sensor issue. So I drove my car. In the last few weeks more lights came on such as traction control is out, stabilization needs attention, breaks need attention, and check engine. So they figured just more sensor issue. 9/9/14 I was backing out a parking spot with a friend of mine and my power steering was disabled and almost caused and accident when the break service light came on. Finally my husband took it back to the dealer to find that now I need a new timing chain and updates $2045, transmission control module w/solenoid $1226.58, and master cylinder and brake booster $690. They should have caught this before as GM is well aware of the issues according to complaints online and the service man who told me he sees this a lot. I noticed there is a recall on 2007 and 2009 for several of these issues. Had I not have my husband bring this in again I am sure there would have been a severe accident involving me and possibly my children. GM offered to pay for half the services but honestly they know this is an issue with their model. To tell people nothing is wrong, nothing is wrong and bam everything wrong at just 120K miles seems fishy. I want this fixed before someone gets hurt. I have a friend with the same model with many of the same issues. This is not fair to leave consumers in the dark considering this is vehicle mostly used by families.

I have had to replace a transmission on a car with just over 55000 miles. The windows leak when sitting outside in the rain. The power steering locks up when you drive thru a puddle. The braking system makes some god awful noise when going on or off a ramp. This was our very first brand new off the line car. Really wish we had waited until the bugs were worked out.

On February 2, 2011 my cars service brake system and stabilitrak lights came on and traction control turned off. Car was brought into dealer for diagnosis and repair. Master cylinder leaking break fluid into booster. If not fixed and brake fluid leaks further, brakes will fail. August 6th 2014, vehicle was brought back to dealer for same issues. Service brake system/brake lights on. Stabilitrak light on and traction control turned off on vehicle. SUV will loose brakes if all the brake fluid leaks into booster. Faulty parts pose a serious hazard as there is no evidence visual to the eye that break fluid is leaking. If breaks were to go out serious injuries and accidents would be the result. GM has been notified of the issue and will not stand behind their parts. GMC sees no problem in master cylinders and boosters failing after approximately 30,000 miles and therefore customers are faced with thousands of dollars of repairs. GMC won't take ownership to replace faulty parts that have gone bad repeatedly. 3 master cylinders and 3 boosters in a car that is only at 80,000 miles is a serious defect in parts. We are lucky brakes haven't failed 100% and killed innocent people because of GMC's negligence on fixing faulty parts that have been well documented on master cylinder and booster replacements.

Power steering failure again! 4/30/2010 at 23624, then 10/31/2013 at 80110, now only driven approx. 6,000 more miles and power steering is failing again May 2014. 10/31/2013 master cylinder also had to be replaced. I absolutely loved my Acadia for the first 50,000 miles, but ever since I started having transmission issues, this vehicle has turned to a money pit. I will never buy a general motor family vehicle again. Very disappointed with the short life of this american made vehicle.
