Brake Master Cylinder problems of the 2008 GMC Acadia

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.

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 trataction 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. Finially 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/selenoid $1226. 58, and master cylinder and brake booster $690. 00. 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 bamb 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.

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.

While getting repairs for my 35r wave plate (odi 10550736), the dealership told me that my master cylinder was leaking into the power brake booster and needed to be replaced. Like the 35r wave plate, this seems to be a common issue with the Acadia. I was told that if I did not replace the master cylinder, eventually, the brakes would fail.

The contact owns a 2008 GMC Acadia. The contact stated that while driving at various speeds, the brake warning lamp illuminated. The vehicle was taken to the dealer. The technician diagnosed that the master cylinder needed to be replaced. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 92,000 and the current mileage was 98,000.

F luid leaked from master cylinder to power booster no visible leaks repaired at my expense about a week later a bulletin from gm that was to extend my warranty to 10 year 120000 miles. There is a process in place to return my money. No safety recall ! both front struts have gone out . The air conditioner is causing problems because of off and on cooling. All of this is with in 55000 miles, the car has 55055miles as of this dated. There seems to be a process of no safety recalls but to issue extended warrenty. We all know what recalls do to sales.
