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.
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.
