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.
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.
