Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2012 GMC Acadia Owner Comments

problem #3

Dec 102015


  • 30,000 miles


Sunroof leak driving during rainstorm water began pouring in on the driver side from the parking brake. Caused moldy smell, park brake on/off indicator light and brake on warning alarm now not working. Advised by glass co. And dealership that sunroof is causing leak from clogged drain lines and faulty seals. No recalls or tsb's but hundreds of other owners have had the same issue from 2008-2013 models. Ntsb should demand that GMC address this faulty product. Problem re-occurred during car wash following rain storm. Vehicle has only 30,000 miles, original owner, now out of warranty. GMC will not cover repairs.

The brakes and rotors have been to the dealership 4 times to fix them brakes are wearing down T the metal, brake slider sticking open, the last time it was to the dealership on July 2, 2014 I was told breaks are at current standards for measurements with law, to drive it for a few more breaks because two weeks prior to that they put new brakes and rotors are on, now they are grinding again, but have to wait to call and schedule another appointment because they say there is nothing wrong with them 4 times for the brakes to be fixed and they are not.
