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

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.

When we first purchased the vehicle the alternator went bad. The dealer replaced the alternator and battery for us. Then 6 months later the alternator went out again. They again replaced the alternator. Since then the vehicle has had a dead battery at least 4 times. Also noticed that when it rains you can hear water sloshing in the ac vents and then pours down from under dash on both the passenger and drivers side. Now my sound in the vehicle has started to cut on and off. This water issue is obviously leading to the electrical issues.

The sensor reading light continues to come on but doesn't match the area its stating. Took car to dealership for service and lights displaying now won't go off. I have replaced tires and air in the tires light still on. Found that to much pressure is in tires and they may burst.

I have been having problems with my vehicle for a while now. The car will cut off in traffic I have gotten stuck in the seatbelt as well as today while I am trying to make a left the car would not accelerate as I was hitting the gas pedal I could have been killed. I have taken my vehicle to [xxx] on another occasion because I had just left the gas station filling the tank up I got in the truck pulled out of the gas station and the gas gauge started going up and down my overhead lights came on and the car just died out in 45 mph traffic I took it in and all they keep telling me is if they can't duplicate the problem they can not help me how is this safe number one number two I do not know when the vehicle is going to cut off. I have had the speedometer just go up and down as I'm driving as well as the radio would just start to shift from auxiliary to cd to radio without ever being touched. If I hit a pothole lights start flashing this is unacceptable. But I'm being told there is nothing that can be done because they can't replicate the problem how is this on my shoulders I'm paying for an extended warranty that is not worth the paper it's printed on. It has to be an electrical short or something they just do not want to repair. But I can not keep putting my families lives in danger driving this vehicle because they say they can not replicate the problem. This is dangerous and GMC will not help.

The contact owns a 2012 GMC Acadia. While stopped at a traffic light, the driver seat moved and adjusted on its own when the accelerator pedal was depressed. The seat moved backwards and further away from the steering wheel. The contact stated that the seat slid and tilted. The failure recurred several times. In addition, the contact stated that the vehicle made an unusually loud noise when the remote engine start feature was activated. The dealer was unable to diagnose the cause of the failures. The manufacturer was notified. The approximate failure mileage was 10.
