Head gaskets and engine default and ground wire system defaulted.
The air bags light came on with no reason truck never being in a crash, the abs and the off road light is on too, the break lights are on while you don't step on the pedal and they go off when you step on it...
The headlights don't work even after replacing. It rains in the vehicle from the sunroof. The gas tank isn't registering even after fixing it. So the engine doesn't know how much to put out etc etc and it makes the car jerk horribly. This vehicle is a fire hazard due to raining inside on everything upfront. I have kids I pray nothing happens!!
Well my back trunk doesnt worrk well i open it but it closes half way it almost closed on me and its done that more then 3 times and im not sure why its scary cause my child almost got hit with it not opening right.
Vehicle has a sunroof drainage issue. Water leaks in through the corners of the sunroof and spills into the dashboard and under the carpeting. The vehicle has suffered electrical damage, corrosion, and mold because of the sunroof drainage issue. I have seen forums with hundreds of other owners who have suffered the same exact sunroof drainage problem with their 2007-2008 GMC Acadias. GMC says my vehicle is not listed in the recall, but I find that laughable. There are way too many Acadia owners that have this exact issue for it not to be a problem with all Acadias.

MY PASSENGER AIRBAG LIGHT HAS BEEN ON SINCE I GOT THE CAR IN MARCH OF 2020. I HAVE JUST REPLACED MY LOW BEAM HEADLIGHTS OCTOBER OF 2020 AND NOW THE DRIVER SIDE LIGHTS DOESN'T WORK. ON THE DASHBOARD THE LIGHT THAT'S SUPPOSE TO SHOW WHEN YOUR BRIGHT'S ARE ON, DOESN'T COME ON ANYMORE AND I WAS IN MOTION WHEN I REALIZED THEY HAD STOPPED WORKING.
BOUGHT THIS VEHICLE USED, WAS FINE AND WAS A GREAT CAR FOR MONTHS UNTIL THE BATTERY WOULD NOT KEEP A CHARGE. TOOK IT TO AUTO ZONE THEY TESTED MY BATTERY AND ALTERNATOR ALL WAS GOOD THEY CHARGED UP MY BATTERY FOR ME. THE BATTERY LASTED TWO DAYS NEXT TIME I WENT TO START IT IT WAS DEAD. WOULD HAVE TO DRIVE IT EVERY DAY TO KEEP A CHARGE ON IT. EVENTUALLY WENT AND BOUGHT A BRAND NEW BATTERY. ONLY AFTER A FEW DAYS THE BATTERY WAS DEAD AGAIN. ON A BRAND NEW BATTERY IT WOULD NEED TO BE DROVE EVERYDAY TO KEEP A CHARGE. IT'S TO THE POINT WHERE I WILL HAVE TO JUMP IT TO DRIVE IT AND THEN IT WONT EVEN KEEP A CHARGE FOR A HOUR. BRAND NEW BATTERY. NOTHING WRONG WITH THE ALTERNATOR. NO LIGHTS , ETC. BEING LEFT ON. NOT SURE WHAT TO DO WITH IT. NEED MY CAR.

STABILITY TRACK WARNING LIGHT KEEPS COMING ON I WAS TOLD BY MY MECHANIC THAT IT COULD BE THE SENSOR SO I HAD IT REPLACED WITH A FACTORY BRAND GMC SENSOR AND I'M STILL HAVING THE SAME PROBLEM. ALSO MY PASSENGER SIDE AIR BAG KEEPS SAYING IT NEEDS TO BE SERVICED BUT IT'S NEVER BEEN DEPLOYED AND NO ONE HAS AN ANSWER FOR WHY THIS WARNING KEEPS COMING UP THE STABILITY TRACK WARNING COMES ON AS I'M DRIVING EVERY TIME AFTER ABOUT 10 TO 15 MINUTES AND THE PASSENGER SIDE AIR BAG WARNING COMES ON AS SOON AS I START THE VEHICLE ENGINE. AND ALSO I HAVE A PROBLEM WITH CODE P0700 IT KEEPS TURNING ON MY CHECK ENGINE LIGHT AND I HAD IT FIXED BUT IT STILL KEEPS TURNING ON . RATTLING NOISE IN IDLE
