Sunroof won't open, every time I try to open the sunroof it makes a loud popping sound. When I try to tilt the roof one side goes up and the other side stays flat.

With my vehicle stationary and shifter in the park position, I turn my car off and the vehicle turns off but the instrument cluster says "action required - shift to park". this message also does not allow the day time running lights to turn off and if the lights don't turn off the battery drains if parked for long stretches. I have to turn the car on/off several times before it engages and the message disappears.
Vehicle does not acknowledge that you are in park and will not turn the vehicle off completely. The engine shuts off, but lights and everything else stays on. If you exit the vehicle it beeps and the horn honks.

The vehicle has had ongoing issues since it was purchased in June of 2017. The 'shift to park' problem had to be fixed twice, the emergency braking system engages itself for no apparent reason which has almost caused several accidents, the horn does not work when needed in emergency situations, the headlights are so dim it's dangerous, the battery has drained and left my wife stranded 4 times, and the vehicle has a very rough idle and it almost stalls out. I attempted to work with GM to have them take the car back early (lease) and the request was recently denied. This is my 3rd Acadia and it by far is the most dangerous car I have ever driven. I am now reading about a fuel pump problem that could cause the vehicle to catch on fire, a driveshaft that may separate while driving, and a faulty braking system that could cause the vehicle to lose all braking capability. I do not feel safe having my family in this car and I am requesting your assistance to help me work with GM on a resolution. I entered the date that the vehicle first started to have issues, there have been over 20 incidents over a 2.5 year period causing a safety issue or leaving my wife and children stranded.
When I put my vehicle in park and turn it off, my shift to park message comes across and I have to turn my vehicle back on and move the gear from park to something else and back to park. Sometimes this has to be done a few times before it will completely turn off.
The vehicle states to 'shift to park' but the vehicle is in park already. The vehicle will not turn off and keeps the battery running. I must start up the car and shift it to drive, then pack to park multiple times before the car recognizes it is in park. This happens every time, but the amount of time it takes to turn on and off to reach 'park' is random.
"shift to park" alert appears when car is in "park" and attempting to shut engine off. Electrical system stays on with bell chiming until I can restart car and re-shift again into "park". this may have to be done multiple times before alert no longer appears. Does not happen every time when attempting to shut off engine, but when it does usually requires multiple restarting/re-shifting to get alert turned off.
When I shift the car to park and turn it off, I get a warning on the dash that instructs me to "shift to park" even though I already have. The vehicle will not turn off, and as a result I have to turn the car on and off shifting repeatedly up to 20 times to finally get the car to recognize it's in park. The vehicle is totally unsafe as it will not stay in park!
When I put my car in park I get a warning that says my car is not in park action required. The vehicle bell continues to ding and will not allow me to lock the car. My fear is getting out the vehicle and it starting to roll not knowing if the vehicle is actually in park. This is very scary not knowing if it is safe to get out of the vehicle.
I get a 'shift to park' notification when I put my car in park and try to turn it off. I'm confident my car is in park as it doesn't move when I release the brake, I have to restart the car, put it in drive or reverse, then shift into park again. Sometimes I have to do this 5 times before I'm able to turn off my car.
When the car is intentionally stopped and shifted into park, the dashboard shows a warning that the car is not in park. It requires moving the gear shift in and out of drive until the electronics recognize the car is in park. Until then, all the car electronics remain active. When the door is opened an alarm sounds because the electronics thinks the car is not in park. The GMC dealership is aware of the problem but claims the parts needed to fix it are unavailable. This first happened over a year ago, but the dealership couldn't recreate the problem. It has started happening again, and the dealership has recognized the problem, but claims the parts are unavailable.
After 2 years of ownership of a new GMC Acadia my SUV would not shut off once I parked my car. It would not be able to detect that I shifted into park after arriving at my destination. All the electronics would continue to run. I would have have to stay in the car and play with the shifter until the computer finally read that it was in park. After taking the car to the dealership the SUV was fixed with an new part that seems to have resolved the problem for now but as far as I am aware GMC is still doesn't know why the problem is being caused so I am waiting to see if it happens again. After getting it fixed now my vehicle gives me another warning every time my "auto engine off" is activated at when I come to a stop. Now I continuously get "stebilititrc" warning every time I stop. They fixed one problem and now I have another. It is my family car so I just want to make sure it is safe but GMC doesn't seem to know whats wrong or how to fix it even though they are aware of many Acadias having the same problem.
"shift to park" issue as described by others. GM dealer says it needs to replace a $20 harness + labor of over $200. "service parking brake" issue that randomly presented itself one day. I was unable to use the parking brake. GM dealer had to "upgrade" my ebcm for a whopping $200. How does GM think the consumer should have to pay for this. They have a monopoly because they are the only ones that can fix this!
When putting the vehicle into park, an error is displayed stating to shift the vehicle into park, even though the shifter is in P. in order to get this message to go away, I have to move the shifter up and down multiple times. Could take up to 20 min to get the error to go away. I can not leave the vehicle until the error is off because the lights stay on and will drain the battery. I also notice that the vehicle rolls a little more after multiple attempts to get error message off. This is concerning that it may not realize its in park and roll into another vehicle causing damage to both or roll away. I took to my dealer and was told this is a 'known' issue and is not covered under warranty, nor is there a recall. I just paid out of pocket for new tires because GM knew the tires placed were 'wearing' too soon based on mileage. Now, I am being told I will have to pay about $600 to get this fixed. GM knows of issues and not fixing them is wrong. This is not a new issue, has been listed as complaints for the past year, yet GM has done nothing to fix and continue to make the vehicle with the same issues. Frustrating that I have to spend the money to fix an issue they know about! this needs pushed back to GM to hold them accountable and make this right. The shifter issue should be a recall and fixed.
When shifting the vehicle to park and then shutting off the engine, I get an error message 'action required- shift to park'. the vehicle is already in park! I've had to jiggle the shifter, press the brake while jiggling the shifter, restart the vehicle put in reverse, then back in park, and jiggle some more. The radio and lights (both interior & exterior) will not power off and the door chimes nonstop. This happens randomly and it has been a little over a month since the last incident which occurred two days after I had to replace the battery because I missed the error message heading in to work. The last 2 days my husband has disconnected the battery because nothing will work to power off radio & lights. I've had to replace the battery twice now in a new vehicle leased in 2016. The first time was due to brake recall, my vehicle being the only 2017 GMC Acadia denali effected by that recall. The brake lights would remain on because the brake was basically sticking, draining the battery. That issue also disabled the cruise control as that feature is unavailable when breaking! this vehicle also had repair to wiring in driver side door due to water getting into the door frame from outside and corroding wires causing detection issues with the key fob. I could not unlock my doors without removing the key to manually unlock. While in the car wash, the vehicle lost connection with my key and the driver's seat moved all the way back as it would for easy exit which I had disabled. Message stating key not detected wouldi was told a needed a new battery in my fob, dealership replaced, called & said everything was working as it should. They ran the vehicle through the car wash before I arrived to pick up the car. When I tried to unlock the doors, the vehicle would not recognize the fob. Thank goodness the service rep was there to witness the malfunction.
Upon shifting the car to park and shutting off the engine, the console says, "shift to park". the car appears to roll some. I have not been on an incline to see if it is truly in park or not. It will not allow the electronics to shut off and will not let you lock the car so the car cannot be left when this happens. It has been happening intermittently and today I had to shut off and start the car and drive it 10-15 times before it would recognize it was actually in park.
Shifter keeps locking. Happened 4 times where shifter had gotten stuck in shift and unable to control car. Gear assembly has been replaced 4 times and nothing is working.
