After heavy rain or a carwash, the door locks and lift gate don't work from key fob. And the vehicle says no remote detected and has trouble starting. After a day or two they start working again. It caused U0422 (invalid data received from body control module). On forums it says it can be water leaking into the vehicle and shorting out the BMC from either the HVAC drain or a weatherstrip somewhere. Now my rear passenger door locks don't work at all. Dealer wants to replace the actuators but can't find the root cause of the problem. Issue has been going on for over a year now.

Unknown 3rd brake light leaking water inside. Health Concern due to mold.
I have many problems with this vehicle, numerous times. Inaccurate Fuel Gauge Reading- It has resulted in my vehicle running out of fuel and stalling, while on road. I have 4 children who are at risk of danger while in vehicle.The fuel warning light has illuminated when the gauge needle says I still have more than plenty of amount (a quarter of a tank or more at times. It differs). It was diagnosed with an electrical and fuel system failure. Electrical shorts and problems- Having electrical shorts on and off. Check engine light comes on/off Vehicle randomly failed to start. My vehicle was difficult to start and would require several attempts before starting. Power lock/unlock key fob doesn't work, replaced battery multiple times.windows and sunroof power windows do no work. Radio and dash turn off and restart. Check airbag light has been coming on and off. Power Train intermittently, the transmission shifts with a loud thump, at various speeds.

Other/ water leak- Found water in all of my tail light assemblies, headlight assemblies, sunroof and windows leaking.

This vehicle has a severe water leak after rain event from body. Leaks into electrical, floor boards, roof. Dealership not able to locate water leak location. Have been working on it going on a month. We recently purchased the vehicle used.
There is a water leak problem with the Acadia ! My car had a dead battery and when it was time to change the compartment was full of water I also get water under steering wheel.
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.
The issue started with my back hatch opening on its own at random times. Found out this was caused by water entering the lift switch. That problem lead to the battery eventually going bad and then the headlights being blown due the bad battery. Not sure how water got in the back hatch ruining the sensor but this is costing me about $1000 to fix.
