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. Vehicle starts shaking and jerking while shifting gears and going different speeds. My vehicle slows down, power reduce engine and steering difficult at times. Other/ water leak- Found water in all of my tail light assemblies, headlight assemblies, sunroof and windows leaking. There is no proper seal or has worn off, causing leaks in and repairs for many replacements, which are expensive temp fixes with no permanent solution. Causes accidents by not having necessary working equipment for driving conditions. Other:Hood doesn't latch and stay open so difficult to even check fluids properly alone. Multiple dealers have inspected problems, and needs to be fixed. There are recalls out for many of these problems and my vehicle needs to be on the list for serious safety issues.

I have 2 concerns and issues with my vehicle. 1st is the rear turn signal bulb and housing, I have read forums and researched the issue and many others have had the same issues and concerns, water is getting into the housing and is causing the bulb to blow and can possibly be causing fire/electrical with the wiring. 2nd is the front headlights the plastic round covering that's in surrounding the the glass that the light sits behind is melting and is causing visibility issues as well as potential fire. I can imagine why the plastic would be installed so close to a glass covering that holds heat. I really think that GMC needs to evaluate these concerns not only for safety but also the expense of the turn signal bulb that has been designed and cost over $100 because it couldn't be a simple bulb like most others. Also I have been informed of a recall of the airbag and can't get it fixed because the dealerships haven't been sent the part! I would like to be notified that someone has aknowledged my concern. Thanks

I noticed headlights not working low or high beam. LED lights around head lights worked and fog lights but no headlights. I normally keep it on auto, but I tried all positions and none of them worked.

Head lights quit working. I had two children in the car with me and it was night time, and I could’ve collided with another car. This just happened tonight, so I have not taken it to the dealer yet or a certified mechanic. There were no warnings of any kind before this happened.

My left rear turn signal is not working. It is GM part number 13582912. I have checked with several GM dealers who have. Confirmed there are none available. Just for the sake of it, 3 dealers have it on order but have no confirmed delivery date. Some parts stores say it’s is discontinued. There are no other aftermarket parts to substitute. This is a significant safety issue the GM needs to correct.

Tail lights/brakes light/blinkers The light kit cover seals break allowing water into the light kit. Water collects and shorts out the bulbs causing a dangerous hazard when rear lights fail to work in the proper manner. I have called to several places and am being told, yes, GMC has a defect on their rear tail lights. Seals were not done very well and supply cannot keep up with demand. The lights are over 300 each which is absolutely ridiculous. A part that is necessary to keep one safe and be able to signal to other drivers should not be this expensive when the manufacturer did not build a good product.

Service side blind detection started going off then the side blind detection stopped working completely. Now the entire electrical system is not working correctly and was told the side blind detection monitors can cause the entire electrical system to malfunction.

Car shut off while driving. All electrical went out. Doors all locked while inside, key stuck in ignition. Started with side detection warning and within a few days car completely shut off while driving! Huge safety issue! Will not restart and still can't get key out of the ignition. Battery is fully charged but no power. Completely dead. There is a known recall on 2014 gmc acadias for electronic module failure but not our specific vehicle though this seems to be the exact cause of our problems. Gmc said they could not help?!
