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 headlights stopped working while I was driving on a highway. I pulled off the road & the drl LED lights around the headlights were still on, but the headlights were not. I tried turning the lights off/on, tried turning the vehicle off/on. My husband checked the fuses, relay, & sensors, as well as changed both bulbs and they still will not work. It was dark while I was driving, which posed a dangerous situation. Upon researching online, there seems to be other people who have had the same problem.

Headlight illumination is limited and prevents driver's ability to see upcoming road conditions, curves, elevation, animals or humans in the road and hazards. Without turning on the high beams. There is a distinct cut off of light at the top of the area illuminated that is not commonly seen in other vehicles and this limits how far ahead you are able to see.

I purchased this vehicle 2 months ago and have had to separate change the headlights on it twice already. There is a common issue with the electrical system that makes the headlights go completely out or dim while driving or in idle at times.
