1) Wiring harness to the wireless charging pad on the center console that is wired through the door hinge. Shorts out when opening or closing center console. 2) Caused a fire that led to smoke and melted components inside center console hinge. Caused smoke and awful plastic burning smell while my kids and I were parked. I had just started the vehicle. My two kids and I had to jump and run from the vehicle. 3) No, but by many forums that dealers and mechanics are aware of this issue and charges you hundreds to fix it when it is MANUFACTURE ERROR. 4) This vehicle has been inspected many times. By all the other inspection laws Missouri has in place. How has it gotten passed many times with this known issue? 5)NO! This put mine and my kids life at risk. It is a known and wide issue yet no one takes this seriously. As it just affected me and my two children, I hope this is taken seriously. …
Consuming a lot of oil, makes a funny clicking noise sometimes when accelerations, had lil pieces of metal in my oil, Transmisson problems, 1 front headlight and all rear tail lights went out, trailer brake system would come on and go off now it won't stop dinging and makes a whole bunch of other lights come on (trailer brake system, park assist, low brake fluid, traction control, collision) dings some much I can't drive it. Called a gm shop near me and they told me it would cost a whole bunch for each diagnosis for every warning that came on.
Air intake stayed on after shutting vehicle off and locked. It seemed it was in auto start mode from the key fob. Now it is hesitating to go and struggling to switch gears. Local mechanic is unable to pinpoint issue. Will bring to GMC dealership next. The rear camera intermittently works. If you open and close it sometimes it will fix it. USB ports intermittently work. Both taillights had to be replaced due to intermittently going out. Both front heated seats only work on top.

The engine turns off when driving. This has happened at least 50 in the 2 years I've owned the vehicle. It has been serviced at Garland Shelton GMC in Temple, TX. The issue is not fixed. The battery and the negative cable have been replaced. When the engine dies none of the electrical works until I open the hood and wiggle the negative battery cable.
Driving at a normal speed around 30 mph when vehicle suddenly becomes hard to steer as if the power steering just cut out or off therefore making it extremely difficult to control the vehicle and felt like a rough ride while this is taking place.....Definitely sounds like a safety issue......DASH READING WARNING SERVICE PWWR STEERING
The problem initially started around August 19th when my daughter was driving the SUV. It started suddenly flashing multiple service problems ex trailer brake service, park assist service and stability track service. It started flashing them over and over every second and the engine would rev up then slow down which continued even after she was able to pull over and get it into park. It was terrifying for her. We had the vehicle towed to GMC. GMC felt the electrical problems were due to the fuse box so they replaced the entire fuse box and changed all the fuses. Last week, my daughter again was driving home on the highway and the vehicle started doing the same warning but also displayed several more warnings and the car was lurching forward and slowing down over and over again despite trying to maintain a safe speed. She was close to home and thankfully made it safely home. …
