My 6 year old son and I were coming down the road and came up on 2 deer and I was coming up on a sharp curve and when I hit my brakes my steering wheel LOCKED up completely and the steering wheel is so bent where I tried my best to control it but I failed and we hit a tree head on. Broke my nose and my sons leg broke in between the back seat air bag and door air bag

I have owned this vehicle almost 6 years, 40,000 when purchased used. Since purchase, we have had multiple issues with the trailer brake system randomly going off, dinging non stop, we had the problem serviced under our warranty and is now going off again. We do not tow but a few times every summer which is our jet skis however. This has happened multiple times prior to us using our warranty, the garage says they fix it but it keeps happening. I am very frustrated that I can't drive my vehicle down the road without a continues dinging. I looked up what "trailer brake system" means and found that it can be very dangerous and GMC's are known to have this problem, it is suggested that I lodge a complaint in hopes of getting this problem resolved from the manufacturer before a driver becomes seriously injured when the braking system decides to fail. I have read complaint after complaint. …

My 5 children and I experience a traumatic experience in afternoon traffic as my 2015 GMC Yukon failed to pick up speed while waiting to make a left turn at a traffic light. The vehicle - no matter how hard I pressed on the gas didn't accelerate immediately which almost cost an accident. The vehicle rode smoothly for a few minutes then out of nowhere - it started jerking and stuttering bad for 15 seconds or so then would go back to riding smooth. When pressing the brakes - it seems to "lock" to a certain extent, so I have to press really hard on the brake to slow down/stop the vehicle sometimes makes a strange noise when doing so. I took the vehicle to be accessed by a service center in my area - it was at that time that I was told that my vehicle issues are known common GMC issues in these vehicles & more unfortunately. …

While I was in line at the gas station to get gas, I moved up because the car I front of me had done so. After moving up a bit, I pressed my feet on the brake but the pedal was very stiff and the breaks did not hardly engage. I almost ran into the vehicle in front of me. This was very scary. So I called for a tow truck to pick me up but after a while they didn't show. I started my car up to see if the the brakes engaged and they did. So I slowly and carefully drove myself to the GMC dealership in Southaven, MC which was 0.3 mile away from the gas station. The GMC dealership said that it was vacuum pump that was at fault and admitted it was a recall for this. But they said since my truck has already been serviced for this recall that I would have to pay to get it fixed. This is absolutely absurd. …

There is a recall on my 2015 GMC Yukon, that I am not the original owner of. The recall is for the brake booster and says that it expired. I have had the car checked by two different shops (both confirmed it was this), and one of them was the local GMC dealership by my house. I called to make an appointment for the recall to be fixed, to which they said they needed to order parts and it would take a few weeks. I dropped the car off three weeks later per their request for then another person to call me and say they won't fix it because it is expired. It is a safety matter that the breaks don't work occasionally.
