While truck was parked (engine was not running at all), I used the key fab remote to unlock the truck and then open the tailgate. at this time, the tailgate slammed open (very forcefully and quickly) and hit my son in the chest. this has also happened while the truck was running and in park. at that time, I (the driver) pushed the button on the center dash to open the tailgate so that my young son could put his baseball gear in the bed of the truck. again, the tailgate opened very quickly and abruptly, slammed open, and the heavy tailgate hit him in his body. the tailgate IS supposed to open slowly and gradually, not slam open. thankfully, my son was not seriously injured. the remote control, slow opening tailgate was one of the selling features of the truck, and now the tailgate IS dangerous to use at all, especially when children are around.

I understand I am one of many, but I didn't spend over $66,000 to buy, lease this vehicle to have to waste my time. This cost me time, money and honestly every time I start the truck I wonder if it will reappear. I received 2 calls fro representatives, gianna and michelle. I called back 3 times, left voicemail and have heard nothing. at this point, I am requesting for gm to end my lease and I give you this truck back .

After starting my vehicle remotely using on-star, my brakes stopped functioning properly... After remote starting the vehicle using my on-star app, we entered it, depressed the brake and pressed the start button. At that time I received multiple error messages, stating "brake system failure, 62 mph top speed" "service esc" " steering assist IS reduced drive with care." I restarted the vehicle a number of times and the error messages went away. I then began to drive home and after about 2 miles the error messages all came back and my brakes stopped functioning. I was able to use the full force of my body on the brakes to get the vehicle to come to a stop from around 30 mph in my neighborhood. Had I been on the highway or on the main street I had just been on I likely would not have been able to stop without hitting another vehicle or object.

After using app to start the vehicle, I sat in the driver seat depressed the brake and pushed the start button. Immediately a warning popped up saying esc needed service, service trailer brake, speed limited to 62mph. Additional lights illuminated including brake, traction control, ABS, and cel. Since the dash indicated that the speed was reduced I thought it would be safe to drive, however at the first turn I realized my brakes were nearly gone and I went through the intersection. The brakes appeared to have lost the boost and were extremely hard to depress making it difficult to stop the vehicle. I limped the truck home and notified the dealer. The next day I tried starting the truck and the brakes returned with no dash messages although the cel was still illuminated. There IS a recall for a similar issue but it looks like my vin IS not apart of it.

Brake system failure 62 mph top speed 5. Check engine light. Vehicle was stationary and I did not drive afterwards.

When I pick the truck up, I noticed the lane keep assist, lane departure warning, intellibeam headlight, forward collision alert, and other functions associated with the window mounted camera system were inoperable. I have an appointment already scheduled for that and will add this for the dealer to investigate. Truck was taken to dealer for recall on 1/7/2020 and I got it back on 1/18/2020 because of the window replacement.

Vehicle has faulty transmission system that at shakes during use of the vehicle at all speeds. the vehicle also experiences "hard shifts" at low speed to the point that the vehicle rear tire "chirp" with such force that it feels like you've been hit from the rear by another vehicle.
- Exterior lighting
The headlights flicker violently when driving at any speed. According to the dealer the issue IS normal. It IS very distracting to drive at night and likely distracting on coming traffic. The truck now has 13K miles and has gotten worse to the point we don't drive it at night.
