Hid headlights flicker/shake when driving over any size bump, or when you close the vehicle door.
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 received a recall notice may 2019 from maryann l. Combs, vice president global vehicle safety. The local dealership said parts were not available at that time. A few months later, still not available and today, february 25,2020 they are still not available and it seems they may never be available to vehicles in the "southern" states. My truck travels to mn, mt, nd on a regular basis and the problem in question needs to be fixed to keep the engine warm at below zero temperatures. The federal safety agency campaign id number is 19v328 and recall number was n182206311. Per the letter from ms. Combs use of the current engine block heater cable could result in an engine fire.
The first issue is a bluetooth issue. The phone volume goes silent when I get in my vehicle. If I connect to car play, it works. I have missed important calls due to this issue. This started in july of 2019 and its not fixed yet. Gm says it apple. Apple says its gm I do not care just fix it. Second see below images. You know the issue. This happened to me 3 times. It started 12-05-2019. Then again 12-26-19 . Serviced . 1-4-2020 again. 1-18 20 again and to shop until 1-23-2020. This took a lot of my time talking with my dealer. 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 .
Engine light keeps coming on take it to the dealer I guess they reset it and now this is the 3rd time it's now back on, back up camera goes out from time to time,
