The screen on radio is so bright in the cab when backing is blinding when backing up and dangerous. No way to turn down the brightness.

when I bought the vehicle in October2018, I have taken the vehicle back to the dealership multiple occasions and they refuse to fix this issue. The transmission shifts from first to second gear or second to first gear is clunky, jerks forward and shifts without warning. While sitting at a stoplight, the vehicle will sometimes lurch forward several inches without warning even with your foot on the brake. Furthermore when accelerating between first and second year it's sluggish and takes several seconds to shift from first to second the engine Revs high.

Hard shift on take off from 1st to 2nd gear and while driving around random hard erratic shifting. Feels like pickup is getting rear ended. Have take in to Gregg Lair in Amarillo TX and they have reset shift points to no avail. I talked to head service writer and he stated that GM had a problem with their transmission but did not have a remedy for them. He advised to drive for about 3,000 miles and we have and still have the issue. We have been back multiple times and Gregg Lair states that it is still in learn mode after over 10,00 miles. I am a mechanic by trade and in my opinion there is a design flaw with the transmission and/or they have the wrong transmission fluid for the design.

The 2019 GMC SIERRA I own shifts extremely hard from a stopped position or when changing from reverse to drive. The shift is so forceful, that it feels like I have been struck by another vehicle. The overall feeling is that the vehicle is not safe to drive and it is not a reliable mode of transportation. The delayed shift, vibration and jerk, makes this vehicle a hazard to drive, as the ability to predict the issue is impossible. There are no other warning lights, or messages prior to the error. Online forums show this to be a known issue.

My 2019 GMC Sierra was traveling on the highway at 70MPH. The oil cooler line detached, and the truck shut down telling me to get over now. There was oil everywhere. I am shocked it did not catch fire. there was also 7 quarts of oil on the highway I called the dealer, and they are well aware of this problem. They were sorry but there is nothing we can do for you. They told me they do 1-2 oil cooler lines a month. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
