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.

| Jan 2022 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Jan 2022 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Jan 2022 | ENGINE | 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). | Crash: No Fire: No | Unknown |

| Jan 2022 | POWER TRAIN,VEHICLE SPEED CONTROL | Transmission jerks, slams, forces a feeling of being rear-ended, delayed acceleration with sudden engagement causing uncontrolled acceleration. I've had it looked at every time I've taken it into the dealership for regular maintenance. They haven't been able to reproduce it as it only happens once, first time after not driving it for a while. No warning lamps or messages ever appear. | Crash: No Fire: No | Unknown |
| Jan 2022 | ENGINE | Every time I start the engine I get loud ticking noises. This is Lifter noise! I took it into the Dealership and they said the noise was normal. GM is known for having this Lifter problem in the heads. This can destroy my engine, causing premature wear on the lifters themselves. | Crash: No Fire: No | Unknown |

| Nov 2021 | ELECTRICAL SYSTEM,SERVICE BRAKES,ENGINE | While driving on a two lane road I proceeded to pass a slow moving vehicle, after accelerating from 45 MPH to 60 MPH my Check Engine light, Service Electronic Stability Control (ESC) and Service Electronic Brake System lights illuminated on my display. My RPMs increased before shifting gears and I noticed a significant loss in power. Thankfully there was not an accident when the incident occurred; however, if an oncoming vehicle or bad weather it could have been a different outcome. I took my vehicle to a GMC dealer to diagnose the issue where I found out my lifters for my valves are bad and my fourth cylinder is inoperable along with a bad CAM. A new vehicle at 65K miles on it should not be having mechanical issues that can pose a danger while driving, putting others and my safety at risk. GM needs to reevaluate the products and materials their using to build engines to ensure there are no flaws starting with the valve lifters. | Crash: No Fire: No | Unknown |
