I have had the 2019 Sierra 1500 AT4 with 6.2 liter engine in the shop (8) times since purchasing it in late Aug 2019 for multiple issues, including the issues relating to the brake software recall. This resulted in me rolling through a stop sign without any brakes. Luckily there was no oncoming traffic. As an engineer, I have no confidence that the issue has been fixed long term by GM. My family will no longer ride in the truck with me. As a result, I have retained an attorney for the purpose of filing suit against GM for selling me an unsafe lemon. Even further concerning is the fact that on (2) occasions the parking brake has engaged while driving down the highway at 55 mph. One time while in 4WD in snow, and the other time while in 2wd on dry pavement. The first time there was a diagnostic code associated with the parking brake engaging randomly. The second time, there was no diagnostic code present. The first issue with braking began 11/14/2019, and the most recent issue occurred on 2/2/2020 even after all recall "fixes" have been applied.

After my recall was fixed my truck locked into 4 wheel drive and I lost control of all my safety features. My lights would not work. They fixed what they said was a glitch in the recall and 3 weeks later my engine light came on again and my brake system started to show lights. They recalibrated the brake system recall again.

Dear NHTSA, I recently leased a 2019 GMC Sierra pickup truck. This truck is currently in the shop for the 6th time, and neither GM or the local dealership can seem to fix anything on this truck. Most recently, as yesterday I had my car in for the braking system. The dealership called me and said my truck was fixed. As I turned my truck on, the brake system light came on. I was told by the dealership to just drive it and it will go away. I do not feel this is a good/safe practice and GM is not helping me to get out of this unsafe truck.

On April 21st a pressurized line leading from the engine to the engine cooler failed and the engine suffered rapid oil loss leading to engine failure. This appears to be a frequent issue with 2019 Sierra and Silverado (the new body style): Https://www.GM-trucks.com/forums/topic/222403-2019-Silverado-trailboss-53L-engine-oil-cooler-line-failure/ the truck was moving at approximately 35mph on a straight surface street at the time of failure. Mileage was only 5,500 miles. Other impacted owners seem to believe it is a failure of a poorly designed crimp connector. It's been 15 days since the incident and my vehicle isn't repaired yet. Other owners report waiting close to 30 days for GM to decide how to proceed.

While driving down road, sudden message of "no oil pressure, turn off engine immediately". was able to pull over with no power (luckily it was safe to do so at the time). Left a large puddle of oil underneath the front of the vehicle. Also, left large cloud of smoke from oil splashing on hot components underneath vehicle (exhaust, etc...) behind me. Vehicle was undriveable and had to be towed. Large oil leak was the result of a burst oil cooler line. Dealer did not show me the failed part. Unable to confirm nature of "burst".
