Oil coolant line detached from the crimp. GM customer satisfaction program N212326940 is exactly what has happened and GM states it is not associated to my VIN so they can't (won't) do anything about it, even though the bulletin clearly indicates 2019 Silverado 1500 (new model). This occured as I was on the interstate. I pulled over as soon as the warning came up telling me to turn the vehicle off. I had to wait on the side of the interstate for several hours for a tow to a local mechanic shop. The mechanic diagnosed the issue and took photos and described the issue in writing. Prior to the incident there was no vehicle warning light that there was an issue, nor did I receive a letter warning of the issue. This catastrophic failure of the coolant line ejected oil, coating the undercarriage and passenger running board. The program bulletin states: Condition: Certain 2019 model year Chevrolet Silverado 1500 (New Model) and GMC Sierra 1500 (New Model) vehicles, may have a condition in which the engine oil cooler (EOC) lines may leak and detach from the crimp joints. Exposure to cold temperature may also aggravate this condition. If the EOC lines leak, there may be an oil leak on the ground and if the EOC lines detach while operating the vehicle, there will be an immediate decrease in oil pressure. This will coincide with a warning on the driver information center display (-??Oil Pressure Low Turn Vehicle Off-??), along with warning chimes. If the customer continues to operate the vehicle, a loss of propulsion is possible. Correction: Dealers are to replace the engine oil cooler lines, oil, oil filter and refill the coolant.

I was passing a line of vehicles when a semi started over into my lane. I hit the gas, to avoid being hit by the truck. When I did warning light on my vehicle appeared on the display. I lost speed and immediately heard a loud knocking from the engine. I was on an open 4 lane highway and knew there was a dealer close by. I drove to the dealership, I left the vehicle running so they could hear it. The service tech told me they had seen "several" vehicles in with the same problem with the 5.3L. I left the vehicle there and was given a loaner. They told me the lifter had gone bad when I sped up quickly, and the camshaft was damaged. Further research by me has discovered a lot of vehicles have this same issue due to the active fuel management system. I chose not to pay Chevrolet $7000 to fix the engine, and currently have it in a private shop being repaired. A less experienced driver may have slammed on the brakes or swerved and caused a major accident. My vehicle did slow down on its own, but I was able to keep control and safely maneuver to the right lane.

I was getting on the freeway and all of a sudden a lost power and heard a loud clunking noise. I drove as fast as I could to get in a safe area. Afterwards I had my vehicle towed to my mechanic. They said engine failure and possibly transmission failure. They found metal shavings in the oil. I had changed it myself a few weeks prior. I then took it to a gm dealer. I was just outside my powertrain warranty at about 70k miles. They said the same thing. 24k to repair. I had to junk the vehicle.

Hard shifting, shutter, jerk, hesitation feels like the motor is going to fall out. Haven't had the manufacturer look at it, but it's very annoying and embarrassing.

In 2024, I had the transmission replaced due it leaking transmission fluid. The transmission is sealed and there is no way to add fluid. This created an internal problem for the transmission. In January 2025, the engine made a loud pop noise and began performing horribly. My wife and I were on the interstate in a major city and surrounded by traffic. I drove it to the side of the interstate, immediately, and turned it off. I had to call someone to tow me back home(2 hours away) and my wife missed a very important doctor's appointment. Upon inspection, I found failed valve lifters, camshaft, pushrod and valve lifter tray. I managed to get everything replaced and the truck ran fine. March 2025, as I was driving on the highway, the truck stopped running. A message came on the dash screen saying, "Shift to Neutral and restart". I did and nothing happened. I had it towed to a shop. They told me it was a fuse block that was blown and the starter blew so they replaced them. It had struggled to start a couple of times and since I knew it had a new battery, a starter and fuse block made sense. I picked the truck up and in less than 24 hours, it happened again. It stopped running as I was driving and would not restart. The shop has checked GM tech forums and found where someone said to check if the motor would turn over manually. They have tried and failed. They, then, took the oil filter off and found metal shavings in the oil. Their diagnosis is that the engine bearing has seized and is causing the problems. My main issue is safety. My wife and I could have been seriously injured or killed and could have injured or killed someone else when the incident happened on the interstate. The same could've happened with just me in the vehicle or with our children. There were no warning lamps, messages or any symptoms whatsoever before January 2025 for the engine. The truck doesn't even have 100,000 miles on it and I have kept up all of the maintenance.
