Lost ALL oil pressure while casually driving 35mph. Safety issue, had to stop on side of busy highway. Truck warned me to turn off engine.

I am unsure why this organization has not made GM fix their lifter issues for their v8 engines. it is very common and has been around since the early 2000's especially with the 5.3-liter engine. my engine just had lifter failure at a little over 80,000 miles. this repair can cost up to 4000 to 12000 to fix depending on how bad the failure is. There are class action lawsuits on this issue. It's time to make GM pay up for customer losses. I am 5000 over my extended warranty, can't get a loaner from the dealership, haven't had my truck for almost over a month, spent 900 in car rentals so far. Again, this is a known problem, it needs to be addressed and fixed once for all. * Summary* Lifter failure Happened on the highway, lost almost complete power to my drive train abruptly. putting my safety and others safety at risk This is a very known and common problem with the dealerships, even the tow truck driver said must be your lifters before it was even at the deal, said he picks up 2-3 of these trucks a week with the issue. The component is at the dealership. diagnosed as failed lifters, still waiting for them to inspect the internal parts of the engine to see if it destroyed the internals with the failure. Warning lights came on at failure, and no symptoms beforehand.

Valve lifter broke cause misfire and engine slowdown. Truck towed back home, no longer useable, dealer stated vehicle off warranty GM has no recall. This is a known issue, with many incidents which has led to a class action lawsuit, that I am planning to join.

The contact owns a 2019 Silverado 1500. The contact stated that while her husband was driving 25 MPH, he observed a burning oil odor coming from the front of the vehicle. An unknown warning light illuminated with a message to turn off the vehicle. The vehicle was turned off and was towed to the residence. On another occasion, while driving approximately 55 MPH, the oil pressure warning light illuminated. The vehicle was turned off and towed to a dealer where it was diagnosed that the oil pressure lines had ruptured, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was 74,350.

Driving at normal speed, normal weather, and normal highway conditions my 2019 Chevy silverado 1500 suddenly, without any prior warning, became undrivable due to "No Oil Pressure". I had to pull over on the side of the highway where it stayed until the vehicle could be towed to a local auto mechanic. The mechanic informed me that the issue was due to an Engine Oil Cooler Line rupture; the same issue that's plaguing many other vehicles of my age and make. There is a recall: N212326940-01 as evidence. I don't understand why this recall hasn't been issued to others outside of Canada and Alaska, especially when this problem is happening at frequencies to cause a shortage of replacement parts in other parts of the U.S..

Engine cooler line is leaky. if I continue to operate the vehicle with low oil pressure, there may be a loss of propulsion. An engine operating with low oil pressure may also be prone to failure. In 2021, a TSB was issued to repair this problem, but it no longer is active.

The truck has lifter failure leaving the Engine in Operatable at best you and you kids are stranded in 0% wether or broken down in the road. The other outcome is the Engine Explodes like a bomb when the internals let go from the failure. Lucky I was just left in the cold where I could have frozen to death. This happened at 70k miles but is happening to all the 19+ trucks with 5.3-6.2 the other problem is a transmission shudder making you barely able to keep control of the vehicle. You have had so many complaints here there have been several class action lawsuits yet nothing has been done why is Gm not held accountable?

I was driving my 2019 Chevy Silverado and the low oil pressure light came on. I pulled over to find that my truck was leaking oil. I called a tow truck and had the tow truck take me to location that I bought the truck (25 miles away). While waiting for the tow truck I did research about what could be happening. While doing my research I found this recall by Chevy: [XXX] My truck was looked at and I was called the next day and informed that the issue was "oil cooler line crimps coming apart and leaking". To my dismay I was informed that my VIN was not part of this recall. I find this to be either very ironic or the recall needs to be expanded to include additional 2019 Chevy Silverado's. I have an email from the service manager; Dereck West, at Victory Chevy Milan Michigan, stating that the diagnosis was as follows: "inspected to find oil cooler line crimps coming apart and leaking. replaced oil cooler line assembly". Again, this seems to match the recall perfectly. I was advised by Chevy to file a complaint and retain all records related to this incident. I have tried contacting GM for additional support. I have been unsuccessful with getting any responses from GM customer support. Upon additional research I found many forums that describe the exact same issue that I have described above. Customers having to pay for an issue that matches identically to a recall because their VIN is not part of the recall. It is my opinion that this recall should be expanded to include additional VIN's for 2019 Chevy Silverado's. I am more than willing to provide any additional information that might be needed. I appreciate your time in advance and look forward to hearing from you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I started vehicle. Everything seemed fine. Drove 2 blocks and all eletricals started acting up. Lights flashing all warning lights went off. Service brakes, Service parking brake, service ECM, etc. Motor started to bog down and major knocking from engine. Took to GMC dealership. They found issues with lifters and had to replace all lifters and camshaft. Also replaced faulty brake sensor. Get truck back and oil cooler hose or line came off and was leaking oil. 1 week after repairs. Take back to dealership for repairs. 2 weeks later went to start truck all electronics went haywire, lights flashing, all warning lights start going off again. Truck will not start. Let sit for 15 mins. Try starting and no electrical power at all. Truck will not shift out of park. Major issue. Sounds to be a common issue with 2019 Trail Boss. Only has 40,000 miles.

Oil cooling line failure at crimp joint. If oil line were to come apart all the oil would come out under the vehicle which could cause a vehicle to go out of control or vehicle surrounding this vehicle to go out of contoll. Plus it would destroy the engine. Independent service center confirmed the issue. Other than myself and the independent shop inspected it. The car was at the dealer and said it was normal oil consumption. They did not due their due diligence to determine the cause of the oil loss. The warning comes on the information screen saying to add oil. There was a Technical Service Bullentin (n212326940) issued by GM that expired on July 31, 2023 to address this specific issue with a NHTSA ID 10200186. The problem is GM states that my VIN number was not part of this correction. The TSB only pertained to a small specific group. In researching this it is a wide spread issue of failures for this specific part. My truck was at the dealer the summer of 2022 but because the cooling line leakage is at the front of the vehicle dripping right under the front bumper, almost 20 inches from the motor it never dawned on me that it was part of an oil loss issue from the cooling line. At the time it was in it was still under the 3 year, 36 month warranty. Which meant it would have been covered.

My truck recently started to leak oil onto my driveway so I took it to a local dealership to get it looked at. The service engineers diagnosed the problem as the Engine Oil Cooler line is detaching from the crimp causing oil to leak out. They also told me that there was a recall, see PDF attached, (#N212329640-01) that is associated with this problem. However, it only applies to my vehicle if it was manufactured in Canada and Alaska. My vehicle, I was told, was manufactured in Mexico. I brought it to the dealership and they told me this doesn't apply to my vehicles simply because of where my vehicle was manufactured. This is troubling information as the SAME issue that was part of a national recall is the SAME problem that is happening with my truck and could cause a major safety risk while driving, yet it is not part of the recall based off where it was manufactured. Specifically, the vehicle could be involved with "loss of propulsion" as stated in the original recall. This is too coincidental of an occurrence to simply ignore it which is why I wanted to file a complaint.

When I shift the vehicle to -??Park-?? and shut off the engine, a -??Shift to Park-?? message comes on the dash and the electric components won-??t turn off and the vehicle chimes until it will randomly stop. Sometimes it does not stop and will drain the battery completely. This happened once at a wedding venue in the middle of nowhere and I was left stranded. No matter how many times I restart the vehicle and shift to different gears, the message continuously comes up and only way to avoid battery draining is to disconnect it, which is a major inconvenience.

One of the oil cooler lines on this truck is leaking oil from the crimped area where the rubber hose connects to the metal part. The GM Authority website says the dealer should fix this at no cost to the vehicle owner be because it is a GM issue on 2019 Chevrolet Silverados and 2019 GN Sierras. I called them and the lady looked up my VIN and said my truck isn-??t included in this issue, but clearly, it is. The description of the issue on their website is the exact description of my truck and the issue of the leaking oil cooler line in the crimped area.

Engine failure at 86370 miles while driving down the highway. Towed to Sullivan Tire, mechanic found 2 bad cylinders and the lifters had destroyed the cam, requiring a total engine replacement. This mechanical failure of the engine was sudden and unexpected, placing myself, my children, and other drivers at risk of injury on a very busy highway (MA-24). Discussing this with the mechanic (Sullivan Tire), this malfunction has been confirmed by a GMC certified dealer and service shop (McLaughlin Chevrolet) that there are several other Chevrolet/GMC vehicles that GMC technicians and third-party technicians that are reporting have had the same mechanical failure in the engine. I am unaware if this has been inspected by the manufacturer. It has only been inspected by third-party technicians at Sullivan Tire in Bridgewater, MA. There were no warning lamps, messages, or other symptoms of the problem prior to the failure.
