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".
