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 (aœOil Pressure Low Turn Vehicle Offa), 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.
