GM Releases Fix For 2019 Chevy Silverado, GMC Sierra Over Oil Cooler Lines
Sponsored Links
General Motors has started a Customer Satisfaction Program to address an issue related to the oil cooler lines in certain examples of the 2019 Chevy Silverado 1500 and GMC Sierra 1500.
The problem: in affected vehicles, the engine oil cooler lines may leak and detach from the crimp joints. Exposure to cold temperatures may also aggravate this condition. If the engine oil cooler lines leak, there may be an oil leak on the ground and if the lines detach entirely while the vehicle is in motion, there will be an immediate decrease in oil pressure. This will also coincide with a low oil pressure warning on the driver information display and a warning chime.
The hazards: if the user continues 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.
The fix: dealers are instructed to replace the engine oil cooler lines, oil filter and coolant. These repairs will be performed at no cost to the vehicle owner.
Affected components: engine oil cooler lines.
Affected vehicles:
Number of affected vehicles: GM did not say how many vehicles are involved in this customer satisfaction program.
Next steps: owners of affected Chevy Silverado or GMC Sierra trucks will most likely be instructed to make an appointment with their dealership to have the engine oil cooler lines inspected and replaced. Owners with additional questions or concerns can also reach out to Chevy or GMC directly using the contact information included below.

I had my hose blow and all the oil dumped back in the early summer…. I plan on buying this truck, but not unless I know the new improvement was done to prevent it from happening again.
What are the chances this was improved when fixed in June of last year?
This is a cold weather issue only so go get it either fixed and updated by a dealer or use some wrap around insulation around the affected lines This isn’t rocket science.I live in Arizona and no issues,2019 Trail Boss.
Late 2018 Silverdo with 5.3 and 8 speed. I was just diagnosed with the problem during a dealer oil change. Apparently they are looking for this issue. there is a recall, but only on Alaska and Canada Silverado’s. They state is it cold weather that causes it. Well I live in the Northwest and we get the same weather as British Columbia. So if I live 2 hours north of me across the border, I get the work done for free, but not where I am. Come on GM. You Screwed Up. Fix it.
The Michigan dealer told me that my lines were leaking and needed replacing on my 2019 Silverado Trail Boss but that this “Customer Satisfaction Program” was only available for Alaska and Canada vehicles. I’d have to pay the $1000.00 bill. I called the Chevrolet Customer Service Number and got the run around. Eventually I spoke with a lady whose kids were crying in the background. She told me that they couldn’t help me. Seems like if it’s a faulty part that would be fixed no matter where the truck is located. So much for a “Customer Service Program”….
Update to reply April 27th 2022. Finally got my 2019 Texas edition truck out of the shop. Instead of replacing the seized engine, they replaced the crank shaft. It lasted one week; engine shut down on the interstate and this time lost not only all the oil, but the coolant as well. Its been in the shop now for over a week and they haven’t had time to look at it. If I wanted a paper weight; I’d have picked something smaller.
