While driving "No Oil pressure" alarm went off on my 2019 Chevrolet Silverado. I had to immediately pull off to the side of the road, upon inspection the Oil cooler line separated at the crimp joint. This is the exact failure mode as described in "N212326940 - Customer Satisfaction Engine Oil Cooler Lines Detaching from Crimp". I have my truck at a GM dealership and they said my VIN is not included on the TSB. I also contacted GM Customer Service and was told the same that my VIN was not effected by this issue. My failure is the same mode as the documented issue, it has to be related to part quality issue as described on N212326940. The GM dealership is charging me $2000 to replace the line.

I had the vehicle towed to a Chevrolet Dealership, they indicated that the Camshaft is broken, at least one lifter and rod is bad. It is less expensive to replace engine.

On 7/2/25, I was driving my 2019 Chevy Silverado on the highway and felt like there was a slight loss of power. I then noticed the Service parking brake, service ESC and the check engine light came on. I was going up a hill and had to move over to the far right lane and drive very slowly on the highway because of the engine problem. I was able to get off the highway without incident. I immediately took the truck to the Chevrolet dealer where I purchased it since it was very close. The dealership later inspected the truck and found the lifters had seized and caused damage to the camshaft. They said I would need a new engine at a cost of around $15,000. There were no warning signs or problems to indicate I was going to have an engine failure. The instrument warning lights came on when the engine problem occurred.

I have a 2019 Chevrolet Silverado 1500 LT and I am having issues with the transmission bucking, hesitating, slipping. I am also having issues with the variable timing system. The variable timing system started acting up last year and when I took it to the dealer they replaced it and I was charged over $400 for it to be repaired. It happened again the beginning of this year and I took it back to the dealer. They told me the oil was dirty and suggested an oil change to fix the issue. I had the oil change done and now I am having the same problem again and have already had the oil changed. I need help since I am paying for a vehicle that is sitting in my driveway not being able to be used. There are 6 codes that have popped up including the variable timing system, cylinder 4 misfire, brake system, and I'm not exactly sure what the other ones are.
