Crankcase (pcv) problems of the 2019 Chevrolet Malibu

I understand that the vehicle is outside of its original warranty period. However, I do not believe that the expiration of the warranty should automatically make me responsible for a component failure that occurred at only approximately 39,000 miles. The pcv valve and orifice are not routine maintenance items that I would reasonably expect to require replacement at such low mileage. Unlike tires, brake pads, batteries, or other components that are expected to wear out and require periodic replacement, the pcv system is an integral part of the engine's emissions and crankcase ventilation system. A failure at only 39,000 miles seems premature and should not reasonably be characterized as ordinary wear and tear. More importantly, gm itself has acknowledged problems involving the pcv system in Chevrolet Malibu vehicles. Gm technical service bulletin and TSB 18na246 and TSB 20-na-047 specifically addresses plugged pcv orifices on 2016–2022 Chevrolet Malibu models and provides a diagnostic and repair procedure for this condition. The bulletin identifies the pcv orifice as the causal part associated with the condition being addressed. I recognize that a technical service bulletin is not the same as a recall or an extension of the vehicle's warranty. I am not claiming that gm is necessarily obligated to repair the vehicle under the expired warranty. Rather, I believe gm's own technical documentation demonstrates that this is a recognized issue involving a specific component and is not simply an ordinary maintenance item that a customer should reasonably expect to replace at 39,000 miles. The approximate cost of this repair is $1300 for a failed $40 part!! even gm changed the design of this component because in years past and newer years this part replacement was a 20 minute job, not a 5 hour complete replacement of the valve cover! failure to repair this faulty design could lead to excessive oil loss and immediate loss of power due to the engine ceasing.
