This is key. It's just going to fail again. They didn't change anything about the design, and owners might find it difficult to get their vehicles covered because the letter instructs you to NOT bring your vehicle in unless there's a check engine light. Failure of the missing intake manifold will not trip a check engine light unless it is a contributing factor to another fault (P0299, for example). What's worse is, that entire time, you'll be burning more oil (which will poison the catalytic converter, which they won't cover), lose fuel economy, and lose responsiveness/power. Based on boost leak testing, we've seen the OEM valve start leaking after around 30,000 miles, even before it outright fails!
However, if you do get GM to replace it, this would be a perfect time to install the V3.4+ PCV Fix Kit. This kit has 2 years of maturity and reliability, with several improvements over the years. Having a new intake manifold allows you to get a fresh slate to install the kit as a preventive measure, since you won't need to clean out a ton of deposits. The V3.4+ kit is a true redesign and upgrade to the PCV system that makes the check valve easily serviceable. A failure-prone replacement manifold will ultimately not offer you the peace of mind of knowing you can swap out a valve in 2 minutes, and the kit comes with two valves so you always have a spare in the glove box.

Got that same letter almost 2 years ago for my 2012. Took into dealership with all my other $1,ooo's & $1,000's of dollars, Not joking at all and was told I was over the year mark, and 5000 over the mileage. I showed him my handy dandy 3 ring binder that is almost full of repair receipts, at the time 3 year maybe of ownership. Needless to say the German/Irish came out in me, and I let it be known throughout the whole dealership as well as parking what 🐔 s**ts they were. 5,000 miles over, still shake my head over that.
Bring in the parts receipts at least. Maybe you can get that.
Thats the plan. I included the Fix Kit cost, too. Its cheaper than a replacement intake manifold. LOL

I replaced my valve cover with an Amazon aftermarket about 3 weeks ago. The original was leaking oil out of the front. The replacement went well but I got a CEL P0171 the next morning. I also started to get a chirping sound. I pulled the cover and cleaned everything up again and reseated it very carefully. This time it started spraying oil out of the back side due to the gasket getting pinched. I purchased a new Fel-Pro gasket and installed it and I haven't had any oil leaking, but I still have a CEL, chirping after the car has ran for a while, loss of power, stumbling, and rough idle.
I have the fix kit but when I went to install it I found my check valve/nipple still intact. Thus, I didn't install the kit. Your comment I quoted implies that it can be installed even when the OEM valve is present, but how?
I'm at my end with this car at this point because I don't know if it's the valve cover, intake manifold, crankshaft seal, or something else. I have 72k miles on it fyi.
P.S. I received the same letter as the OP, but I can't take it in because i only have 1 car and none of my local dealers have loaners because of the chip shortage.

Why not wait for it. The repair doesn't take much longer than an hour or so.
It could be all of the above as they all can be symptoms of a bad PVC valve, including one that looks like it is ok. I suggest you let the dealer do its thing and then install the fix kit as well.

The dealers around me a backed up so I'd have to drop it off and they would take a couple days to even look at it. But in the event I did have it replaced, or even just leave the original on, how can I install the fix kit? Wouldn't I need to remove that nipple in order to plug it? I'm willing to try whatever at this point seeing that I already have the kit and a car that runs like crap.
Here's how to install the version 3 one
