Did you all have any warning? Any noise, chatter, etc?

I have a thread in this section with more detail, but the TL;DR is I heard a "pop" noise last night, and now the car is "louder" and I'm getting this clicking/grinding noise that seems proportional to RPM. No CEL, but the noise seems to be getting worse.

My build date is 10/20, so outside the window listed in the TSB, but who knows...

Why do you keep updating? The “Boom” is a bit dramatic as well. Many break and only need springs.

There doesn’t seem to be a warning when they go. If you broke a spring you’d know it. You’d be down a cylinder. Sometimes it drops the valve and that you’d definitely know. That causes engine failure.
I read your thread and I don’t believe your issue is a broken valve spring.

I'm at close to 1200 and nothing bad, so I suspect my springs are good, Build date of 10/20.

It's hard to imagine that you could break a spring and not get a check engine light or code.

If I thought I might have a bad spring, I would grab my Comp Cams tester and test each spring's strength

I feel so bad for everyone/anyone who has to deal with this! Totally inexcusable approach by GM, IMO. This is why I left the brand for decades before coming back to buy my Camaro SS. There's another thread on this that I'm commenting on as well. There are actually members "defending" GM's approach. I don't get it! If anyone went into a dealership to buy any vehicle impacted by this issue and the dealer told them, "Hey, I know you're going to spend tens of thousands of dollars on this vehicle but your engine may go at any time due to a KNOWN issue and GM's approach is screw you, we'll take your money and you deal with the headaches of catastrophic engine failure on a brand new car that could've been avoided.". I can't speak for anyone else, but I'd walk!

It’s not to late. Sell it and move on then. GM is not going to recall all those engines. They are fixing the ones that break. That’s the deal like it or not. I’m just sick of all the whiny bitches complaining every five mins. Sell it and buy a Mustang. They’d love to have you over there. Lmao

No thanks on the Mustang.

And, just a FYI, what you're sick of is irrelevant to me.

Copy that.

There’s a recall now. I found out this morning when I took my car in. They said they will inspect the valve springs. She said the recall came out toward the end of November

[ZL1_2021]

Well, I picked up my 2021 ZL1 on Saturday 12/26/2020 right off the showroom floor and drove off the lot at 4pm. At 7pm, I was calling a tow truck to bring it back. Left the dealership with 7 miles on the odometer and at 76.6 miles, it started misfiring and wouldn't stay running. Spent almost 4hours in the cold waiting for a tow truck through on-star.

Diagnosed it as broken valve spring on cylinder 3. I had to actually make the service department aware of the TSB as they were just going to change the 1 bank of springs under normal warranty. They replaced both banks (16 springs) and the bent push rod on cylinder 3 after contacting TAC.

By the way the latest update to the TSB is PIP5752G which covers the issue to a build date of Oct 7th now.

Finally got the car back 6 days later. Seems to be running good now but they still have not shared the results of the leak down test or the full version of the technicians notes. I have to be leery that the issue caused no damage to the lifter, cam, or anything else.

I told the dealership that if they didn't get GM to compensate me for this BS experience and the time I've had to waste for the lack of a recall (which would have fixed the issue before it happened), that they can kiss my purchase of a new 2500hd Duramax good bye (trading in my 2015.5 LTZ Duramax). Apparently they are now "looking into it" and opening a case with GM to "see what they can do" both on the service side and the sales department. Otherwise they were going to chalk it up as "fix and and move on". This coming from the #1 ranked dealership in my state. It's a shame they have to be "motivated" to provide the best customer service they can.

Really makes me wonder why I just spent over 60k for a "brand new" car. They are lucky I love the car, because that is the one thing they have going for them with me at this point. If they won't issue a recall, then they sure better make it worth my while and compensate me to deal with the break down ON THE 1ST DAY OF OWNERSHIP! Not even 4 hours after leaving the showroom floor. SMH.

Wow.

Very sorry for your experience. What you went thru on day 1 couldn’t have been scripted worse, and would certainly have me seeing red also.

I’m in agreement on your opinion of GM here, and feel a written response/apology with some sort of olive branch extended is in order. They’ve made the car right and will stand by it for the duration of the warranty, but to me it’s the principle of what you went thru that requires action on their end. That said, I realize how naive I am to suggest GM would do this.

It also needs to be said that although difficult don’t indict the car based on this one issue. These cars are absolute beasts, and mine has been perfect so far. Welcome to the forum and congratulations on owning such a great car.

Ugh, not good, not good at all. I feel for you, I’d definitely be more than a little bit disgruntled. I wish you the best of luck, “hopefully” this is just a bump in the road.
