I purchased a buy back 23 z06, because GM took too long to replace the engine after it was ticking and they determined it needed a swap. The previous owner contact BBB and got them involved. That's what I would do in this situation. From my records, it took gm a full year to get another engine in the car, near as I can tell. Previous owner was not willing to sit and wait on the dealer and GM to do the right thing. Look up BBB AUTO LINE buy back program. Get the BBB involved.
I will say that my car has been great since they swapped the motor, so I think whatever happened in 23 they figured out.
Just a car to them... in their defense they handled my '25 Lemon repurchase very well and I have a '26 now, but for $145K the cars are just so inconsistent in quality / assembly. But for fun I searched used Porsche GT3 manuals under $180K. There are 12 on Autotrader nationwide and all 996s 20+ years old. So there literally is no other car that gives you nearly 700 horse and this capability anywhere close to the money; and they know it.
Yeah and then on top of that you have Volkswagen Porsche longevity issues. Cylinder bore scoring, IMS bearing, cracked strut towers, GT3 engines blowing, etc.

BB auto line is sponsored by the the car manufacturers I believe.
OP, this sucks...I feel bad for you.
If I understand what you said is that you had an engine failure and GM has agreed to replace the engine under warranty. The issue is it is taking over 10 weeks for GM to send the replacement engine to your dealer. If this is correct I think the toughest part of the battel is over, GM has agreed to being liable for the engine replacement including parts and labor.
What is GM saying the reason is for the delay in producing the replacement engine?
‘there is no reason or communication from GM. The dealer is in limbo too. Customer service is sympathetic and offers apologies, but I feel they have no power to rectify the situation. I mean I could order a new car and have it in this timeframe. They are not the hot item anymore. They are sitting on dealer lots. I don’t get it.
I had to deal with GM and a replacement engine for months. Here's what I did:
I contacted my State Attorney General's Office and filed a claim with them. Most have a consumer protection division. I provided all the necessary documentation, warranty information, etc., and they went after GM for me. Cost me $0, and I had a new engine two weeks after they started the case against GM.
I'd go that route before spending $ on an attorney.
It’s been 10 weeks since my 2023 Z06 blew the engine. It had 8k miles. There is no eta for a new engine. GM customer care keeps apologizing but is otherwise useless. The cars are still being built, it’s not a parts issue. Why can’t they find a way to have engines ready for loyal customers? They surely can, so why don’t they? They just don’t care. Even at these price points. What a joke.

GM took care of me when my first new chevy, a 24z, was in the shop more than a month in 6 months of ownership. It wasn't just one issue but a number of things. While frustrating, they agreed to buy it back and I have a 25z that has been much better. Finding a good dealer is more than half the battle too. I hope they quickly come through for you!

Years ago I had a new Escalade explode in my garage with 900 miles on it and less than a month old, my Caddy dealer got a new engine and had it installed in less than a week, and reordered a brand-new Escalade to replace mine, and I just told them I was going to see a lemon law lawyer, but never needed to, they took good care of me.

This is a good idea… the AG in this state has gone after several companies enabling consumers to get full refunds.
GM operates like insurance companies… the corporate goal is to generate as much revenue as possible through vehicle sales, subscription fees… and until the Feds banned the practice… the sale of customers driving data…
While minimizing costs… Warranty claims are costs. The slower they honor them the more money they make…
Any car manufacturer that has PROFITS, not just revenue but profits, in the Billions of dollars… that goes to the effort to secretly collect and sell customers driving data to make a million or two more… (that doesn’t round in their financials…) knowing that the practice will absolutely harm their own customers…. tells you all you need to know as to what GM “cares” about.
