Thanks all for the feedback. The dealer is diagnosing it now and I just want to have an idea of what the problem might be.
So you had the car stall 2 different times with one being the fuel pump module and the second time it was an engine failure? What engine did you have...5.3 or 6.2?
I got a call from the dealer, and while they are not done with the diagnosis, they said they found metal in the oil and believe it's an engine issue. I have only ever had Hondas and Toyotas and am frankly in shock that a brand new engine would already need to be replaced. Has anyone had their 5.3 engine replace within the first year? If so, did the replacement engine work fine for several years?

This will be a bit unusual if your 5.3 seized the way some 6.2s have.
...But most other failures I've read about here have been accompanied by a message on the screen about the truck being unable to shift, and folks have had to coast in neutral to the side of the road. Did you have this occur, too?

Unfortunately, FPCM failure seems to be relatively common. As mentioned, mine went out at 320 miles, I hadn't even owned the vehicle for a week at the time, so it was new-new. Must have been a defective part from the supplier to go out that early. That was in September, I got it back a day or so later and now have 2,500 miles with no further issues as of yet.
I saw your other reply about the dealership finding metal in your oil, so it seems you might have a more serious issue. Metal in the oil basically always results in needing a new engine. Please keep us updated, it's good to share the experiences we have with these vehicles. I feel for you though, having a new vehicle engine brick itself is an awful experience, it's highly inconvenient, and erodes trust in the vehicle even after repair. Being it's so new, warranty should handle the repair and you'll get it back in working order, but it still takes a toll on time, convenience, and trust.
Regarding your question about 5.3L failures under a year, besides a period of time around 2021 when GM received a bad supply of lifters, having a 5.3L fail within the first year is unusual. I'm on my third Tahoe, and my prior two both had the 5.3L. My 2008 went 11 years and 160K trouble-free miles, my 2019 went 5 years and was at 50K trouble-free miles when I traded it in, it was running perfect at trade-in, I just wanted a new gen with the 6.2L. My experience with those two 5.3L engines was excellent, they never let me down and a reason I'm a fan of these vehicles. I'm hoping my current 6.2L will serve me reliably, besides that little hiccup at 320 miles with the FPCM.

Thanks for sharing all of this. I stopped by the dealer and the technician showed me what happened. Part of the piston broke apart and he said he has never had to replace an 5.3 engine with the current gen Tahoe. I guess I am just the unlucky one. Also, the engines are on back order so I have no idea how long it will take to fix. They gave me a small SUV loaner but I am demanding a full size comparable replacement since it's still under warranty. I hope the replacement that they send has been fully tested and will last longer.

I have the 6.2. GM put out a bulletin on it but no recall. Sounded like marbles in the engine when it failed also metal shavings on dipstick

6.2
Have you heard back from the dealer after they diagnosed the issue?
