Video: 13K miles and my first real issue

[burn813]

I have the car at the dealer, and I hope to learn more information, but right at about 13K miles, the supercharger started knocking on start and had a light grinding. It felt like it was a little down on power, but I didn't notice anything from inside of the car and if it wasn't for my wife being outside of the car when I started it, I am not sure I would have caught it so early. The car is currently at Elco Cadillac. They have inspected it and do believe that it is the SC. They have ordered a new unit and hopefully it will be back on the road soon. For anyone who is wondering, there was no CEL and there was not really any indication inside of the car.

Not all too common but, I’ve heard instances of the snout bearings going bad on some LT4s. Great that they’re taking the route of just replacing the supercharger.

Bummer, that’s real scary hope it’s nothing else. I’m sure dealer will take of it including oil change,I would ask for oil testing for piece of mind.

I have been down this road with my '16 CTS-V. Same issue. SC replaced and all was good.

So I spoke with the Service advisor at Elco, he said they opened a ticket with GM, GM responded and asked them to send the whole unit to them so that they could diagnose what happened. @Mirza Grebovic FYI

Any idea how long it will take to get a new SC?

At least the problem was easy to ID and the shop seems to know what to do. That part is comforting.
Hopefully you will be back in the drivers seat quickly

The service advisor said "it's ordered", and "a few days"

Somewhere in Lansing, a 5BW on the production line just got flipped to MP status.

The good news is that, of all the engine components that could possibly experience catastrophic failure, the SC is just about the easiest to replace "cleanly".

It would be cool if they could install a SC with a Kong LT4X porting under warranty.... but that's just not how this world works.

I told @Mirza Grebovic that we needed to just grab that 2650 from the escalade-v and pop it on there
