Reduced Accelaration

[SC-CTV4BLKWING]

Good morning - I have a 2023 CT4 BW with 12,100 miles on it and on Sunday when I started it up the engine light came on with the message about reduced acceleration. I didn't drive it on Sunday, Monday morning I drove it on tour mode (as I normally have it on my mode with a louder engine sound) and the light went out, yesterday later in the morning the light came back on when I was driving it in my mode. Has anyone experienced this? It's going into the dealership tomorrow. Just seems so random as it was fine when I parked it Friday after work.

The first thing I do when I get a check engine light is get out the scanner. I don't like to be at the mercy of others telling me things I can find out myself. Even if you can't self-repair, you can go to a shop with some foreknowledge.

I took it to O’Reilley and had it scanned, said no fix available. When my husband talked to the dealership they would scan it with their scanner. We will find out tomorrow….

Results from taking car to dealership - apparently there was an update that Cadillac/GM was aware of - did update and everything is fine.
