Engine issue: Turtle icon/check engine sign/Performance Extremely Limited

Started up my car and was immediately shown the error in the picture. I thought maybe the oil temperature needed to be warmed up since it's cold outside. But the engine was vibrating very strongly. I drove the car a block down and the car shook even more (vibrations coming from the engine). I could barely get any power from the car. The RPM was fluctuating as well, getting down to 480-540RPM. Once I got back home a couple minutes later, there was a strong burning smell.

I'll get the car towed tomorrow to the dealer and see what happened. Anyone see something like this before? I use 93 octane if this somehow is related to a fuel issue but I don't think so given the strong vibrations of the engine.

Edit: Also, clicking on the 'i" on this error just leads to "No support is available for this entry."

Production date is 7/11/24. This is a 2024 model. I believe they switched over to 2025 for August/September builds.

I'm sure you've tried, but does it improve with a restart? My guess is not, and what concerns me is the burning smell, wondering if it's trans-related vs engine. Get the shop foreman involved and make them expedite the diagnosis. Best of luck and hope it's nothing too terrible.

No, does not improve. I tried starting the car this morning and it's the same thing but also an another odd noise now. I'm getting it towed to the dealership today. Will update once I have any information.

Hmmm, sorry to hear that OP : ( I wonder if that is a transmission related fault (I mean, the icons does look like it), might be buggy software and nothing mechanical?

Don't know for sure but I highly suspect some sort of mechanical issue. Nothing was modified and no issues before this popped up.

This sux for us all if it's something major. I asked if he restarted to see if it cleared any potential s/w issue but he indicated it didn't help and he now hears a new noise this morning. I also mentioned trans but If it's making noise just restarting (assuming in park) then its most likely not the trans unless the new noise is engine, and the original was trans. Really hoping it's something minor...picking ours up next week and this kind of thing gives me pause especially on an all-new model/engine.

Hopefully it is something simple like software issue, given how many electronics are on these cars.

This is GOOD NEWS - way better than catastrophic engine/trans failure!
