2025 CT5BW Line Lock

[USMC1911]

Curious if anyone has figured out the process for using the line lock on the 2025 CT5 Blackwing with the manual? I got it to the point where the parameters are met and I figured out how to use the launch control but the line lock I'm having a problem with. When I turn it on and press the gas, it doesn't lock the front brakes or rev the motor, it just sits at idle and I have to trun traction control back on or it won't rev past dile and acts like it has a dead pedel. I gotta be doing something wrong and have spent WAY to much time trying to figure is out. Any help would be awesome and a video would be fantastic!

I'm assuming it's going to take more than a Band-Aid to fix on above poster's vehicle.

Thanks for posting up on the line lock feature and also for the description. I'll have to look into it.

That's an excellent question for GM. It's been at the dealer for a total of 47 days now across three trips for electrical issues that started two days after I picked it up from the dealership in February. An array of dash lights and warning messages, progressing to a no-crank-no-start condition, then to the point where the exterior door handles don't even respond to requests to open.
An incredibly frustrating experience and a real black cloud over my first new vehicle purchase and first Cadillac ownership.
Service department's next steps is to get approval for and replace the entire engine wire harness, and keep troubleshooting, and I'm waiting on GM corporate to offer any other path to resolution besides keep waiting on a broken six-figure car while I putz around in a CT4.
