Had a service advisor drive it while it was having the issue and he said oh **** yea I see what you’re talking about now. Left the car, made sure they left it on before the tech drove it, apparently it went back to normal. They said sorry nothing we can do.Sorry to revive an older thread but I'm having the same issue as @Slammy on my stock 2020 Luxe.
First few minutes of driving after warm up it pulls hard/normally on acceleration. But then out of no where I start getting what feels like turbo lag. I'll push the accelerator moderately, the gears change but no power for 2-3 seconds. It basically falls on it's face till the boost builds and this also happens regardless of drive mode.
This doesn't happen all the time but is becoming more and more intermittent. No pending or stored codes and has always ran on 93 octane Exxon or Shell fuel since day 1.
This may not happen for a week then all of sudden on a drive once it happens it keeps doing it no matter how long I drive. Next day it's fine, I don't get it. Thanks for your help in advance. I know the dealer will say I'm crazy since no codes so I haven't bothered with them yet.
