Default On board computer data??

Hello I'm new to the forum and actually writing this for my daughter who owns the Corvette it's a 2024 and I don't know anything else about model, etc. The reason for this post is she had some work done at the local dealer and when she got it back it was in track mode so on and so forth and she's wondering if they drove it like they shouldn't have as it was only in for an oil change and a 7500 mi service n checkup. Even more suspicious is that they deleted the data on the SD card so she can't look back at that. So she's wondering if there's any way the onboard computer or the Northstar system would have captured anything and if so how do you go about getting that data thank you appreciate everybody's help in advance

This is mostly true. It will only start in My Mode or Tour mode. I know because mine is also a 2024

I'm pretty sure my '22 CTF starts back up in Sport mode. If not, I've been fooling myself for a couple years.

Not from the dealer that did the service, however. If they deleted the PDR files, would you expect them to come clean on what was indicated from the ECM data? If something untoward was discovered, then confront the dealer/service department where it was first taken to. Either way, I'd confront that dealer and ask why the PDR files were removed. ...and never go back there again.
