2017 ZL1 with A10. All current service bulletins have been addressed by dealer already at the last maintenance visit about a month ago. Had a difficult and sluggish start this morning with shuddering. It turned itself off after 6-8 seconds. Second start was smooth and normal, but check engine light remained on with alerts to service rear axle and stabilitrak. I have seen other posts relating to similar experiences, but I took a video of the produced sound after reversing from the garage. Car is currently at the dealer for resolution. I will attempt to upload the video here and post more info after I hear back.
