NHTSA Complaint #11458739 — 2017 AUDI S6

I'm NOT sure if this would have developed to an safety issue, I'll let your team decide. At my scheduled 50,000 mile dealer service (50,219 miles) I was informed that both motor mounts had failed and needed replacement. The service rep said that THEY found a fault code for one mount and a visual inspection confirmed that the other mount had also failed. Both mounts had sensors but I DID NOT receive a Check Engine Light of any kind. If the situation would have continued, COULD this have become a safety issue? Maybe? I was also concerned about the "No CEL" in that my car was just 2000 mile out of warrantee, could the mount mount have failed during the warranty period and the system was intentionally set up to NOT let me know there was a failure?
