I had an OTA update brick my Tahoe infotainment system. Now that backup cameras are standard requirements, those were all unusable. Also affected things like the clicking sound you hear when you use your turn signal. That was completely silent. Cost me ~$2k to get it fixed and wasn't covered under warranty. Good stuff. I've disable future "updates".
An FYI for the future, but backup cameras are considered a safety system and manufacturers are required to repair issues they've caused in safety systems regardless of warranty status. The appropriate escalation if the manufacturer doesn't recognize this is to get NHTSA involved with a safety complaint [0]. That's the main way recalls happen.
