Al Engel. "Save the Wave"
The widespread issue for cars made through August 2020 was ~10 folks who had their Frunk open will driving. 2 or 3 had it flip open and cause damage to the hood. GM changed the software for cars made after ~September 1st 2020 and now has improved warnings, a special sequence to open with your FOB to reduce chance of a "cell phone like pocket call" inadvertently opening the Frunk. Most important, IF you are distracted and don't see the dash warning of "Open Frunk," car won't go past 26 mph! That will get your attention. It appears car had to be going ~35 mph to have the air lift the Frunk up so now that max 26 mph will get those folks texting while starting etc and not paying attention!
The significant issue but limited to certain cars was a bad valve spring. Was not just C8s, all LT2s and perhaps some other V8s. It typically happened within the first 500 miles. After that not likely. No count on how many were affected but a small percent of cars built in a specific time period. Dealer would change valve spring without removing a head or engine ~90% of the time.
Another wide spread issue was the 50% of folks who bought lifts. Cap leaked under certain conditions. GM just changed to a Blue different cap that looks like it solved the fluid dripping issue.
Other issues are mostly typical random occurrence "infant mortality" issues with a new car.
