I'm not sure how prolific this is (particularly as it sounds like there are a few different iterations on the frunk latch). Our car ahs the double latch and recently the front one has been sticking. I've found two easy ways to open it if does stick. The first is to push down about halfway and hit the open button again, easy if you've got it in your hand. The second way is to push down a bit, and then stick your finger in and push the manual release. (a bit hard to find when the frunk is closed, but its easy to see when open) However, I recently noticed that there was a significant amount of corrosion on the latch and the catch and that this seemed to keep it from sliding open nicely. So I cleaned it off a bit and then put some grease on both pieces. This seems to have at least temporarily fixed the issue, the frunk has opened on the first try ever since. Not sure how long it will last, but the grease should help prevent corrosion too.
