My 2018 570 spider doesn’t have issues often either. Occasional “tuner not found” (just need to hard reset it by holding the button), and key not found very rarely if I have the key against something like my phone occasionally (had it happen yesterday for a minute, but that was first time in months). I’m sure it’s the same tech in my spider that’s used in the 720. Other than the really rare occasions above, everything else works fine.
My 18 had a couple of things reprogrammed and all is fine. It does take a few seconds for the computer to boot up, the binnacle to open, and the seat adjust to be available, so don’t use it for a getaway car with the engine off.
my 2018 after the last software upgrade, no issues. Car is awesome... biggest electric issues WERE radio cut out, park sensor errors, suspension faults and camera. everything fixed after last software upgrade. Car is great.
