I don't know how to judge the level of bugs vs an arbitrary acceptable level, or to compare it to other vehicles. I do know that my 2020 Acura RDX had 4 software updates to date and (to their credit) they published changed logs. They added very little, but there have been over 150 fixes in 4 years. Or look at a Tesla change log.
I guess it all depends on what the expectations are. I don't think it's controversial to say that this infotainment system is complex. The bugs could be in AAOS, in GAS included with AAOS, in the Ford customizations of AAOS or GAS, or in the downloaded apps themselves. I don't like the bugs either and wish that when I finally get my car that it would operate perfectly, but I think it's naive for anyone to buy this particular car with that expectation.
