If by saying that many people can now report “NO” or at least “very few” problems, you mean “mechanical problems”, then I would tend to agree. My GGT was delivered right before Thanksgiving and has only had two minor mechanical issues. Second row seat will not fold forward without a little assistance from me and on just a couple of times, the frunk has done the double try to unlatch. Everything else - mechanically - is great.
As for software, I would highly doubt that very many people (if any) are having ZERO software issues. Those who claim to not have software issues are either very forgiving of issues or have not driven their Gravity long enough. I guarantee that if driven more than a couple weeks or more than a couple hundred miles, everyone will have some software issues.
On my GGT with 3.3.20, DDP is a 50/50 proposition. Sometimes it engages perfectly. Then next time it takes numerous taps of DD button before it will engage, then next time it will engage fine but within 5 minutes will get DD errors and disengage. Another day start up to drive and no audio and it took a reset to get it going again. Another day right mirror stayed in the down position after backing out of garage (had to hit dash mirror reset button.)
Periodically get the auto headlight error message and a couple other miscellaneous errors. Couple days ago when showing off car to friend, pulled up Tidal and got horrible crackling sounds and had to switch to Sirius to get it to go away. Then after having fob work perfectly for many weeks, I go to show car off to my brother and fob refuses to work, shake it -nothing, try fob buttons - nothing, finally used key card and car opened and started fine. Fob has been working great since, so not battery issue.
None of these issues are game ending and most go away at next car start. It is just that there are way too many software issues still going on (even post 3.3.20) that I have a very, very hard time believing that people are driving Gravity with no software issues.
