Prior to yesterday there were 43 posts on this thread and maybe 3-4 people that had any type of issues. Since yesterday there are 3 people all with '22 models that are stating issues.
While some people have issues with the lockers I think this thread is a perfect example that shows many "issues" with vehicles are not nearly as common as internet forums make they appear. As stated in an older post most people will only join these forums when they have problems and looking for solutions....everybody will jump on the internet to complain about an issue on every forum they can find, but nobody ever gets on a forum and says "yep, my lockers are working like they should".
Per some charts I found they claim over 25,000 Gen 4 (2010 to 2018) Power Wagons were produced for US and Canada. So if only 1% of those trucks have an locker issue (and I doubt it's that high) you have 250 trucks with issues. Now you have 10% of those people jumping on the internet and making posts, which is 25 posts. If somebody got on this forum for the first time and found 25 people posting about locker issues you would think it was at epidemic proportions and most PW's made had locker issues. However in reality that is 25 out of 25,000 trucks, or 0.1% (one tenth of one percent) that you are hearing about.
