Surprised binding 2004 shifter has not resulted in a recall

I recently resurrected a high mileage (243,000 mile) 2004 Prius that was destined for the scrap yard due to a failed head gasket and other minor issues including a binding shifter assembly.

Many Prius chat members with a 2004 Prius have reported that their shifters can stick in the drive or reverse position due to a warped shutter and when this happens the park button is disabled (this condition had resulted in quite a surprise to me on more than one occasion).

I was easily able to fix this issue by trimming a plate to make up for a warped shutter but I bet there are a lot of non MacGyver people still driving their unsafe sticking 2004 shifters due to the high price a dealer would charge to replace the shifter assembly.

I filed an online NHTSA report.....hopefully my report and others can help the folks out there that are living with this saftey issue

 

It looks like 7 complaints (would 7 reports likely indicate 70 plus shifter failures?)
I would hope it wouldn't take a death to become a recall
