It took Subaru three years to make the BRZ idle without stalling, and there’s like five hundred TSBs now which is par for the course for a ten year run of a completely-new body and engine bay layout. But only a couple of them were meaningfully critical, and one of those was a manufacturer defect that affected several years of car models across the board. So, maybe not to the degree that Cybertruck “dead after 5 miles” and “tried to dead stop on the highway unexpectedly” stories reported are showing.
