Maybe, maybe not. We can look at the actual quality of the new cars instead of trying to guess.
The high rework rate could be because they catch a lot of mistakes. That would clearly be a good thing. But given what we actually observe from their cars it seems more likely that they catch mistakes with an average success rate but produce more mistakes than normal. That means both more rework, and lower quality because of all the uncaught mistakes.
A lot of people have declined their Model 3's at the dealerships due to issues, even knowing that means they go back onto the wait list.
There are tons of threads about this issue on the Tesla Reddit forums. Less so for Tesla's other vehicles.
Model 3 is completely different beast. If they succeed manufacturing it 5000, then 10,000 per week, the quality must be up if they want to make money.
For instance, mine had body damage from a road hazard - not an issue of quality, but definitely needing repair. It took a few weeks before the parts were available.
As you can imagine, if your car isn't drivable in the interim that's a big pain and rental bill, but if it is drivable then you just have to wait longer.
A high rework rate is a huge red flag for at-scale manufacturing and says that something is wrong.
It seems like this should be obvious. How healthy is a software engineering environment where 80% of the commits fail at the tail end of the development pipeline and require fixes? I’ve never seen an org that bad.
