Believe it or not the mfg is responsible for the quality of the car, not the country.
Quality Iphones come out of China because the mfg has chosen to hold the supplier to a high standard.
If VW et al can't produce a quality car in mexico, it is largely their choice. JMO.
yes the manufacture decides the procedures to put in place to control the quality of their cars. But rules only go so far. The local suppliers, even down to raw material, also have something to do with the quality. Cheap metal is still cheap metal no matter how well engineered the final product is.
it’s a double edged sword. You could say because they cut labor costs by moving production to Mexico, they could invest in the quality control. You could also say the workers there have more motivation to work and keep their job.
It’s not possible to reject a bad batch of cars like they can reject a batch of bad iPhones. Apple might lose a few hundred dollars per unit. If VW or any other manufacture rejects a car they lose much more, so they have reason to just deal with after sale warranty work. The end consumer gets the shaft because the dealer says it’s “normal”, the problem is intermittent, or the problem only occurs after warranty is up.
granted I’m not saying the same issues won’t happen with American, German, or Japanese built cars either. Just less likely in my experience.
