We run into some similar issues, too.
Example: Japanese OEMs do not require to have TS certification, but some customers in the U.S. require certification to TS, because they just write their supplier manual based on what's written on TS standard. One of the customer requires TS certification although their customer (Japanese OEM) does not require it. We had a situation where the 3rd party auditor asked us if we had confirmed if the customer was okay with ISO certification of our parent company because we supply some parts made by them, then when I could not provide our customer waiver, they would write up a CAR. To this day, I still ask their purchasing department for their purchasing policy, and I get no response.
I hate when they do this to everyone, doing one size fits all thing. Automotive industry is supported by many small companies including small local mom & pop shops that have incredible craftsmanship, and they need to realize that not all businesses are capable to be run the same manner.
