I have a number of these engines and cars and HAVE NOT experienced any ZINC Pest issues.
However, if the issue is in ONE model it's likely pervasive because the material batching wasn't changed for me.
It is just a matter of time until it appears. The only answer is for manufacturers to list defective and potentially defective engines, cars and specific parts so we can all know it, avoid it or accept it.
I have not seen a compiled list just occasional postings.
