Yes, sort of. Electromigration is well known in the industry and there are extensive design rules around making sure you don't violate those rules and hit electromigration limits within the lifetime of the product.
Most IC designers tend to design for the 100k hours at absolute worst case conditions. What is known as PVT: worst case process, voltage, and temperature corners.
Assuming they do that, the likelihood that electromigration actually being the issue is not a concern. Designers can mess up, but generally they don't want to do this... especially in automotive. Auto manufacturers will ruin them if they determine there's a design flaw like this.
