If that was a main factor, surely then Mexico should be ground zero for next-generation car electronics design? Like, Tijuana or Ciudad Juarez.
On paper Mexico reaped enormous gains from NAFTA(/MCA) but those went to a small slice of the population, and people on fixed incomes/not in manufacturing/services objectively got worse due to inflation and rising cost-of-living, property prices. The share of GDP effectively lost due to corruption is also an issue.
