North American auto assemblies slipped in September

North American auto assemblies declined in September, down 5.1% vs. August. And, according to GlobalData, assemblies were also down 1% year on year.

After a hard drop in December — the worst since July 2021 — assembly numbers rallied in Q1. But numbers were inconsistent throughout Q2 before a seasonal summer slump in July. Now, while September totals are down month-on-month (m/m) and year on year (y/y), they are largely above the 2025 year-to-date monthly average of 1.29 million units.
