General Motors Corporation — Corporate Overview

Premises Description

General Motors Corporation (founded 1908, headquartered Detroit Michigan; today General Motors Company after 2009 reorganization) was through the 20th century the largest U.S. automobile manufacturer and operated an extensive network of U.S. assembly plants, foundries, engine plants, transmission plants, stamping plants, and downstream component operations. Major GM asbestos-era U.S. operations included:

  • Detroit-Hamtramck Assembly (Detroit MI) — flagship Cadillac/Buick plant
  • Flint Assembly Complex (Flint MI) — historic Chevrolet/Buick plants and the Buick City complex
  • Lansing Car Assembly (Lansing MI) — Oldsmobile plants
  • Lordstown Assembly (Lordstown OH) — Vega and later Chevrolet plants
  • Wentzville Assembly (Wentzville MO) — GM’s St. Louis-area complex
  • Janesville Assembly (Janesville WI) — closed 2008
  • Arlington Assembly (Arlington TX)
  • Fairfax Assembly (Kansas City KS)
  • Spring Hill Assembly (Spring Hill TN) — Saturn complex
  • Defiance Foundry (Defiance OH) — engine block castings
  • Saginaw Steering Gear / Delphi (Saginaw MI) — components
  • AC Delco / Delco-Moraine Brake (Dayton OH and elsewhere) — friction products
  • Stamping plants at Mansfield OH, Marion IN, Pittsburgh PA, and Parma OH
  • Truck plants at Flint MI, Pontiac MI, Janesville WI, and Pontiac MI

GM foundries (Defiance, Saginaw, Tonawanda NY, Massena NY) were particularly asbestos-intensive — operating cupola furnaces, electric arc furnaces, and high-temperature mold operations through the asbestos era.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that General Motors — as premises owner — exposed its UAW workforce, contractor pipefitters, insulators, boilermakers, and trade workers to extensive asbestos.

General Motors has been named as a Premises Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.

Documented in Public Court Records

According to publicly filed federal asbestos litigation records (reviewed via CourtListener/RECAP), General Motors has been named in 500+ documented asbestos dockets filed between 1989 and 2024 — concentrated in the federal asbestos multidistrict litigation (In re: Asbestos Products Liability Litigation, MDL 875, E.D. Pennsylvania) and other U.S. district courts.

In these publicly filed cases, General Motors is most often named alongside other companies frequently sued as co-defendants in the same asbestos actions, including General Electric, Metropolitan Life Insurance, Ford Motor, Owens-Illinois, Crane Co., Honeywell International, A.W. Chesterton, Foster Wheeler.

Case counts and co-defendant associations are drawn from publicly filed litigation records and reflect allegations, not findings of liability, which is determined case by case.
