General Motors Headquarters Address, Corporate Office Location, and Contact Details

About

General Motors Company (NYSE: GM) is the largest automaker in the United States and one of the world’s largest automotive manufacturers, headquartered at Hudson’s Detroit, 1208 Woodward Avenue, Detroit, Michigan 48226 — a landmark new address that marks GM’s fourth headquarters location in its nearly 120-year history in Detroit. GM officially relocated from its longtime home at the Renaissance Center on January 13, 2026, occupying the top four floors of Bedrock’s iconic $1.5 billion Hudson’s Detroit development — built on the historic site of the former J.L. Hudson Department Store, and returning GM to Woodward Avenue where it first established a Detroit presence in 1911. GM was founded on September 16, 1908 by William C. Durant in Flint, Michigan and grew rapidly through acquisition — absorbing Buick, Oldsmobile, Cadillac, and Oakland (later Pontiac) in its earliest years. The company expanded to become the world’s largest automaker for most of the 20th century before facing its defining crisis: a government-backed bankruptcy in June 2009 during the global financial crisis, emerging 40 days later as the “new GM” with a restructured balance sheet, reduced brands, and a path to profitability. Under Chair and CEO Mary Barra — the first female CEO of a major global automaker, appointed in 2014 — GM has pursued a dual-track strategy of sustaining its highly profitable full-size truck and SUV business (Chevrolet Silverado, GMC Sierra, Chevrolet Suburban/Tahoe, GMC Yukon, Cadillac Escalade) while investing aggressively in electric vehicles. For FY2025, GM reported total revenue of $185 billion (-1.3% YoY), net income of $2.7 billion (-55% YoY), and adjusted EBIT of $12.7 billion — with the net income decline driven primarily by $7.2 billion in special charges related to EV capacity realignment and China restructuring. Despite the charges, GM sold 2.85 million US vehicles (+5.5% YoY) and ranked second nationally in EV sales. GM’s 2026 guidance calls for net income of $10.3–$11.7 billion and EBIT-adjusted of $13–$15 billion, with planned US annual production rising toward 2 million units.

About the Hudson’s Detroit HQ: GM’s new global headquarters at Hudson’s Detroit is the crown jewel of Bedrock’s $1.5 billion mixed-use development — the largest real estate project in Detroit’s history — anchored by a soaring glass skyscraper on the former J.L. Hudson department store site. GM occupies the top four of 11 office floors, with executive offices, collaboration spaces, and a street-level vehicle showcase area. The new campus drew architectural inspiration from Eero Saarinen’s iconic GM Global Technical Center in Warren, Michigan and features work by prominent contemporary artists including Detroit’s Harry Bertoia. GM’s move from the labyrinthian Renaissance Center to this sleek modern campus is widely viewed as a symbolic statement of confidence in Detroit’s revival and GM’s own forward momentum under Mary Barra. The Renaissance Center — GM’s home since 1996 — is being evaluated for redevelopment with Bedrock Detroit advising, with its future use not yet formally announced as of April 2026.

How to Escalate a Complaint

1. Contact your GM dealer first — All GM vehicle sales and service are conducted through independent franchise dealers. For warranty claims, service disputes, and recall work, the dealer is the primary contact and has warranty authorization authority.
2. Call your brand’s customer assistance line — For complaints not resolved at the dealer: Chevrolet 1-800-222-1020; Buick 1-800-521-7300; GMC 1-800-462-8782; Cadillac 1-800-458-8006. GM’s regional customer care team can authorize goodwill warranty decisions and mediate dealer disputes.
3. Request a GM Regional Manager review — If your case is stalled with customer assistance, explicitly request escalation to a Regional Customer Experience Manager — they have authority to approve goodwill claims beyond what phone agents can offer.
4. File a Lemon Law claim — All 50 states have Lemon Law protections for vehicles with recurring defects. Contact your state AG’s office or a Lemon Law attorney. GM participates in BBB Auto Line (1-800-955-5100) arbitration as a pre-litigation step.
5. File a safety defect with NHTSA — For safety-related defects, file at nhtsa.gov/report-a-safety-problem. Sufficient NHTSA complaints can trigger federal investigations and mandatory recalls.
6. Write to the Detroit HQ — Write to General Motors Company, Customer Relations, 1208 Woodward Avenue, Detroit, MI 48226. Send certified mail. Include your VIN, dealer name, case number, and resolution requested.
7. File with the BBB — GM is listed with the BBB. File at bbb.org.
8. File with the FTC or Michigan AG — For deceptive dealer practices or advertising violations, file with the FTC at reportfraud.ftc.gov or the Michigan AG at michigan.gov/ag.
