Hiding in plain sight: Tariffs quietly driving up costs of autos, auto parts

MISTA analysis: Higher auto sector costs due to tariffs showcase need for smart and consistent trade policies

LANSING, Mich. — Erratic trade policies are driving up costs for automakers and families in some surprising ways, hidden in higher prices for cars and auto parts.

An analysis by the Michigan Smart Trade Alliance (MISTA) found that tariffs on the components that go into autos and auto repair totaled billions during one six-month period alone since tariffs took effect in 2025.

“This comprehensive review shows the widescale impact tariffs and unpredictable trade policies have on our economy and families' pocketbooks,” said MISTA spokesman Mark Fisk. “These hidden costs are falling on everyday Michiganders, giving another reason for Congress to listen to their constituents and enact smart and consistent trade policies that lower prices for families and allow our state’s automakers to compete on the world stage.”

A MISTA analysis looked at cars and auto parts subject to tariffs under a March 2025 Trump Administration proclamation and examined the total amount of estimated duties from January to June 2026 compared to the same period two years earlier based on United States International Trade Commission data. The estimated amounts are staggering:

• Wiring, signaling, lighting, gauges, radios and defrosters: $1,176,509,246
• Engine parts and related items: $1,058,888,483
• Transmissions, gearboxes, and axles: $774,800,909
• Tires and wheels: $661,811,020
• Bodies and bumpers: $519,780,984
• Steering and suspension: $458,525,752
• Brakes and brake parts: $277,125,249
• Locks, hinges and bearings: $220,323,235
• Windshields and mirrors: $92,327,413
• Seats and airbags: $73,040,788

“Our polling shows Michiganders understand that every additional dollar paid in tariffs is ultimately more money out of their bank accounts,” said John Sellek, a MISTA spokesman. “Congress needs to act to stop this hidden tax on Michigan families and to enact stable and consistent trade policies.”
