Walk into any Chevrolet dealership right now and you'll feel it. The sticker prices aren't just nudging upward; they are jumping. It’s not just "inflation" or "the economy" in some vague sense. Honestly, it's the math of a trade war hitting the pavement.
When people talk about auto tariffs General Motors has to deal with, they usually imagine a big wall at the border. They think it's just about stopping foreign cars. But if you're GM, the reality is a lot messier. It's a logistical migraine that costs billions.
Mary Barra, GM’s CEO, recently admitted that these tariffs had a "few-billion-dollar impact" over the last year. That’s not pocket change. Even for a giant that moves millions of Silverados.
The story here isn't just about protectionism. It's about a 118-year-old company trying to rebuild its entire nervous system while the rules of the game change every six months.
Why Auto Tariffs General Motors Faces Aren't Just About China
Most headlines focus on the 100% tariffs on Chinese EVs. Sure, that keeps BYD out of the driveway for now. But GM's real headache comes from closer to home.
In early 2025, the landscape shifted when 25% tariffs were slapped on imports under Section 232. This didn't just hit finished cars. It hit the guts of the vehicles. We're talking about the sensors, the seat frames, and the wiring harnesses that cross the Mexican and Canadian borders multiple times before a car is even finished.
GM imported roughly 750,000 vehicles from Mexico and Canada in 2024. Think about the Chevy Silverado or the GMC Sierra. These are the profit engines of the company. When you put a 25% tax on the non-U.S. content of a truck made in Silao, Mexico, the price tag in Ohio starts to look scary.
The MSRP Offset: A High-Stakes Game
The government did throw a bone to Detroit. It’s called the MSRP offset program. Basically, if GM builds a car in the U.S., they can get a credit of 3.75% of the sticker price to help cancel out the tariffs they paid on the imported parts.
Barra actually praised this. She said it helps create a "level playing field." But there’s a catch.
To get the full relief, the vehicle needs to have at least 85% of its parts sourced from the USMCA region (U.S., Canada, or Mexico). That threshold is scheduled to climb to 90% by May 2026. If you don't hit those numbers, you pay the full freight.
- Phase 1 (Through April 2026): 3.75% credit for high-local-content vehicles.
- Phase 2 (Starting May 2026): The credit drops to 2.5%.
- The Cliff: By May 2027, the relief program is scheduled to vanish.
This is why GM is frantically moving production. They shifted the Chevy Blazer and Equinox assembly from Mexico back to U.S. plants. It wasn't just for the "Made in USA" badge. It was a survival move to dodge the tax man.
The $4 Billion Price Tag
By late 2025, GM narrowed down the damage. They expect auto tariffs General Motors pays to land between $3.5 billion and $4 billion for the 2026 fiscal year.
That is actually better than they expected.
Earlier projections had that number closer to $5 billion. They managed to trim a billion dollars off the bill by "internal restructuring." In plain English? They fired people, closed some lines, and squeezed suppliers to move their factories to the States.
It’s a brutal trade-off. You save money on tariffs but spend billions on new factory floors in Michigan and Tennessee.

The EV Meltdown and the Tariff Connection
While the tariffs were supposed to protect American EVs, they might have accidentally helped kill the first wave of them.
Last year, the $7,500 federal EV tax credit evaporated. Combine that with the rising cost of imported battery materials due to—you guessed it—tariffs, and the math stopped working for consumers. GM took a massive $6 billion charge in January 2026 just to account for the fact that their EV plans aren't panning out like they hoped.
They are pivoting back to what they know: big V-8 engines.
They just dumped $888 million into a New York plant to build next-gen internal combustion engines. It feels like a reversal, but when a 25% tariff is breathing down your neck, you build what people will actually buy today.
What This Means for Your Wallet
If you’re looking to buy a car in 2026, the "tariff tax" is real. Analysts at AlixPartners and CarEdge have been tracking this closely. The average new car price is flirting with the $50,000 mark for the first time in history.
- The Buick Envision: This is the poster child for tariff pain. It’s made in China. Even with some loopholes, it’s facing heavy duties that make it a tough sell compared to a few years ago.
- The "Light" Truck Tax: Because of the 25% "Chicken Tax" and the new Section 232 duties, pickups are the most vulnerable. Expect to pay at least $2,000 to $3,000 more just to cover the manufacturer's tariff costs.
- Insurance Hikes: This is the one nobody talks about. When it costs 25% more to import a replacement bumper or a headlight from overseas, your insurance company raises your premiums. You’re paying for the trade war even if you aren't buying a new car.
The 2026 USMCA Review: The Next Big Hurdle
Everything we know right now could change. The USMCA (the "new NAFTA") is up for a mandatory review in 2026.
Volkswagen and other giants are already screaming that the current U.S. tariffs violate the treaty. GM is being more diplomatic—Mary Barra has to stay on the good side of the administration—but behind the scenes, their lobbyists are working overtime.
They want the rules to stay predictable. The worst thing for a car company isn't a high tariff; it’s a tariff that might change tomorrow. You can't plan a five-year factory build on a "maybe."
Actionable Steps for the Road Ahead
If you're following the auto tariffs General Motors is navigating, you shouldn't just watch the news. You should change how you shop.
Check the VIN and the Door Sticker.
Don't just trust the brand. A "domestic" car might have a high percentage of imported parts that make it more expensive to repair. Look for the "Parts Content" label on the window sticker (the Monroney label). The higher the U.S./Canadian content, the more insulated that specific model is from future tariff spikes.
Watch the "MSRP Offset" Calendar.
Since the relief credit for manufacturers drops in May 2026, there’s a high probability that automakers will hit consumers with a mid-year price increase to cover the difference. If you're planning a purchase, the first quarter of 2026 is likely the sweet spot before the next round of "price adjustments" kicks in.
Consider Certified Pre-Owned (CPO).
Used cars don't carry the same immediate tariff burden as new imports. If the price of a new Silverado is $5,000 higher than it was two years ago, the value proposition of a 2023 or 2024 model becomes significantly stronger.
Monitor the Supreme Court.
There is a case currently moving through the system regarding the legality of using the International Emergency Economic Powers Act (IEEPA) to set these tariffs. A ruling against the administration could see a sudden drop in parts costs, which might—just might—lead to better dealer incentives later in the year.
The era of cheap, globally-sourced car parts is over for Detroit. GM is betting billions that they can transform into a purely North American powerhouse. Whether the American consumer is willing to pay the premium for that transformation is the $4 billion question.
