What to Keep an Eye On

The May 3 deadline for details on auto parts tariffs is quickly approaching—and it’s a big one for the aftermarket. Over the next few weeks, the landscape could shift significantly. SEMA is actively engaging with the Trump Administration to make sure our industry’s priorities are heard, especially around how these tariffs could affect members’ ability to provide top-tier, American-made products to their customers.

President Trump’s order also opens the door for expanding the list of affected parts. The Secretary of Commerce now has 90 days to create a process for reviewing requests to add more auto parts to the tariff list.

Auto parts manufacturers and industry associations will be allowed to submit these requests if they believe rising imports pose a threat to national security. Once a request is received, the Secretary must consult with the U.S. International Trade Commission and Customs and Border Protection before deciding—within 60 days—whether those parts should face tariffs as well.

The CARS Rule Overturned: What It Means for Auto Dealers and Consumers

In a major win for the auto retail industry, the 5th U.S. Circuit Court of Appeals has struck down the Federal Trade Commission’s (FTC) Combating Auto Retail Scams (CARS) Rule, citing procedural violations in its enactment. The ruling, delivered in favor of the National Automobile Dealers Association (NADA) and the Texas Automobile Dealers Association (TADA), effectively nullifies regulations that were set to impose stricter disclosure and consent requirements on dealerships nationwide.

The now-invalidated rule sought to enhance transparency in vehicle sales by prohibiting deceptive pricing, hidden fees, and misleading financing terms. While consumer advocates praised the initiative, dealers argued that the rule added unnecessary compliance burdens that could disrupt sales processes and increase costs.

Although the FTC has the option to appeal the decision to the Supreme Court, its next steps remain uncertain. For now, dealerships can continue their current sales practices without the immediate threat of additional federal oversight.

FTC Clarifies Customization Concerns

One of the unintended consequences of the CARS Rule was confusion surrounding its impact on vehicle customization. Some dealers began restricting aftermarket add-ons—such as window tinting, paint protection, and performance upgrades—out of fear that these products might be deemed “junk fees” under the new regulations. In response, the FTC issued a formal clarification, stating that the rule did not prohibit dealers from offering products that provide real value to consumers.

This means that as long as add-ons are properly disclosed and benefit the buyer, dealerships can continue offering customization services without regulatory pushback. This is welcome news for enthusiasts and everyday buyers alike, as aftermarket upgrades remain a key part of vehicle ownership.

With the CARS Rule now overturned, dealerships regain more flexibility in their sales and financing processes. However, the ruling doesn’t eliminate state-level consumer protection laws or the FTC’s broader authority to regulate unfair business practices. For both dealers and consumers, the key takeaway is that transparency and fair dealing will remain at the heart of a successful automotive sales experience. 

California’s Proposition 65 Updates

California’s Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, continues to expand its list of regulated chemicals. This law requires businesses to disclose the presence of chemicals known to cause cancer, birth defects, or reproductive harm. In 2025, new chemicals are being added, some of which are commonly found in automotive products like adhesives, cleaners, and coatings.

What’s Changing in 2025?

  • Expanded Chemical List: Additions include industrial solvents and substances used in automotive paints and sealants.
  • Stronger Enforcement: Increased penalties for non-compliance, with a focus on manufacturers and distributors supplying California.
  • Consumer Awareness: Consumers are becoming more aware of Proposition 65 warnings, demanding safer alternatives.

Implications for the Aftermarket

  1. Product Reformulation Costs:
    Manufacturers must reformulate products to eliminate newly regulated chemicals, a process that may involve significant R&D investment.
  2. Labeling Requirements:
    Packaging and product descriptions must include updated warnings, increasing operational and design expenses.
  3. Market Opportunities:
    Companies offering eco-friendly alternatives can use compliance as a competitive advantage to appeal to environmentally conscious buyers.

Actionable Steps

  • Audit your product inventory to identify items affected by new regulations.
  • Invest in reformulation to meet compliance standards while maintaining product performance.
  • Educate customers about Proposition 65 compliance and the benefits of safer products.

Outdoor Act To Boost Off-Road Interest 

The Outdoor Recreation Jobs and Economic Impact Act, commonly referred to as the Outdoor Act, aims to promote investment in outdoor recreation infrastructure. It also encourages the production of goods catering to outdoor enthusiasts—a category where the automotive aftermarket thrives.

How the Outdoor Act Impacts the Industry

  • Infrastructure Investments: Expansion of national parks and recreation areas increases demand for off-road and adventure vehicles.
  • Sustainability Focus: Consumers gravitate toward companies adopting eco-friendly practices in line with the act’s goals.
  • Emerging Markets: Growth in overlanding, camping, and outdoor activities boosts demand for specialized accessories.

Opportunities for Aftermarket Businesses

  1. Increased Demand for Accessories:
    Roof racks, lift kits, winches, and other off-road gear are becoming essentials for adventure seekers.
  2. New Product Lines:
    Businesses can diversify offerings with innovative products like portable solar panels and all-weather storage solutions.
  3. Marketing Alignment:
    Highlighting eco-conscious manufacturing processes can resonate with environmentally aware consumers.

Next Steps

  • Expand inventory to include outdoor-focused products like overlanding gear.
  • Collaborate with outdoor organizations to tap into niche markets.
  • Align marketing strategies with sustainability themes to attract eco-conscious buyers.

California’s Vehicle Safety Systems Inspection Program (VSSI)

California is implementing the Vehicle Safety Systems Inspection Program (VSSI) in 2025. This program mandates inspections for advanced driver-assistance systems (ADAS), such as automatic braking and lane-keeping assist.

What is VSSI?

VSSI ensures that ADAS features function as intended, addressing safety concerns related to poorly calibrated systems. These inspections will apply to vehicles during routine smog checks or annual maintenance reviews.

Impacts on the Aftermarket

  1. Demand for Calibration Services:
    Shops must invest in ADAS calibration equipment to meet inspection standards.
  2. Aftermarket ADAS Standards:
    Manufacturers of aftermarket ADAS products must ensure compatibility with inspection criteria, increasing design complexity.
  3. Specialization Opportunities:
    Repair shops offering ADAS diagnostics and calibration will gain a competitive edge in this growing segment.

How to Prepare

  • Train technicians to handle ADAS calibration and diagnostics.
  • Upgrade shop equipment to meet VSSI requirements.
  • Partner with ADAS component manufacturers to ensure compliance with inspection standards.

Corporate Average Fuel Economy (CAFE) Standards

The 2025 update to Corporate Average Fuel Economy (CAFE) standards mandates higher fuel efficiency across automotive fleets. These changes impact the aftermarket by shifting consumer preferences toward lighter, more efficient vehicles and eco-friendly accessories.

Key Changes in CAFE Standards

  • Higher MPG Targets: Automakers must achieve greater efficiency across their vehicle lineups.
  • EV Integration: Increasing reliance on hybrids and electric vehicles (EVs) to meet efficiency goals.
  • Supply Chain Shifts: Greater demand for lightweight materials and advanced drivetrain technologies.

Aftermarket Opportunities

  1. Lightweight Components:
    Body kits, low-rolling-resistance tires, and aerodynamic accessories are poised for growth.
  2. EV-Specific Products:
    The rising popularity of EVs creates demand for charging stations, adapters, and battery upgrades.
  3. Performance Optimization:
    Fuel-saving performance tuners will attract eco-conscious buyers looking to improve efficiency without sacrificing power.

Next Steps for Businesses
