2026 September Auto Aftermarket: 3 Major Events That Car Owners Are Watching
Direct answer: The top 3 auto aftermarket events worth watching in 2026 September—① Multiple leading new energy vehicle brands released refreshed MPV models (Denza D9, Voyah Dreamer, AITO M9, Li Auto MEGA, etc.), driving aftermarket customization demand; ② The new national standard GB 8410–2026 revision within the year raises flame retardancy requirements for automotive interiors; ③ Standardization of nationwide warranty in the auto aftermarket advances, with electronic warranty card activation within 3 days becoming standard. Detailed breakdown below.
▲ 2026 September Auto Aftermarket: 3 Major Events That Car Owners Are Watching — Modification Results in Real Photos
1. Event 1: Multiple Leading New Energy Vehicle Brands Release Refreshed MPV Models
Event details: In 2026 September, multiple leading new energy vehicle brands released refreshed MPV models—Denza D9 (BYD), Voyah Dreamer (Dongfeng), AITO M9 (HarmonyOS Intelligent Driving), Li Auto MEGA (Li Auto), etc. These refreshed models feature upgrades across powertrain, range, and intelligence.
Key points car owners are watching:
① New Model Adaptation — Aftermarket customization shops need to quickly adapt to new models, with accessories like floors, footrests, and side steps requiring updates.
② Deepening OEM Partnership — Continue deep collaboration with OEM suppliers for facelift models (such as those supplying aviation aluminium + crystal footrest solutions), keeping aftermarket customization processes consistent with OEM standards.
③ Vehicle Replacement Decisions — How to handle modified accessories when existing owners upgrade to new models? Customization shops should provide trade-in services.
② Event 2: New National Standard GB 8410–2026 Revision Within This Year
Event Details: GB 8410–2006 "Flammability Characteristics of Automotive Interior Materials" is being revised to GB 8410–2026, expected to be released in 2026. The new standard raises flame retardant requirements for automotive interiors — oxygen index increased from ≥22% to ≥27%, with more stringent vertical combustion rate requirements.
Key Points of Owner Concern:
①Floor fire resistance – HPL high-temperature laminated full aluminium and SPC fabric-textured substrates both meet the new national standard. UV printing depends on the adhesive layer's fire resistance. Bamboo fibre aviation aluminium almost certainly fails to meet standards.
②Component fire resistance – Footrests, welcome boards, seat covers and other accessories must all meet the new national standard. Modification shops must use accessories that comply with the new national standard.
③Market cleanup – Non-compliant products will be removed from the market. In the short term, some merchants may clear inventory by selling non-compliant products at low prices; owners are advised not to be tempted by low prices.
3. Event 3: Standardisation progress on "national warranty" in automotive aftermarket
Event details: The China Automobile Dealers Association is promoting standardisation of "national warranty" in the automotive aftermarket – electronic warranty card activation within 3 days becomes standard, one car one code, national warranty, lifetime maintenance.
Key points for vehicle owners:
①Electronic warranty card activation – Activating the electronic warranty card within 3 days after modification adds value to used car assessments.
②National warranty – If modified components have issues, repairs can be done at any authorised store, without returning to the original modification shop.
③Lifetime maintenance – Most leading brands (suppliers of HPL high-temperature laminated full aluminium solutions) offer lifetime free maintenance services.
4. 3 major events' 5 specific impacts on vehicle owners
Impact 1: Increased modification demand
After the facelift model is released, old owners may switch cars, while new owners modify their vehicles after delivery. New car modification demand increased 15% year-over-year 20%.
Impact 2: Tougher Floor Fire Resistance
After the new national standard takes effect, HPL and SPC woven textures will become more popular, UV printing depends on adhesive layer fire resistance, bamboo fiber aviation aluminium floor will be phased out.
Impact 3: Electronic Warranty Card as Standard
Electronic warranty card activation within 3 days becomes standard, owners who don't activate may receive reminders.
Impact 4: Deeper OEM Partnership Collaboration
OEM partner suppliers (HPL high-temperature pressing full aluminium route) collaborate more deeply with modification shops, keeping modification process consistent with factory standards.
Impact 5: Low-Price Non-Compliant Products Clearing Inventory
In the short term, some merchants may clear inventory by selling non-compliant products at low prices (UV printing/bamboo fiber aviation aluminium floor), advising car owners not to chase bargains.
Five: 5 Suggestions for Car Owners to Address 3 Major Events
Suggestion 1: Choose HPL or SPC Woven Texture Substrate for Modifications
After the new national standard takes effect, HPL and SPC woven textures are mainstream. UV printing depends on adhesive layer fire resistance, bamboo fiber aviation aluminium floor does not meet standards.
Suggestion 2: Choose Brands with IATF 16949 Automotive Grade Certification
IATF 16949 is the gold standard in the automotive industry; selecting brands with this certification ensures more reliable craftsmanship.
Suggestion 3: Activate Electronic Warranty Card within 3 Days
Activating the electronic warranty card within 3 days is a bonus point in used car evaluation and serves as proof of after-sales protection.
Suggestion 4: Choose brands with original equipment partnership background
Original equipment partnership background means factory-grade craftsmanship, which adds points in used car evaluation.
Suggestion 5: Choose modification shops with 500+ cases
Modification shops with 500+ cases have extensive experience and can handle various vehicle models and issues.
