April 23, 2026: "MATSUI, GRIFFITH INTRODUCE BILL TO PROTECT AMERICAN PUBLIC WITH SAFE FLAMMABILITY STANDARDS". The release says Matsui and Griffith introduced the bipartisan Motor Vehicle Flammability Standards Study Act of 2026, requiring NHTSA to conduct a study identifying potential safety risks and hazardous chemicals used as flame retardants in the interior of motor vehicles and to evaluate alternative standards.

Matsui publicly announced introduction of the bill during the lookback window, but the available official evidence shows only introduction, not enactment or completion of the required NHTSA study.

The committee substitute for H.R. 7389 includes Sec. 118, "Study on motor vehicle flammability hazards," showing the study concept was folded into broader motor-vehicle legislation.

Official House markup text shows the flammability-study idea advanced into a committee substitute, but this is still legislative drafting rather than enactment or an NHTSA study.

The committee repository lists H.R. 7389 as having reached final passage in the May 21, 2026 Energy and Commerce markup, after the substitute containing the flammability-study provision was posted.

This is strong evidence of committee-level progress on the broader vehicle modernization bill that carried the study provision, but not final House passage or implementation of the Matsui claim itself.
