The Illinois General Assembly is considering a bill that would require written authorization from consumers for aftermarket crash parts to be included in collision repair estimates.

House Bill 4926, introduced by Rep. Linda Chapa LaVia, also would amend the Illinois Insurance Code and the Automotive Collision Repair Act by forbidding body shops and installers from using “repair specifications or procedures that are not in compliance with the original equipment manufacturer for those parts unless authorized by the customer in writing.”

Currently, Illinois law requires insurers and body shops to provide written notice to consumers if they’re specifying aftermarket parts for collision repairs.
